Why is Laboratory Apparatus Important?
The importance of laboratory apparatus is relative and varies widely by:
- Field or industry ( medical, pharmaceutical, etc.)
- Institutions (educational institutions and research centers)
But more specifically, the lab instruments make it easier for conducting various experiments.
Scientists require the equipment for performing multiple tests, speculations, data collection/ analysis, and concluding/ findings.
Without such instruments, it would be undoubtedly tricky.
In educational institutions, it’s as well essential to expose students to the hands-on science laboratory equipment.
It is not only for the sake of compliance with the curriculum but also to instill some long term skills.
Even in tertiary education institutions, learners proceed further into high-level scientific research while pursuing a related science course.
So clearly, without the lab instruments, it isn’t possible to do all that.
What Should You Consider When Buying Lab Instruments?
Buying suitable lab equipment helps you get quality for your money.
That aside below are a few factors you need to delve into before making any quotation.
- Specify the type of laboratory instrument you want

What are the Units of Measurements in Laboratory Instruments?
Handhold thickness tester
Scientists worldwide prefer to peg all the measurements in line with the International System of Units( SI, derived from the French Systeme International d’unites).
SI is the metric system of units that’s preferable for use in science, industry, pharmacy, and medicine.
However, in other conventional measurement scenarios and specifically in the United States, scientists use the “imperial” system, which includes such units as gallons, miles, feet, and pounds.
The International System of measurements (SI) has got three categories commonly used for every basic unit of measure.
They include Measured Quantity, Unit Name, and Unit symbol.
The seven base units include:
|Quantity||Unit Name||Unit Symbol|
|Quantity of Substance||Mole||mol|
SI Unit Prefixes
By modifying a set of simple prefixes, It’s easier to express the basic SI units into fractions and multiples of basic units.
Other standard units( Volume, Density, Acceleration, Force) are as well derivable by combining both the base units and prefixes.

What is Laboratory Quality Management?
As per the ISO 9000:2015 quality management system- fundamentals and vocabulary, we can define QMS by singling out the meaning of each word distinctively.i.e
System: a set of interconnected or interacting elements.
Management– refers to the coordinated programs to direct and control an organization.
Quality: extent in which a set of inherent features of an object (product, service, process, person, resource, etc.) meets the requirements.
Therefore, QMS refers to the planning, business, and control exercise performed on a lot of components to accomplish quality.
Concerning the laboratory, the precision, unwavering quality, and practicality of the expository outcomes revealed characterize its class, and all parts of diagnostic tasks ought to be controlled.
WHO recommends which Quality Standards for Lab Instruments?
The WHO recommends and enshrines its quality standards through the implementation of the International Organization for Standardization( ISO), which sets rules.
The following ISO standards address relevant issues in the lab instruments.
- ISO 9000- It deals with the research quality frameworks that deal explicitly with quality administration issues.
- ISO 17025 and 15189: – addresses necessities for testing and alignment labs and medical labs individually.
- ISO 17025: 2005 Comprises five components: scope, regularizing references, terms and definitions, management requirements, and specialized necessities. The last two elements being the primary segments.
The management necessities spread determinations of the association, the board framework, document control, survey of solicitations, tenders, and contracts, subcontracting of tests and adjustments, acquiring administrations and supplies, grievances, upgrades, therapeutic activity, preventive activity, control of records, internal reviews, and the executive audits.
Specific necessities manage staff issues, space, and ecological conditions, test, and adjustment strategies, and strategy approval, hardware, estimation detectability,examining.treatment of tes tand alignment things, guaranteeing the nature of test and adjustment results and revealing the outcomes.

What is Clinical Laboratory Improvement Amendments (CLIA)?
The CLIA of 1988 is the federal regulatory standards of the United States that apply to all the services offered by the clinical laboratories.
Plus the regulation requires all those labs to be certified by their respective states together with the center for Medicare and Medicaid Services (CMS).
The CLIA must be adhered to before the lab accepts any human samples for medical purposes except for clinical trials and some basic research.
Besides, laboratories can acquire several kinds of CLIA certificates depending on the types of diagnostic tests they perform.
The main goal of the CLIA is to guarantee the exactness, unwavering quality, and practicality of test outcomes paying little heed to the organization performing the test. Most laboratory-developed tests follow this program.
Three government offices are in charge of CLIA, each playing a unique function in ensuring quality laboratory testing.
- The Food and Drug Administration (FDA)
- Center for Medicaid Services (CMS)
- Center for Disease Control (CDC)
Lab Instruments Measure which Parameters?
Instrumentation is a group term for all the measuring instruments used for indicating, calculating, and detailing physical quantities comprising of the rate of flow, temperature, distance, pressure or level.
The lab instruments measure a wide range of parameters. They include:
- Pressure,ie. Differential, static or blood
- Levels of liquids, fluids, etc.
- Chemical composition
- Chemical properties
What is Calibration Test?
Calibration test is the process of comparing unknown value of lab instrument to known standard value.
The known standard value is always the reference point.
The reference equipment of known value has to be specifically linkable to the apparatus calibrated per the ISO/IEC 17025.
However, you should note that some quantities, the reference doesn’t necessarily imply to a device, but rather it could be mass, physical text, reference liquid gas or mechanical part.
Why Calibrate Lab Instruments?
Whatever, the industrial application of the instrument, it is undoubtedly vital to perform calibration of instruments.
Several reasons prompt this, amongst them, include:
- Regulation standards stipulate regular calibration of the lab instruments. The measures include ISO 9000, ISO 14000, etc.
- The correctness of all the measurements and respective devices tends to deteriorate with time.
- A quality system needs calibration.
- Monetary factors –At the point when the cash transfer or invoicing depends on estimations, unmistakably, the more exact the estimates are, the more precise the cash move.
- To guarantee the quality of the produced products.
- Safety precaution. Calibration ensures the safety of both the customers and employees. The employees’ safety is directly proportional to the work area/ plant. The customer’s safety, especially in the food and pharmaceutical industry, is a significant concern.
- Environmental conservations. It is possible to measure the various emissions from an industrial plant with the aid of estimation gadgets; consequently, keeping these exact with frequent calibrations keeps a clean surrounding.
How do you Calibrate Lab Instruments?
You can calibrate laboratory instruments by:
i. Calibration by examination using a source of known value. In this calibration process, you will adjust the instrument parameters according to match the reference value.
ii. Calibrate by examining DUT estimation alongside the measurement from an adjusted reference standard.
Again, this technique involves the DUT calibration with a source of defined natural value for example melting point and freezing temperatures of pure water.
What are the Types of Calibrations for Lab Instruments?
In modern technology, it is possible to calibrate instruments by the use of generally two types of calibration techniques, i.e. manual or automatic processes.
Tablet hardness tester
· Manual Laboratory Instrument Calibration
In this category, you need two instruments, ie. DUT and a reference device.
Finally, you would compare the results between the two and adjust where necessary.
For example; to calibrate pressure gauge; you need to connect the device under test to another standard reference master gauge.
Plus you would require an adjustable pressure source.
After that, you would adjust the DUT to zero points, make multiple fine-tuning and adjustments, while manually keeping the records.
· An Automatic Calibration for Laboratory Instruments
This procedure involves the usage of an electronic control unit.
For example, a pressure intensifier for compressing gasses such as nitrogen, or pressure transducer to sense the correct levels in a hydraulic accumulator.
Besides, the automatic unit may also comprise an automated data collection and recording.
Aside from the automatic and manual way of calibration, we may consider another two types of procedures:
- Traceable calibration certificate
- ’UKAS calibration certificate
· A Traceable Calibration Certificate
It involves referencing your tools against pre-calibrated systems to calculate a degree of mistake. The benefit of this technique is; it’s high regard for much flexibility in conducting testing and adjustments.
Meaning, any instrument that deviates from the set specification is re-adjusted and re-tested.
· UKAS calibration Certificate
The UKAS calibration can only be conducted by a lab that fulfills the requirements of the ISO/IEC 17025.
That is after being awarded a UKAS calibration certificate.
For this technique, the instruments have to comply with the set international standards.
Failure to which the devices must undergo a new adjustment before you can re-send them for calibration.
What is the Difference between Calibration and Verification in Lab Instruments?
Calibration is the dual procedure of measuring and adjusting the precision of an instrument relative to a recognized measurement standard. It is also known as a calibration standard issued by the bureau of standards, for example, NIST.
Verification – this the procedure intended to guarantee that your device or process continues to perform its intended function from the outset.
Usually, it is an internal procedure focusing on the mandate of maintaining and stabilizing the performance of an instrument or method for an extended period.
How Often Should You Calibrate Laboratory Equipment?
Most industries perform calibration annually after which they acquire a calibration certificate for retaining as evidence of quality standards.
Besides, technicians advice a shift in calibration from yearly to a few times within a year or maybe upgrade to more technically upright instruments.
Regardless of all that, you may consider some of the following factors when determining a suitable calibration interval:
- The criticality of the measurement involved.
- Manufacturer’s recommended interval.
- The historical stability and background information of the instrument.
- The involved Regulatory demands and quality system.
- Reasonable costs and consequences incurred during failed calibration.
- Consider the tolerance process requirements of the instruments.
- The accuracy level of the instrument.
- The workload of the related appliance i.e. a frequently used instrument needs frequent calibration.
- Environmental factors; instruments operating in adverse conditions should be often calibrated.
How do you Determine Resolution in a laboratory Instrument?
Weighing a patient – Photo courtesy: Cosmo
Resolution is the ability of the measurement device to detect and record minute variation in the traits of the result.
For an analog-to-digital (A/D) converter, the resolution could mean the contrast between the highest recorded signal to the lowest measurement.
Therefore, it means that an instrument with high resolution can record up to microscopic measurement.
However, it doesn’t necessarily translate into greater accuracy and vice versa.
So how do we determine resolution?
i. Pick several devices with pre-known values over a range from maximum to minimum values to make a determination in the laboratory.
ii. Begin with the two most remote devices and measure each.
iii. After that, measure the two instruments with the second most significant difference.
iv. Repeat the preceding procedure repeatedly till you come by two equipment that gives similar consistent results.
v. Finally, the variation between the two values obtained above with the instruments gives an approximate value of resolution.
What is Precision in Laboratory Instruments?
The precision of a lab instrument refers to the degree at which measurements are reproducible or repeatable over a range of conducted tests/ recordings.
For that matter, we can sometimes simplify precision into two inferences,i.e:
- Repeatability –continuously repeating the same measurement within the shortest period possible while noting the variation. However, all the conditions must be constant by using a similar device and operator.
- Reproducibility – The difference in results due to similar measurement procedures while using different instruments and operators over more extended periods.
Do Accuracy and Precision Mean the Same in Laboratory Equipment?
Accuracy is the measure of the extent of closeness of a result to the real/ correct value of the same measurement.
Whereas, the precision of a measurement refers to the general consistency of the costs.
What should you Consider when Choosing Laboratory Analytical Instruments?
You should consider the following:
- Accuracy; since analysis is a sensitive issue, you cannot miss accurate measurements and recordings. It would be fatal.
- Sensitivity; the instruments need to be quick to detect and record even the slightest of changes within a sample.
- Resolution; as initially outlined, you need a suitable instrument should that take count of any variation in the derived results.
