are tools and devices used by scientists and researchers to carry out
work in a laboratory. Laboratory equipment entail a range of gadgets
and tools for various purposes. For example, Bunsen's burners used to
heat the reactants, microscopes to magnify objects and life forms
invisible to the human eye because they are so tiny and other equipment
viz. spectrophotometers, calorimeters, special purpose glassware are
all classified as laboratory equipment.
Generally, laboratory equipment is needed to conduct scientific
experiments or for measurements or to gather data. Larger and
sophisticated equipments are generally referred to as scientific
Laboratory centrifuge is an equipment powered by a motor, which spins
liquid samples at high speed. laboratory centrifuges are essentially
available in two sizes. The larger units are known simply as
centrifuges, comprise centrifuge tubes which contain the samples. The
smaller ones on the other hand are known as microcentrifuges or
microfuges and they make use of microfuge tubes to store the samples.
Centrifuges are used to separate substances of higher density from
those with lower density. They achieve this through the process of
sedimentation. As they rotate the samples at high speeds the
constituents of varying densities contained in the samples are
separated. Different types of centrifuges accomplish different types of
centrifugation viz. differential centrifugation, isopycnic
centrifugation , sucrose gradient centrifugation, etc.
Laboratory microscopes refer to
instruments used for viewing objects
that are too small to be seen by an unaided eye. While the study of
small objects is known as microscopy, the word microscopic refers to
something that's very small and not visible to a naked eye.
Microscopes are often classified as either, optical microscopes,
electron microscopes, or scanning probe microscopes. The optical theory
microscopes work on the principles of magnification and make use of
optical lenses. Also they use visible wavelengths of light, while the
electron microscopes use electron beams. The electron microscopes are
further classified as Scanning electron microscope and Transmission
Laboratory consumables refer to all the items and equipment that get
used up in the process of carrying out experiments. There are a number
of laboratory consumables used for a myriad purposes. Some examples of
consumables include Baskets, Dishes, Jugs, Paper products, Specimen
containers, Trays, Rubber Stoppers, Universal Containers, Ice buckets
& trays, Scoops, Buckets, Dippers, Spatulas, Analyzer Cups,
Counting Vials, Cuvettes, Nitrile Gloves, Parafilm, Sample Cups,
Spatulas, Weigh Boats, etc.
Laboratory Incubators are devices meant to regulate the
humidity, and other conditions in which a microbiological culture are
growing. Laboratory Incubators
vary in their sophistication. For instance, the simplest may just be
insulated boxes accompanied by an adjustable heater with a capacity to
vary the temperature from 140 to 150 °F or more. On the other hand more
complex incubators can include the ability to lower the temperature as
well, coupled with an ability to control humidity and CO2 levels.
Advanced incubators also have a timer, which can sometimes be programed
to vary parameters such as temperature, humidity levels, etc in a
cycle. Furthermore, their sizes also range from being tabletop to units
the size of small rooms.
Laboratory mixers are a device used in laboratories to mix liquids and
solutions. The construction of a typical mixing device entails a drive
shaft attached to a container holder. Further, a motor powering the
device cause the holder to oscillate rapidly, mixing the solution.
Additionally, mixers typically come with a builtin speed control to
adjust the speed of oscillation based on the types of solutions to be
Laboratory Water Bath
A laboratory water bath or a heated bath is a piece of equipment used
to carry out a chemical reaction to an increased temperature.
Generally, a water bath entails a fluid on an open metallic pot in
which the container holding the substances to be heated are immersed.
The most common fluids used for the bath are water and oil. Water baths
are needed to allow reactions to take place above 100 °C, on the other
hand an oil bath is used for temperatures in excess of 100 °C.
For the reaction to be carried out in the reaction chamber, the chamber
viz. erlenmeyer flask, florence flask, or a beaker, containing the
solution is immersed in the heated bath. In addition a thermometer
attached to the bath keeps a track of the temperature. Water
baths come in different sizes with comprising both analog and digital
controls. The reaction chambers are made of rugged, materials that are
Laboratory Equipments - Buying Tips
The very quality of laboratory equipments and supplies determine how
effective and safe these products are and this in turn affects the
quality of medical or scientific research carried out. Using
substandard laboratory equipments pose a safety hazard, hence the
importance of the quality lab equipments can’t be overstated.
The following are tips that would help you to procure quality laboratory equipment and supplies.
1.Establish the integrity of the source prior placing the order.
2.Establish a list of approved suppliers.
3.Require that any alternative source of supply provides the following as a minimum:
a.A pedigree back to the previous source.
b.Certification that it is not a diverted product.
c.Certification that any actions by the alternative source will not alter any original manufacture warranties or guarantees.
4.Be wary if a product is being offered at an unusually cheap price.
5.Check for subtle changes in the product’s package (compare with
previously purchased products), notwithstanding legitimate parallel
Laboratory equipment/instrumentation used in science and medical
laboratories has grown in importance with the increasing number of
medical and scientific research facilities in the health care industry
The UK's industry has developed alongside the country's industrial
revolution and is an indicator of the country's science base. UK
commands about 7 per cent of the world market and the sales of lab
equipment in 2005 was worth US$ 4.30 billion.
The trends fueling the growth of the industry include miniaturization
and automation. For the most part consumers are demanding lab equipment
that occupies less space and and automation for inducing greater
efficiencies in their processes. In addition, portability of the
equipment too is on their minds.
Aside from the growth in the west, countries in the Asian continent
such as China and India will have a bigger role to play as supplier as
many suppliers have already outsourced equipment production to
facilities in these countries.
