There are different balances that are used
differently. Each of the balances has its distinct features and is used
in different labs. This article discusses of the most used laboratory
balances like analytical balances or top-loading balances.
In any laboratory, balances are important.
These balances are used to measure and count items
and materials for experiments. There are different balances like analytical balances precision, top-loading balances, etc. These balances have different purposes and are used in differe4nt labs.
These balances have higher degrees of
readability and higher accuracy. Therefore, you can get exact results
and measurements for performing an experiment. Here
are some well-used balances in the laboratories-
Portable Balances–
These balances are portable and can be
carried easily. These balances are used for fieldwork and other
purposes. Portable balances have a user-friendly design and
can weigh a large number of samples easily. It offers many features like
piece counting, dynamic weighing, unit conversion, etc. These balances
have sealed keypads and details steel platforms for easier maintenance.
Analytical balances–
Analytical balances are common in life
sciences and biological laboratories. This balance is specially designed
to resist all the external forces like an air current. It has a
glass-
enclosed chamber where samples are kept and weighted. These
balances need regular calibration and proper maintenance. Hence, often analytical balances
are kept in a different room. This is to ensure that there is no
disturbance like foot traffic, chemical spills, flying objects.
Vibrations or other disturbances like birds or small animals or air.
These balances are sensitive and must be handled
carefully. Analytical balances have an antistatic mat inside them. The
mat is for higher accuracy. Some analytical machines also come with
automatic recalibration for convenience. Analytical measures are best
for weighting the smallest amount of samples, unstable samples like
liquids, small samples of cells or small insects and animals. This
balance offers higher decimal accuracy and also has a better precision
rate. Analytical balances should not be kept in a dirty room. This is
because dirt and dust can affect the weighing capacity. It also provides
facilities like dynamic weighing, counting of unstable and smaller
samples, etc.
Top-loading balances–
Top-loading balances are used to
weight substances where higher precision is not required. For example,
if you do not need the upper margin or error to be less than 0.05mg then
you can use it. This balance does not offer protection from air
currents and can weight in low range.
Microbalances–
Microbalances or semi-micro balances are
used to weigh even the smallest of samples. It can accurately weigh the
1/100 portion of a milligram. Hence, these special balances are used in
case of sensitive experiments or in case of measurement of coating
materials, etc.
Here you get an overview about different
types of balances and the usage of those. Such balances will help a lot
in laboratory works.
Global Lab Supply is an eminent company
which has been supplying different laboratory and clinical equipment to
their clients for a long time. You can contact this company for buying
the best suitable balance for your lab.
