Analytical balances
An analytical balance is a type of laboratory balance characterized by a
maximum accuracy of 0.001 mg. For an analytical balance, the
measurement technology should be as accurate as possible, since even
with such accuracy even a slight deviation from the correct measurement
technology (storage of the scales, use in the sun, an unstable table or
even a building oscillation) cause an error in the analytical
measurement of the balance, which leads to an error in the analytical
calculations. For analytical balances, I am a glass showcase that
protects the weighing platform and the weighing object on it from the
effects of the light flow in the room on the scales. For analytical
balances, the most important metrological parameters are the maximum
load (maximum load capacity), minimum load capacity, below which
accuracy is not achieved. Electronic analytical balances are used in
scientific laboratories in the chemical, pharmaceutical and other
industries where high-quality analysis of various materials and
substances is required. Analytical scales are also used in metrology
laboratories and in the development of nanotechnology. Since the
analytical balance is a very accurate and relatively fragile product,
only trained personnel should work on the laboratory electronic
analytical balance. When unpacking, make sure that the balance is not
damaged. The original packaging of the analytical balance with
additional elements must be stored and used if it is necessary to move
the analytical balance to another place. It is very important to
maintain the level when installing the analytical balance. The level of
weights is controlled by the weight of the legs. If the analytical
balance has undergone a rapid temperature change due to its
transportation, it is recommended that the electronic balance remain at
room temperature for at least two hours before connecting to the
network. This is due to possible condensation in the body of the
analytical balance. Electronic analytical balance must be heated for at
least 2 hours before weighing, after a long period of shutdown, as well
as the first time you turn it on. If the analytical balance does not
have an internal calibration device, the analytical balance should be
checked with the balance. To align the temperature in the analytical
balance with the ambient temperature, the analytical balance window
should be open 20-30 minutes before weighing. To exclude the possibility
of electrostatic discharge, it is advisable not to use plastic and
glass containers during weighing, especially if the humidity is below
30-40%. The use of cotton gloves is a must when using an analytical
balance. The temperature of the weighing sample and weighing cup should
be equal to room temperature. If the temperatures are different, air
flow and moisture are formed. Before loading weighing materials, make
sure that the analytical balance shows 0. If not, press the 'TARA'
button to place the weighing samples in the center of the weighing
container. SIA 'BK SYSTEMS' (svuveikals.lv) offers laboratory scales
from all over the world. CORN and AXIS from Poland. Some models from CAS
(South Korea), RADWAG (Poland) are also available. In particular, the
company wants to highlight the production of AXIS laboratory scales,
which are also sold under the brands of other world-famous companies. If
the laboratory balance is intended for use in pharmaceutical laboratory
laboratories, then the EU requirements must be verified. In other
laboratories, a calibration certificate is usually sufficient for
laboratory balances.
