Types of Analytical Balances and their uses in Laboratories

An analytical balance is used to measure the mass of a given object with high level of accuracy and great precision. The precision of analytical balance is not affected by changes in gravity. The balance shoes the same weight even if the strength of gravity is changed. This feature enables the scientists to get accurate measurements of the samples at anytime without any fluctuations in readings.

An analytical balance has a separate enclosure where the pans are placed. The transparent shielding helps to keep away the dust from the pans and also to minimize the effects of air flow on the samples. The separate weighing enclosure has air foils to regulate the airflow and helps to get the readings of delicate and small samples without any loss due to air.

There are a large number of weighing balances available in the market. These balances are designed to meet the requirements of various industries. Some examples of commonly used balances are top-loading balances, micro balances, beam balances, analytical balances, spring balances and precision scales. The features vary from one model to another and the users should buy a balance that is most suitable for the laboratory setting and the types of readings needed. For example, micro balances and ultra micro balances are suitable for research laboratories which want accurate measurement of microscopic samples. These balances provide reading up to seven decimal places and have a capacity of 6 grams.

The cost of the balance depends upon the features and precision offered by each model. For example, a top loading balance is not expensive, but it is suitable for use only in those areas which do not require absolute measurements. This type of balance has a readability of only three decimal places and is considered as a semi analytical balance. On the other hand, a spring balance has readability of two decimal places but provides a steady reading of the samples, irrespective of changes in environmental factors.

The precision of an analytical balance is affected by a number of reasons like the operating temperature of the lab, the air flow and humidity present in the lab, the vibration and ventilation currents generated in the lab and the overall environment of the lab. It is always advisable to keep the balance in a separate enclosure and place it properly leveled.

Proper maintenance of analytical balance is very important for efficient functioning. Regular servicing by experienced technicians is also required to keep these balances functioning accurately. The staff handling these balances should be adequately trained and follow the instructions provided in the manual properly.
