A balance is an essential as well as primary piece of equipment for any laboratory. The first as well as leading consideration in shopping for a Laboratory Balance is simplicity of thought on use and application. The idea of the balance, the type of materials as well as the amount of materials entire factor into the choice of instrument. For solid, inert materials of a kilogram or more, an industrial balance would be the accurate choice. For calculating microgram quantities of pharmaceutical compounds, a precision Analytical Balance would be necessary.

Similarly, believe the laboratory and the overall environment. For a dusty environment like a factory floor, search for balances that are sealed against outside materials. If there are temperature fluctuations, vibrations, or a sensitive analytic balance might not function well. Some balances come with their own enclosures to stay contaminants out.

Analytical Balance

Most life science laboratories need an analytical balance for exactness weighing. Analytical balances should only be used by trained personnel as well as require regular calibration and maintenance. Because of this, they are generally set up in a separate, interior room of the laboratory, out of the way of general foot traffic, flying objects, chemical spills, vibrations as well as other disturbances. Additionally, locking the room may keep well-intentioned however untrained visitors from utilizing them.

For very sensitive balances, an antistatic mat will assist to improve accuracy. Some analytical scales have a feature that ensures automatic recalibration at specific intervals or under certain circumstances, such as temperature fluctuation. Other balances should be calibrated by hand. Calibration may be inside motor-driven, or external.

While a balance require not be set up in a clean room, it should not be subjected to dusty as well as dirty environments. While dust cannot be avoided, the user should look for a scale with an ingress protection (IP) rating. Scales with high IP numbers are resistant to particulate as well as liquid contaminants. The two-digit rating offers the resistance of the scale to solid as well as liquid matter, respectively.

Analytical balances are developed for high precision in quantitative chemical analysis. They yield readability to four decimal places to the accurate of the decimal point (up to .0001 g). They are extremely sensitive and, since air currents can affect their measurement should be covered by a draft shield. They are utilized for samples up to about 320 g. Top-loading balances, which may easily  measure objects up to 200 g, are less expensive but less exacting than analytical balances.

 They are known semi-analytical balances, with a readability of up to three decimal places to the right of the decimal point (up to .001 g). Precision balances have a readability of 0.01 g. They produce stable readings in a wider range of environmental conditions than analytical balances, being less sensitive to temperature fluctuations. They may have a capacity from 600 g to 34,000 g.

Weighing abilities of an analytical balance range from tens or hundreds of grams to as low as 0.1 or 0.01 mg. Practical features include a clock, piece counting, mass unit conversion as well as data record-keeping.
