Analytical Balance 2. OBJECTIVE To lay down a procedure for operating and cleaning of analytical balance) SCOPE This SOP shall provide the Operating procedure of analytical balance of quality control department. Analytical Scale Calibration using a set of standard weights. The word 'balance' arose from the Greek word 'bilanx' meaning 'two-pans.' Analytical balances are designed for very precise measurements of very small samples. Location free from air should not be near … Strategies are presented to minimize errors associated with evaporation or other sample losses that might occur … according to the National Institute of Health (NIH). They yield readability to four decimal places to the right of the decimal point (up to … Refer to "3. Objective: define the meaning and how to use properly the analytical balance. These systems distinguish themselves from conventional balance cells in terms of both … Some of them are analytical balances . • These units’ measuring pans are usually encased in a glass box so as to prevent any … Analytical balances have finer readability, are much more sensitive to changes, and can detect smaller variations in mass. 3. Balance should be placed on a solid, stable, plain flat surface 3. A draft shield is provided to prevent inaccurate readings. 2. A precision balance and a magnetic stirrer in one unit, with a capacity of up to 4200 g and a readability of 0,01 g. With the integrated magnetic stirrer, up to 3 … Drift check . Doesn't locate AVT corner of the room-room access through a sliding door. This procedure is applicable to Mettler analytical balances of Quality Control (QC) installed in Microbiology Laboratory. Analytical balance 1. A standard analytical balance typically has a maximum capacity of 160–300g and a readability of 0.1mg. When analytical balances are used in routine lab or industrial measure-ment environments, the weighing speed will be much quicker, and the results more accurate. 2-2.
