Explore the Precision Balances & Scales
Precision balances and scales also know as toploader & milligram balances are used to weigh medium to large sample amounts into vessels or containers or for other applications that require a weighing capacity up to the kg range.
Model Design
Precision balances with a readability of 1 mg (milligram balance) are usually equipped with a manual or automatic working three-door glass draft shield and a weighing pan size from Ø115 mm up to 140x140 mm.
Balances with a readability of 10 mg up to 1 g, called precision or toploader balances, most are featured with a weighing pan without a draft shield. The weighing pan is made out of stainless steel and comes in a size is between Ø180 mm and 206x206 mm.
Analytical Balance vs Precision Balance
An analytical balance is more accurate than a precision balance. An analytical balance comes with a readability of 0.1 mg or 0.0001 g, whereas a precision balance typically has readability of ≥1 mg or ≥0.001 g. So an analytical balance has at least a 10-times higher readability compared to a precision balance.

Frequently asked questions for lab balance
Sartorius recommend to perform a three-point calibration for daily check. One weight at >80% of maximum capacity, one weight at the minimum weight and finally one weight where typical sample size frequently weighed-out on the balance in question.
Best to have it set on automatic, this way the balance will always be adjusted to the environment in which it is located. It is acceptable that when you are about to use the balance and you feel it may have not adjusted in a while, to initial a manual internal adjustment.
Ensure the balance is on a stable base. Best to have a level Indicator which displays on the screen. Ideally, have automatic, motorized one touch levelling or built-in real-time level support. Also, if possible, have automatic doors on the draft shield. Gesture sensor for touch-free operation is highly recommended to assist with the ergonomic workflow in a restricted area.
isoCAL is launched when conditions change or, depending on the balance readability, on a timed interval. For 4-, 5-, 6- and 7-digit balances it is every four hours. For lower resolution balances it is every six hours.
