Semi Micro Balances

A semi micro balance is typically used in a laboratory or scientific setting where precise measurements of small samples matter and are required for research, quality control, and compliance. Typical uses of semi micro balances include sample and standard preparation, formulation, and filter weighing.

The weighing principle of METTLER TOLEDO semi micro balances is based on electromagnetic force compensation. The weighing cell inside the balance housing creates a counteracting electromagnetic force to the object that has been placed on the weighing pan. The semi micro balance interprets the magnitude of this compensating electromagnetic force as the weight of the object. The result is displayed on the balance terminal in the appropriate unit.

The weighing pan of a semi micro balance is placed inside a draft shield, which protects the sample and container from external environmental influences like air drafts, improving general weighing performance. This is particularly important when the accuracy of results is of the utmost importance.

The main difference between semi-micro scales and micro balances lies in their sensitivity and capacity. Micro balances are more sensitive, capable of measuring very small weights (down to 0.1 µg), while semi-micro scales are suitable for slightly larger sample weights and provide a balance of accuracy and convenience for routine laboratory tasks.
