Cahn 1000 mg (1g) Microbalance Calibration Weight - Used

Used 1000 mg calibration weight for Cahn balances- barrel shaped.

This is the correct calibration weight to use on the "B" scale (and "B" hangdown) on many Cahn micro and ultra- microbalances.

If calibrating on the "A" scale, use a 200 mg calibration weight.
