Laboratory balances, from economy to expensive analytical models, require routine calibration and accuracy confirmation. Precision, compact, and portable balances (readability 0.1 to 0.001g) can be calibrated with the class F1 calibration set. Included in the set are 23 stainless steel cylindrical and leaf weights: 2 x 200g, 1 x 100g, 1 x 50g, 2 x 20g, 1 x 10g, 1 x 5g, 2 x 2g, 1 x 1g, 1 x 500mg, 2 x 200mg, 1 x 100mg, 1 x 50mg, 2 x 20mg, 1 x 10mg, 1 x 5mg, 2 x 2mg, 1 x 1mg. Cylindrical weights are marked with their nominal value. All are supplied in a protective case along with tweezers, a cleaning cloth and dust brush.
