Question

An adjustable pipette delivers 0.996 (±0.001) mL when set to 1.000 mL. The manufacturer’s tolerances for this pipette at this volume are ±0.3% accuracy and ±0.12% precision. Is this pipette operating within specifications?

Answer 1

LBG N is a neutral borosilicate glass with a high chemical resistance. Its average linear dilation coefficient is 8.0•10-6 K-1. It is used in products not intended to be directly heated, but instead should have a higher mechanical resistance (such as mortars, desiccators, filtering flasks …) or in some volumetric glassware (such as pipettes, burettes …). LBG A is a neutral borosilicate glass similar to LBG N but amber so to protect photosensitive products.

In some volumetric glassware (such as pipettes, burettes …). LBG A is sales unit reference capacity accuracy. (ml) stopper pcs per sales unit per sales unit.The manufacturer’s tolerances for this pipette at this volume are ±0.3% accuracy and ±0.12% precision.

YES. Pipettes used within specifications
