Burettes PTFE Key Stopcock Class A - Schellbach Stripe

Burettes PTFE Key Stopcock Class A - Schellbach Stripe

The original burettes are made of highly chemically resistant borosilicate glass 3.3. Their precise scaling makes them particularly suitable for titrimetric purposes aided by the Schellbach stripe for accurate menscus reading. Adjustment is made to drain ("Ex") for + 20 °C reference temperature. This means that the quantities can be taken exactly according to the scale, since the adhesion of the liquid to the glass was taken into account during calibration. The tolerances for the volume correspond to the error limits of ISO.

• Compliance with DIN ISO 385 and USP standard.
• With Batch Certificate.
• Printed in blue colour.
• Highly resistant to chemical attack.
