- For suitable glass stoppers, see section laboratory glass.
|
- Calibration is based on the poured in volume (“In”) at a + 20 °C reference temperature. The volume content tolerances conform to accuracy class A, the accuracy limits of the German weights and measures regulations and DIN and ISO specifications.
|
- Typical applications: precise measurement of specified liquid amounts, preparation and storage of standard solutions.
|
- DURAN® volumetric products have closely calibrated scales that permit very accurate determination and measurement of volumes. DURAN® products are available in two accuracy classes: class A/AS and class B. The two classes differ in the accuracy of measurement with class A being the highest accuracy class and class B being approximately half that of class A. Class AS has the same tolerances as class A, but is designed to permit more rapid outflow.
|
- To ensure a long service life for your volumetric glassware and to exclude possible volume changes, these products should not be heated above +180 °C in drying cabinets or sterilisers.
|
- Never heat volumetric glassware on a hot plate.
|
- Always heat up and cool down volumetric glassware gradually, to avoid thermal stresses and thus any possible breakage of the glass.
