一般描述

Volumetric flasks are available in two different accuracy Classes: Class A and Class B. The two Classes differ in the accuracy of measurement with Class A being the highest accuracy, and Class B is approximately half that of Class A. The volumetric flasks with accuracy Class A have a blue print for clear glass products and a white print for amber versions. Volumetric flasks with a batch number and accuracy Class A are supplied with a batch certificate. This certificate documents the mean value obtained from measuring the batch in question, the standard deviation and the day of issue. The batch certificates can also be retrieved online. The batch number consists of four digits. The first two numbers specify the production year, and the following two numbers specify the batch, e.g.: 18.01.

应用

precise measurement of specified liquid amounts, preparation and storage of standard solutions

特点和优势

  • Complies with ISO 1042
  • Made from borosilicate glass 3.3
  • With batch certificate
  • Outstanding precision during volumetric measurement and high-quality process stability
  • Thanks to the exact processing and precisely calibrated scales, they permit the highly accurate determination and measurements of volume
  • Calibration based on the poured in volume (“In”) at a + 20 °C reference temperature
  • The volume content tolerances conform to accuracy Class A
  • Supplied with octagonal polyethylene stopper
  • With scratched graduation mark and white print image
