The regulation “EUROPEAN PHARMACOPOEIA 3.2.1. Glass Containers for pharmaceutical use” mandates the requirements for medical glass containers and defines its properties. One criterion for testing is the determination of the hydrolytic class according to „DIN ISO 719“. Here glass powder with a particle size

Selecting chromatography vials for lab use is complicated because there are many glass vials are made from 51 expansion glass (heated at 1,00°C during Chromatography - Focus on vials, closures & chemicals. Firstly, almost all vials are made out of 1st hydrolytic class glass. 1, Class B), whereas amber is generally only available as 51 ...

Clear Glass of 1st hydrolytic class is differentiated by 33 expansion (Type 1, Class A) and 51 expansion glass (Type 1, Class B), whereas amber is generally worldwide only available as 51 expansion glass. The indicated lower expansion coefficient of 33 implies that this harder clear glass has to be processed at higher temperatures. These amount

Mar 30, 2012 · Clear glass of first hydrolytic class is divided into two categories: “33 expansion” (Type 1, Class A) and “51 expansion” glass (Type 1, Class B). The indicated lower expansion coefficient of 33 implies that this harder clear glass has to be processed at higher temperatures when manufacturing auto sampler vials.

Chromatography Sizes. Vials come in a variety of sizes to suit many needs. Standard sizes include 12x32mm (2mL), 15x45mm (4mL) and 8x40mm (1mL). Users may also choose vials with a normal (4 mm) mouth opening or wide (6 mm) mouth opening depending upon the cap type to be chosen. Important also is whether your sample is handled via Robotic Arm
