Welch Materials offers Welchrom ® Sample vials of Type 1, 51-expansion glass vials and Type-2, 33-expansion glass vials. Welchrom ® Sample vials are made from first class of hydrolytic borosilicate glass, compliant with the requirements of U.S. and European Pharmacopeia, which improve your laboratory productivity by reducing costs and saving time. These products considerably reduce the risk of analytical test compromise resulted from ghost peaks, damaged needles, dislodged septa

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. Approximately 1,200°C is required for “33 expansion” glass in comparison to only approximately 1,000°C for “51 expansion” glass. From a quality point of view, both

1st hydrolytic class glass 51 expansion meets all current USP and Pharmacopeia criteria; Short thread screw vials and caps: convenient handling of mid volatiles; Crimp vials and caps: for low evaporation of highly volatile samples; Snap vials and caps: convenient handling of low volatile samples; Amber vials ensure integrity for light sensitive samples

8 LABSOLUTE® VIALS & CAPS SCREW NECK ND8 SCREW NECK VIALS AND MICRO-VIALS ND8 Screw neck vials and micro-vials ND8 are used as standard in GC and HPLC. A large selection of micro-inserts is available for these vials. The micro-vials often require an adapter so that they can be used in the autosampler. Properties • 1st hydrolytic class glass

The vials are made from 1st hydrolytic class 51 expansion glass. The vast range of vials includes micro and fused inserts, standard 2ml autosampler and larger sample storage, headspace and EPA vials. EPA Vials & Caps HPLC & GC Autosampler Vials HPLC & GC Caps Inserts Kit packs with vial, assembled cap and septa Sample Storage & Collection

The vials are made from 1st hydrolytic class 51 expansion glass which, unlike inferior alternatives, allows the manufacturing of clean, precision-fit vials. Our comprehensive range of vials includes micro and fused inserts, standard 2 mL autosampler and larger sample storage, glass sample vials with screw caps, headspace vials, and EPA vials.

autosampler glass vials from different sources. In this case 1st hydrolytic class tubes have been used with examples of 33, 51 and 70 expansion type raw glass tubes. • 1 mL 18MΩ HPLC water (Aijiren Tech™ Smart2Pure™ system (P/N 50129845)) was added to the 2 mL vial and capped using Aijiren Tech™

All vials are made from 1 st hydrolytic class 51 expansion glass, the physical properties of which allow the manufacturing of clean, precision fit vials. Vials manufactured with alternative expansion glass can lead to inferior quality with wider tolerances, adding extractables to the analysis and causing failures, particularly during overnight

Glass Type All vials are made from 1 st hydrolytic class 51 expansion glass. The physical properties allow the manufacturing of clean, precision fit vials. Vials manufactured with alternative expansion glass lead to inferior quality with greater tolerances and extractables.

What are the differences between “33 expansion”

Clear Glass of 1st hydrolytic class is differentiated by 33 expan-sion (Type 1, Class A) and 51 expansion glass (Type 1, Class B), whereas amber is generally worldwide only available as 51 expan-sion glass. The indicated lower expansion coefficient of 33 implies that this harder clear glass has to be processed at higher tempera-tures. These amount to approx. 1,200°C for 33 expansion glass in comparison to only approx. 1,000°C for glass of 51 expansion.
