HPLC columns, Purospher® STAR RP-18 endcapped

Supplier: Merck

Fast method development of complex samples across the pH range from 1,5 to 10,5 with different mobile phases and temperature conditions.
Purospher® STAR RP-18 endcapped HPLC columns are designed for universal use. Basic, neutral and metal-chelating compounds can easily be separated with simple mobile phases – naturally without peak tailing. Thanks to its outstanding performance and stability, Purospher® STAR RP-18 endcapped offers maximum flexibility in method development. Robust methods can be developed over the entire pH range from 1,5 to 10,5. High pH-stability allows the separation of strongly basic compounds with alkaline eluents. The combination of high purity silica, best all-round retention characteristics, outstanding pH stability up to pH 10,5, and suitability for up to 100% aqueous mobile phases, make Purospher® STAR RP-18 endcapped an all-round top performance column, almost universal in its range of applications.

Vacuum drying chambers, VD and VDL series

Supplier: Binder

The VD series of vacuum drying chambers provide fast gentle drying of non flammable solvents, delivering impressive performance through their precise temperature control and gentle drying. Expansion rack technology also ensures optimal heat transfer, shelves provide flexible placement, and the interior of the chamber is easy to clean. The VDL series of safety vacuum drying chambers ensures maximum safety when drying flammable organic solvents, and have been safety tested by a state recognised test institute (GS mark). VD/VDL units can also be purchased as modular options with vacuum pump and pump chamber to form a complete system.
