Supplier: VWR Chemicals

For spectrophotometer calibration according to European Pharmacopoeia (Ph. Eur.)

Supplier: VWR Chemicals

These solutions are developed and produced according to chapter 2.2.2. 'Degree of colouration of liquids' of the European Pharmacopoeia. (brown, brown-yellow, green-yellow, red and yellow). These kits are ready to use, and are dedicated to help you save time and money because preparation of these solutions is very complex.

Supplier: Merck

The fluid sampling kit is a complete solution for field-based fluid collection and contamination analysis. The stainless steel sampler assembly plugs into a quick-release valve installed in the system line, which allows a measured quantity of liquid to pass through the monitor. A valved syringe serves as a pump to remove residual liquid from the monitor. Kit is compatible with our 37 mm contamination monitors and matched-weight monitors.
