If you have ever questioned the result of an analytical test, you'll immediately appreciate the value of using standard solutions. These solutions contain a defined concentration of analyte, allowing you to quickly verify that instrument operation, reagent performance, and variations in operator…

100 ng/μL in acetonitrile, PESTANAL ® , analytical standard Synonym(s): (4'' R )-4"-(Acetylamino)-4"-deoxy-avermectin B₁ solution MDL Number: MFCD07370747 Storage: 2-8°C RIDADR: UN 1648 3 / PGII

This pH optimized saturated salt solution is designed to keep your electrodes in good health. pH electrodes must not be stored in deionised water and should be kept in an appropriate storage solution between uses to avoid drying out which will reduce response speed and may cause them to fail.…
