Batch documentation
Review documentation for the product and variant you are purchasing. A reference specification, a research publication and an individual batch certificate are different sources. Ask support which documents are available for your chosen variant and batch. No analytical result should be assumed from a catalog specification.
Consult batch certificates How to read documentationLaboratory handling
- Reconstitution
- Laboratory procedure: allow the closed vial to reach room temperature, disinfect the septum and slowly transfer the diluent against the inner wall of the vial. Do not shake; gently swirl the vial until fully dissolved. Record the volume, diluent and date in the batch log.
- Storage
- Sealed vial of lyophilized material: store at −20 °C, protected from light and moisture. Avoid repeated freeze-thaw cycles of reconstituted material; aliquot when the experimental design permits.
- Protective equipment
- Handle in a clean work area with a lab coat, nitrile gloves and eye protection. Dispose of vials, tips and sharps according to the laboratory waste procedure.
