Maintenance & Buyer’s Tips

Proper handling and storage preserve the separation efficiency of silica gel chromatography plates. Follow these guidelines to achieve optimal analytical results and ensure product authenticity.

• Storage Environment: Store unopened packs in a cool, dry area away from volatile organic vapors. Moisture absorption alters retention factors.

• Pre-Activation Procedure: Heat plates at 110°C for 20 minutes prior to delicate separations to remove absorbed atmospheric moisture.

• Handling Protocols: Always hold plates by the edges or use clean forceps. Direct skin contact transfers oils that distort baseline chromatography runs.

• Verifying Authenticity: Ensure the package features original Macherey-Nagel branding, sealed batch labels, and intact security stickers. Buy directly from a verified industrial testing equipment importer to avoid counterfeit laboratory consumables.
