High-performance liquid chromatography assesses compound purity and helps verify the stated 99%+ purity specification for research batches.
PURITY ANALYSISLiquid chromatography-mass spectrometry provides analytical evidence of compound identity by examining chemical characteristics and molecular mass.
IDENTITY VERIFICATIONResearch batches are checked for bacterial endotoxins against defined specifications, with results documented in the relevant laboratory reports.
BATCH SCREENINGEvery order is stated to include a batch-specific CoA so researchers can review the reported identity and purity results for their materials.
Peptides can be sensitive to environmental conditions. Appropriate storage and shipping help protect material stability during transport.
Our stated process uses freezer storage and temperature-monitored insulated packaging, helping protect research materials from dispatch through delivery.
Research materials are stored under controlled conditions before packing.
Insulated packaging and appropriate cooling materials help manage transit temperatures.
Orders are dispatched using the stated cold-chain shipping process across the UK.
