Single vials

A single vial is the standard unit for laboratory work: one sealed 2 ml borosilicate glass vial containing the stated fill of lyophilised peptide, with a crimped cap and a label carrying the compound name, fill, catalogue reference and lot number.

Because the offer is buy one, get one free, every single-vial order ships as a pair. One vial can be opened for immediate work while the second stays sealed at -20°C, which is how most laboratories prefer to hold stock.

Fills range from 5 mg to 50 mg depending on the compound. Where a compound is available in more than one strength, the product page shows every strength side by side with the price per milligram, so it is simple to compare.

All single vials are covered by the same testing protocol: HPLC purity and mass-spectrometry identity on every batch, reported on a Janoshik certificate that can be verified online.

Research use only. Not for human or veterinary use.
