Sterile Empty Vials
Sterile, sealed empty glass vials for aliquoting and storing reconstituted peptides
Supplied for laboratory research use only. Not for human or veterinary use, and not intended to diagnose, treat, cure or prevent any disease.
Overview
In peptide research the most common use is aliquoting: once a lyophilized vial has been reconstituted, dividing the stock into several smaller vials means each aliquot is punctured fewer times, reduces the risk of contaminating the whole batch, and allows portions to be refrigerated or frozen separately. Empty vials are also used to prepare working dilutions at lower concentration, to combine components for a blend study, or simply to hold a measured volume of bacteriostatic water for a single experiment.

Questions about Sterile Empty Vials
What are sterile empty vials used for in peptide research?
Mainly for aliquoting: dividing a freshly reconstituted peptide vial into smaller sealed portions so each is punctured less often and can be refrigerated or frozen separately. They are also used to prepare working dilutions, to combine components for blend studies, and to hold measured volumes of diluent for a single experiment.
Which size should I choose?
The 3 mL vial handles aliquots up to roughly 2 mL and matches the size of most peptide vials in our catalog. The 10 mL vial is for larger working solutions, dilution series or holding a portion of bacteriostatic water. Both come ten to a pack.
Can the vials be frozen?
Yes. Borosilicate glass and the rubber stopper tolerate −20 °C storage. Leave adequate headspace because aqueous solutions expand when they freeze, and let vials warm to room temperature before entering the stopper so condensation does not enter the needle track.
Are the vials sterile and documented?
The vials are sterilized and sealed before shipment and remain sterile inside until the flip-off cap is removed. Lot information is on the packaging and available on request. As empty containers, HPLC purity does not apply; they contain no peptide or diluent.
