Peptide liquid sprays and metered research solutions
Pre-dissolved research solutions in a 10 mL metered atomiser, supplied ready to use rather than as a lyophilized powder. The trade is convenience against control: the concentration is fixed at fill, and a solution is subject to degradation from the day it is made in a way a sealed dry vial is not.

Why choose a solution over a lyophilized vial?
Because it removes reconstitution from the workflow. There is no diluent to source, no volume to calculate and no chance of a reconstitution error. What you give up is the ability to choose your own concentration, and the long-term stability of the dry state.
How stable is a peptide in a ready-made solution?
Less stable than the same peptide as a powder, by a wide margin. Deamidation, oxidation and hydrolysis all need water, and in a filled atomiser the water is already there. Refrigerate, protect from light, and treat the stated window seriously — the solution-stability post covers the chemistry.
What does 'per actuation' mean?
The nominal quantity delivered by one press of the metered pump. It is a design figure for the device, not a measured value for your particular bottle, so where accuracy matters you should verify the delivered volume gravimetrically rather than assume it.
Why is there no certificate for these?
The certificate library holds reports for lyophilized lots: a laboratory takes a sample of the dry powder and measures identity, purity, content and endotoxin on it. The products in this category are liquid sprays, not lyophilized vials, so they are not represented there. For a lot report on a solution, strip or supply, email support with the lot printed on the pack and we will send the one that matches it.
If you are comparing formats, the practical point is that a weighed amount from a lyophilized vial is what a quantitative assay starts from: a measured mass dissolved to a known concentration, as the concentration table sets out. A metered solution or a film strip delivers a nominal amount per actuation or per unit, which is a different kind of number.
Common questions about liquid sprays
Do the sprays come with a certificate?
No. The vial lots are tested by an independent US laboratory and their certificates are published in the COA library; the sprays are not covered by those documents and have no certificate of their own. Each spray page says so in place of a figure.
Can I refrigerate a spray?
You should. 2-8°C and protection from light is the storage condition for every solution in this category.
Are these for human use?
No. Everything in this category is sold for in-vitro laboratory research only and is not for human or animal consumption.
