Dissolving strips for research
Thin polymer films carrying a measured load of active, designed to disintegrate on contact with moisture. The format removes reconstitution and measurement from the workflow entirely — and fixes the quantity per strip, which is the reason it suits some designs and not others.

What is a dissolving film?
A thin, flexible polymer strip loaded with an active compound, engineered to disintegrate rapidly on contact with moisture. The polymer matrix holds the load evenly so each strip carries the same nominal content.
When is a strip the wrong format?
Whenever you need a concentration series. The quantity per strip is fixed at manufacture, so a dose-response design is far better served by a vial, a diluent and a syringe. Strips suit fixed-quantity work where consistency between units matters more than adjustability.
How should film strips be stored?
Sealed, dry and at room temperature. Films are hygroscopic by design — that responsiveness to moisture is what makes them dissolve — so a pack left open will absorb atmospheric water. A strip that feels tacky has already done so.
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 dissolving strips, 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 dissolving strips
How many strips are in a pack?
Thirty for the single-compound packs and twenty for the combined Selank and Semax strip. Each product page states the count.
Are the strips tested like the vials?
No. The vials carry a lot-matched certificate from an independent US laboratory. The strips do not, and their product pages say so rather than implying a document that does not exist.
Are these for human use?
No. Sold for in-vitro laboratory research only.
Every product in this category is sold for in-vitro laboratory research only and is not for human or animal consumption, diagnostic or therapeutic use.
