Novel Corona Virus (SARS-CoV-2) Ag Rapid Test Kit
Antigen rapid tests are bought by test count, but buffer, swab and control components decide how a bench runs. Three pack sizes scale those components together.
Rapid antigen screening is consumable-driven: each test uses a cassette, swab, dropper, extraction tube and a share of extraction buffer. Buyers read these kits by contents as much as by catalogue number.
The Bioperfectus kit appears under three catalogue numbers — SC30107W-20T, SC30107W-25T and SC30107W-50T — for 20, 25 and 50 tests per kit. Cassettes, swabs, droppers and sample extraction tubes are supplied in matching counts.
Extraction buffer is the exception: the 20-test and 25-test kits each carry 7.5 mL × 2 tubes, while the 50-test kit carries 7.5 mL × 4 tubes.
Each kit also includes one instruction for use, one operation card, and positive and negative control tubes with pipettes.
The manufacturer states the kit is for trained personnel, used under applicable instructions, laboratory procedures and local regulatory requirements. The supplied material carries no sensitivity, specificity, shelf-life or approval claims.
That gap shapes procurement. Buyers should confirm regulatory status in their market, storage conditions, expiry dating, minimum order quantity and delivery terms, and whether a 20-test or 25-test format suits lower-throughput sites better than the 50-test pack.
The difference between these SKUs is packaging arithmetic rather than chemistry. Matching pack size to realistic test volume limits both stockouts and expired buffer.
Why it matters:
Configuration, not headline price, determines cost per test and waste. Verify documentation and regulatory standing before choosing a pack size.
