What they are

Individually sealed pads saturated with 70% isopropyl alcohol, the concentration that disinfects most effectively (higher concentrations evaporate before they act). Pack of 100. Used to clean the rubber stopper of a vial before each puncture and the surface you are working on.

Alcohol swabs (also sold as alcohol prep pads or IPA swabs) are a laboratory basic; ours are stocked in the UK and ship with any order.

Why 70% and not 99%

Water is needed for the alcohol to penetrate microbial cell walls; 70% is the balance between disinfecting action and evaporation time. Pure IPA flashes off too fast to be effective.

In the laboratory

One swab per stopper per puncture, allowed to air-dry for a few seconds before the needle goes in. Also suitable for wiping down the work surface and the outside of syringes.

Alcohol Prep Swabs price (UK)

Prices include VAT. Shipping is £4.95 by Royal Mail Tracked 48, free on orders over £75, and sealed items can be returned within 14 days. Ships from UK stock with the lot certificate for the vial you receive.

Quality and testing

Every lot of Alcohol Prep Swabs is released with its certificate of analysis published on our certificates page against the lot number on the vial label. The certificate for the current lot is pending publication, and ALTA's own independent third-party test of the lot is pending; both are added to the certificates page as they arrive. Specification: Sterile, individually sealed, supplied as pack of 100.

Lot traceability

Every Alcohol Prep Swabs vial carries a printed lot number and expiry. The same lot number appears on the certificate of analysis for that lot on our certificates page, which names who issued it (the manufacturer's QC laboratory for a batch certificate, or the outside laboratory for a third-party report) so it can be checked directly. ALTA's own independent test of each lot is published on the same row as it arrives. If the number on your vial does not match a certificate on our site, contact support before using it. Certificates are kept online for the life of the product plus two years.

Handling and storage

Room temperature. Keep sealed until use. Allow the vial to reach room temperature before opening to avoid condensation on the powder. Reconstitute with bacteriostatic water added slowly down the wall of the vial; do not shake. Our calculator covers the arithmetic.
