If you are concerned about antibiotic residue using the SNAP Beta-Lactam ST Plus Test will give you the reassurance of product quality with the most thorough rapid test available. These rapid tests can be read in 6-8 minutes. The ST Plus has unmatched residue detection. It detects more beta-lactam residues, including cephalexin, than any rapid dairy test. A test can be done on:

  • Raw milk
  • UHT milk
  • Sterilized milk
  • Reconstituted milk powder
  • Thawed milk
  • and Skimmed milk.

Species include:

  • Cows

Rugged and versatile, you can test raw or commingled milk on the go, without heat or incubation. Farmers, truck drivers, and laboratories can read robust test results visually, or by using the SNAPshot DSR Reader. Backed by IDEXX. Process milk with confidence knowing that IDEXX's rigorous quality control standards include ISO 9001:2008 certification and independent validation by ILVO (Institute of Agricultural and Fisheries Research).
