Psychrofast Test Kit
Rapid psychrotroph test for dairy
Psychrofast detects gram-negative psychrotrophic bacteria in pasteurised milk and dairy products within 30 hours. This simple presence/absence test uses selective enrichment, inhibiting gram-positive bacteria and showing growth with a visual indicator, with no diagnostic machines required.

| Format | Presence/absence |
| Pack size | 100 or 200 tests |
Benefits
- Results within 30 hours: Instead of up to 10 days (or 4 days with modified methods).
- Finds what standard tests miss: Aerobic plate counts and coliform tests don't detect psychrotrophs.
- No diagnostics machines required: A clear pink colour shows a positive.
- Straightforward to use: Practical for routine quality control.
- Protects shelf life: Catch spoilage organisms before products fail before their use-by date.
Features
Why pick Psychrofast?
Psychrotrophic bacteria thrive at refrigeration temperatures and are a primary cause of premature spoilage in pasteurised milk. Conventional methods miss them: aerobic plate counts mainly count mesophilic bacteria, and coliform tests target enteric species. So products can spoil before their use-by date even when standard tests show low counts and no coliforms. Existing dedicated psychrotroph methods need up to 10 days of incubation (or 4 days with modified protocols), which is impractical for routine QC.
Procedure
Psychrofast uses selective enrichment technology, combining targeted inhibition of gram-positive bacteria with a visual growth indicator.
Results
The presence of gram-negative psychrotrophs is shown by a pink colour in the tube (see the image on the right).
