Why dairies choose it

At the ramp, before the hose is connected

One treated cow can cost you the whole tanker

A strip test at intake answers in minutes, before the milk is pumped into the silo and blended with clean milk. Calibrated to the EU limits, so compliant milk is not rejected.

What is in the box

Everything for 96 tests

96 test strips, 96 reagent microwells and a 200 µl pipette with tips. You only add the milk.

Result in 6 minutes

Put the strip in the well and the lines appear while you wait. No laboratory, no special training.

Read by eye in seconds

The control line must appear. A test line as faint as the control, or missing, is positive. No reader needed.

Made for the intake point, not the laboratory

Runs on the ramp, in the truck or on the farm. The 40 °C format is the fastest and most sensitive; the room-temperature format needs no equipment at all.

  • 200 µl of milk, no preparation
  • 3 + 3 minutes at 40 °C in the M1005 incubator, or 5 + 5 at room temperature
  • Same reading rule across the whole Ringbio range, one training covers all kits

Questions dairies ask

Will the test reject milk that is legally compliant?

No. The articles we supply are calibrated to the EU maximum residue limits: they turn positive below the limit but not at trace levels.

What do I do with a positive result?

Hold the delivery, keep a retained sample and confirm in an accredited laboratory before raising a claim with the supplier.

Do I need an incubator?

Only for the 40 °C kits. Room-temperature kits need nothing but a pipette and a timer. In a cold intake bay the M1005 keeps either format at its optimum.

Can I use it on sheep or goat milk?

The standard kits are validated on raw cow’s milk; Ringbio has a dedicated goat-milk range, ask us.
