About the dairy dipslides (box of 10)

Our bacteria testing dairy dipslides will measure levels of viable micro-organisms in dairy products. Low bacteria levels in general will need to be maintained and bacteria counts should adhere to legal levels. In the USA, the maximum allowed for total bacteria counts for pasteurised milk is 20,000/ml (as stated on the FDA website).

If your dairy sample contains microbiological contaminants, colonies will grow on the dipslide agars. You can count these colonies and compare with the chart provided to assess the level of contamination.

Dairy products that are frequently tested for contamination:

  • raw milk (primarily USA)
  • pasteurised milk (some bacteria can survive pasteurisation)
  • sour cream
  • yoghurt
  • cheeses
  • butters
  • ice creams.

There are two options for dairy testing dipslides: PC2 and PC2T. Both offer total count on both sides with PC2T slides having the additional Red Spot Dye. Plate count agar (on both slides) is the recommended agar for testing bacteria / micro-organisms in dairy products and food in general. These slides will determine the number of aerobic bacteria in the samples that you test.

The red spot dye in the PC2T slides is an addition that shows the results as red dots making it easier to decipher any colonies that appear on the slide after incubation. Either slide is ideal for testing dairy and aside from the red spot dye, are exactly the same. Whichever the user chooses is down to personal preference.

This listing is for the PC2 slide, if you prefer to purchase the slide with the Red Spot Dye, you can do here:

PC2T Dipslides

This product listing price is for a box of 10 slides.

How to use Dairy Dipslides

With products such as butter and yoghurt (higher viscosity), swabbing the sample on to the slide would be preferable to dipping.

  1. Remove the dipslide from its container and either immerse the slide in to a fluid sample or swab a sample onto both sides of the slide.
  2. If you tested a fluid sample, allow to drain. Replace slide into container and replace cap.
  3. Incubate slide for 24 - 48 hours. Once incubated, compare the results to the chart provided.
Remove Dairy slide from tube

Step 1 : Remove slide

Carefully remove the sterile Dairy dip slide from its tube ensuring that no contact is made with the agar (to avoid contamination).

Surface testing

Step 2 : If Surface Testing

For surface testing, press the Dairy dipslide onto the surface. If needed, place a finger on the bottom of the slide (on the plastic, not the agar) to apply extra pressure.

Liquid Testing

Step 2 : If liquid testing

For liquid testing, immerse the Dairy dipslide into the fluid for 10 seconds then remove and allow to drain for a few seconds.

Swab Testing

Step 2 : If swab testing

Apply a sample of the test substance to a sterile swab and gently apply to the agars.

Incubate the dipslide

Step 3 : Incubate Slide

Label the tube with the included stickers then place the slide into an incubator and allow to incubate.

compare dipslide results

Step 4 : Compare results

Count the amount of colonies that have grown on the slide and compare them to the comparison chart provided.

You will require an incubator to interpret your results correctly. You can find our range of incubators in our incubator section.

Dairy Dipslide Features

Flexible paddle

Each slide has a handle built into the lid that is recessed to help keep your fingers dry during testing.

Side Indicator

Side Indicator

One side of the slide will have a circle indicator so you know which side was used for testing which type of contaminant.

Dual sided paddle
