About Our plate count (pca) ttc + macconkey 3 dipslides (box of 10)

The SCT dipslide features two diiferent agars, plate count which measures a total viable count and MacConkey 3 which measures a coliforms count. The dipslide is the same slide as the SC2 but with the addition of TTC* "Red Spot Dye" in the plate count Agar. The red spot dye makes the bacterial colonies grow as red dots which makes them easier to count and compare with the chart.

Plate Count Agar - The plate count agar features red spot dye which means that colonies show up as red spots. This makes them easy to view and count. Plate count is a standard growth medium for assessing a 'total count' of bacteria / viable organisms in a sample. It is used in a variety of applications but in particular food (specifically dairy) and water testing.

MacConkey3 Agar - This agar detects coliforms as well as salmonella and shigella organisms. Gram positive cocci are inhibited with this formulation. MacConkey3 is used to test food and water applications. It is also used to test faecal samples in the poultry and farming industry.

If your sample contains microbiological contaminants, colonies will grow on the dipslide agars.

To use the dipslide:

In Liquids

Simply remove the dipslide and immerse in the sample for approx 10 seconds. Remove dipslide and allow to drain for a few seconds, then replace the slide back into the tube and incubate for a minimum of 24 hours (up to a maximum of 48 hours).

For surface testing, press the SCT 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 SCT 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.

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
