About the plate count (pca) ttc + macconkey 3 dipslides (neutralisers) (box of 10)
This dipslide has Plate count agar on one side and MacConkey 3 agar on the other side. The plate count agar contains TTC (red spot dye) which makes it easier to view and count the colonies as they appear as red spots. The SCNT dipslide contains neutralisers (germicide inhibitor) for disinfectants present in the sample, this provides accurate readings in such tests. This dipslide measures a total count on the front side and coliforms count on the other.
It comes in a pack size of 10 slides per box. The slide has a flexible paddle and is located in a shatterproof container.
Each dipslide features a virtually unbreakable and flexible paddle allowing for even, full surface testing.
Easy Run Off Design
Due to the design of the dipslide, fluids will drain off quickly during testing.
Each slide has a handle built into the lid that is recessed to help keep your fingers dry during testing.
One side of the slide will have a circle indicator so you know which side was used for testing which type of contaminant.
Each dipslide is dual sided to allow multiple contamination testing with one test.
Thick Reliable Agar
Each agar is thick (approx 4mm) and raised above the dipslide to allow for easy surface testing.
Plate Count Agar - Used to test food and water, in particular dairy products. Plate count agar provides a general count of viable organisms in a sample. Contains TTC (red spot dye).
MacConkey 3 Agar - Tests for coliforms (indicator organisms) and suppresses non coliform bacteria. Often used in food safety testing.
This dipslide includes neutralisers. These neutralise common germicides which means that recovery of damaged organisms can be attained. This is particularly useful as disinfectant traces can interfere with results and can lead the test to not uncover the 'full picture'. It also assists in testing and evaluating cleaning regimes.
How to use the SCNT dipslide
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).
A comparison chart is included so you can easily compare your results.
Step 1 : Remove slide
Carefully remove the sterile Plate Count / MacConkey 3 TTC / Neutraliser dip slide from its tube ensuring that no contact is made with the agar (to avoid contamination).
Step 2 : If Surface Testing
For surface testing, press the Plate Count / MacConkey 3 TTC / Neutraliser 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.
Step 2 : If liquid testing
For liquid testing, immerse the Plate Count / MacConkey 3 TTC / Neutraliser dipslide into the fluid for 10 seconds then remove and allow to drain for a few seconds.
Step 2 : If swab testing
Apply a sample of the test substance to a sterile swab and gently apply to the agars.
Step 3 : Incubate Slide
Label the tube with the included stickers then place the slide into an incubator and allow to incubate.
Step 4 : Compare results
Count the amount of colonies that have grown on the slide and compare them to the comparison chart provided.
