The TPO dipslide tests for bacteria, yeasts and moulds. The agars on this dipslide are used specifically in the food industry. The plate count agar tests for total count bacteria / viable organisms. This agar contains TTC (red spot dye) making colonies easy to view / count due to their red colour. OGYE agar tests for yeasts and moulds (fungi).
This dipslide contains neutralisers. Neutralisers are added to agars to ‘neutralise’ the effect of disinfectants / germicides. The neutraliser aids in the recovery of surviving / viable organisms that have been damaged but not killed by cleaning chemicals. This is useful if you wish to test the efficacy of cleaning agents. The neutraliser will help you get a more accurate result without the efficacy of your cleaning regime being overestimated.
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.
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.
Each agar is thick (approx 4mm) and raised above the dipslide to allow for easy surface testing.
Plate Count Agar - PCA is a general growth medium used to provide a 'total count' / detect viable organisms in food and water. Mainly used in dairy testing. This agar includes TTC (red spot dye) which means that colonies grow / appear as red spots. Contains neutralisers.
OGYE Agar - This agar contains an antibiotic called Oxytetracycline. Due to this, the dipslide should not be incubated at temperatures above 25 degrees Celcius. OGYE agar detects yeasts and moulds in food. Contains neutralisers.
How to use the TPO 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 120 hours).
A comparison chart is included so you can easily compare your results.
Carefully remove the sterile Plate Count TTC / OGYE + neutraliser dip slide from its tube ensuring that no contact is made with the agar (to avoid contamination).
For surface testing, press the Plate Count TTC / OGYE + 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.
For liquid testing, immerse the Plate Count TTC / OGYE + neutraliser dipslide into the fluid for 10 seconds then remove and allow to drain for a few seconds.
Apply a sample of the test substance to a sterile swab and gently apply to the agars.
Label the tube with the included stickers then place the slide into an incubator and allow to incubate.
Count the amount of colonies that have grown on the slide and compare them to the comparison chart provided.
