About the tryptone soya (tsa) + malt extract dipslides (neutralisers) (box of 10)
These dipslides detect moulds / yeasts on one side and total count on the other.
These dipslides come in a pack size of 10 slides per box. The slide has a flexible paddle and is located inside a shatterproof container.
Tryptone Soya Agar shows growth for a wide range of fastidious and non fastidious organisms. The TSA side of our slide can be used as a Microbial Content Test Agar as it includes lecithin and tween in the formulation.
Malt Extract agar is a general purpose medium that tests for yeasts and moulds whilst suppressing bacteria.
These agars are recommended for testing cleanrooms / pharmaceutical environments and are approved for use in the majority of international pharmacopeia.
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.
How to use the TSA / MEA Dipslide
Simply remove the dipslide and immerse in the sample (or press against 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.
Step 1 : Remove slide
Carefully remove the sterile TSA / MEA 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 TSA / MEA 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 TSA / MEA 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.
Dip Slide Storage
Store dip slides in a cool dry place (optimum temperature 8-15 degrees c). Use before the expiry date on the box.
Dip Slide Disposal
Used dip slides should be incinerated, autoclaved or soaked in disinfectant for several hours before disposal.
