About Our Microbiological Dipslides (General Purpose) Box of 10

This is a general purpose microbiological dipslide that can be used for testing a wide variety of samples.

Suitable applications include:

  • Food / Beverage
  • Industrial waters

  • Environmental
  • Laboratory
  • Laundry
  • Koi pond water

This microbiological dipslide features Nutrient agar TTC on one side and Malt Extract agar on the other side.

Nutrient agar is a general purpose media that will support the growth of / test for aerobic bacteria / microbes. It will grow a wide range of micro-organisms . This agar is often used to test the 'general health' of a sample. The nutrient agar on this dipslide contains TTC (red spot dye). The dye in this agar allows for easier viewing of microbiological colonies after incubation. Due to the dye, the colonies will appear as red dots.

Malt Extract agar will support growth of / test for yeasts and moulds (fungi). Again, this is a broad spectrum agar that will grow a wide variety of yeasts and moulds. Yeasts will grow as pale / straw colonies and moulds will usually appear as fluffy colonies. Examples of the appearance of colonies on both agars can be seen in the charts below.

These microbiological dipslides come in a pack size of 10 slides per box. The slide has a flexible paddle and is located inside a shatterproof container. 

Flexible microbiological dipslide paddle

How to use the General Purpose (DS-GP) Microbiological 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.

Surface testing

Step 2 : If Surface Testing

For surface testing, press the General Purpose 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 General Purpose 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.

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.

Q

What are Microbiological dipslides?

A

Microbiological dipslides are plastic paddles coated in a prepared culture media (Agar). They are used for microbiological monitoring of a surface or liquid. Each agar tests for a different group of micro organisms and will show growth if a particular contaminant is present in a sample.
