About Our potato dextrose (pot dex) + tryptone soya (tsa) dipslides (box of 10)

The PDTSA Dipslide features two different agars (culture medium). One side has Potato Dextrose agar. This agar tests for fungal colonies in dairy / food products. The other side has TSA agar. This agar measures a total count (variety of micro organisms).

If your sample contains microbiological contaminants, colonies will grow on the dipslide agars. You can then count the colonies and compare with the charts provided to assess the level of contamination.

Each box contains 10 dipslides with each dipslide housed within a shatterproof plastic tube.

Industry sectors include

  • Dairy
  • Meat
  • Fruit
