Envirocheck® Dip Slides

Envirocheck® Dip Slides are easy-to-use solutions for microbial surface or liquid testing. Unscrew the cap on the tube and remove the Envirocheck® Dip Slide from the tube, taking care not to touch the agar surfaces. Check for any dehydration or contamination before use.

Surface testing
With two fingers hold the terminal end of the paddle against the surface to be tested. Press down on the spike to bend the paddle, still holding the slide by the cap. With firm and even pressure press one of the two agar sides against the surface to be tested. Take care not to smear the agar over the test area. Repeat the procedure with the other side of the paddle on an area adjacent to the initial test site. Replace the slide back into the tube and close tightly.

Liquid testing
Dip the Envirocheck® Dip Slide into the test fluid for about 5–10 seconds so that both agar surfaces are totally covered. In case of insufficient liquid, pour over both surfaces of the slide. Tip slide on clean absorbent paper to drain off excess fluid. Replace the slide back into the tube and close tightly.

Incubation
Place the container in an upright position into an incubator, e.g. CULTURA® Mini Incubator 1.13311.0001 (230-V version) or 1.15533.0001 (110-V version) for 24–48 hours at 35–37 °C (for bacteria) or for 2–7 days at 27–30 °C (for yeasts and molds). Duration and temperature of incubation may be varied according to individual requirements.

Interpretation of results
The results of using Envirocheck® Dip Slides are semi-quantitative, indicating the
degree of contamination in the tested environment.
