Dipslides - All you need to know

A dipslide is a means of testing the microbial content of liquids. This is a common method of monitoring and measuring microbial activity within many systems and commonly cooling systems. Usually the use of a dipslide is the first line of defence for the testing of microbial issues that could be caused to manufacturers and machine shop fluid systems. 

Dipslides consist of a plastic barrier which bears a sterile culture medium which can be dipped into the liquid being sampled. The resulting microbial colonies are estimated by reference to a chart. 

Dipslides are usually incubated for 48 hours after use and any subsequent bacteria in the sample water will grow and form colonies.

Gastec Smoke Tubes - How do they work?

Gastec smoke tubes are used in the field or workplace to visualise airflow behaviour within air ducts, and to detect leaks within fume hoods. The tubes can generate white smoke to provide a visual of the leaks/air flow. The slightest air movements can be seen by eye so that the origin, course and speed can be tracked. Gastec smoke tubes creating white smoke What are smoke tubes? A smo...
