Drigalski Spatula

The Drigalsky spatula is an essential instrument in microbiological streaking techniques, designed for the uniform distribution of cell suspensions over the surface of culture media in Petri dishes.

Its design incorporates a finely polished triangular end that allows the inoculum to be spread homogeneously without damaging the agar, favoring the isolation of well-separated colonies and reproducible results.

It is available in two material variants:

• Stainless steel, ideal for intensive use and repeated sterilization cycles.
• Soda-lime glass, which allows for better visualization during streaking and more precise control of contact with the medium.

Both versions offer excellent chemical resistance, stability against autoclave sterilization processes, and a long service life in laboratory environments.

The straight shank provides a firm and ergonomic grip, facilitating control during inoculation. Its polished finish minimizes the risk of cross-contamination and allows for quick and effective cleaning.

This instrument is essential in microbiology, biotechnology, quality control, and teaching laboratories where microbiological cultures are routinely performed.
