petri dishes

Did you know?

... that petri dishes were named after the German bacteriologist Julius Richard Petri (1852-1921) who invented it in 1877 when working as an assistant to Richard Koch.

Not only are these dishes convenient for cultures, plant germination, agar-based bacteria samples, and many other day-to-day laboratory uses, but they are conveniently designed to fit under the microscope.

SKS carries the polystyrene petri dishes in a variety of colors: red, blue, amber, and clear, which are ideal for identifying different batches of work of work in laboratories. All petri dishes are manufactured under strict aseptic conditions.

These inexpensive polystyrene dishes provide a versatile function and can be disposed of after the experiment is completed.

disposable cotton swabs

Disposable cotton swabs are available in different lengths, with varying sized heads. Cotton swabs are manufactured of USP grade purified cotton firmly attached to one end of wood shaft and may be autoclaved. Useful in bacteriology labs for inoculating broths, plated media or for obtaining culture specimens. Also useful for cleaning delicate instruments.

disposable enviro swabs

The disposable Enviro Swabs are precision molded from superior grade open cell polyurethane 100 ppi foam, consistently demonstrating low particulation and chemical cleanliness. They are non-silicone formulated, hot-wire cut and slit (not die cut and sealed). A thermally bonded head to handle eliminates the use of adhesives for maximum reliability and performance. These swabs are non-linting and non-scratching. They may be used with alcohol, acetone, oils, greases and solvents.
