Petri dishes, the ubiquitous shallow glass dishes used for culturing were designed to allow an even distribution of culture medium and guarantee a distortion-free view. The lids of the Petri dishes rest directly on the base, preventing disturbance of the contents from the turbulent airflow. This is well suited for reactions with long incubation times, at high temperatures, or with sensitive culture media.
DWK Life Sciences KIMAX® Petri dish features a reinforced beaded edge to resist mechanical breakage and help in centering the bottom inside the cover. We’ve incorporated a combination of different color marking spots to make identification of parts when sorting, selecting, and assembling pairs quick and easy.
The concave circular shape of the watch glass results in a very versatile lab vessel, well-suited for working with very small quantities (e.g. preliminary samples). In addition, the watch glass makes a handy beaker cover, can hold solids when being weighed, and can be used as an evaporation surface for liquids. Ours are available in borosilicate or soda-lime glass.
Wide low-form KIMAX® crystallizing dishes provide a large liquid surface that favors the
evaporation of excess solvents. The flat shape, as well as the flat bottom, provide even
evaporation of solvents and thus the crystallization of solids from solutions and suspensions.
We recommend the glass Feigl spot plate with its cup-like depressions for use in analytical chemistry to detect certain substances with reagent solutions and to observe reactions on a small scale. Spot tests can not only be used to identify reactions but can also be used for purity testing.
