KIMAX crucible suitable for precipitates to be dried to a constant weight at 110 ºC. At higher temperatures, heating in an electric furnace is advised and crucibles should not be removed until the temperature has been reduced to about 250 ºC. Exposure to sudden temperature changes should be avoided.

Exposure to sudden temperature changes should be avoided.
(12) Individual fritted discs for the fabrication of special apparatus or as a separate filtering device. Three porosities are available: extra coarse (EC), nominal pore size 170-220 microns; coarse (C), nominal pore size 40-60 microns; and medium (M), nominal pore size 10-15 microns.
(2) Gas dispersion tube with a hollow fritted cylinder at the end of the tube. Available with a fine (F), coarse (C) or extra coarse (EC) porosity cylinder.
For the recovery of samples directly from a developed TLC plate, using suction. Recovery of sample is accomplished by elution with an appropriate solvent while the adsorbent is retained on the fritted disc. Size 23 is useful for the recovery of samples from preparative TLC plates.
