VM CRUCIBLES
•
A light weight. 13 ml nickel-chromium alloy cru cible which will withstand repeated heating to 1000° C with no appreciable change in weight.
PARR V M Crucibles were developed especially for determining volatile matter in coal, coke and chars, and for general ignition, ashing and incineration pur poses where free acids are not present. They offer an inexpensive substitute for noble metal crucibles for use where extreme resistance to corrosion is not essential. Ask your PARR Dealer for com plete information, or write to the factory for Spec. No. 3100
