Anhydride Purity Bath

Molten samples of maleic or phthalic anhydride are compared with Platinum-Cobalt color standards for determining sample purity and the qualitative stability in the presence of contaminants. High color content normally indicates contamination. Conforms to ASTM D3366 specifications Redundant over-temperature protection circuitry Microprocessor-based temperature controller Electrically heated aluminum block features a microprocessor-based temperature controller with over-temperature protection circuitry and a dual LED temperature display. The heating unit provides temperature stability, heating rates, and minimal temperature gradients which exceed ASTM specifications and is housed in an insulated steel cabinet with a chemically resistant painted finish. Up to six samples can be tested at a time using Nessler tubes. Visual color comparisons are made against solutions of Platinum-Cobalt color standards. 115V 60Hz 220-240V 50/60Hz lxwxh,in.(cm): 12x12x21 (31x31x54) Net Weight: 65 lbs (30 kg) Shipping Weight: 76 lbs (34.5 kg) Dimensions: 28x24x20 in.
