Do you still sell the 125mL wide mouth vessels with attached lids? Catalog #?

Please see item SC600.

Is it class A? I am something looking for class A digestion cups 50 ml which can be digested in acid medium in 120 degree centigrate for 1 hour . Do you have something like that?

These vessels are tested for volume accuracy at all graduation lines by the procedures set forth in ASTM E542-01, Standard Practice for Calibration of Laboratory Apparatus. Volume accuracy is found to be within the Class A tolerance set forth in ASTM 1272-02, Standard Specification for Laboratory Glass Graduated Cylinders. However, glassware, not plastics, are Class A certified. We do not sell Class A certified digestion vessels.

The cap is made of polypropylene with a polyethylene liner.

Is product SC490 able to be autoclaved

The SC490 is made of polypropylene, which can withstand temperatures up to 130C. Since most autoclaves operate around 122C, the SC490 should be ok.
