More About This Item

Approved for hot plate digestions and certified for low metals background.

Graduated digestion tubes are certified for volume to 0.5%. The accurate graduations eliminate the need for graduated cylinders and transfer steps, saving you both time and labor costs. The clarified homopolymer polypropylene construction has greater chemical resistance and heat tolerance than commonly used co-polymer polypropylene vials.
These multipurpose tubes include screw-top caps with a polyethylene foam liner—only metals free polypropylene and polyethylene come in contact with your sample!
