Unless otherwise noted, all chemicals come packed in a twist-tied plastic bag in a sealed, reusable plastic tub. Some, very light-weight, high-volume chemicals (like air float charcoal, lampblack, and Cab-O-Sil) are packed in boxes instead of tubs. Each container is labeled and contains a material safety data sheet (MSDS) for that chemical. The chemicals we supply are generally technical grade, sometimes better. Technical grade is generally defined as "chemicals of reasonable purity".
