Crucibles with lids, alumina

Supplier: Mettler - Toledo

These reusable crucibles made from alumina (aluminum oxide) are used for TGA measurements. After mechanical cleaning, store them in water (or possibly even in 10% hydrochloric acid) because many salts are soluble in water. Oxides form chlorides in hydrochloric acid, which can be removed by rinsing. After drying, heat the crucibles to red heat to ensure that no weight loss occurs when they are used.

Bis(2-hydroxyethyl)amino tris(hydroxymethyl)methane (BIS-TRIS) ≥99% (by titrimetric analysis), white powder

Supplier: MP Biomedicals

Bis-Tris is zwitterionic buffer, an amine buffer similar to Tris. It exhibits only a very small shift in dissociation constant with respect to temperature. Hydrochloric acid can be used to adjust pH for a Bis-Tris buffer to the desired pH.
