Descrição

Aplicação

Dissolve in water to make a 0.1M solution. No pH adjustment is necessary. Guaranteed accuracy: ±0.1 pH units.

Tris has a significant temperature coefficient, so select the mixture to give the desired final pH at the desired temperature.
From 5 °C to 25 °C, the pH decreases an average of 0.03 pH units per °C.
From 25 °C to 37 °C, the pH decreases an average of 0.025 pH units per °C.

The product is cell culture tested. It is also tested for low endotoxin levels and analyzed for the absence of nucleases and proteases.

Outras notas

This product is a pre-mixed combination of Trizma base and Trizma HCl that can be used to prepare a common pH value for Tris buffer.

Certain pH electrodes do not give accurate results with Tris buffers.

Nota de preparo

Trizma solutions can be autoclaved.
