Glycerol, Molecular Biology Grade
Product Size Cat.# Price ($)
Glycerol, Molecular Biology Grade
For Research Use Only. Not for Use in Diagnostic Procedures.
1,000 ml H5433 102.00
Description: Glycerol is used for storage of enzymes at low temperatures. A
50% (w/v) glycerol solution will not freeze at –20°C. Glycerol is often used as a
component in electrophoresis loading buffers because of its density (1.26g/ml).
In addition, glycerol gradients can be used in the purification of bacteriophage
or proteins. Cat.# H5433 is anhydrous glycerol with a purity of ≥99.5%.
Properties:
• Purity: ≥99.5%.
• Calcium: ≤2ppm.
• Magnesium: ≤1ppm.
• Lead: ≤5ppm.
• Zinc: ≤1ppm.
• A 260 at 10%: ≤0.05.
• A 280 at 10%: ≤0.05.
Features:
• Quality Tested: Each lot of glycerol is tested and certified to be free of
DNase, RNase and protease activity.
Storage Conditions: Store at 22–25°C.
