Lactose intolerance is common, but is actually a recessive genetic trait! Humans and other mammals are only meant to drink milk as infants and as they grow, they lose the ability to digest lactose. As populations began to develop, the domestication of cows and drinking milk into adulthood became more common, leading to a tolerance for lactose. Learn about variation, inheritance, and the role of DNA and proteins in expression of traits in this three-part laboratory activity.

This digital coolant refractometer measures the concentration and freezing point of the coolants ethylene glycol and propylene glycol. This unit has 4 scales (ethylene glycol, ethylene glycol freeze point, propylene glycol, and propylene glycol freeze point) and comes with a 1-year warranty.

Simplify potassium testing with precise, pre-measured tablets. Perfect for consistent, hands-on water analysis in education and fieldwork.

Use gel electrophoresis to compare DNA fingerprints from the shark attacks and determine if a single shark is to blame.

Portable exhausters for use with XPert™ balance enclosures and weigh boxes, Precise™ HEPA-filtered glove boxes, and Protector™ XVS ventilation stations, demonstration hoods, and workstations. Exhausters use carbon and/or HEPA filters to remove hazardous powders, particulates, or vapors from the exhaust air stream, returning filtered air to the environment. No ducting to the outside is required.

To meet increasing demands for a dedicated, professional polarizing microscope, Motic introduced the BA310Pol for observation of birefringent samples with efficiency and reliability
