Microcentrifuge Tubes - 1.5 mL (500-pack)

1.5 mL microcentrifuge tubes for storing stock solutions, preparing dilutions of growth regulators and vitamins, and small-scale centrifugation. Autoclave-safe polypropylene construction. Use low-binding variants for storing dilute hormone stocks (hormone adsorption to tube walls can alter effective concentration at very low concentrations). Keep a large stock on hand — experienced labs use hundreds per week.
