Caplugs Evergreen's test tubes are ideal for a variety of general laboratory applications, offering more sizes than any other manufacturer.
Tubes are bulk packed, non-sterile, without caps.
Polystyrene tubes provide clarity and are appropriate for use with mild acidic solutions, alkali solutions, alcohols, and salt. Polypropylene tubes are more chemically resistant and are appropriate for use with organic solvents, stronger acids, alkalis, alcohols, hydrocarbons, and ketones. Polystyrene tubes withstand up to 8,200 x g and polypropylene tubes withstand up to 10,000 x g.
Caps to fit are sold separately.
