Flat-top stopper caps for 17 mm tubes, natural, Case of 1000

Product Details

For test tubes.

Precision-molded stopper caps are available for every size of Evergreen test tube. Choose from either standard caps (300-2900 series) or our flat-top style (300-4700 series). 300-2900 series caps for 12 mm tubes are available in six colors.

For culture tubes.

Overfitting caps for use with sterile culture tubes have two positions: loose for aerobic culturing and tight for anaerobic culturing and leakproof sealing. Caps for culture tubes are gamma irradiated for sterility.

For sample cups.

Perforated caps help minimize variation caused by evaporation during processing. Non-perforated caps are appropriate for short-term storage.

Additional Information

Multipurpose

Polystyrene tubes provide clarity and are appropriate for use with mild acidic (except oxidizing acids) or alkali solutions, alcohols (except higher alcohols) and salt. Polypropylene tubes are more chemically resistant and are appropriate for use with organic solvents and stronger acids (except oxidizing acids), alkalis, alcohols, chlorinated & aromatic hydrocarbons (except xylene) and ketones.

Widest selection

Evergreen offers more sizes of tubes than any other manufacturer. Tubes are bulk packed, non-sterile, without caps (except tubes with screwcaps). Stopper caps and sterile tubes are also available.

Internally-ribbed tubes

Internally-ribbed 12 × 75 mm tubes are ideal for use in antibody coating and/or protein adsorptions. Six slanted ribs increase useful surface area.
