Pressure cap for glass tubes

The high quality of our range of disposable glass culture tubes and screw threaded tubes is reflected in the uniformity of their wallthickness, shape of their bottoms, close tolerances, well formed bottoms and well moulded screw-neck.

All of our tubes are fully annealed at temperatures above 500 ºC to eliminate contamination, reduce breakage and increase strength.

The majority of our tubes are packaged in plain outer cases.

Each tube is polished individually.

Culture tubes:

They are available in either borosilicate or soda lime glass. Both glasses differ primarily in their chemical composition and their chemical resistance.

Borosilicate glass is a type of glass with a higher resistance to thermal shock.

For this reason borosilicate glass is more suitable when tubes are intended to be heated or cooled rapidly.

Soda lime glass is a more economical alternative and suits for most culture medium,bacteriological and laboratory applications where the tube will not be subjected to extreme temperature changes.

Screw-neck tubes are ideal for tissue culture and general bacteriological work.

Tubes are supplied with standard GPI finishes.

The screw – neck vials are made of borosilicate glass and are basically used for diagnosis, pharmaceutics, chemicals, laboratory analysis, storage of liquids and

powders. The caps presented are manufactured in autoclavable polypropylene with internal silicone joint.

Different packagings are available, depending on the model of tube:

Boxes: sturdy cardboard boxes. Each box contains small shrink-wrapped cases.

Tubes are presented horizontally.

Trays: sturdy shrink-wrapped cardboard trays. Tubes are presented vertically.

Pressure cap for glass tubes:

Made of polypropylene, autoclavable up to 121 ºC.

Recommended for glass tubes.

Codes 916100, 816100, 916150, 816150 and 816160.
