CULTURE TUBES

Laboratory Culture Tubes

Culture tubes are essential components in microbiology, biotechnology, pharmacology, and clinical diagnostics laboratories. Designed for the growth and maintenance of microorganisms, cell tissues, or bacterial cultures, these tubes must provide stable, sterile, and easily manageable conditions to ensure the integrity of experimental procedures.

At Pobel, we offer a complete line of culture tubes made of technical glass, ideal for both solid and liquid cultures, and adapted to various types of testing, storage, and transport under controlled conditions.

What Are Culture Tubes and What Are They Used For?

Culture tubes are cylindrical containers with either round or conical bottoms, with or without caps, used to hold culture media intended for microbial or cellular growth. They can be used for culturing in solid media (slanted or upright) or in liquid solutions (nutrient broths).

They are widely used in:

• Clinical diagnostics

• Microbiological and biomedical research

• Pharmaceutical and food production

• Industrial hygiene and quality control

• Academic and school laboratory practices

Technical Features of Our Culture Test Tubes

• Made of high-resistance borosilicate glass or laboratory-grade transparent plastic (polystyrene or polypropylene)

• Available sterile or non-sterile, according to your needs

• Offered with screw caps, snap caps, or cotton plugs to prevent contamination

• Available with flat, round, or conical bottoms

• Standard capacities: 10 ml, 12 ml, 16 ml, 20 ml, among others

Our culture tubes are compatible with autoclaving (for reusable models), standard tube racks, and refrigeration or incubation equipment.
