Bottles for Tissue Culture

Quick Answer: Bottles for Tissue Culture are culture vessels, made in clear plastic or glass with a screw cap, in which animal cells or plant tissues are grown in sterile medium. The title of these tissue culture bottles names no filter vent, so gas exchange depends on how the cap is set.

Culture Bottle Formats and Closed Caps

Tissue culture bottles come in several formats. Roller bottles are long cylinders laid on their side on a slowly turning roller apparatus, so adherent cells growing around the whole inner wall are bathed in a shallow layer of medium in turn; they give a large growth surface per bottle for producing cells or virus stocks. Straight or square screw-cap bottles are used for suspension cultures, for plant micropropagation on gelled medium, and for keeping sterile media.

A cap without a filter works as a closed system. In a CO2 incubator the usual practice is to leave it a quarter-turn loose so carbon dioxide can reach the medium and hold the bicarbonate buffer at the right pH, then tighten it before the bottle is moved. Fully closed, the bottle suits cultures buffered with HEPES, transport between rooms, and roller cultures run outside a CO2 incubator. Where a loose cap is a contamination worry, the filter cap version replaces the gap with a membrane vent.

Bottles for animal cell culture are normally supplied sterile, with the inner surface treated so that cells attach, whereas plant culture vessels are often washed and autoclaved for reuse. Which of these this listing is, and its volume, is worth settling before ordering, because it decides how the bottles will be cleaned and sterilised.

Specifications

Uses in Cell and Plant Culture Labs

• Expanding adherent cell lines on a roller apparatus for research or teaching production runs
• Growing suspension cultures of cells or microorganisms in liquid medium
• Micropropagation of plant shoots and callus on gelled medium in biotechnology practicals
• Keeping prepared sterile media and buffers in the cold room

Aseptic Handling of Culture Bottles

• Open bottles only inside a laminar airflow or biosafety cabinet, after wiping the outside with 70% ethanol
• Never pour from the bottle neck over an open culture; use sterile pipettes so the rim stays dry
• Inspect cultures daily for cloudiness or a colour change in the medium, early signs of contamination
• Autoclave spent cultures before disposal, whatever the bottle material

Why Choose LabEquip

Biotechnology departments, plant tissue culture units and cell culture teaching labs order these bottles in batches for practical classes and routine subculturing, often alongside a tissue culture microscope for checking cells through the vessel wall.

Frequently Asked Questions

What is the difference between these bottles and the filter cap version?

These bottles close with a plain screw cap, so gas exchange happens only when the cap is left slightly loose. The filter cap version has a membrane vent in the cap, which lets gases pass while the cap stays fully closed, reducing the risk of contamination through the thread.

Why is the cap left loose in a CO2 incubator?

Most culture media use a bicarbonate buffer that needs carbon dioxide from the incubator air to hold a stable pH. A cap a quarter-turn loose lets that gas reach the medium; a tight cap would let the pH drift.

What is a roller bottle?

A roller bottle is a cylindrical culture bottle turned slowly on a roller apparatus. Adherent cells grow over the whole inner surface and are bathed in medium as the bottle rotates, giving much more growth area than a flask of the same footprint.

Can tissue culture bottles be reused?

Glass and polypropylene bottles are commonly washed and autoclaved for reuse, especially in plant tissue culture. Polystyrene cell culture bottles are generally single-use, because they soften at autoclave temperatures and their treated surface does not survive cleaning.

Are these bottles suitable for plant tissue culture?

Yes, screw-cap culture bottles are widely used for shoot multiplication and callus culture on agar-gelled media. For long cultures some labs prefer vented closures, which reduce humidity and ethylene build-up around the plantlets.

How should cultures in these bottles be checked?

Look at the colour and clarity of the medium daily without opening the bottle. Cloudiness, a surface film, or a sudden yellow or purple shift in a phenol red medium suggests contamination or a pH problem, and adherent cells can be viewed through the wall on an inverted microscope.
