5-Layer Polystyrene Cell Culture Flask

• Polypropylene (PP) or polycarbonate (PC)
• Autoclavable (flasks, caps, and filters)
• 0.22µm filters (silicone membrane or dri-gauze)
• Multi-colored caps
• 3 flask designs with different baffle options

TUNAIR flasks present an improved methodology for the growth of aerobic microorganisms as well as mammalian, insect, and plant cells. These flasks increase culture growth (up to 3X for yeast), and increase productivity over traditional Erlenmeyer flasks. The unique baffling and barrel-shape design increase the turbulence, with a corresponding increase in oxygen absorption. TUNAIR flasks are a unique, high-aeration, reusable cell growth system which increase the availability of dissolved oxygen and improve cell yields. Available in either 300ml or 2.5L sizes.

Baffle options:

No baffle, NO-BAF (normal throw)

2 baffles, HAF-BAF (vortex motion)

3 baffles, FUL-BAF (propeller motion)

These culture flasks are made of a raw polymer which has excellent biodegradable properties. These raw materials can be degraded to carbon dioxide and water by microorganisms in soil. Under normal conditions, the biodegradable flasks can be degraded within a year after disposal or 70 days under composting conditions.

• Made from a bio-renewable polymer
• 0.2um filter cap
• Disposable, non-autoclavable
• Sterile

NEST Transfer Cap for High Efficiency Erlenmeyer Flasks

Two-Way Liquid Transfer Cap
The two-way transfer cap is used along with a 2L, 3L or 5L shake flask to connect a liquid inlet tubing with the required device. The liquid transfer is achieved by connection of a peristaltic pump between the shake flask and the device. Upon completion of the transfer, the transfer cap can be replaced with a vent cap for culture.

Multifunctional Liquid Transfer Cap
Unlike the two-way liquid transfer cap, the multifunctional transfer cap can be directly placed in an incubator for culture after the liquid transfer is completed. It can reach a large air flux. The sampling part is composed of a sampling nozzle and a one-way valve, which can prevent the liquid from flowing backwards during the sampling process and ensure the aseptic sampling. The liquid inlet tubing is provided with a PTFE needle filter, which solves the issue of liquid remaining in the tubing during the feeding process.

Inverted Liquid Transfer Cap
The inverted transfer cap is used along with a 2L, 3L or 5L shake flask to connect a liquid inlet tubing with the required device. When liquid transfer is required, the liquid is transferred under gravity with the inverted shake flask.

Application

It is applicable to liquid transfer and culture during mass proliferation of bacteria and suspension cells.

Product Features

• Closed transfer reduces the risks of contamination during liquid transfer
