2 L PC Erlenmeyer Flask Baffled Concave Bottom with PTFE-Lined Screw Vent Cap Sterile Autoclavable Individual Packed Biofargo

Description

Biofargo® Erlenmeyer Flasks are ifor suspension cell culture and storage applications, including bacteria, fungi, animal cells, and plant cells. These disposable flasks provide an economical alternative to traditional flasks, plates, and dishes.

Specification

Structural Design

• Cap options: available in vented or flat-top designs.

• Seal integrity: features an integrated molding design inside the closure that fits tightly against the beveled bottle neck, ensuring a perfect fit between cap and bottle and maintaining a T-shaped leak-proof system without gaskets, minimizing contamination risk.

• Threads: the bottle neck and cap use tapered threads for smooth screwing and easy tightening, superior to low-quality round threads.

• Anti-eccentric and anti-slip stop at the bottle neck to prevent slipping during handling.

• Bottle body: fully transparent with high gloss (light transmittance ≥ 80%), uniform wall thickness, and conical shape for pressure resistance.

• Concave, streamlined bottom design for enhanced stability during use.

• Clear graduation marks for easy observation of liquid volume.

Manufacturing Process

Produced under cGMP standards with no human contact, ensuring excellent product consistency.

Sterile, non-toxic, and free from heat sources.

Gamma-irradiated sterilization with individually sealed sterile packaging for ease of use.

Made domestically with stable supply and cost control.

Features

• Manufactured from medical-grade polycarbonate (PC), compliant with ISO 10993 and USP <661>.

• Bottle Body: Made of high-transparency polycarbonate (PC) with excellent mechanical strength and high-temperature resistance.

• Bottle Cap: Designed with a PTFE hydrophobic vent membrane that maintains sealing integrity and ventilation performance even when in contact with liquids.

• Polycarbonate (PC): A thermoplastic material combining the advantages of metal, glass, and plastic. It is transparent and maintains excellent thermal stability over a wide temperature range from -130°C to +130°C.

• Polyethylene Terephthalate Glycol (PETG): A transparent plastic known for its clarity, toughness, and airtightness, making it an ideal material for manufacturing storage and culture vessels.

• PC material offers high transparency, strong impact resistance, oxidation resistance, and heat resistance up to 121°C.

• Clear and accurate graduations on the outer wall provide convenient and precise volume reading.

• Available with sealed caps or vented caps featuring a 0.22 μm PTFE membrane that allows gas exchange while preventing contamination.

• Automated production in self-owned GMP workshops ensures consistent quality, stable supply, and cost efficiency.

• Certified DNase/RNase-free, pyrogen-free, and precipitation-free.

• Individually packaged and radiation-sterilized, achieving the highest Sterility Assurance Level (SAL 10⁻⁶).

• Suitable for small-scale development, cell culture scale-up, and training applications.

Application

• Designed for the cultivation of various suspension cells, including 293 and CHO.

• Widely used in process development, biopharmaceutical production, vaccine development, and protein research.

• Ideal for small-scale experiments, preliminary studies, media optimization, and pilot screenings of bacterial or mammalian cell cultures.

• Compact 125 mL Erlenmeyer Flask ensures efficient gas exchange and nutrient utilization in limited-space laboratory setups.

• Suitable for small-scale process development and stepwise scale-up culture stages.
