Large Erlenmeyer Flasks sterile - 2L, 3L, 5L – Witec AG

Optimized for High-Efficiency Cell Culture

Large-capacity Erlenmeyer flasks are essential tools for large-scale expansion and culture of suspension cells and bacteria, as well as for the preparation, storage, and transfer of culture media. Their ability to significantly boost cultivation efficiency has led to their widespread adoption in fields like cell biology and microbiology.

These flasks offer a range of features designed for optimal performance and user convenience:

• Durable Construction: The flask body is made from polycarbonate (PC), providing high transparency, strong impact resistance, and high-temperature resistance up to 121°C.
• Ergonomic Design: The circular arc design and frosted finish at the flask neck ensure an easy and secure grip. An anti-drip design at the mouth facilitates smooth pouring.
• Specialized 5 L Features: The 5 L Erlenmeyer flask includes a unique drain neck design to prevent liquid splashing during pouring. Optional handles are also available for improved handling.
• Stable Operation: The fully flat bottom ensures stable placement on tabletop shakers, which helps in effectively controlling foam during cultivation.
• Sterile Gas Exchange: A 0.22 µm PTFE hydrophobic and breathable vent cap allows for continuous gas exchange while maintaining sterility and preventing leaks.
• Quality Assurance: These flasks undergo strict sealing, drop, and flatness tests to guarantee product quality. Each product package includes a batch number for quality traceability.
• Superior Biosafety: They exhibit extremely low extractable levels and excellent biosafety, verified through multiple assessments.
• Sterilization and Purity: All flasks are sterilized by irradiation (SAL 10^-6) and are certified as DNase/RNase-free, non-pyrogenic, and non-cytotoxic.
