Erlenmeyer Flask - Vent Cap - flat bottom, PC – Witec AG

Optimize Your Cell Culture: High-Quality Erlenmeyer Flasks

Erlenmeyer flasks are the ideal choice for suspension cell culture, essential for screening industrial microbial strains, large-scale proliferation tests, and seed cultures. They are also versatile for media preparation, mixing, and storage. Plus, they offer a more cost-efficient alternative to culture bottles, dishes, and spinner bottles.

• Clear, Even, Transparent Body: Features clear and accurate graduations for precise volume observation.
• Lengthened Flask Neck: Designed for easier gripping and pouring, with a liquid sticking-resistant design.
• Autoclavable PC Material: Supports single autoclave sterilization (repeated sterilization is not recommended; vent cap must not be autoclaved).
• Extremely Low Extractables & Excellent Biosafety: Multiple assessments verify high safety standards.
• 0.22 µm PTFE Hydrophobic & Breathable Vent Cap: Facilitates continuous gas exchange while ensuring sterility.
• PETG Material (for specific variants): Shrinks under autoclave sterilization to reduce biohazard residue.
• 100% Air Tightness: Guaranteed no leakage with a 100% passing rate on production line tests.
• Sterilized by Irradiation: Ensures SAL 10⁻⁶ sterility.
