Chemglass Life Sciences Flask, Erlenmeyer, 5L, High Efficiency, Polycarbonate, Baffled Bottom, with Vent Filter Cap, Sterile
The imported medical-grade polycarbonate that meets with the requirements of ISO 10993 USP<661> is chosen as the raw materials, which has high transparency, great impact resistance, oxidation resistance and can withstand a high temperature of up to 121 degreesC. The scale is clear and accurate when looked at from the outside, which facilitates the observation of the volume of culture medium. The vent cap is equipped with a 0.22um breathable filter which is air-permeable and water-proof to efficiently prevent the passing of micro-organisms and contamination and to ensure gas exchange for good growth of cells or bacteria. The products have undergone the tightness test, drop test, high-temperature and high-voltage tests, flatness test, tensile test, endotoxin test, sterilization test, DNA/RNA enzyme-free tests and cell culture test, all the results of which meet the corresponding quality standards.

Alkali Scientific Erlenmeyer Shake Flask, PETG, flat bottom w / vented screw cap, sterile, indiv wrapped, 125mL, 24/cs
• Vented screw caps • Flat or baffled bottoms • Gamma sterile (SAL 10-6) • Pyrogen free and RNase/DNase free • Individually wrapped Erlenmeyer Shaker Flasks are made of polycarbonate, PETG or styrene/butadiene (Jumbo Flasks only). The polypropylene screw caps are vented with 0.2µm membranes to increase air transmission and enhance cell growth. The mouth size conforms with the international SBS standard, for quick, secure connection to bioreactor equipment.Polycarbonate flasks and Jumbo Fernbach flasks have baffled (ribbed) bottoms to provide increased oxygenation and mixing efficiency even at lower shaking speeds. All flasks, regardless of size, are individually wrapped and gamma sterilized to SAL 10-6, and they are free of RNase, DNase, pyrogen, endotoxins and human DNA. Polycarbonate Flasks are autoclavable at 121°C and 15PSI for 30 minutes.
