High Efficient Erlenmeyer Flask, PC, Baffled Bottom

The High Efficient Polycarbonate Baffled Bottom Erlenmeyer Flasks are available from 2000 mL to 5000 mL and come with either a plug seal or a vent filter cap. NEST baffled Erlenmeyer Flasks is suitable for the cultivation of suspension cells and bacteria. These high-efficiency, large-volume culture flasks allow cells to show strong viability with large expression amounts of proteins in the culture of mammalian cells and insect cells. During the culturing process, the use rate of the shaker is significantly increased, and the survival rate and viability of cells are both dramatically elevated. NEST culture flasks also provide high repeatability, which allows high inter-batch consistency of cell growth and yield.

Features:

• The groove design at the bottom of the flask makes the culture medium form a vortex during the flow process, which can increase the contact area with oxygen and increase the amount of dissolved oxygen
• The bottle is made of medical-grade polycarbonate (PC), which has high transparency, great impact resistance, oxidation resistance, and can withstand a high temperature of up to 121°C
• Choice of plug seal cap or vent filter cap
• The vent filter cap is equipped with a 0.22 μm breathable film 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 scale on the flask body, made by injection molding, is clear and accurate when looked at from the outside, making it easier to observe the filled liquid volume of the culture medium
• Suitable for suspension cell culture or bacterial culture and can also be used for medium preparation, mixing, and storage
• Individually packaged in sterile bags
• 2000 mL and 3000 mL High-Efficiency Flasks:
  • These flasks are optimized with lengthened necks that are convenient for customers to grip and can prevent the hand of the customer from being too close to the flask mouth when pouring liquid or holding the flask. Additionally, they meet the aseptic operating practices of pharmaceutical companies.
  • The bottom of the 3000 mL high-efficiency shake flask is optimized to reduce the space occupation, significantly improving the use rate of the shaker, reducing the R&D and production costs of customers
• 5000 mL High-Efficiency Flasks:
  
  • Designed with a detachable nylon handle, making it easy to grip and for flexible applications; the design for preventing liquid residue at the mouth facilitates pouring
  • The high fit between the handle neck and the flask body can prevent slipping
