Feature1. According to c-GMP standard production,no personal contact,great consistency.2. The bottle cap using high-strength HDPE material and is designedwith a PTFE hydrophobic and breathable membrane.After contact withliquid，it will not affect the sealing and ventilation effect of thebreathable membrane.3. The scale is clear and accurate, which is convenient for observingthe medium capacity4. Four capacities of 125ml, 250ml, 500ml and 1000ml5. Aseptic individual packaging The difference between baffle shake flask and ordinary conical erlenmeyer flaskIn the era of rapid development of various technologies, cell culture consumables are also constantly updated and iterated, and the baffle shaker is a relatively novel cell culture consumable. What are the differences between the two standard flasks?First of all, in terms of shape, both of them adopt a triangular design, and the bottle caps are also divided into two types: sealed caps and breathable caps, and the specifications are roughly the same. The main difference between the two is the bottom of the bottle. The bottom of the ordinary shaker is flat, while the bottom of the baffle shaker has grooves. The raised parts of these grooves form a baffle inside the bottle, so name.The special design of the baffle flask has two functions. One is to reduce the phenomenon of cell clumping. Shaking with a shaker can effectively reduce the viscosity caused by free DNA and cell debris, and reduce the occurrence of cell clumping growth. In addition, the baffle at the bottom can also prevent the vortex phenomenon generated by the medium during shaking, making the medium more uniform, which also has a certain effect on reducing cell clumping. The second is to increase the amount of dissolved oxygen. The baffle at the bottom of the bottle can increase the amount of dissolved oxygen in the medium, effectively promote the full contact between cells and air, and help cells grow better.In general, the main difference between baffle shake flasks and ordinary shake flasks is the difference in the bottom of the bottle. The new type of bottle increases the amount of dissolved oxygen and is more suitable for cell lines that require a large amount of oxygen.Two characteristics of baffled shaker erlenmeyer flask1. Reduce cell clumpingIn the process of suspension cell culture, cell clumping growth is often encountered. The reasons are various, such as the lack of re-suspension after centrifugation, or the problem of serum in the medium, or the concentration of calcium and magnesium ions. changes in the adhesion between cells. The baffle flask is shaken with a shaker, which can effectively reduce the viscosity caused by free DNA and cell debris, and reduce the occurrence of cell clumping growth. In addition, the baffle at the bottom can also prevent the vortex phenomenon generated by the medium during shaking, making the medium more uniform, which also reduces the chance of cell clumping to a certain extent.2. Increase dissolved oxygenThe breathable cap is an important channel for the gas exchange of the baffle shaker bottle. Through the breathable function of the breathable membrane, on the one hand, it can promote the gas exchange in the bottle, and on the other hand, it can effectively prevent the contamination of microorganisms. The baffle at the bottom of the bottle can increase the amount of dissolved oxygen in the culture medium, effectively promote the contact between cells and air, thereby improving the gas exchange efficiency and allowing cells to grow better.The special design of the baffle flask is mainly due to the folds at the bottom of the bottle, which reduces cell clumping, increases dissolved oxygen, and provides good conditions for cell growth.
