The Avestin EmulsiFlex-C5 homogenizer is a technically and visually outstanding device that is delivered completely ready for connection with a compressed air control system. 1. The pump . The EmulsiFlex-C5 homogenizer has a compressed air/compressed gas operated high pressure pump developed by AVESTIN®, which contains no sealing rings that come into contact with the product. The only plastic seal is the piston seal made of UHMWPE (Ultra High Molecular Weight Polyethylene). A specially developed pump motor control valve ensures particularly quiet operation. 2. The homogenizing valve . The standard EmulsiFlex-C5 device is equipped with a pneumatically regulated, dynamic homogenizing valve, which does not contain any rubber sealing rings. The only plastic seal is a Teflon ring to seal the homogenizing valve system. All other seals consist of precision-machined metal-to-metal or metal-to-ceramic seals. 3. Capacity/pressure . The sample throughput for all air-operated pumps depends on the set operating pressure. The EmulsiFlex-C5 device achieves a throughput of 1-5L/h. The minimum usable sample quantity is 7mL. The substance loss during processing is less than 1mL. The homogenization pressure can be freely adjusted in the range of 30 - 2000 bar. 4. Temperature regulation . The temperatures at the inlet and outlet can be regulated by using a suitable heat exchanger. In addition, the entire device can be immersed in a water bath to control the sample material temperature. 5. Cleaning and sterilization . Hot water, ethanol, acetone and various other cleaning agents can be pumped through the device for cleaning purposes. Liquid residues can be removed by flushing with compressed air/gas. The entire device, including the homogenization valve, can be completely dismantled for cleaning and maintenance purposes. All parts that come into contact with the product are autoclavable and can be validated in accordance with FDA guidelines. The pump inlet pieces can easily be connected to a steam cleaning source for sterilization at 120-130°C (steam-in-place). 6. Requirements for commissioning. For laboratory use, a nitrogen pressure vessel or a small compressor is sufficient. The required gas pressure depends on the specific application. For the production of most dispersions, emulsions, liposome dispersions and for E. coli finishing processes, compressed air of 6 - 8 bar is sufficient.
