Media filtration

Parker domnick hunter can work with you to reduce your processing costs by careful optimisation of your media filtration system. We can offer products that minimise the size of your filtration system while allowing full batch processing of media within the timeframe required to remove the potential risk of contamination.

The problem

Due to the susceptibility of cell culture to potential contamination, the time allowable to sterilize a batch is often limited to a maximum of 3 hours. To maintain the flow rates necessary to process a full batch within this time, filtration systems are regularly oversized, increasing processing costs and footprint.

The solution

The PROPOR HC dual layer sterilizing grade filter has been specifically designed by Parker domnick hunter with an optimal membrane configuration to maximise capacity. It incorporates a highly asymmetric membrane prefilter layer and can reduce filtration system size while maintaining high flow rates. Batches of media can be processed quickly with reduced system sizes thereby decreasing your processing costs.
