*In April 2018, numerous specifications for individual Aspire PTFE Membranes were revised dependant on improved characterization machines and strategies. Membrane characterization has no influence on the manufacturing course of action to the membranes, and no adjust in performance need to be predicted.
Tetratex membrane filter media is usually a proprietary expanded microporous PTFE (ePTFE) membrane manufactured solely by Donaldson and engineered for high functionality. Tetratex membranes and laminates give these terrific features and Gains:
Find out more regarding the distinctions concerning sintered Porex Virtek PTFE and ePTFE, enabling you to produce educated decisions in your particular apps.
Nominal pore size rankings vary from maker to maker and, As a result, are usually not essentially equivalent. Filters from distinct manufactures with comparable nominal pore sizing rankings may well not actually exhibit very similar retention features.
Steam Sterilization �?Could be sterilized with steam or ethylene oxide for food items, beverage, and pharmaceutical applications
In case you call for secondary processing of sheet and film products and solutions to meet your solution style challenges, Porex also offers a Most popular Converter Method that could serve lesser buy quantities.
After the many air during the pores is displaced, there isn't any longer any area pressure forces and water can certainly enter the pores, displace the very low area stress fluid, and go through the membrane. The membrane will then permit bulk circulation of h2o for so long as the pore keep on being h2o crammed. If your membrane is permitted to dry (i.e. air enters the pores), then it needs to be pre-soaked with a low surface rigidity fluid once again before use with water.
Aspire membranes are assigned a reference pore dimensions In accordance with bubble point examination knowledge but, you will find other solutions to characterize a membrane:
Tetratex membrane filter media might be even further customized to meet your stringent membrane specifications throughout our vast-ranging areas of software expertise, together with:
Hydrophilic membrane filters are usually employed with drinking water and aqueous options. They will also be utilised with appropriate non-aqueous fluids.
Discover our library of our most typical read more capabilities samples to find out firsthand what is achievable with custom made components.
The pores of microporous membrane filters work as tiny capillaries. When hydrophilic membranes appear into connection with h2o, capillary motion associated with surface tension forces leads to the water to spontaneously enter and fill the pores.
The moment all the air inside the pores is displaced, there won't be any longer any surface tension forces and water can easily enter the pores, displace the small surface area stress fluid, and go through the membrane. The membrane will then allow bulk movement of water for so long as the pore remain drinking water loaded. In the event the membrane is allowed to dry (i.e. air enters the pores), then it have to be pre-wet using a lower floor pressure fluid yet again previous to use with drinking water.
