In filter cassettes, numerous mesh layers retain the oil and grease particles and eliminate the smoke from the kitchen. The cassette filter is composed of aluminium or stainless steel. The cassette stainless steel filters are a bit more expensive than the aluminium ones. But cassette filters made of aluminium are easy to handle, lighter, and require careful maintenance. On the other hand, stainless steel models are hard to handle, bulkier, and are easy to clean.
Tangential flow filtration devices are Easy to set up and use. You just need to simply connect the TFF device to a pump and pressure gauge(s) with tubing and a few fittings, add your sample to the reservoir, and begin filtration. It is easier to set up and much faster than dialysis. Higher concentrations can be achieved in less time than when using centrifugal devices or stirred cells. The device concentrates and diafilters a sample on the same system, saving time and avoiding product loss. It can be scaled up or scaled down. Materials of construction and cassette path length allow conditions established during pilot-scale trials to be applied to process scale applications.
Tangential flow filtration system is a rapid and efficient method for separation and purification of biomolecules. It can be applied to a wide range of biological fields such as immunology, protein chemistry, molecular biology, biochemistry, and microbiology. TFF can be used to concentrate and desalt sample solutions ranging in volume from 10 mL to thousands of liters. It can be used to fractionate large from small biomolecules, harvest cell suspensions, and clarify fermentation broths and cell lysates.
