Description
About Seitz Depth Filter Sheets:
Seitz Filter Sheets have a long-lasting tradition of more than 130 years in the depth filtration market and play a key role within the Pall depth filter portfolio. The invention of Seitz filter sheets at the beginning of the 19th century and the market introduction of the Seitz-EK Sheet by Theobald Friedrich and Georg Seitz was one of the most important pioneering achievements in the "cold-sterile" bottling of beverages without the necessity of heat treatment without noteworthy quality losses.
Features:
Using three filtrations mechanisms, including surface filtration, depth filtration and adsorption, Pall depth filter sheets provide a very effective and economical solution for protecting the final liquid membrane against irreversible colloidal clogging. It also provides a high retention capacity for particles and colloids (porosity of 60 – 90), polishing filtration, chill haze removal and microorganism reduction.
Depth Filter Sheets offer high flexibility for different filtration steps (pore size 0.1 – 70 µm) in one unit and used for the following filtration spectrum:
- Coarse filtration
- Clarifying filtration
- Fine filtration
- Microorganism-reducing filtration
