Capsule is ready-to-use complex one-piece filter unit, that is in fact Standard cartridge or Mini-Cartridge soldered into a polypropylene housing (body). The design allows using capsules without installing them in a steel filter holder. Capsule has a high strength leaktight polypropylene body and it is equipped with various filtration materials (membrane, fiber, mesh, etc) of a wide range of micron ratings (pore sizes). Most filter cartridges produced by Technofilter RME can be released in Capsule design.

The standard Capsule construction is available for filter cartridges 60 mm, 125 mm, 250 mm, 500 mm, 750 mm and 1000 mm height with the filtration surface area of 0.2 to 4 m² (in case of pleated filter cartridges).

KFM membrane-based Capsules are used for preliminary, fine, polishing and sterilizing filtration of liquid and gaseous media in medicine, microbiological industry, pharmacy, microelectronics, food industry etc. from mechanical impurities and microorganisms with the size above or equal 0.1 μm.

Main applications

Capsules are designed for fast, effective and cost saving filtration of small volumes of liquids and gases. They are particularly effective for critical applications when the filtration of individual batches is required (single use). The possibility of washing and subsequent autoclaving allows the Capsule to be reused until the entire lifetime of the filtration surface is emptied.

Capsule filters allow performing small-scale pilot tests at early stages of development of a filtration system to make a choice of optimal combination of filters, especially for treatment of hard-to-filter solutions without investing costs into stainless steel equipment.

Properties of Capsules

Benefits for customer

Ready-to-use safe complex systems

  • Simple and reliable operation, easy to assemble and use

Wide range of materials (membrane and depth) and filtration areas (from Mini to Maxi Capsules)

  • Allow to optimize the filtration process from the point of economy, filtration rate, micron ratio and the combination of materials.
  • Broad chemical compatibility.
  • The possibility of filtration of different volumes at high flow rates.
  • One capsule can contain various filtration layers (combinations by micron ratings and materials) providing high performance factional separation.

Complete, cost effective and efficient

  • There is no need to invest into stainless steel equipment (filter housing).
  • Allow not to perform continuous flushing and other manipulations that are necessary when using stationary filter holders.

Strengthened body with reliable and convenient connections

  • Capsules are optimized for high flow filtration at low differential pressure.
  • Withstands multiple autoclaving and chemical sterilization. 

Washed, autoclaved and integrity tested before dispatch

  • Ready-to-use filtration systems. Safe in operation.
  • Indispensable for critical filtration in biopharmacy and medicine.

Contain no metal parts or gaskets

  • Chemical resistance depends only on Capsule material.
  • Best choice for solutions containing ferments sensitive to metals.

Produced under clean room conditions in compliance with GMP

The Quality Management System of Technofilter RME meets the requirements of GOST R ISO 9001-2015 (ISO 9001: 2015)

  • Non-toxic, safe.
  • 100% integrity control.
  • Can be supplied sterile (game sterilization, ethylene oxide treatment).
  • Reliable and effective.

Unique labeling

All Capsules produced by Technofilter have clear labeling, representing the following information:

  • Grade (Filter type)
  • Pore size (micron rating)
  • Capsule number
  • DataMatrix -code, duplicating this information

Labeling enables identifying each Capsule accurately and correctly. It makes it possible to trace each item throughout the whole production process, thus enhancing general production safety.

While reading information by means of barcode scanner it is possible to automatize data input on-site in process data base. Moreover, while working with integrity testers, for example Technocheck-3, it is possible to transform information about Capsule in respective information fields of the device memory automatically.
