Sartocon® 2 plus, 1.4435/F/R23/P23, JIS-G

Sartocon® 2 plus - 1.4404 or 1.4435 - stainless steel holder is optimized for the use with up to ten Sartocon® or two Sartocube® production scale Crossflow cassettes (max. 7 m²). It is designed for applications from 30 L to 1000 L volume.

Item no.:  17546DJ230230

Availability (ex works):  On Request


The Sartocon® 2 plus holder is part of a modular micro- and ultrafiltration system and fits up to ten Sartocon® filter cassettes. A maximum filter area of 7 m² allows to process volumes of 30 to 1000 L. It is designed for process development and pilot scale production in pharmaceutical and biotechnology crossflow applications. Easy handling design and high quality materials make this the perfect tool. The Sartocon® filter cassettes are placed between the filter plate and the the clamping plate without a need for additional gaskets. It is not even necessary to remove the clamping plate for installation of the cassettes. Just place the cassettes on the guide rods and close the holder by turning two nuts with a torque wrench. This vertical positioning of the cassettes allows self draining of retentate and permeate channels during harvesting and steaming processes. Thermal sterilisation in an autoclave or steaming in place even with cassettes installed is possible. For this purpose the installation of a pressure compensation tool is necessary. Filter plate and sanitary flanges are made out of one single piece of steel. The whole holder is designed without a weld. This ensures a perfect fit of additional equipment like manifolds and valves.

Hydrosart® Microfilter

Hydrosart® membranes are extremely hydrophilic, making it non-protein binding and virtually non-fouling. Hydrosart® mikrofiltration cassettes are available in 0.2 µm and 0.45 µm.

Hydrosart® Ultrafilter

Hydrosart® high performance membrane is a stabilized cellulose based membrane that has been optimized for biopharmaceutical process applications. Hydrosart® is stable across a broad pH range, is extremely hydrophilic, making it non-protein binding, and virtually non-fouling. Membrane cleaning, storage and depyrogenation can be accomplished by using NaOH even at elevated temperatures and concentrations. These features make Hydrosart® an ideal membrane for biological applications.

Polyethersulfone Microfilter

PESU cassettes are available in 0.1 µm pore size. Polyethersulfone membranes are designed for applications in the biotechnological and pharmaceutical industries. They can be used to remove the following cells from liquids:

  • Mammalian cells
  • Clostridia
  • Yeasts
  • Salmonella
  • Mycoplasma reduction

Polyethersulfone Ultrafilter

Polyethersulfone membranes (PESU) are stable polymer that feature a broad pH and temperature range. Polyethersulfone ultrafiltration cassettes are available in the following nominal molecular weight cutoffs:

  • 1 kD
  • 5 kD
  • 8 kD
  • 10 kD
  • 30 kD
  • 50 kD
  • 100 kD
  • 300 kD
