Pall® Minimate™ Tangential Flow Filtration Systems

Minimate™ Streamlines Laboratory-Scale Concentration, Desalting, and Buffer Exchange Processes

Plug-n-play design. Plug in a Minimate™ TFF capsule, add sample, and turn on the pump to start processing. The Minimate™ TFF system includes all the hardware, tubing, and fittings needed to get your TFF process up and running quickly.

High concentration factors. The low system working volume achieved through the use of a conical bottom reservoir and compact design enables high concentration factors from up to 1 L or more of sample to be achieved. Concentrate your sample down to as little as 5 mL.

All wetted components are made from low protein binding, chemically resistant, biologically safe materials.

Minimal sample carryover. The system has a very low volume and interior fluid contact area. Fluid does not pass through and is not retained in the pump mechanism.

Roller head peristaltic pumps provide gentle processing and are the choice for critical applications such as fragile biomolecules.

System components are designed for easy assembly and disassembly; no tools required. Tubing and fitting replacement is simple and quick. Slip nuts for luer locks eliminate tubing kinks.

for Nucleic Acid Binding

Pall® AcroPrep™ Advance 96-well for Nucleic Acid Binding

The Pall AcroPrep Advance 96-well Long Tip Filter Plate for Nucleic Acid Binding (Pall NAB plate) incorporates a silica-based quartz glass fiber media to allow for efficient binding of DNA and RNA, while providing smooth flow and rapid processing of samples. This media offers researchers the flexibility to purify plasmid DNA from bacteria, and genomic DNA or total RNA from cell culture samples: a single plate for multiple applications. Reducing the chance of cross contamination is critical for reproducible quality results. Pall's new long tip plate minimizes hanging drop formation thus reducing the possibility of cross contamination. The Pall NAB plate is a multipurpose plate providing flexibility in applications, reduced risk of cross contamination and smooth flow for sample processing.

  • Maximum yields and quality of nucleic acid purification
  • New outlet tip geometry provides direct flow of samples into receiver plate without concerns of cross contamination
  • Silica-based quartz glass fiber media that allows efficient binding of DNA and RNA, while providing smooth flow and rapid processing of samples
  • Manufactured in accordance with specifications for the Society of Biomolecular Screening (ANSI/SBS x-2004) for multi-well plates allowing entire DNA purification process to be performed on automated equipment

ReadyStrain II Sterile Cell Straining Kits


ReadyStrain II™ is the only product of its kind, providing all necessary parts for filtration of cell suspensions and combining them into a single, preassembled, ready to use, sterile packet. These kits eliminate the contamination risks associated with opening multiple packages and assembling separate pieces (i.e. tubes, strainers and caps). The individual sterile packets mean researchers are no longer forced to expose entire bags of 50 mL tubes and caps in order to perform one filtration. Instead, they can open a single packet directly under the hood.

Each kit contains a sterile SureStrain™ Strainer, pre-attached to a sterile 50 mL tube, with a separate sterile screw-cap ready for assembly, processing and storage after the filtration is complete. Kits are supplied in easy open “tear-strip” bags and gamma sterilized.
  • Includes strainer, 50 mL tube & cap
  • Opens directly under the hood reduces contamination risks
  • Preassembled – ready to use
  • Guaranteed sterile – gamma
  • Packaged in easy-open “tear-strip” bags
