Centrifugal Filters

Supplier: VWR International

Use to: Concentrate, purify, and desalt peptides, proteins, oligonucleotides, DNA, and RNA; clean up labeling and PCR reactions; isolate DNA from agarose gel slices; buffer exchange; separate proteins, oligonucleotides, and RNA from acrylamide gels; clarify samples; or remove particulates.

Supplier: Cytiva

Precise, quick recovery of microliter volumes of concentrate from starting volumes up to 5.0 ml.

Supplier: Cytiva

Simple, reliable processing samples of 50 to 500 μl.

Supplier: Cytiva

Convenient and reliable concentration, purification, and diafiltration of 15 to 60 ml biological samples.

Supplier: Cytiva

NAB Nanosep® is a low cost alternative to expensive kits that yields quantity and quality of nucleic acid suitable for downstream applications, such as PCR, sequencing, and RE digestion. NAB nanoseps offer various protocols that help the end user save money without sacrificing results.

Supplier: Cytiva

These centrifugal devices can quickly concentrate up to 20 ml of biological sample without valuable sample loss.

Supplier: Sartorius

These are for 0.1 to 1000 ml, Hydrosart® membrane. Vivaflow 50R is a ready to use and reusable laboratory crossflow cassette for applications like cell culture supernatant concentration, virus concentration and water sample concentration. The thin channel, flip flow recirculation path of the modules provides high crossflow velocities with minimum pump speed requirements. A single module with 50 cm² active membrane area typically concentrates 250 ml by a factor of 20 in less than 30 min.

Supplier: Thermo Scientific

These Glutathione spin columns provide a fast, easy-to-use format to purify GST-fusion proteins from cellular lysates.

Supplier: Sartorius

Vivacon® 2 centrifugal concentrators have been designed for DNA concentration, buffer exchange applications and primer removal.

Supplier: Sartorius

Vivaspin® concentrators are disposable ultrafiltration devices for the concentration of biological samples of 0.4 to 2 ml.

Supplier: Epredia

Prepare larger volume samples conveniently with the Epredia™ EZ Megafunnel with caps and slides.

Supplier: Sartorius

LentiSELECT kits offer LentiSELECT 40, LentiSELECT 500 and LentiSELECT 1000 for the purification and concentration of VSV-G pseudotyped lentivirus from 40 to 1000 ml cell culture, leading to purified infective particles. These lentivirus purification and concentration kits offer purified recombinant lentivirus particles for in-vitro transfection a fast, safe and easy to use solution. These kits replace time-consuming ultracentrifugation protocols, which typically take about one day for large sample volumes, thus reducing the purification time to only a few hours.

Supplier: Corning

These non sterile centrifugal concentrators offer a simple, one step procedure for concentrating or desalting proteins and other biomolecules with 90% or better recovery.

Supplier: Thermo Scientific

Protein Concentrators PES are disposable ultrafiltration centrifugal devices with a polyethersulfone (PES) membrane for concentration, desalting, and buffer exchange of biological samples such as proteins and nucleic acids.

Supplier: Sartorius

Vivaspin® 6 centrifugal concentrators have been developed to offer increased volume flexibility and performance. Vivaspin® 6 can process 6 ml in either swing bucket or fixed angle rotors accepting standard 15 ml conical bottom test tubes.

Supplier: Sartorius

Vivacell® 100 is a disposable ultrafiltration unit for the concentration of samples up to 98 ml that can be used either in a centrifuge or for pressure filtration.
