Micro Float-A-Lyzer 3.5-5.0 kDalton, 400-500L

Disposable ready-to-use dialysis device for micro-analysis|98% sample recovery|Leak-proof luer-lok cap for sample protection|Available in 2 volume sizes|The Micro Float-A-Lyzer features ultrapure biotech grade cellulose ester (CE) membrane. The low protein-binding, ultrapure membrane (no heavy metals and sulfides) is available in seven precise MWCO's from 100 to 100,000 Daltons. The color-coded, re-sealable screw cap eliminates leaks associated with knots, closures, and needle punctures and allows repeated access for in-process testing. The cylindrical tubing geometry prevents sample dilution and provides open access for total volume retrieval with included syringe. The sample device is self-floating due to an air bladder to maintain vertical orientation during dialysis; the sample device is also self standing for easy sample loading and retrieval. Individual units have interlocking housing for multi-sample dialysis. All sizes are supplied dry with glycerol in a package of 12.
