• Membrane MWCO (Daltons): 10,000 Daltons
• Manufacturer number: NP 74-0903
• Model: NP 74-0903
• Part Number: AO-02892-86
• Package Quantity: EACH

These 96-well dialyzers let you simultaneously prepare 96 samples. Use for applications such as salt removal, buffer exchange, parallel sample prep after fraction collection, detergent removal, HPLC, and more. Each well contains an individual, high-quality, regenerated cellulose membrane that eliminates sample contamination and leakage. Membranes are free from sulfur and heavy metal contamination. Wells are sealed with 8-cap strips (included). To use the dialyzer, simply place the sample into each well and assemble the strip caps. Float the entire plate in dialysis buffer. Then, retrieve the purified samples for downstream applications. What's included: twelve 8-cap strips to seal wells.

Spectra/Por Float-A-Lyzer G2 Dialysis Device, 8000 to 10,000 MWCO, 5 mL Sample Volume; pack of 12 Reviews

Other Picture

Spectra/Por Float-A-Lyzer G2 Dialysis Device, 8000 to 10,000 MWCO, 5 mL Sample Volume; pack of 12 Feature

• Spectra/Por Float-A-Lyzer G2 Dialysis Tubes
• Disposable ready-to-use dialysis device eases sample loading and retrieval
• 95 to 98% sample recovery, 99% sample purity and <10% sample dilution
• Leak-proof screw cap allows easy pipette access for sample loading, testing, and retrieval
• Ideal for dialyzing electro-eluted proteins and chromatography fractions
• Product Type: Dialysis Tubes
• Part Number: AO-02906-33
• Package Quantity: PACKAGE

The Float-A-Lyzer G2 features biotech grade cellulose ester (CE) membrane. The low protein-binding, ultrapure membrane (no heavy metals and sulfides) is available in nine precise MWCO''s from 100 to 1,000,000 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 pipette. The included floatation ring and weighted bottom maintain vertical orientation during dialysis. This design also permits several units to fit in a single reservoir. All sizes are supplied dry with glycerol in a package of 12.
