Float-A-Lyzer-Holder

FLOAT-A-LYZER-HOLDER* - BIOPROCESSING with Dissolution Tester

The Float-A-Lyzer® from Repligen offers a unique, simple possibility - also in bioprocessing - to test liquid nanoparticle formulations, microparticle formulations and suspensions by reliably separating the released active ingredient from the carrier material by means of dialysis - ensuring, that the test gives accurate release rate results. The chart in the picture gallery shows that a large number of molecule sizes are ideally suited for dialysis and so there are for example possible applications like:

• Active ingredient release
• HPLC sample preparation
• Buffer change and desalination
• Nanoparticle and liposome preparation
• Separation and preparation of DNA, proteins, viruses, antibodies and peptides
• further applications can be found on the right under "Brochures"

The Float-A-Lyzer® is a unique, leak-proof and ready-to-use device and consists of a high-purity biotech cellulose ester (CE) membrane. The Float-A-Lyzer® is available in different lengths (for 1-10ml) and 9 different exclusion limits / "Cut-Offs" (NMWC / MWCO) from 0.1 - 1.0000kD. More information you find here or at www.repligen.com .

The Float-A-Lyzer® are available directly from us at low prices. A selection you can find here.

However, the Float-A-Lyzer® on its own is not ideal for all applications because it can swim around in the test vessel and is thus exposed to different, non-reproducible fluid dynamics. Therefore, the ideal addition to the Float-A-Lyzer® is to use a qualified dissolution tester and the Float-A-Lyzer® holder from QLA! The dissolution tester always offers reproducible and qualifiable fluid dynamics and temperatures. It can be fixed in the dissolution tester in two ways and thus deliver absolutely reproducible results.

1. With USP1 (basket method) for less fluid dynamics, also available for small volumes
2. With USP2 (paddle method) for more fluid dynamics around (requires vessel cover with hole for "Stationary Basket")

Further information and pictures can be found on the right under "More Information".
