NF / RO / OSN
CentrivaLab 94/25
Configuration prepared for larger working volumes and fixed-angle rotor classes around 25°. The 94 mL designation refers to the centrifuge tube (rotor bucket) capacity, not the feed volume.

Product detail
CentrivaLab cartridge
The cartridge houses a flat membrane disc (20 mm outer diameter, 1.45 cm² effective filtration area). After centrifugation, retentate and permeate are collected separately for analysis. The numbered cap system ensures sample tracking across parallel experiments.
Construction materials
Cartridge bodies are available in different engineering materials depending on the chemical compatibility required by the application.
Acrylic resin
Standard option for aqueous NF and RO applications. Suitable for most laboratory membrane screening workflows.
PEEK / PAEK
Recommended for organic solvent nanofiltration (OSN) applications requiring resistance to a broad range of organic solvents.
PPS
Alternative high-performance polymer for solvent-oriented workflows where PEEK/PAEK compatibility needs to be confirmed case by case.
