Materials
Construction materials
The cartridge body can be manufactured in different engineering materials depending on the chemical compatibility required.
- Acrylic resin for standard laboratory use
- PEEK / PAEK for solvent-oriented workflows
- PPS for solvent-oriented workflows
PEEK, PAEK and PPS are recommended for OSN applications.
Rotor compatibility
Each CentrivaLab family is designed around a specific rotor angle and tube class. The cartridges drop into the rotor positions of standard fixed-angle centrifuges — no adapters required.
Rotor compatibility — 50/34
