RotaMem - reproducible potting of filtration mini modules

Rotamem

The RotaMem is designed for the automatic centrifugal potting of hollow fiber membranes into R&D modules using 2 component potting glue. The process starts by placing two modules, containing the hollow fibers, together with the casting container together with the dosing system, into a holder. This module holder is then positioned on a rotor in the drawer that slides out from the centrifuge. The process can start when the drawer with modules and casting container is slid into the potting chamber.

Upon starting the selected fabrication program, the module begins to rotate and the potting chamber is heated to the required process temperature. As the centrifuge reaches the specified parameters, polyurethane or epoxy resin is introduced into the casting container through a central opening in the centrifuge lid. The centrifugal forces generated cause the resin to flow from the casting container into the head area of the modules. Once the resin hardens, the centrifugal plate stops rotating, allowing the modules to be removed from the potting chamber.

Key features

01
Consistent potting quality
Membranes close-up

The uniform glue distribution ensures a sharp, reproducible border between the potting block and the active part of the hollow fiber bundle, preventing capillary rising of glue along the fibers. This guarantees that all fibers are evenly glued, while also ensuring better thickness control.

RotaMem control screen

The RotaMem maintains precise temperature control to ensure reliable and consistent results. The rotation speed is also adjustable, allowing you to tailor it for optimal potting conditions.

RotaMem USB input

Create and store multiple procedures for time, temperature, and rotation speed. Additionally, process data can be exported to a USB stick for analysis and quality control.

The RotaMem is equipped with process control features to ensure safe operation. The inspection lid with glue dispensing window allows easy access for inspection and precise glue application. Visible alarms provide clear notifications when set points are reached.

Consumables

RotaMem consumables
The module housings and dosing system can be ordered separately. A set consists of 20 module housings (150 mm x 20 mm) with potting caps and one glue dosing system.

One dosing system is sufficient for 20 modules (10 runs).
