MEMCAST™
The MemCast™ automatic casting machine is ideal for the automated synthesis of flat sheet polymeric membranes. This state-of-the-art machine allows for the precise creation of membranes with varying thicknesses by applying a thin film of polymer solution.
After the immersion in a coagulation bath, this results in the formation of the final membrane via wet phase inversion. Whether you need self-standing film layers, or you prefer to cast on various substrates, MemCast™ offers the ultimate solution.

RotaMem
The RotaMem is designed for the automatic centrifugal potting of hollow fiber membranes into R&D modules using 2 composite 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.
Specifications:
| Compatibility | Designed for modules made from Tritan copolyester up to 150 mm in length and max. diameter 20 mm, with potting made of epoxy or polyurethane 2k resins |
| Chamber Dimensions | 170 mm x 176 mm x 93 mm |
| Capacity | Maximum weight of centrifugal plate with modules and glue distribution up to 500 g |
| Adjustable Rotational Speed | 300-1500 ± 5 rpm |
| Temperature Control Range |
Room Temperature to 50 °C ± 5 °C |
| Control Panel |
Set and monitor temperature, rotation speed and process duration with ease |
Key Features:
- Consistent potting quality
- 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.
- Precise temperature control and adjustable rotation speed
- 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.
- Programmable procedures and flexible data storage
- 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.
- Enhanced safety features
- 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.

Spider
The Spider is a high-throughput dead-end filtration module designed to revolutionize liquid filtration workflows. Capable of performing up to 8 or 16 simultaneous filtrations (depending on the model), the Spider drastically reduces experiment time while ensuring reliable and precise results.
Built from robust stainless steel, the instrument is compatible with both aqueous and non-aqueous feed solutions, making it a versatile and essential tool for modern membrane laboratories.
The Spider workflow is simple: membranes are placed inside the sample holder, the chamber is sealed, and the feed reservoir is filled with the selected solution. By applying the desired pressure, individual permeates are collected in separate bottles for analysis, while the remaining retentate can also be retrieved.
