The frame is designed to be fitted with up to 24 individual Vivaspin500 ultrafiltration devices, also supplied by Vivascience. The vertical membrane design and built in dead stop pocket inherent to all Vivaspin devices allow fast and safe high throughput concentration of 24 samples per plate. In this format 500µl samples can be concentrated 30 times in just 15 minutes.
The 24-well ultrafiltration frame and the supplied collection plates have the dimensions of standard microtiter plates and are compatible with swing-out rotors for spinning deep well plates, allowing simultaneous processing of 96 samples (four plates).
The keyed fittings in the ultrafiltration frame for both Vivaspins and the receiver plate ideally suit the resulting 24-well plate for automated liquid handlers and sample stacking.
Vivaspin500 ultrafiltration devices have a wide membrane cut off range from 3kDa to 0.2µ. The flexible frame format allows using devices with different molecular weight cut offs in the individual wells for optimised processing of different sample types in parallel.
