Product Description

multiSUB-4 is a compact system capable of running over 1200 samples simultaneously by stacking up to 4 horizontal gels. This achieves high sample throughput while maintaining the advantages of a small and compact unit.
Each multiSUB-4 is supplied with 4 gel trays and 8 combs as standard. Two double-sided comb and three tray length formats, 8×6, 8×12 and 8x18cm are also available.
These multichannel-compatible combs and gel plate configurations are compatible with microplates and thermal cycler blocks to ensure rapid loading of DNA minipreps and PCR products by 8-channel pipette.
An optional Flexicaster allows up to four 8×6, 8×12 and 8x18cm multiSUB-4 gel trays to be cast simultaneously outside the tank.

Although lid connectors are compatible with most major power supplies, adapters are available to provide complete compatibility.
