Key Features

    • Separates a maximum 1200 samples in as little as 15 minutes in 4 stacked gel trays
    • Double-sided 1.5mm thick combs allow more sample volume to be loaded into each well
    • Three gel tray options available in 8×6, 8×12 and 8x18cm (WxL) sizes for maximum flexibility
    • Multichannel pipette compatible combs for speed loading
    • Electrical Safety – lid can be located in one way only. On removal, power is disconnected from buffer chamber

For those planning to purchase multiple items for specific projects or techniques, Biocom Packages combine convenience with excellent value. 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.

The multiSUB series of Horizontal Gel Units offers the most versatile solution for DNA and RNA agarose gel electrophoresis currently available. All five units offer an unsurpassed combination of economy of gel and buffer volume, with gel size and sample number versatility. Gel size and sample number requirements can be exactly matched in each unit, with the option of additional gel tray sizes. This eliminates the need for multiple gel tanks for changes in gel size or application.
All units feature removable UV transparent trays. For optimum value and versatility, systems are available with one, two or three tray options (dependent on model). Easy to use, leak proof ‘plug and go’ gel casting dams are included as standard to allow gels to be rapidly cast whilst the multiSUB unit is in use for gel running. With no indentations or casting gate grooves in the tray to interfere with sample progression, traditional tape casting can be used, should this be preferred.
Although lid connectors are compatible with most major power supplies, adapters are available to provide complete compatibility.

POWERPOINT MIDI Programmable Power Supplies  are high performance, easy to operate instruments which represent excellent value. This inexpensive, compact POWERPOINT MIDI power supply is ideal for routine horizontal and mini vertical electrophoresis. Microprocessor control allows the unit to be set-up to run in constant voltage and constant current modes. Four gel chambers can be connected at any one time. A timer with alarm and pause functions can be set to end of run. Safety features include shrouded plugs and sockets, no load detection and ground leakage detection.
