For those planning to purchase multiple items for specific projects or techniques, Biocom Packages combine convenience with excellent value. The MultiSUB Choice offers a wide degree of versatility. Three tray options are available; 15 x 7cm, 15 x 10cm and 15 x 15cm – allowing the choice of one, two or all three gel length options at the time of purchase. Further purchases of additional accessories are no longer required. Maximising comb and tray options allow up to 210 samples to be resolved per gel. The 15cm total run length allows restriction fragment or other close MW sample bands to be easily separated and identified. Speed loading is accomplished using 10, 14, 16, 18, 28 or 30 sample multi-channel pipette compatible combs. All models include loading guides and casting dams. MultiSUB Choice Trio includes all 3 tray sizes for optimum versatility and value.

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 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.
