VS20 WAVE Maxi

The new VS20 ‘WAVE’ Maxi System is our latest product innovation for large format
vertical gel electrophoresis. Designed to perform a variety of separations, including firstand
second-dimension SDS-PAGE, native, preparative, gradient and high-resolution nucleic
acid electrophoresis, plus capillary tube gel IEF and electroblotting, the VS20 WAVE is one of
the most versatile maxi vertical systems available.
By introducing innovative, new vertical screw-clamp technology within the PAGE insert only
four screws are now necessary to secure as many 20x20cm gels. This gives the VS20 WAVE
Maxi the selective advantage of a much faster set up speed compared to competitor products
whose traditional clamping configurations require as many as 24 screws to secure just two
glass plates. In addition, the WAVE’s vertical screw-clamp configuration distributes pressure
evenly along the height of the gel rather than in the centre to eliminate plate bowing and gel
compression, but still maintains a leak-proof seal during casting; while the ergonomic wave-like
design of the PAGE insert aids both handling and set up.
Whatever your requirements are the WAVE can be made to meet them. Regardless of whether
it is running 2 or 4 gels, electroblotting, and IEF using capillary tube gels or IPG strips, all of
these techniques may be performed using the same omni-purpose unit while retaining the
benefits of large format electrophoresis, such as extended separation distances, greater sample
throughput and superior resolution.
Versatility and Adaptability

• More Gels – run 2-4 gels simultaneously in standard 2-gel WAVE and 4-gel WAVE TETRAD
systems
• Customise your system – for second-dimension runs with 18cm IPG strips and gels using
the IEF conversion kit
• Utilise modular inserts – with the same universal tank and lid to extend the application of
your standard WAVE unit to create a complete 2-D or blotting system:
• WAVEC2DS with capillary tube gel insert for 2-D electrophoresis
• WAVECBS and WAVETETRAD-CBS for 2- and 4-gel electroblotting
Reproducible Separations
• Vertical screw-clamps distribute pressure evenly along the height of the gel to prevent plate
bowing and gel compression
• Glass plates compress gently against a flat, level gasket to prevent current leakage from the
inner buffer chamber during electrophoresis
• Detachable inner cooling coil connects to the laboratory water supply or a recirculating
chiller to provide uniform, smile-free electrophoresis, while allowing runs to be performed at
higher voltage
• Deep gel tank with adequate clearance beneath the glass plates to allow a magnetic stirrer
to maintain buffer recirculation and uniform pH.
Casting Advantages

• Dual purpose PAGE insert eliminates time-consuming transfer of glass plates between
separate casting and running modules
• Ground glass plates with bonded injection moulded spacers consistent with comb thickness
ensure ‘clean’ well formation, as well as the correct alignment for leak-free casting; also
eliminate the need for easily mislaid and awkward to use spacer aligners
• Very forgiving, ultra-soft silicone mat within cam-caster compensates for glass plate
misalignment to ensure leak-free casting
Other Benefits
• Notched glass plates with bonded spacers supplied with WAVETETRAD systems allow gel
capacity to be doubled from 2 to 4, while dummy plate allows single gels to be run
• Bonded spacers and combs colour coded for thickness
• Widest selection of combs allow separation of up to 192 samples
• Robust 4-mm-thick glass plates
• Asymmetric lid design and colour-coded screw pins in PAGE insert prevent polarity reversal
• All parts injection moulded using durable industrial-grade plastic to guarantee longevity and
reliable and consistent performance
