• Uniform Illumination | Four 302 nm Bulbs
• Adjustable UV Safety Cover | Easy Access to Gels
• Large Scratch Resistant Viewing | 16.5 x 13.5 cm

The E3100 Compact UV Transilluminator has a surprisingly small footprint (just over 12 x 8 In.) yet provides industry leading performance. It will accommodate one or two mini gels on the 16.5 x 13.5 cm scratch resistant viewing surface.

The integrated UV blocking cover is made from a polymer that will not fluoresce in UV light. This allows clear viewing of DNA bands through the cover yet offers full UV blocking protection. Two friction hinges on the front edge of the cover allow for full adjustment. Position the cover horizontally for general viewing, tilt it at an angle for gel access and band cutting, or open fully to use the SmartDoc™ Imaging Enclosure (sold separately) for gel imaging with a smartphone.

The transilluminator’s four 6W bulbs evenly illuminate the viewing surface, and the 302 nm wavelength is ideal for Ethidium Bromide, SmartGlow™, SYBR Green®, Gel Green™ and many other common gel stains.  Spacing of the UV bulbs, coupled with a reflector system and special diffusing filter glass provides exceptional uniformity across the viewing surface. This allows for quantification of DNA and higher quality imaging when used with a camera system.

Gel Crusher™ Spin Column

Rapid Gel Fragmentation for DNA Recovery.

Gel Crusher™ Spin Columns provide a fast, efficient, and consistent method for gel fragmentation, replacing traditional crush-and-soak or manual gel breaker steps. Designed with 600 uM filtration pores, these columns enable quick and uniform fragmentation of agarose or acrylamide gel slices, saving time and increasing DNA recovery yields.

Ideal for workflows in molecular cloning, PCR cleanup, restriction digests, DNA sequencing, and labeling protocols, the Gel Crusher™ simplifies the preparation of gel fragments for downstream purification and elution steps.

Simply insert the Gel Crusher™ column into a 2 mL microcentrifuge tube, add your pre-cut gel slice (prepared using a gel cutter or razor blade), and centrifuge at max speed (~15,000 x g) for 5 minutes. The gel will be forced through the 600 uM pores, producing small, uniform fragments that can be easily pipetted using wide-bore tips into NaCl or other solutions.

This process creates a fine slurry that enhances elution efficiency and improves access to the target nucleic acids, significantly reducing incubation and processing time.

Key Features

• Efficiently breaks gel slices into uniform fragments
• Eliminates manual crush-and-soak steps
• Increases DNA yield and recovery efficiency
• Fits standard 2 mL microcentrifuge tubes
• Compatible with standard benchtop centrifuges (up to 15,000 x g)
• 600 uM pore size ideal for agarose or acrylamide gels
• Simplifies downstream processes: elution, filtration, incubation
• For use in PCR, cloning, digestion, sequencing, and more 

Reversible Racks

• Choose 60 well (5 x 12) or 96 well (8 x 12) formats
• Reversible racks, accept 0.5 and 1.5 to 2.0 mL microtubes
• Alphanumeric marking on each well
• Made of polypropylene

Labnet™ 1001 Mini Plate Spinner Centrifuge

Compact Microplate Centrifuge for PCR and Microplate Samples.
