• 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.

Hoefer® Semi-Dry Transfer Units

Hoefer® Semi-Dry Transfer Units are efficiently designed to use minimal buffer to transfer proteins from polyacrylamide gels onto membranes (either nitrocellulose or PVDF) in less than an hour. They support as many as two layers of gels being transferred simultaneously. The TE70XP has a 14 x 16 cm maximum transfer area, which can handle up to four mini gels using the stacked format. The TE77X and TE77XP have a 21 x 26 cm transfer area for a capacity of up to 12 mini gels at one time. 

• Included safety circuit breaker—limits voltage and current from the user's power supply, preventing electrical damage to the transfer unit
• Requires minimal current—does not generate the excessive heat that can dry out the transfer stack and halt transfer or damage transfer units 
• Durable iridium oxide and stainless steel electrodes—allow for contamination free, consistent transfer
• Vented electrodes—prevent buildup of bubbles which may impair transfer
• Minimal buffer requirements—reagent cost and preparation time are reduced
• The TE70XP and TE77XP Semi-Dry Transfer Units have an intelligent built-in power supply that prevents the stack from overheating by monitoring the transfer status
