The ENDURO™ UV Transilluminators represent a great new imaging product true to ENDURO™ name. These UV transilluminators have been designed for rugged use and durability with exceptional performance. The use of UV Black Glass minimizes the striping effect seen on many UV transilluminators. This provides a more uniform background for gel imaging. Conventional UV shields leak some UV ( 8%), but the Enduro UV transilluminators allow no leakage.
