Known for their exceptional performance and durability, Spectroline® transilluminators are designed to deliver optimal UV intensity and extremely uniform UV emission to guarantee clear and reproducible results.
Spectroline transilluminators provide maximum fluorescent response for nanogram sensitivity with minimal UV damage to samples with a variety of choices in wavelength, wattage, filter size and variable intensity controls. Each unit offers high intensity, uniform UV emission and cool operation. They feature a wide variety of UV filter glass sizes to accommodate different sizes of gels and blots, as well as rugged construction and simple operation.
When working with UV models, attention should be given to the age of the UV tubes, as this will affect the sample fluorescent signals. As the UV tubes age in any transilluminator, their output steadily declines making faint bands more difficult to see. This can result in lack of positive results and incorrect densitometric measurements. Regular replacement of UV tubes is suggested, particularly for transilluminators that are shared or heavily used.

LONGLIFE™ UV Filter Glass
Inhibits solarization up to 50 times longer than traditional UV filters.
Easy-to-Clean, Rugged Housing
Composed of durable, stainless-steel filter frame welded to scratch-resistant painted metal
Powerful Cooling Fan
Maintains low filter glass temperature to eliminate surface heat buildup
Minimal UV Damage
312nm and 365nm models virtually eliminate transmission of 254nm radiation
Special Diffusing Screen (D)
Ensures superior surface uniformity by eliminating striations caused by the contours of the tubes; provided on all 312nm and 365nm models
Variable-Intensity Control (V)
Provides continuous intensity adjustments from 100% down to 20% for maximum sample preparation time and sensitivity
On/off Switch (S)
Controls power to the unit
Automatic Shut-Off Timer (T)
Prevents UV overexposure; doubles as on/off switch
Hinged UV-Blocking Cover (C)
Adjustable to a comfortable angle providing the end user with a clear view of surface access for sample manipulation. Eliminates the need for additional UV-absorbing clothing or face wear and protects the filter surface from accidental damage
