Superior Performance
Unsurpassed UV intensity and outstanding irradiance uniformity
clearly show what others may miss—even trace amounts of DNA!

LONGLIFE™ Filter Glass
Inhibits solarization up to 50 times longer than conventional filters,
extending filter life and saving you money!

Powerful Cooling Fan
Maintains low filter glass temperature to eliminate decreased intensity and sample-damaging surface heat buildup.

Special Diffusing Screen
Provides unmatched irradiance uniformity. All of our 312nm and
365nm models are equipped with a removable, polymer-based diffusing screen attached below the filter that ensures superior light distribution and eliminates confusing light striations caused by the contours of the tubes (see photos below).

Longest Sample Preparation Time and Maximum Sensitivity!
For maximum sample protection during the preparation stage,
Spectroline TV-series variable-intensity UV transilluminators are
continuously adjustable anywhere from 100% all the way down to
20% (50% in the case of TVD-1000R dual-light transilluminator). They can then be raised to whatever level is needed for the clearest analysis.

Smooth, Easy-to-Clean Filter Frames
Reduce the chance of gel damage or contamination.

Automatic Shut-Off Timers
Prevent UV overexposure (Standard TC- and TL-Series only, Select Series units do not contain timers).

Minimize Photodamage
Spectroline 312nm transilluminators virtually eliminate transmission of destructive 254nm radiation, so there is minimal photobleaching, photonicking and photodimerization. Since your samples last much longer, your testing becomes a lot faster and easier.
