Transilluminator - Ultra Violet and White Light
Transilluminator for Electrophoresis Gels
Gel viewing EtBr transilluminator Transilluminator White light

Zenith transilluminators feature special glass filters that block all visible light and only pass ultraviolet rays of the designated wavelength. This ensures clear and distinct observation of gels placed on the transilluminator, with nearly no visible light.

The top of the transilluminator is made from brushed stainless steel, that's easy to clean and rust-proof.




Gel-VU transilluminators are now CE marked and made in an ISO9001:2008 certified facility.
These are high quality products, proudly made in India.
Comparison

Comparison of sensitivity of UV transilluminator

A comparison was done between the performance of our transilluminator and a European transilluminator. The same EtBr-stained gel was viewed and photographed in our transilluminator and then immediately again (so that the lighter bands did not diffuse) on a famous European-brand transilluminator. The camera settings were the same and transilluminators intensity set at maximum in both transilluminators. Post processing involved cropping & pasting the gel images together and the text annotations shown in image above. No processing was done to deliberately lighten the bands in the European-brand transilluminator. This comparison was done at a large biotech company in Bangalore (India) that had access to both our and the other transilluminator.

Clearly, our transilluminators perform better than the European brand despite being much less in price.

Features


- Long life UV quartz filter
- Special polymer filter mounted on hinges to block UV rays from harming the observer
- Transilluminator window sizes: 10 x 10 cm, 20 x 20 cm, 21 x 26 cm
- Electronic ballast ensures no humming and low heating of transilluminator
- Intensity control provided: 70% and 100%
- Transilluminator models also available without filter for low cost, student work

Advantages
