Easy to assemble; no tools required, yet the stand was sturdy.
This was the only solution in the price range we have identified that delivers 352nm.
Great pre-sale and post-sale support from Lou!
Inexpensive compared to Fisher, VWR, etc. Works really well! Wonderful to be able to cut bands without having to wear goggles. Definitely recommend!
The model UVGL-58 Ultraviolet Lamp combines both short (254nm) and longwave (365nm) UV light in one handheld lamp with six watts of power for each separate UV tube. The lamp has dual switches for either long or short-wave use. The lamp's housing is durable, lightweight plastic that should last a long time. The lamp may be used for mineralogy identification, chromatography, document examination, and germicidal applications. However, this lamp is tethered to 120 volts AC from a standard wall receptacle and will not work with an automobile electrical inverter for fieldwork.
The lamp is also relatively expensive compared to other UV lamps in the same category. It would have been helpful if UVP had included directions with the lamp for removing the UV tubes and filter. An included booklet with online references that explains how the lamp may be used for specific mineral identification in the field would be helpful for the novice prospector.
Lithium is a strategic metal in high demand with limited distribution, and a field test using the UV lamp for identification would seem reasonable. Perhaps a modification of the UV spot test for the Lithium-ion below would be attainable

I was looking for an alternative to UV light for the visualization of eGFP in our laboratory to select transformed clones without causing DNA damage within the cells typically caused by UV. The UltraSlim has been working perfectly for my research and education needs since we purchased it in early September. In both the lab and in my undergraduate teaching laboratories it has been offering a viable alternative to a UV transilluminator.
The UltraSlim fits perfectly 2 standard Petri plates (100 x 15 mm) in its viewing zone at a time and the swivel amber filter allows us to circle transformed colonies with ease. Also, since eGFP excitation and emission is at 488 nm and 509 nm, respectively, this blue light illuminator is a great visualization for tool for eGFP since it illuminates at 470 nm, and the amber filter has a range of 500-590 nm (I wrote to the company before purchasing to find the filter range).
I sent the company a photo of an eGFP transformant plate of E. coli which I hope they’ll place on the website so you can see how the colonies appear. The eGFP transformants appear as a bright amber color under the filter whilst non-transformants appear more pale in color (so it’s easy to discern them).
I’d highly recommend the device for those using eGFP transformants and are concerned about DNA damage to transformants in research, or those looking for an alternative to the use of UV masks in undergraduate teaching labs.
