Jelight UVS-18

is a shortwave ultraviolet and white-light lamp designed for fluorescence inspection, laboratory examination, and applications requiring both 254 nm UV illumination and visible light. Equipped with one 8 watt 254 nm UV tube and one 8 watt white-light tube, the UVS-18 allows samples to be examined under shortwave ultraviolet excitation and normal visible illumination using a single durable EL Series lamp.

Applications

Fluorescence Inspection

Provides 254 nm shortwave UV excitation for observing fluorescent materials, stains, compounds, minerals, and other substances responsive to shortwave ultraviolet radiation.

Laboratory and Analytical Work

Suitable for sample examination, fluorescence observation, laboratory inspection, educational demonstrations, and analytical procedures requiring a dependable 254 nm ultraviolet source.

UV and Visible-Light Comparison

The integrated UV and white-light tubes allow specimens and work surfaces to be examined under shortwave UV excitation and normal visible illumination without changing lamps.

Hands-Free UV Inspection

Can be paired with a compatible lamp stand or UV viewing cabinet for stationary illumination during laboratory inspection, sample handling, and fluorescence observation.

FAQs

Does the UVS-18 produce both UV and white light?

Yes. The UVS-18 contains one 8 watt 254 nm ultraviolet tube and one 8 watt white-light tube, allowing samples to be viewed under either shortwave ultraviolet or visible illumination.

Can the UVS-18 be used hands-free?

Yes. The UVS-18 can be paired with the J-138 Lamp Stand, part number 18-0063-01, or used with a compatible UV viewing cabinet for stationary sample examination.

What safety measures should be taken when using the UVS-18?

Use appropriate UV-protective eyewear and face protection when operating the lamp, and minimize direct exposure of the eyes and skin to ultraviolet radiation. Shortwave 254 nm UV can cause eye and skin injury, so do not look directly at the UV source and avoid unnecessary exposure. Follow applicable laboratory, workplace, and site-specific UV safety procedures during operation.
