Vernier sells two versions of the Starna Quartz cuvettes. They both are heat-fused, using no adhesive.
Quartz Cuvettes (CUV-QUARTZ)
These are standard rectangular cuvettes.
They are Far UV Quartz with a spectral range from 170 - 2700 nm. ...
If your spectrometer isn’t calibrating or is showing unusually noisy or high absorbance values (often above 3 or blank), the issue may be due to insufficient light reaching the detector. This happens when:
The light source is weak in a certain...
Sometimes the counts from the light striking a pixel is not sufficiently different from the counts when the pixel is in the dark to make a reliable absorbance reading. This can happen either when the light source is weak in that spectral region, or w...

The Vernier UVA and UVB Sensors respond to specific regions of the electromagnetic spectrum. The wavelength region from 320 to 400 nm is commonly called UVA radiation, and 280 to 320 nm is called UVB radiation. Wavelengths shorter than 280 nm fall in...
The UV Index (or UVI) was originally created as a predictive tool for the public to get a sense as to how intense the UV rays from sunlight will be. The US National Weather Service model takes into account the predicted filtering from the ozone layer...
A mini UV Lamp can be purchased from Wards Natural Science, wardsci.com. The lightweight unit contains a six-inch tube that emits 365 nm longwave UV. It is composed on high-impact plastic and has an attached lanyard for easy handling. Four AA batter...
