What is a Flow Cell?

Feb 26, 2017 | Glossary of Spectroscopy Terms, Sampling

Flow cells are sample cells designed so that liquid samples can be continuously flowed through the beam path. This is useful for samples that can be damaged by the light source. New sample is continually replenished so that the damage does not interfere with the...

What is a Dip Probe?

Feb 26, 2017 | Glossary of Spectroscopy Terms, Sampling

Dip probes are a probe that allows you to perform liquid absorbance and transmittance measurements without a cuvette. The probe is dipped straight in the liquid sample and the measurement happens at the gap in the tip. A fiber delivers the light source to the tip and...

What is a cuvette?

Feb 26, 2017 | Glossary of Spectroscopy Terms, Sampling

A cuvette is a type of sample holder for liquid samples. Often, they are made of plastic, borosilicate glass, or quartz. StellarNet offers glass cuvettes for experiments in the visible or NIR ranges and quartz cuvettes for experiments in the UV range. Cuvettes also...
