Ideal for use on solvent waste bottles 
Use on glass and plastic containers 
Prevent overflow from HPLC reservoirs
“TELLI alerts you when a container is almost full, preventing hazardous chemical spills in the lab.”
Ideal for HPLC / LCMS
Prevent spills and accidents. Solvent bottles are continually receiving small volumes of waste, and lab techs cannot always keep an eye on the liquid levels. TELLI tells you when the container needs to be emptied.
Radio Technology
TELLI can easily see through dark glass and opaque plastic containers when the human eye cannot. Ideal for use on bottles, carboys and drums of all sizes.
No-Contact Device
There is no risk of cross-contamination or chemical exposure with TELLI. It affixes to the outside of the chemical waste container with an adjustable elastic band. Set it and forget it, until it talks to you!
