667-UV19 Acetone liquid filter to check stray light at 325nm
The acetone liquid filter consists of pure acetone. This filter is suited to check the stray light of a spectrometer in the spectral range between 250 nm and 320 nm, its cut off is at about 325 nm.
Currently the usage of acetone stray-light filters to determine the stray light in the spectral range from 250 to 320 nm is only required by the United States Pharmacopoeia (USP).
