Clean and in excellent condition. From a complete system, pulled out of a premier state facility. This system was well maintained, with the most recent PM in 2025. Computer systems were not included as is standard under HIPAA regulation.

This system comes only as shown in photos. Without accessory components, software and computers, we were unable to independently test.


Manufacturer Description

OLIS RSM 1000
Millisecond scanning with milliabsorbance sensitivity

Developed for stopped-flow spectroscopy, the “RSM 1000” identifies “Rapid-Scanning Monochromator” capturing
“1000 scans/ second.” The name used on the 1992 patent is “Subtractive Double Grating Monochromator with
Moving Intermediate Slit." Every OLIS product with the numeral “1000” includes this singular performance:
milliabsorbance sensitivity with millisecond scan rates. In addition, when used in single wavelength mode, the
acquisition rate becomes 1000 points per 2 milliseconds, perfect for laser/ flash photolysis
