The Bausch & Lomb minispec 20 provides a new dimension in spectrophotometric analysis. Compact, lightweight and rugged enough to be used under adverse field conditions, it features a built-in rechargeable power supply for portable field analysis away from conventional power sources. The precision optical and electronic systems display the Bausch & Lomb tradition of excellence, and the instrument is equipped with the same type of high quality diffraction grating and monochromator as used in the popular Spectronic 20.

Unit comes with: field carry case, lamp, 115VAC 50/60 Hz battery charger, small parts storage box, adapter and insert for 1/2" test tubes and 1/2" vials., 1/2" vials with covers (qty:8), 25mm long path cells with covers (qty:2) and operators manual.
