UV–vis spectrophotometer
Shimadzu Scientific Instruments' BioSpec-nano UV–vis spectrophotometer is designed for the quantitation of nucleic acids. The instrument reportedly requires a sample volume of 1 μL, for a pathlength of 0.2 mm, or 2 μL, for a pathlength of 0.7 mm. The sample is pipetted onto the instrument's measurement plate. According to the company, sample measurement time is 3 s. The instrument includes dedicated software for operational functions. Shimadzu Scientific Instruments, Columbia, MD;

Spectrophotometer sample compartment
A large-sample compartment from Hitachi is available for the company's model U-3900 and U-3900H research-grade UV–vis spectrophotometers. The sample compartment accessory adds the capability for the reflectance and transmission measurement of solid samples. The unit reportedly is stackable on top of the spectrophotometer system and can be used with specular reflectance accessories. According to the company, the compartment accommodates samples as large as 120 mm in diameter for transmission and 50 mm in diameter for reflectance.
