Spectrophotometers & Fluorometers

Spectrophotometers and fluorometers measure the absorbance, transmittance, and fluorescence of samples for quantification of nucleic acids, proteins, enzymes, and small molecules. mLab Supply sources new, refurbished, and surplus UV-Vis spectrophotometers, microvolume instruments, and fluorometers from leading manufacturers.Related Detection Equipment Microplate Readers - High-throughput absorbance and fluorescence detection in 96/384-well format Analytical Balances - Gravimetric sample preparation for spectrophotometric assays Common Use Cases Nucleic acid quantification (DNA, RNA, oligonucleotides) Protein quantification (BCA, Bradford, A280) Enzyme kinetics and activity assays Cell density measurement (OD600) Fluorescence-based assays and dye quantification What to Look For Wavelength range: Standard UV-Vis covers 190-1100 nm; confirm range for your application Sample volume: Microvolume instruments (NanoDrop-style) require as little as 1-2 µL; cuvette-based units require 500 µL+ Scanning vs. fixed wavelength: Scanning instruments offer full spectrum analysis; fixed-wavelength units are faster for routine measurements Fluorescence capability: Dedicated fluorometers offer higher sensitivity than UV-Vis instruments with fluorescence modules Brands We SourceThermo Fisher (NanoDrop, GENESYS) | Agilent (Cary series) | Shimadzu (UV-1900) | BioTek | DeNovix | Horiba (FluoroMax)Condition Options New (select models available to source) Refurbished / Pre-Owned - lamp and detector verified, wavelength accuracy confirmed Surplus / As-Is - priced accordingly Availability and pricing are subject to change.
