DI-Lamba UNO spectrophotometer

DI-Lambda UNO is a fixed-wavelength photometer designed for biochemical and environmental science assays. It’s a great fit for both a classroom and a research laboratory.

DI-Lambda can be used to measure bacterial growth (OD600), protein or glucose concentration in food samples, to characterize water parameters (chlorine, hardness, contamination with nitrites, copper, lead), and more.

For classroom use, we offer a range of experimental kits that were developed to work with DI-Lambda. Take a look.

For a research laboratory, DI-Lambda a great choice for simple routine measurements. Get one for your workbench, and you won’t have to walk to the fancy UV-IR spectrophotometer to take OD600 or measure protein concentration.

DI-Lambda UNO features a color LCD display, and can also be controlled from a computer. It is compatible with industry-standard square cuvettes.
