Biolab single beam visible spectrophotometers offers measurement range of 320-1100 nm at bandwidth of 4nm; which provides high accuracy, reproducibility and high throughput at each run. These lvs-100 series are inbuilt with highly durable tungsten halogen lamp, which best suitable for: for measurement of dna, rna and oligonucleotide and protein proteins can be quantitated by bca, biuret, bradford, direct uv and lowry the od of bacterial cell culture solutions can be measured to optimize harvest times for the determination of metal and organic non-metal analytes in water ideal to be use in petrochemical labs as they are solvent resistant such as naphthalene in aviation basic specification : wavelength range: 320-1000 nmwavelength accuracy: 2 nmwavelength repeatability: 1 nmspectral bandwidth: 4 nmstability: 0.002 ahr at 500 nm, 0 a
