SP-400-BIO Spectrophotometer The SP-400-BIO is a simple, low-cost, easy-to-use UV/Visible spectrophotometer dedicated for life science applications. It is compatible with a wide range of small volume cuvettes, making it ideal for measuring DNA and RNA samples. To make measurements quicker and easier, the SP-400-BIO has preprogrammed methods for the measurement of nucleic acid concentration and purity, protein assays and cell density. This spectrophotometer measures across a UV/Visible wavelength range of 198 to 800 nm with a narrow spectral bandwidth of 3 mm. The SP-400-BIO is covered by a 3...

SP-400-BIO Spectrophotometer Measurement Modes The nucleic acid measurement mode can be used to quantify the concentration and purity of dsDNA, ssDNA, RNA, and oligonucleotides using wavelengths recorded at 260, 280 and 230 nm, with an optional correction at 320 nm. The concentration is calculated along with the corresponding purity ratios 260/280 nm and 260/230 nm. At the touch of a button, it is easy to visually check the purity of the nucleic acids. This is done by identifying peak levels in the purity scan between 200 and 350 nm. This is especially useful for RNA samples where impurities...

SP-400-BIO Spectrophotometer USB Connectivity There are two USB ports for data storage and printer connectivity. The easy access USB port on the front of the instrument can be used to easily store results and transfer data as tab delimited text files to Microsoft® Excel®. Accessories The SP-400-BIO is supplied with a micro-cuvette holder as standard, making it ideal for small sample volumes down to 50 µL. For even smaller sample volumes, the SP-400-BIO has been designed to work with the Traycell and DMV-BioCell accessories. This enables ultramicro samples as low as 0.7 µL to be measured without...
