ultrassay™ Micro-spectrophotometer is a high-end precise analytical instrument, which is often used for protein quantification and quantification of bacterial growth concentration. ultrassay™ Micro-spectrophotometer is an instrument that uses spectrophotometry/fluorescence for quantitative and qualitative analysis of substances. It is often used for the quantification of nucleic acid, protein quantification, and bacterial growth concentration. ultrassay™ Micro-spectrophotometer has become a routine instrument in a modern molecular biology laboratory. Nucleic acid quantification is the most frequently used function of the Micro-spectrophotometer. It can quantify oligonucleotides, single-stranded, double-stranded DNA, and RNA dissolved in buffer.
