Description
EziLab offers the Micro Volume Spectrophotometer EZL-MS153, a UV spectrophotometer that reads nucleic acids at 260 nm and 280 nm from just 1–2 µl of sample. A fixed 0.5 mm path length covers an absorbance range of 0.02–80 A and a dsDNA range of 10–4000 ng/µl, with sensitivity down to 0.5 pg/µl and repeatability under 1.5%. Results appear in under 8 seconds with no lamp warm-up, and a UV silicon photocell detector sits in a test chamber that blocks stray light. Samples wipe off the open port between runs, so there is no carry-over. A 7-inch touchscreen runs the unit, data exports by USB, and an auto-off function cuts power after 5 idle minutes, drawing only 5 W on standby. For DNA quantification, the 260/280 ratio shows sample purity, so scientists can check DNA and RNA yield before PCR, sequencing, cloning, or microarray work without diluting precious samples. Molecular biology, genomics, and research labs quantify DNA and RNA extractions, while protein labs run colorimetric assays. Pathology institutes assess nucleic acid quality before diagnostic testing, and food industry labs check DNA extracts from raw materials and finished products. See the Micro Volume Spectrophotometers and Micro Volume Spectrophotometer pages for full specifications.
