Labmate Micro Spectrophotometer LMMS-A901
Labmate Micro Spectrophotometer LMMS-A901 is a high-precision instrument designed for rapid and accurate analysis of DNA, RNA, and proteins using ultra-low sample volumes. Operating across a broad wavelength range of 180–910 nm, it supports micro-volume samples from 0.5–2 μL (2 μL recommended) without requiring dilution. Equipped with a 2048-element linear CMOS array detector and a long-life Xenon flash lamp (over 10⁹ flashes), it delivers precise absorbance readings with high sensitivity for low-concentration samples. The device completes measurements in under 6 seconds, making it ideal for high-throughput laboratory workflows.
