Overview

What this instrument measures, and how it fits the range.

The UM Series Nano Spectrophotometer covers six models, UM-100 to UM-330, with wavelength accuracy from ±1 nm to ±2 nm and a 1 mm optical path across the range. The two sub-families are built for different workflows, so their features are listed separately.

UM-100 and UM-110

Minimal sample volume required, with full UV-Vis wavelength scanning.
No preheating required, so the instrument is ready to test at any time.
Fast detection speed, with the concentration value displayed directly.
Samples do not need to be diluted, and the data statistics software is easy to master.

UM-200, UM-220, UM-300 and UM-330

A built-in optical fiber prevents breakage from external impact, which would otherwise lead to inaccurate results.
Multiple data output ports allow test data to be exported freely.
The software supports remote operation.
Standard curves support several fitting functions: linear, interpolation, second-order polynomial and third-order polynomial.
Optional modules include full-wavelength scanning, standard curve quantitative analysis, kinetics and photometric measurement.

Key points

Touchscreen pad interface with multi-interface design and automatic Bluetooth connection. Real-time data monitoring and automatic performance optimization. Software-aided fault inspection and localization.
Multi-color status indicators: blue for ongoing self-test, yellow for standby or preheating, green for normal operation and red for faults such as an abnormal light source.
One-click switching between microvolume mode and cuvette mode without additional disassembly, covering analysis from microvolume to regular samples on one instrument.
Pre-set program calling supports one-click startup and preloading of frequently used programs, shortening test startup time.
Long-life xenon lamp paired with a high-pixel linear CMOS sensor, covering 200-900 nm with absorbance from 0 to 600 Abs. A single measurement completes within 5 seconds.
Quantum-level sensitive materials in the light-detecting components capture photons and resolve subtle changes in light passing through the sample.
Real-time SMS and email push when the instrument fails or a result is abnormal, with errors, warnings and informational messages recorded as they occur.
Operating software carries 21 CFR functions, with system administrator, administrator and operator roles separated by distinct permissions.
Cloud interconnection: the IoT platform supports real-time monitoring and remote control, with data upload, storage, viewing and sharing across WeChat Mini Program, APP and desktop.
