HM-CWF1 Ultra-Micro Spectrophotometer

Product Introduction

The HM-CWF1 Ultra-Micro Spectrophotometer is a compact, all-in-one biological analysis instrument designed for rapid quantification of nucleic acids and proteins in laboratory environments. Built on UV-Vis spectrophotometry and Beer-Lambert's Law (A = εcl), it provides accurate absorbance measurements at three fixed wavelengths — 230 nm, 260 nm, and 280 nm — along with a dedicated OD600 module for bacterial culture monitoring.

Unlike conventional cuvette-based photometers, the HM-CWF1 employs liquid column surface tension technology, allowing direct measurement of sample volumes as low as 0.5–2 µL without dilution, cuvettes, or capillary tubes. This consumable-free design minimizes sample loss and significantly reduces per-test costs, making it particularly suitable for labs handling precious or volume-limited biological samples.

The instrument integrates a UV-enhanced CMOS linear array sensor and a high-stability pulsed xenon lamp (PP value <0.5%), ensuring consistent photometric accuracy across extended use. A three-light-path switching mechanism (0.04 mm, 0.2 mm, 1.0 mm) extends the measurable concentration range to over 150 times that of standard UV-Vis spectrophotometers. The built-in Android 10 operating system with a 7-inch HD touchscreen, integrated thermal printer, and Wi-Fi/Ethernet connectivity delivers a fully self-contained workflow from sample loading to result archiving.

• Routine QC in biopharmaceutical manufacturing processes

Functional Performance / Features

1. Three fixed detection wavelengths (230/260/280 nm): Optimized for standard nucleic acid and protein absorbance measurements without full-wavelength scanning overhead.

2. OD600 bacterial culture module: Measures bacterial and other culture media concentration directly; OD600 absorbance range 0–4 Abs, stability ≤1%, repeatability ≤1%.

3. No-dilution, no-consumable design: Liquid column surface tension technology supports 0.5–2 µL direct measurement, eliminating cuvettes and capillary tubes.

4. Three-light-path automatic switching: Motor-controlled selection between 0.04 mm, 0.2 mm (high-concentration), and 1.0 mm (standard concentration) optical paths for a detection range equivalent to 0.04–300 A (10 mm path).

5. High-stability xenon lamp light source: Pulsed xenon lamp with PP value <0.5% ensures minimal baseline drift for reproducible results.

6. UV-enhanced CMOS linear array detector: Delivers absorbance precision of 0.003 Abs and accuracy of ±2% (0.76 Abs @ 260 nm).

7. Fast detection — results in under 6 seconds: Suitable for high-throughput screening and routine quality control in busy laboratory environments.

8. 7-inch HD Android 10 touchscreen: Intuitive UI with dedicated modules for Nucleic Acid Test, Protein Test, OD600, and more, all accessible from the home screen.

9. Built-in thermal printer: Generates printed reports on-site without external peripherals.

10. Wi-Fi and Ethernet connectivity: Supports multi-mode data upload, batch export via USB, and remote software upgrades over the cloud.

11. 7000 mAh lithium battery (21.6 V): Provides up to 8 hours of continuous operation, enabling flexible field and bench-top use.

12. Large data storage: Stores 10,000–100,000 entries, searchable and exportable via USB.
