Nano Spectrophotometer BJN-4501
Micro-volume Spectrophotometer
Key Features
- Microscale sample testing; only 0.5-2 μL is required to complete the test, with a minimum sample volume of 0.5 μL. Supports both ultramicro and cuvette measurement.
- Wide detection range, up to 500 times that of a traditional spectrophotometer.
- Most samples can be tested directly without dilution.
- Direct testing with no warm-up required; suitable for container testing and routine testing.
- Full wavelength coverage of 190-1100 nm with 1 nm accuracy; automatic wavelength scanning from 190-900 nm.
- Compact and portable design, suitable for on-site testing.
- 2-in-1 functionality with support for OD600 detection, suitable for measuring the growth density of cells, bacterial cultures, yeast, and other samples.
- Built-in thermal printer with printing capability; can store approximately 100,000 sets of detection data and supports data export through a USB interface.
