3. Detailed Product Description

Product Overview

The Labmart DBNE24 Dry Bath Nitrogen Evaporator is a laboratory sample concentrator that uses nitrogen gas blown onto heated sample surfaces to assist controlled solvent evaporation.

The DBNE24 is designed for higher-throughput sample processing, providing 24 sample positions with 16.5 mm diameter openings. Its 600 W heating system works with an aluminium block bath designed for even heat conductivity and rapid temperature control. DBNE12

The instrument uses a microcomputer-controlled processing unit with PID control, providing a temperature range of R.T. +5°C to 150°C, 0.1°C display resolution and temperature-control accuracy of ≤±0.5°C.

Nitrogen is delivered through the gas distribution assembly and needle system. The catalogue specifies a maximum gas pressure of 0.12 MPa for the DBNE24. DBNE12

5. Technical Specifications

The above model-specific specifications are provided in the DBNE12/DBNE24 technical table in the supplied catalogue. DBNE12

6. How the DBNE24 Works

The DBNE24 uses nitrogen-assisted dry-bath evaporation.

Operating Principle

Load Samples → Set Temperature → Position Nitrogen Needles → Start Nitrogen Flow → Heat Samples → Controlled Solvent Evaporation → Sample Concentration

Nitrogen is blown onto the surface of heated samples in a fast, consecutive and controllable manner. The aluminium block provides heating and temperature control while nitrogen assists evaporation.

The catalogue describes nitrogen blowing as achieving oxygen-free concentration, making the system suitable for controlled sample concentration workflows. DBNE12
