NITROGEN EVAPORATION BATH

Nitrogen evaporators (water bath type) are typically used “to concentrate samples before analysis or to concentrate samples before a solvent exchange.When a scientist needs to concentrate a sample that’s in a volatile liquid—like acetone, acetonitrile, or methanol—a nitrogen evaporator can do the job. As a result, scientists use this technology in sample preparation in environmental, polymer science, quality control, and toxicology labs etc.Our nitrogen evaporators utilize adjustable nitrogen blow down technology allowing full control of nitrogen flow to samples, with no wasted nitrogen gas. We combined this technology with uniform efficient heat applied through water baths. This simultaneously maximizes solvent evaporation in the samples being concentrated and saves the lab money.

The 24 position WEIBER nitrogen evaporator is our most adaptable version but we can customize it to 6/12/34/50 positions as per the requirement.

• Microprocessor based control system.
• Can accommodate samples with an outside diameter of 10-30 mm.
• Provides controlled concentration of sample vials through the application of nitrogen gas within a heated water bath.
• The dual band spring hoist assembly provides a simple and effective means of removing samples from the heated water bath.
• Circular rotating design permits each sample to be accessible from the front of the instrument for easy insertion and retrieval.
• The chrome plated needle valves are individually milled from solid brass, enabling precise, uniform adjustments for your nitrogen blow down.
• Efficient and safe sample reduction with minimal nitrogen waste.
• Long lasting and user friendly technology
• Gas flow can be controlled at each sample position via needle valves
• Nitrogen filter
• High pressure phthalate free tubing for safety, Teflon tubing for no contamination
• Needles, 4 inch x 19 gauge with polypropylene hub and stainless steel shaft
• 220v wiring harness (optional)
• Z-Purge/intrinsically safe purge case (optional)
• Acid resistant coating on instrument and needles (optional)
• Side control box with built-in digital controller, timer, and pressure regulator (optional)
