In laboratories, clinics, pharmaceutical plants, and research institutions, sterility is not just a standard—it’s a foundation. Whether you're working
In modern analytical laboratories,sample preparation is often the most time-consuming step—and one that significantly affects accuracy and throughput. For labs handling volatile solvents and small-volume samples,a nitrogen blowdown evaporator (commonly known as a nitrogen evaporator) is a simple yet powerful tool that can dramatically improve evaporation speed while preserving analyte integrity.
At our factory,we specialize in the development and export of precision nitrogen evaporators that help laboratories save time,reduce sample loss,and streamline workflows across pharmaceutical,environmental,food safety,and chemical industries.
The nitrogen evaporator uses a stream of dry,inert nitrogen gas to gently blow over the surface of a liquid sample. This promotes rapid evaporation of volatile solvents at low temperatures—without the risk of oxidation or thermal degradation.
Ideal for:
l Sample concentration before LC,GC,or MS analysis
l Solvent removal in pesticide residue or drug testing
l Preparation of serum,plasma,plant extracts,or environmental samples
Because nitrogen is inert,it doesn’t react with sensitive compounds,making it safer and more precise than traditional open heating or rotary evaporation in some use cases.
Explore our Basic 12-Position Nitrogen Evaporator – perfect for daily small-batch sample prep in analytical labs.
Our nitrogen evaporators are built with the needs of modern laboratories in mind. Each unit features:
l Adjustable gas flow control per needle
l Temperature-controlled water bath or dry heating block
l Sample vial holders with modular configuration (12,24,36 positions,etc.)
l Easy-to-clean stainless steel or anodized aluminum construction
Some models support dual temperature zones,digital timers,and automatic lift mechanisms,helping lab technicians standardize procedures and improve reproducibility.

Our nitrogen evaporators are widely used in laboratories performing:
l Pharmaceutical quality control – concentrate active ingredients prior to HPLC analysis
l Environmental monitoring – evaporate organic solvents from water or soil extracts
l Food and beverage safety – remove solvents from flavor compounds or contaminants
l Clinical diagnostics – prepare biological samples for toxicology or hormone testing
With precision control over evaporation conditions,these systems help users minimize analyte loss,especially when working with trace-level compounds or thermally labile substances.

All our nitrogen evaporators are manufactured in an ISO9001-certified facility,and meet CE and RoHS standards for export to Europe and North America. Every unit undergoes:
l Gas flow accuracy testing
l Temperature uniformity mapping
l Safety valve and overheat protection checks
l 24-hour continuous operation validation
We provide support for various power configurations (110V/220V,50Hz/60Hz) and ship globally with protective packaging and clear installation guides. Remote video assistance is available for first-time users.
