The Nitrogen Evaporation category presents advanced systems for concentrating liquid samples by evaporating the solvent using a controlled stream of nitrogen gas. This method is particularly effective for preparing samples prior to chromatographic analysis (GC, HPLC), for concentrating fractions after extraction, or when rapid solvent evaporation is needed at room temperature or with gentle heating, without requiring a vacuum system.
Nitrogen evaporation systems work by directing a stream of inert nitrogen gas through needles or nozzles aimed directly at the liquid surface in each sample. The nitrogen flow disrupts the solvent vapor-saturated boundary layer above the liquid, carrying the vapors away. This lowers the partial pressure of the solvent above the sample and significantly accelerates the evaporation rate.
Often, these systems also incorporate controlled heating of the samples (via a heating block or water bath) to provide the necessary energy for evaporation and further speed up the process. Using nitrogen, an inert gas, prevents oxidation of sensitive samples during evaporation and heating. The gas flow rate and heating temperature can be controlled to tailor the process to the solvent type and sample sensitivity.
The nitrogen blowdown method is common in a wide range of analytical and sample preparation applications:
Labotal is proud to offer the advanced RapidVap® N2 Evaporation System from the American company Labconco, a benchmark for quality and reliability in laboratory equipment. RapidVap N2 systems allow for fast and efficient evaporation of up to 48 small samples simultaneously (depending on the model and sample block), utilizing controlled heating and distributed nitrogen flow to each sample.
These systems feature precise microprocessor control of temperature and evaporation time, allowing custom programs to be stored. The compact design and high efficiency make the RapidVap N2 an ideal solution for streamlining sample preparation in high-throughput laboratories.
