As stated earlier, at a given temperature the optimal gas flow may be defined as the highest velocity at which the gas jet can impinge on the solvent surface without causing excessive turbulence. This being the case there are in essence two potential operational modes (1) a uniform operational mode in which all of the sample vials are identical and all of the samples are intended to be processed in the same manner and (2) an incongruous operational mode in which individual samples are of varying size or composition and therefore require different process parameters.
In previous discussions, it was noted that the two key factors affecting the evaporation rate of a given solvent are temperature and gas flow. Further, the evaporation rate of the subject solvent has been shown to increase with a corresponding increase in either of these variables. Increasing the bath temperature increases the solvent's vapor pressure and its volatility so that the solvent vapor collects in the sample holder to the saturation point, while increasing the flow of gas into the sample holder physically removes the solvent vapor.
Berlin, MA, September 5, 2014 – In an effort to highlight one of the company's fastest growing instrument types, Organomation.com's solvent evaporator section has been dramatically enhanced. A new organization scheme, high quality photographs and detailed content will be immensely helpful to established customers and prospective buyers alike.
Berlin, MA, August 1, 2014 – Last month, Organomation announced a new program which allows customers to trade in their used evaporator or extractor for credit which will be applied towards a new instrument purchase. For over fifty years, Organomation has built a reputation of producing long lasting laboratory instruments and the company sought to reward its faithful customers with this special promotion.
Berlin, MA, July 11, 2014 – Earlier this year, Organomation proudly lengthened the standard warranty for some of its most popular nitrogen evaporators from one to two years. Since 1959, laboratory professionals have chosen the company's evaporators and extractors due to their durability, ease of use and value. Organomation firmly stands behind its instrument's quality by extending the standard warranty length for several evaporator models.
Berlin, MA, June 10, 2014 – Organomation is happy to announce that the sample holders used in the company's popular N-EVAP product line have been upgraded. The company stands behind the quality of their products and looks to consistently strengthen the brand's reputation for producing long lasting laboratory evaporators and extractors.
Organomation announces a sale on a wide variety of newly refurbished laboratory evaporators and extractors in the company's official online store. The evaporator manufacturer fully stands behind the quality of their products by offering a one year warranty on their factory refurbished instruments. Laboratories can purchase these instruments at up to 50% off of the list price of a new instrument.
In a nitrogen evaporation instrument, temperature and gas flow rate are the two major operational parameters that determine the rate at which the solvent is removed from a system. However, it is too large of an assumption to presume that both a higher temperature and gas flow rate will produce the most effective removal of solvent. Adjusting the bath temperature can have varying effects on the analyte, and it is important to remember that a higher temperature is not always optimal.
It is often said that the best place to catch a disease is in a hospital; likewise, the most common place for sample contamination to occur is in the analytical laboratory. Sample contamination may be defined as the inadvertent addition of target or detectable analytes to samples during the sample collection, transportation, preparation, or analysis processes.
Berlin, MA, December 2, 2013 – Organomation announces the newly redesigned MICROVAP product line. These evaporation systems are designed for controlled concentration of small samples. All four models in the product line are light, compact and digitally controlled for ease of use.
