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.
There are many different methods used in today’s laboratories to assist in the concentration and/or drying of samples. Many of these methods use a combination of techniques, such as temperature increase and vapor pressure reduction, to expedite the solvent evaporation process. For example, Organomation’s N-EVAP nitrogen evaporators combine nitrogen blow down with a heated bath to accelerate concentration.
Berlin, MA, October 18, 2013 – Organomation unveils a plan to publish several laboratory evaporator themed pieces to the company's blog this Fall. This series of short articles will include many useful tips for users of the popular N-EVAP product line and Organomation's other nitrogen evaporators.
Sales and Marketing Manager David Oliva stated that “we are thrilled to publish and distribute these high quality research pieces for our website visitors. We hope to provide informative data about our laboratory evaporators in an easy to understand format.”
Although buying a used laboratory evaporator gives you the possibility of saving some money upfront, often times the savings do not offset the cost of fixing the used instrument later on. In most cases, buying a brand new laboratory evaporator is actually a more cost efficient option. Preparing a sample that is free of contaminants is the goal of any analytical chemistry organization. The last thing you want is to do is worry that the second hand sample concentrator you bought may be jeopardizing your operation.
6 Tips for Purchasing a Laboratory Evaporation System: Any time you need to purchase high end laboratory equipment, the sales process can be very stressful. Sales representatives are looking to fill their quotas in order to receive their commissions and to reach production goals. In order to make sure that you get the best deal on the right sample concentrator, make sure you ask these six questions in order to potentially save thousands of dollars while also making sure you are ordering the best possible instruments for your specific lab and testing methodologies.
