Lyophilization, also known as freeze drying, is a process used for preserving biological material by removing the water from the sample, which involves first freezing the sample and then drying it, under a vacuum, at very low temperatures.
A customer approached Digivac to assist with vacuum control in an electron microscope. A vacuum within the microscope deeper than 20 Pascals (approx. 150 millitorr) causes visible degradation in the final image. The customer needed the ability to measure inside the chamber and precisely control the vacuum between 20 and 30 pascals while the electron microscope captures the image.
Some materials are super sensitive to temperature making it more difficult to vacuum dry . It is crucial to make sure that the temperature remains constant as it can end in a loss of materials if an error were to happen. Not being able to completely control your vacuum can result in making you restart the process back to square one.
Rotary evaporators are advanced scientific instruments that are commonly used in chemical laboratories, processing laboratories and in research to facilitate fractionation. This separation process allows the solvents to be removed gently through evaporation and the precise control of the temperature.
Solvent recovery is the process of extracting target products from waste or by-product solvents generated during the manufacturing process. These chemicals can then be repurposed, reducing the need to produce or purchase new solvents, while eliminating a large amount of waste and removing potentially hazardous substances from the primary processed material
Capacitance manometers are modern devices that are much more accurate than their predecessors. Use this article to learn about their many benefits.
Many people come to find out that they have problems when it comes to vacuuming powder. Especially drying fine powder that tends to get puffed up and pulled into the vacuum pump flooding it. With the pumps flooded this leads to an unfortunate problem, one you end up losing the powders you’re trying dry and two it isn’t the best for your pump either.
