Vacuum pumps are a versatile piece of laboratory equipment for suctioning via negative pressure. They are routinely used in biological sciences for filtration, distillation and concentration of volatile solvents, solid phase extraction, freeze drying, and more. Even though vacuum pumps share a common function, there are many considerations to take into account when choosing a new pump. The ...
Introduction Freeze-drying is used to produce the majority of today's dried pharmaceuticals, i.e. those compounds that require reconstitution with water prior to use. Freeze-drying or lyophilization refers to the only manner in which water can be removed from organic substances without damage to the cell structure and subsequent loss of volatile components. The process requires freezing the ...
In Hooke College of Applied Sciences’ 2 1/2 day freeze drying short course, you’ll work in small groups to examine formulations containing pharmaceutical excipients. Each group builds data sets for their formulation using DSC, freeze dry microscopy and micro freeze dryers. You’ll have ample time to discuss ...
Rotary Vane pumps are able to achieve much lower vacuums than diaphragm pumps, so are often used in more demanding applications such as with glove boxes or freeze dryers. Diaphragm Pumps Diaphragm pumps are usually oil free and low maintenance. ...
The Transfusion-Associated Graft-Versus-Host Disease (TA-GVHD) is a serious potential complication of blood transfusions that is essentially prevented by blood product irradiation. In this study, scattering profiles from lyophilised and irradiated samples of plasma (PL) and formed elements (MC) were compared with non-irradiated ones. Fresh blood specimens were obtained from volunteers by vein ...
This article presents results of an experimental study of (AFD); atmospheric freeze-drying which uses a vortex tube to produce low temperature air, as an alternative to vacuum freeze-drying (VFD). ...
