Lyophilizer
MAKE DINESH SCIENTIFIC MODEL DS-LPZR-50
PRODUCT DESCRIPTION:
Lyophilizer Freeze Dryer is manufactured in compliance with latest technology using best quality materials and components. Equipped with self temperature adjustable, controllable and detectable functions, our dryer is used for pre- freeze drying process. Bottom of the machine is attached with caster wheels for easy mobility. We offer this Freeze Dryerat market leading prices. The unit has hermetically sealed compressor to maintain temp. Control by electronic digital controller cum indicator with electronic vacuum indicator.
PRINCIPAL OF LYOPHILIZER:
The basic principle in lyophilization is sublimation, in which the conversion from a solid directly into a gas occur. Just like evaporation, sublimation occurs when a molecule gains enough energy to break free from the molecules around it.
PURPOSE OF LYOPHILIZER:
A lyophilizer executes a water removal process typically used to preserve perishable materials, to extend shelf life or make the material more convenient for transport. Lyophilizers work by freezing the material, then reducing the pressure and adding heat to allow the frozen water in the material to sublimate.
USES OF LYOPHILIZER:
lyophilized biopharmaceuticals include blockbuster drugs such as etanercept (Enbrel by Amgen), infliximab (Remicade by Janssen Biotech), rituximab, and trastuzumab (Herceptin by Genentech). Freeze-drying is also used in manufacturing of raw materials for pharmaceutical products.
