Laboratory Stirrer: Easily attachable stirring assembly to a glass flask to distill heat sensitive material under vacuum and stirring. This unique laboratory stirrer is designed taking into consideration the difficulties a scientist has to face while distillation under vacuum in a glass assembly. This easily attachable stirring assembly helps to disperse the material, avoiding localized heating, which in turn avoids cracking, polymerization of the material and burnt note of the distillate. Laboratory stirrer also makes the distillation efficient by increasing the yield and reducing residual content. In short it is a perfect solution for distillation of heat sensitive material under vacuum while stirring.
