Good quality quartz glass material , high accurate , many sizes
The method of use ] : when using the flask wash, drying, since the bottleneck department into distillation material, most should not be more than two-thirds of the sphere volume, at least should not less than one-third. Then will have good hole in the rubber plug or cork, according to needs to be inserted in the thermometer or separatory funnel and so on equipment, thermometer water arguably part should be inserted branch the following 5 ~ 10 mm impose guarantee temperature measurement is correct, then install in the bottle mouth, will flask fixed on the top of the shelf. Branch pipe connected condenser pipe, condenser pipe bottom and bent over connection, condenser pipe also fixed well, and then open condensate water, fire or water bath, oil bath for to boiling, causes the liquid evaporation, distillation substances by condensing pipe distillate, through the bent over drip into the accept in the bottle. If distillation for two or three different material, and, according to the different temperature distillation exchange are bottle, can see the distillation material purification and separation. In order to avoid boiling liquid detonation, in advance in the bottle is put inside a few single glass bead or zeolite.
