Standard grinding mouth: frosted and fine, sealed without air leakage

Firm welding: 1100°C production, 600°C annealing

High borosilicate glass: 200mm can withstand 600°C high temperature and 200°C temperature difference

Pagoda head: multiple hoops with small mouths and tight skin tube links

Used as laboratory equipment to facilitate condensation, acting as condensation or reflux

It consists of two glass tubes, inside and outside, with the smaller glass tube running through the larger glass

The glass pipe, the upper and lower sides of the outer tube have pagoda heads, which are used to make water

mouths and water intakes.

Straight condenser tube: The inner tube is a straight glass tube, which is suitable for the distillation and fractionation operation of substances with a boiling point below 140 °C, and is mainly used in inclined distillation devices
