Flask Pear Shape

Flask Pear Shape Introduction

Standard grinding flask with good adhesion. The pear shape increases the surface area of the liquid and accelerates solvent evaporation. And if a large amount of oil is prepared, the final oil will flow to the bottom of the pear-shaped bottle, which is beneficial to the removal and reduce the loss. For spin concentration, synthesis reactions can also be carried out.
