By incorporating with various feeding equipment, the retainer can perform coated and scattered dispension, which solves the problems from frequent syringe replacement and glue leakage.The design of special diaphragm can achieve accurate dispensing amount via pneumatic pressure and adjustment at top, which is applicable for operation procedure with colloid of medium-low concentration and low dispensing amount.For internal structure, Teflon-like materials are adopted for providing corrosion resistance and prevent the metal-reacted colloid from solidifying in retainer, which is particularly suitable for short surface drying time (e.g. super glue).
