Preferably, the gun head body 1 is a T-shaped tube body with an upper part capable of being matched with a pipetting gun, and the soft coating part 2 is a conical gun head with a bayonet arranged inside and capable of being tightly clamped with the T-shaped tube body.
Preferably, the gun head body 1 is a structure of a conventional pipette gun head after being beveled through a liquid outlet, and the soft coating piece 2 is an elliptical ring which wraps the notch and is matched with the notch in shape.
Preferably, the gun head body 1 and the soft coating member 2 are made of materials resistant to high temperature and high pressure.
Furthermore, the gun head body 1 is made of polypropylene plastic, and the soft coating member 2 is made of silica gel or rubber.
The utility model has the beneficial effects that:
1. the coating device has the functions of pipetting and coating, does not need to match a pipettor with a coating rod for coating, does not need to bend in the coating process, and is time-saving and labor-saving; 2. the pipette has the pipetting function of a common gun head, can be arranged in a gun head box and is matched with a standard pipetting gun for use; 3. all are disposable products, and the production cost is low; 4. can be sterilized under high pressure, and does not need flame burning when in use, thereby eliminating potential safety hazard.
The integrated liquid-transferring coating gun head has the advantages that the structure is simple, the liquid-transferring and coating functions are integrated, the defects of a traditional coating rod can be overcome, great convenience is brought to coating operation experiments, the working efficiency is effectively improved, and the problems of low traditional coating efficiency, easiness in pollution and the like can be solved.
