(1) the use of diaphragm before and after the action of the diaphragm and the pump head changes between the ball valve up and down movement to form a vacuum adsorption and push phenomenon to achieve the purpose of liquid delivery. â‘ When the diaphragm is pulled backwards, the outlet ball valve falls tightly close to the ball seat â‘ , the inlet ball valve rises upward due to the vacuum generated between the pump diaphragm and the diaphragm after the diaphragm â‘¡, and the liquid is sucked up. â‘¡When the diaphragm is pushed forward, the inlet ball valve and the ball seat are airtight â‘£, so that the liquid will not pass, and the outlet is pushed forward by the diaphragm to open the ball valve â‘¢ and the liquid is spit out. (2) From the above action principle Simply know the diaphragm, pump head, ball valve ball seat caused by any one factor leakage is unable to achieve the purpose of delivery, or abnormal flow, usually resulting from the failure of the four main students: â‘ ball seat and ball valve can not be airtight â‘¡ entrance, exit foreign body obstruction â‘¢ membrane damage If the liquid delivery abnormalities, handling in this regard, should be resolved, and the factors that caused the above conditions, numerous, end of the view of the piping, fittings and operating conditions can be determination
Microcentrifuge Tube
High-performance microcentrifuge tubes, optimized design, and high-performance quality help protect your samples. Microcentrifuge tubes are made of polypropylene (PP) and are highly mechanically stable, ensuring your samples are stored, run and centrifuged worry-free.
Microcentrifuge tubes have a maximum centrifugation tolerance of 25,000 x g and are autoclavable (20 minutes, 121°C). The centrifuge tube adopts a snap-on tube cover design, which can be operated with one hand and has good sealing performance, which can effectively prevent liquid leakage; the tube wall is smooth, and the tube body is designed with a frosted area for convenient marking.
