Magnetic bead lyophilized sphere manufacturing apparatus and method

Abstract

The application discloses a kind of magnetic bead lyophilization ball production equipment and method, can automatically produce magnetic bead lyophilization ball, production efficiency is high, and forming qualified rate is high.The production equipment includes mixing mechanism, dispensing mechanism, pipetting mechanism and electric control device;Mixing mechanism includes sample container;Sample container is used to contain and mix the sample liquid containing magnetic beads;Dispensing mechanism includes several liquid nitrogen cups arranged along the X-axis direction, liquid nitrogen cup is used to contain liquid nitrogen to cool the sample liquid injected therein;At least one liquid guide rod that can vibrate is provided in each liquid nitrogen cup, and the liquid guide rod is arranged along the Z-axis direction;Pipetting mechanism includes sample suction head, and sample suction head is movably matched above sample container and liquid nitrogen cup, and sample liquid is sucked from sample container according to the preset quantity, and sample liquid is injected into liquid nitrogen cup, and when injecting, sample suction head is aligned above liquid guide rod to make sample liquid flow down along liquid guide rod;Electric control device controls the action of mixing mechanism, dispensing mechanism and pipetting mechanism.
