Abstract
A microparticle filling method of the present disclosure is a method of filling at least one or more containers with microparticles, including: sucking a suspension of the microparticles into a nozzle; concentrating the microparticles in the suspension to form a high-concentration suspension having a predetermined microparticle concentration at a tip of the nozzle; bringing the high-concentration suspension in contact with an inner wall of the container; and separating the nozzle from the container after the contact to fill the container with the high-concentration suspension.
Claims12
A microparticle filling method of filling at least one or more containers with microparticles, the microparticle filling comprising:
- sucking a suspension of the microparticles into a nozzle;
- concentrating the microparticles in the suspension to form a high-concentration suspension having a predetermined microparticle concentration at a tip of the nozzle;
- bringing the high-concentration suspension in contact with an inner wall of the container;
- separating, after the contact, the nozzle from the container to fill the container with the high-concentration suspension;
- and
- sensing the contact of the high-concentration suspension with the inner wall of the container based on stress applied to the nozzle.
A microparticle filling method of filling at least one or more containers with microparticles, the microparticle filling comprising:
- sucking a suspension of the microparticles into a nozzle;
- concentrating the microparticles in the suspension to form a high-concentration suspension having a predetermined microparticle concentration at a tip of the nozzle;
- bringing the high-concentration suspension in contact with an inner wall of the container;
- and
- separating, after the contact, the nozzle from the container to fill the container with the high-concentration suspension,
- wherein the microparticles are magnetic microparticles, and the high-concentration suspension is formed by collecting the microparticles in the nozzle at the tip of the nozzle using a magnet.
