A droplet vitrification apparatus based on a spiral tube

Abstract

The utility model discloses a kind of liquid drop vitrification devices based on spiral pipeline, including liquid nitrogen tank, built-in frame, collection mechanism, cooling pipe and feed pipe and the like components.The device is designed through spiral pipeline, so that liquid drop is effectively extended in low-temperature environment Flowing time, avoid the temperature difference problem caused by liquid drop stationary in traditional cooling method, ensure that the uniform reduction of liquid drop surface and internal temperature, prevent the formation of local ice crystal.The inclination of feed pipe is set to reduce the impact force when liquid drop enters spiral pipe, maintain the stability of liquid drop form.Collection mechanism is connected with cooling device through discharge pipe, realizes the lossless recovery of liquid drop, reduces pollution risk and improves experimental efficiency.The clamping jaw design of built-in frame enhances the stability of device, avoids the loosening of component caused by temperature change, and facilitates the maintenance and operation of device.
