Incubation and magnetic separation device applied to chemiluminescence determination

Abstract

The invention discloses an incubation and magnetic separation device applied to chemiluminescence determination and belongs to the field of chemical luminescence determination. The incubation and magnetic separation device applied to the chemiluminescence determination comprises an incubation device and a magnetic separation device, wherein the magnetic separation device is arranged at one side of the incubation device, so that a magnet on a magnet frame corresponds to a bottom side face of a reaction cup on a reaction cup hole. The incubation magnetic separation device integrates an incubation function and a magnetic separation function; a temperature range and magnetic selection time are accurate and adjustable; the device is stable in properties and simple to operate. The incubation device adopts contact type direct heating and has a good incubation effect; the magnetic separation device has the advantages of good buffering effect and reduction of loss of magnetic beads and the like.

Description

technical field [0001] The invention relates to the field of chemiluminescence measurement, in particular to an incubation magnetic separation device applied to chemiluminescence measurement. Background technique [0002] Most of the incubation devices in the prior art are rotary disk-type incubations, and heating methods such as air baths are mostly used. The heating speed is relatively slow, and is greatly affected by external factors, and the temperature fluctuation is large, which will seriously affect the incubation reaction, and then affect the temperature. measurement results. [0003] At the same time, there are many wires connected to the heating device in the incubating device, and the wires are prone to entanglement during the movement of the turntable, causing machine failure and affecting work efficiency. [0004] The magnetic separation device in the prior art generally fixes the magnet completely in the magnet fixing block, so that when the magnet contacts th...

[0002] Most of the incubation devices in the prior art are rotary-disk incubations, and heating methods such as air baths are mostly used. The heating speed is relatively slow, and is greatly affected by external factors, and the temperature fluctuation is large, which will seriously affect the incubation reaction, and then affect the temperature. measurement result

[0003] At the same time, there are many wires connected to the heating device in the incubator, and the wires are prone to entanglement during the movement of the turntable, causing machine failure and affecting work efficiency

[0004] The magnetic separation device in the prior art generally fixes the magnet completely in the magnet fixing block, so that when the magnet contacts the cuvette, there is no elastic setting but a head-to-head collision, which will cause a great impact on the cuvette wall , in severe cases, it may even cause the cuvette to rupture

[0005] In addition, magnetic separation is generally performed at the bottom of the cuvette, and the bottom of the cuvette is at the same height. After the magnetic separation is completed, the liquid aspiration needle is inserted into the bottom of the cuvette to draw liquid during cleaning, and the magnetic beads are easily removed at the same time, resulting in magnetic severe bead loss
