酶免仪负压泵的替代

Substitution of Elisa Miriam Reader Vacuum Pump

目的:用国产负压泵替代进口酶免仪用微型负压泵,进一步延长该机的使用寿命。方法:采用电动吸引器(YB.Dx23D)作为负压源与进口酶免仪的排污真空桶相接,将其电路进行改造,使负载与主机负载相匹配,实现了主机与负压泵同步工作。结果:改造后的YB.Dx23D电动吸引器与同类相比,噪声低、负压高、流量大、体积小、可移动。结论:改造后的YB.Dx23D电动吸引器在全自动酶免仪的冲洗板、排废液中运用效果良好,同时适用于其他需要抽吸负压(真空)的仪器设备。

Objective To replace the imported vacuum pump with a Chinese-made instrument using a micro-ELISA negative pressure pump, to further extend the life of the machine. Mothods Electric aspirator（YB.Dx23D） was used as source of negative pressure to connect with barrels of waste and the vacuum-phase of imported enzyme immuuoassay instrument. The circuit was transformed, and the host matched the load, so the host and negative pressure pumps worked simultaneously. Results Compared with other aspirators, the modified electric aspirator YB.Dx23D has low-noise ratio, high negative pressure, vast flow, small volume, and mobile function. Conclusion The modified aspirator YB.Dx23D electric instrument is well used in washing ELISA plates and the effective use of waste water. Meanwhile, it can be applied to other necessary suction negative pressure （vacuum） equipment.
