Group: The instrument consists of a plate washing machine, a washing liquid bottle, a distilled water bottle, a waste liquid bottle, an 8 needle flushing spray head and a 12-needle washing spray head. Want to ask: 1) cleaning row number: it can be set arbitrarily within the range of row 1-12; 2) soaking time: it can be set arbitrarily within the range of 0s-3600s; 3) cycle times: set arbitrarily once -- 20 times; 4) the device can set and save up to 100 washboard procedures; 5) washing method: 96 holes (or 48 holes) of enzyme label plate can be cleaned according to 8 holes in each row or 12 holes in each row; 6) infusion uniformity: uniformity of the amount of each hole washing liquid injected in the enzyme label plate: less than or equal to 5%; 7) residual amount: the average residual amount of each hole washing liquid in the enzyme label plate after washing is less than 2. 8) pipeline flushing function: it has the function of flushing the instrument's own pipeline, and can be set arbitrarily within the range of 0s-600s; 9) liquid exchange time can be adjusted: it can be set arbitrarily within the range of 0s-600s; 10) it has the function of vibration plate: it can be set arbitrarily within the range of 0s to 60s; 11) it has the function of preventing overflow: when the infusion is excessive, the excess lotion will be sucked away automatically and will not flow into the instrument; 12) two-point liquid suction function: the instrument has two-point liquid suction function, and the two-point space can be adjusted; 13) rinsing at the bottom of the hole: the instrument has the function of rinsing at the bottom of the hole; 14) range of injection per hole: set within 10 ul-3000ul range. Scope of application: This instrument needs to be used in conjunction with the lotion in the enzyme free reagent registered by the state drug administration. It is mainly used for: 1) washing of enzyme label plate and culture plate during enzyme label detection in hospitals and relevant departments; 2) cleaning in microanalysis of chemical, biochemical and other aspects.
