Chromo4 多色實時熒光定量PCR儀
產品介紹：
Chromo4 是一款四波長實時PCR 儀，由DNA Engine 和光學模塊組合而成 （即 DNA Engine 可升級為Chromo4）。如同 DNA Engine 系列一樣，其配備的Alpha加熱
模塊可以無需工具快速更換。 同樣，Chromo4 繼承了DNA Engine 優良的溫度控制性能和眾多的高級設置（如梯度 PCR 功能等），其出色的重復性保證了結果 的可靠。
其他性能如下：
可在一臺 Dyad Disciple 上安裝兩臺 Chromo4 光學模塊
一臺電腦可以最多同時連4 臺 Chromo4
世界上體積最小、靈敏度的實時熒光 PCR 儀之一
Chromo4 是一個集成化程度非常高的光學系統。4 通道的激發光由各自不同的LED 發出，而發射光則通過對應的光電二極管檢測。
