The Countess 3 Automated Cell Counter is a benchtop cell counting system equipped with
an advanced machine-learning algorithm, ruggedized optics, fully-automated focus and
lighting, and image analysis software for rapid assessment of primary and immortalized cell samples
• Accurate—eliminates the subjectivity of manual cell counting and user-to-user variability
• Fast—counts live and dead cells, measures viability, and reports average cell size with a single touch in about 20 seconds
• Convenient—requires no cleaning or routine maintenance; flush-mounted high-resolution
capacitive touchscreen and simple user interface provide quick startup, require minimal training,
and offer automatic saving of data to USB or cloud
The Countess 3 Automated Cell Counter works in two simple steps:
1. Mix 10 µL of sample with 10 µL of trypan blue and pipet into a disposable Countess chamber slide.
2. Insert the slide into the instrument. Rapid Capture and Auto-Save modes allow cell counting with
a single touch. Focus, lighting, and file saving are executed automatically.
Get accurate cell counts
The Countess 3 Automated Cell Counter uses trypan blue staining combined with auto-focus and
lighting driven by a machine-learning image analysis algorithm to obtain accurate cell and viability counts.
The measurement range extends from 1 × 104 to 1 × 107 cells/mL (the optimal range is 1 × 105 to
4 × 106 cells/mL), which is broader than that of a hemocytometer.
Transfer data and images to your PC or cloud
Using the USB port on the Countess 3 Automated Cell Counter and any USB drive, you can save
your cell count results and images and transfer them to your PC. For your convenience,
a USB drive is supplied with the Countess 3 instrument and a WiFi dongle is available

由于传统的血球计数板已不能满足高速发展的细胞研究需要，市场上各种自动细胞计数的设备越来越多。常见的主要分为两类：基于图像的细胞计数仪(Automated vision-based counter)和基于库尔特电阻抗原理的细胞计数仪。两者主要区别在于，前者扫描仪器视野内图像，依靠设定的上下限细胞大小来进行图像识别，而后者根据 细胞通过小孔引起电位变化来计算细胞个数（关于库尔特原理，详见此处），两者原理不同，因此所获得的效果也大相径庭。以下对各类细胞计数仪的计数准确性、可重复性、快捷性做
