1、 Product operating principle:

(1) Countess disposable cell counting board provides morebigThe convenience of limitations, Countess3 cell counter can achieve sustainability and cost reduction by reusing counting plates. Enjoy the speed and convenience brought by automation and counting performance.

(2) The Countess3FL fully automatic fluorescent cell counter is compatible with reusable counting boards and features flexible fluorescence and bright field dual-mode cell counting.

(3) The InvitrogenCountess3FL fully automatic cell counter has fluorescence function and can select two easily replaceable fluorescence cubes from 14 spectral range options. Like the Countess3 cell counting instrument, the Countess3FL fully automatic fluorescent cell counting instrument can also count cells and detect activity in the bright field. Using fluorescent reagents, it can also report fluorescent protein expression, apoptosis, transfection efficiency, and cell activity in just 30 seconds.

(4) The fluorescent cell counter also allows for the use of fluorescence based cell detection, which has stronger specificity for complex samples by using fluorescent cell dyes or fluorescent labeled cells.

2、 Common characteristics:

The common features of Countess3 and Countess3FL cell counters are accuracy, speed, simplicity, and automation;

Provide cell viability assays and single-cell data;

Compatible with reusable counting boards;

Optional software that supports compliance requirements for electronic records in 21CFR Part 11.

3、 Countess3 uses trypan blue for cell viability assay:

Use Countess3 fully automatic cell counter to count mouse PBMCs that are small in size, low in concentration, and usually difficult to count. In this bright field counting, 0.4% trypan blue staining was used to distinguish activity, with live cells remaining semi transparent and dead cells stained dark. The red outline (circle) represents dead cells, while the green outline represents live cells.

The Countess3 series automatic cell counting&analyzer introduces artificial intelligence to improve accuracy to a higher level.

4、 Product Description:

(1) ThermoFisher Scientific offers two high-performance cell counters to meet any laboratory needs.
（2）Invitrogen ™ Countess ™ 3 and Countess ™ The 3FL automatic cell counter utilizes artificial intelligence (AI) and applies deep learning neural network algorithms to achieve high-precision cell counting, even for challenging cell sample types. Our scientists have implanted machine learning algorithms into the system to help you accurately count cells, while also avoiding user to user differences caused by the use of manual hemocytometers.
(3) The Countess3 series automatic cell counter has functions such as automatic light intensity adjustment, automatic focusing, and automatic saving, which can help you save time.

5Countess 3 fully automatic cell counterCharacteristics and advantages:
