Countess™ II FL Disposable Slide Holder
For use with Countess® II FL Automated Cell Counter Only. Holds Countess® disposable slides. Not compatible with the Countess® II FL Reusable Slide (A25750).
Countess™ II FL Automated Cell Counter
The new Countess™ II FL Automated Cell Counter is a benchtop assay platform equipped with state-of-the-art optics, full autofocus, and image analysis software for rapid assessment of cells in suspension. With three-channel flexibility—brightfield and two optional fluorescence channels—researchers can count cells, monitor fluorescent protein expression, evaluate apoptosis, and measure cell viability.
• Accurate—use the Countess II FL Automated Cell Counter to eliminate the subjectivity of manual cell counting and user-to-user variability
• Flexible—the Countess II FL Automated Cell Counter is able to accept up to two EVOS® light cubes that are user-selectable from over twenty fluorescence channels
• Fast—the Countess II FL Automated Cell Counter provides a total cell count, reports viability, and measures average cell size in as little as 10 seconds. Counting speed is identical when using fluorescence channels.
• Convenient—the Countess II FL Automated Cell Counter requires no cleaning or routine maintenance. A capacitive touchscreen and simple user interface provides quick startup and requires minimal training.

Get accurate cell counts
The Countess II FL Automated Cell Counter uses trypan blue staining combined with an auto-focus mechanism and sophisticated image analysis algorithm to obtain accurate cell and viability counts. The measurement range extends from 1 x 10e4 to 1 x 10e7 cells/mL (the optimal range is 1 x 10e5 to 4 x 10e6 cells/mL), which is broader than that of a hemocytometer. The optimal cell size for accurate viability assessment is 7–60 µm, while particles as small as 4 µm can be successfully counted.
Simple operation with fluorescent application versatility
Operated using an intuitive user interface, automated cell counting with the Countess II FL instrument gives you the data you need to prepare your sample for the next passage or experiment, and allows you to multiplex with a variety of fluorescent dyes and proteins excited via EVOS® Light Cubes.
Transfer data and images to your PC
Using the USB port on the Countess II FL Automated Cell Counter, you can save your cell count results and images, and then transfer them to your PC. (For your convenience, a USB drive is supplied with the Countess II FL instrument).

Countess™ Cell Counting Chamber Slides (Invitrogen™)
Les chambres de culture sur lame pour la numération des cellules Countess® sont conçues pour une utilisation avec le compteur automatisé de cellules Countess®. Cet ensemble contient 50 boîtes de lames (50 lames par boîte) et un flacon de 100 ml de bleu de tryptan (0,4 %).
Prêt à l’emploi pour votre confort
Pour votre confort, les chambres de culture sur lame pour la numération des cellules Countess® sont préstérilisées et conditionnées individuellement. Chaque lame comprend deux chambres distinctes et fermées pour compter un échantillon en double ou deux échantillons différents. Les cellules sont comptées dans un endroit centralisé de la chambre de comptage. Le volume compté est 0,4 µl, le même que le comptage des quatre carrés 1-mm2 dans un hémacytomètre standard. Après leur utilisation, les lames Countess® peuvent être mises au rebut avec vos déchets biologiques dangereux courants. Contrairement à un hémacytomètre, vous n’êtes pas tenu de nettoyer les lames Countess® avant ou après leur utilisation.
Le compteur automatisé de cellules Countess® fonctionne en 3 étapes simples :
1. Mélangez 10 µl d’échantillon à 10 µl de bleu de trypan, puis insérez-les par pipette dans une chambre de culture sur lame jetable Countess®.
2. Insérez la lame dans l’instrument.
3. Appuyez sur le bouton de comptage des cellules.
Voilà ! Vous avez le nombre total de cellules, le pourcentage de cellules viables et la taille moyenne des cellules, le tout en moins de 30 secondes.
