Great equipment.
Rating: 4.7

  • Application Area: Automatic cell count

"The equipment is really handy and easy to use. It performs the task of counting live as well as dead cells in a fraction of a few seconds. It also provides images of the cells counted. Data can be stored on machine or transferred to a computer."

Good tiny machine. Work great with most of the cell types with some limitations.
Rating: 4.3

  • Application Area:count cell

"Countess II is very easy to use and it's a small machine for the bench top. It's as simple as adding a 1:1 ratio of typhon blue (5ul) and your sample (5ul). You mix and pipet onto the plastic slide, wait 30 sec, then insert the plastic slide into the machine. You get the result of adjusted concentration and viability % of the live and/or dead cell of the sample. However, the limitation is that the cell size has to be in certain range. If it's too small, the readings won't be accurate. Also, it won't be accurate if it contains more than one type of cell."

Definitely worth the money!
Rating: 5.0

  • Application Area:Tissue Culture

"This has made our life in a massive teaching lab so much easier. Not having to manually count cells using a haemocytometer several times a week makes having this worth the money. The task that took us a several minutes to do now takes merely a few seconds. The instrument is very easy to use and quite small as well so doesn't take up much space."

Great results, cant live without this instrument.
Rating: 4.0

  • Application Area:Counting cells

"The instrument is very simple to use and user-friendly platform, mix your cells with trypan blue and load the samples to the slides and inserted. It will give the results like less than 30 sec and more accureate."

Very useful in cell culture and when you work with a lot of cell lines. I love it.
Rating: 4.3

  • Application Area:Determination of cell number in cell cultures.

"This equipment is very useful in the laboratory, especially when you work with many cell lines at the same time. You can count cells very fast and save time. Also, this machine is very accurate in the determination of the cell number in culture and results are very reproducible."

  • Application Area:cell counting

"Easy to use, could provide consistent counting instead of manual."

Review date: 27 Jul 2017 | Countess™ II Automated Cell Counter

The new Countess™ II 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.

Accurate - use the Countess II Automated Cell Counter to eliminate the subjectivity of manual cell counting and user-to-user variability

Fast - the Countess II Automated Cell Counter provides a total cell count, reports viability, and measures average cell size in as little as 10 seconds

Convenient - the Countess II Automated Cell Counter requires no cleaning or routine maintenance. A capacitive touchscreen and simple user interface provides quick startup and requires minimal training.

The Countess II Automated Cell Counter comes with:

  • Countess USB drive for storing and transferring data to your computer
  • Disposable slide holder
  • Power cord and 4 plug adaptors to accommodate most countries
  • Quick reference card (QRC)
  • A free box of 50 disposable slides

The Countess II Automated Cell Counter works in 3 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.
  3. Press the "Count" button.

Get accurate cell counts:
The Countess II 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.

Transfer data and images to your PC:
Using the USB port on the Countess II 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 instrument).
