Introduction
An automated cell counter is an instrument for automatically counting living and/or dead cells. Researchers opt for automated cell counters compared to manual hemocytometers, which have been used to count cells for decades since they deliver faster and more accurate cell counts. An automated cell counter can deliver a count in less than 9 seconds in the bright field mode compared to the 5 minutes manual counting would take.
An automated cell counter can measure cell concentration before cell passage or evaluate the cell viability of a cultured cell line. Conduct Science’s automated cell counter allows easy operation of brightfield and fluorescence cell counts. It also has multiple data displays and storage, which furthers its convenience.

Applications
Medical and research laboratories employ automated cell counters to assess the quantity and kinds of cells present in blood or urine samples and verify the viability of a cultivated cell line for research purposes.
The automated cell counter is highly efficient in counting deferential neutrophil counts, with moderate efficiency in counting lymphocytes and less efficiency in monocytes and eosinophils counting (von Konigslow, Renaud, Duffield, Higginson, & Kelton, 2019). The countermeasures cells of body fluids with precision, improved accuracy, and efficiency is extremely difficult with manual counters (Bourner et al., 2014).

Strengths and Limitations
Strengths
Automated cell counting is quicker, less reliant on the user, and simple to use. The device has a large data storage, allowing 1000 counts to be stored. Moreover, it allows multiple data displays and storage with the data access allowed from any location, at any time.
It can count various types of cells that include cell lines, stem cells, beer yeast, primary cells, and pollens with the accuracy in size ranging from 4 microns to 60 microns. It only weighs 3.2 kg, which makes it easy to carry anywhere. In terms of safety, there is no hazardous biological damage as it comes with disposable slides.
Using it at a comfortable angle of 45 degrees reduces eye fatigue and spine pain. A built-in dilution calculator makes the work quicker and less tedious. Users can preset functions according to their needs; they can adjust cell size, roundness, and brightness which makes it more accurate. It can store data in different formats, i.e., PNG, PDF, CSV, and JPEG.
Limitations
Automated hematology analyzers may inadvertently exaggerate or deflate cell counts. They solely measure the volume and amount of particles. Certain analyzers, particularly impedance-based counters, may not distinguish between minute aggregates of platelets and nucleated red blood cells. Platelet clumping may be mistaken for leukocytes or erythrocytes, and nucleated red blood cells, especially lymphocytes, can be mistaken for leukocytes. Atypical cells that are big or unidentified, toxic immature neutrophils, and significantly reactive lymphocytes may also be misclassified.
Precautions
- Use the Counter within each model's ambient operating temperature, humidity, water, and oil exposure specifications.
- For each model, save the Counter with the set temperature range. Allow at least 3 hours for the Counter to come to room temperature if kept at a temperature below 10°C.
- Do not use the Counter in places with a lot of stress and vibration; long-term use in such settings might cause damage to the Counter.
- When switching a load, magnetic contactors produce a shock of 1,000 to 2,000 m/s2. Separate magnetic contactors from the Counter when mounting to DIN Track to avoid vibration and stress. Rubber with anti-vibration properties should be used.
- Organic solvents (benzene or paint thinner), strong alkalis, or strong acids should not be used since they will harm the Counter's exterior conditions.
- Keep the counter as far away from static electricity sources as possible.
- Condensation inside the Counter might cause malfunction or damage to the Counter's components.
- Depending on the operational climate, resin and rubber components (such as rubber packaging) may degrade, shrink, or harden (e.g., subjected to corrosive gases, ultraviolet light, or high temperatures). Periodic inspection and replacement are recommended.
Summary
- Automated cell counters are instruments for automatically counting living and dead cells in culture. They count suspension, adherent, and aggregated cells.
- They deliver faster, simpler, and more reliable cell counts at difficult-to-estimate concentrations than manual counters.
- Automatic cell counters may be self-contained (internal PC) or linked to an external computer.
- It allows the performance of image-based cell counts and also has an option for fluorescence analysis.
- It can accurately count cells with sizes ranging between 4-60 microns and concentrations ranging between 104-107 cells/mL.

How It Works
The automated cell counter employs digital image analysis of cells suspended in a defined volume within disposable counting slides. The 2.5X optical magnification system with 5.0 megapixel resolution captures high-definition images of the 2.15 mm × 1.62 mm counting area. The instrument's image processing algorithms identify individual cells based on size parameters (4-60 μm diameter) and morphological characteristics, distinguishing viable cells from debris and cell aggregates.
Fluorescence capabilities utilize three excitation/emission wavelength combinations: 375/460 nm for DAPI-type nuclear stains, 480/535 nm for FITC-compatible dyes, and 540/620 nm for propidium iodide or similar viability indicators. The system integrates both manual and autofocusing mechanisms to optimize image clarity across different cell types and suspension densities. Cell concentration calculations account for the precise counting area volume and dilution factors when applicable.

Practical Tips
Verify counting accuracy monthly using certified reference beads of known concentration within your typical working range.
Why: Regular validation ensures measurement traceability and identifies any drift in counting performance.
Clean the slide insertion area daily and optical components weekly using lint-free lens tissue and appropriate cleaning solutions.
Why: Optical cleanliness directly impacts image quality and counting accuracy, particularly for smaller cells near the detection threshold.
Prepare duplicate samples for critical experiments and compare results to assess measurement variability.
Why: Biological samples can exhibit heterogeneity that affects counting statistics, and duplicate analysis improves data confidence.
If counts appear consistently low, check for cell settling in the suspension and ensure gentle mixing before slide loading.
Why: Cell sedimentation can result in non-representative sampling and underestimation of true cell concentration.
Review captured images for debris, aggregates, or atypical morphology before accepting counting results.
Why: Visual verification of automated analysis helps identify sample preparation issues or instrument performance problems.
Handle fluorescent dyes according to manufacturer safety data sheets and dispose of counting slides as biohazardous waste.
Why: Fluorescent reagents may pose health hazards, and used slides contain biological material requiring proper disposal protocols.
Document cell passage numbers and culture conditions when storing counting data for experimental traceability.
Why: Cell behavior can change with passage number, and comprehensive documentation supports reproducible experimental protocols.
Adjust focus manually if autofocus struggles with samples containing high debris content or unusual cell morphology.
Why: Manual focus control provides better optimization for challenging samples that may confuse automated focusing algorithms.
