Cell Counter
Free!
A multi-key manual cell counter for fast white blood cell differentials at the microscope. Each key tracks a cell category while the totalizer records progress. It is reliable, low cost, and easy to read. Smooth keys, audible alerts, and stable construction reduce errors and fatigue. Ideal for clinical labs, teaching programs, and backup use alongside automated analyzers. Buy it to keep slide reviews accurate, traceable, and efficient every shift.
Description
A cell counter is a manual, multi-key tally device used to perform differential counts of white blood cells on stained blood films. Each key corresponds to a cell type, while the totalizer records the cumulative count. Technologists press the appropriate key as they review fields under the microscope, producing quick, auditable results for routine differentials and slide reviews. The sturdy housing, clear windows, and positive-action keys support fast, error-resistant work at the bench.
Key features and benefits:
-
8–12 category keys plus a running total for quick differentials
-
Audible signal at preset totals to prompt field changes and QC checks
-
Smooth, low-force keys that reduce fatigue during long sessions
-
Dual reset knobs to clear individual channels and the totalizer
-
Anti-skid base and compact footprint for stable, one-hand use
-
High-contrast numeric display for easy reading and recording
-
Durable body for classroom, clinic, and outreach settings with limited power
Typical applications:
-
Routine WBC differential counts in hematology labs
-
Slide reviews to verify abnormal analyzer flags
-
Training and competency assessments in teaching programs
-
Backup counting during downtime or in resource-limited sites
How it compares:
-
Versus automated analyzers: lower cost, no warm-up or calibration, and immediate use at the microscope; ideal for verification, rare cell notes, and troubleshooting.
-
Versus single-button tally counters: multiple channels and a totalizer deliver organized, traceable results.
Quality notes:
-
Supports good laboratory practice with clear totals suitable for worksheets and LIS entry.
-
Methods should align with institutional hematology procedures and regional guidelines.
A dependable manual cell counter keeps differentials accurate, documented, and fast without relying on power or complex setup.
