mastering reproducibility in cell counting

Reproducible cell counting is a critical foundation for reliable life science research, yet variability introduced during sample preparation and analysis continues to undermine data quality across many workflows.

This application-focused eBook explores how workflow design, consumable engineering, and modern automation can dramatically reduce variability in cell counting and viability assessment, supporting confident, reproducible results across a wide range of cell types and applications.

Using all‑in‑one slide technology alongside advanced automated cell counters as practical examples, this guide highlights how minimizing manual steps such as pipetting and staining can improve consistency, save time, and reduce operator-to-operator variation.

Flow Cytometry / Cell CountingFlow cytometers are used to count, sort and examine multiple characteristics of cells. Other cell analysis equipment includes image cytometers, cell counters, fluorescence-activated cell sorters (FACS), magnetic-activated cell sorters (MACS), and a range of flow cytometry assay kits. Flow cytometers can reveal information on cell viability, cell proliferation, apoptosis and cell cycle progression, as well as identify cell populations and intracellular or cell-surface molecules. Additionally, some flow cytometers, known as FACS, have an additional sorting function after analysis. Cell counters and image cytometers count live and dead cell populations and can also conduct cell proliferation assays.
