Introduction

Product Technology

DeNovix CellDrop

cell counters are compact instruments with integrated processors and high-

resolution touch screens. The software utilizes application specific icons along with a custom operating

system to provide an intuitive, easy-to-use instrument for cell count measurements.

The pre-configured app settings are factory optimized for ease of use. The software allows the user to

customize settings when needed to meet lab specific workflow preferences.

The CellDrop uses three chamber heights to enable cell counts over a wide dynamic concentration range

according to specifications. This innovative and patent-pending technology along with user-defined

protocols allows users the flexibility required for today’s cell culture workflows.

This User Guide is designed for both CellDrop BF (Brightfield only) and CellDrop FL (Dual Fluorescence

plus Brightfield) owners. Several applications and software features are only applicable for instruments

with Fluorescence mode (CellDrop FL) and do not apply to the CellDrop BF.
