Thermo Scientific Invitrogen Countess 3 Automated Cell Counter

The Thermo Scientific Invitrogen Countess 3 Automated Cell Counter is an advanced cell counting and assay device that utilizes high-quality optics and sophisticated image analysis algorithms to evaluate trypan blue stained cell samples in suspension. This innovative system boasts a user-friendly interface, complete with data storage and report generation capabilities, easily transferable to a PC via an included or separately purchased USB drive. Employing disposable Countess Cell Counting Chamber Slides, the device accommodates cell samples in two unique enclosed chambers. This feature facilitates the simultaneous analysis of two distinct samples or duplicate assessments of a single sample. A hallmark of efficiency, the instrument executes a standard cell count in the brightfield channel within a rapid 10-20 second timeframe per sample, accommodating an extensive range of eukaryotic cells. Beyond mere cell enumeration and viability, the Countess 3 Automated Cell Counter delivers valuable insights on cell size, making it an indispensable tool for comprehensive cell analysis.

All of our equipment is in excellent condition and will be fully tested to perform at factory specifications before being shipped.

INCLUDED:
The Thermo Scientific Invitrogen Countess 3 Automated Cell Counter includes:

> Phosphate-buffered Saline Calibration & Countess Test Beads Validation Report
> 10 Countess Cell Counting Chamber Slides
> Power Cord
> Full 180 Day Parts and Labor Warranty

Cell Counter Inspection and Recertification Checklist

Verify machine software initialization to ensure complete and accurate startup
Examine display screen for cracks, dead pixels, or other damage that may affect visibility
Test touch screen functionality, confirming sensitivity and accurate response
Inspect slide port for proper alignment and any visible signs of wear or obstruction
Examine internal wiring for secure connections and any signs of damage or wear
Clean internal casing to maintain optimal equipment hygiene and prevent dust buildup
Prepare a test sample using a precise 10µL mixture of cell suspension fluid and Trypan Blue stain
Conduct Phosphate Buffered Saline calibration and validate with Countess test beads, if applicable
Confirm concentration accuracy of test beads, ensuring results align with specified standards
Verify zoom, brightness, and focus controls are fully functional for optimal image clarity
Test USB port functionality, saving test results and images to verify data transfer
Inspect packaging of disposable chamber slides for any tears, punctures, or contamination
Verify power supply output for correct voltage delivery to all components
Compile a comprehensive calibration report, detailing all verification and validation results
