Description
Bring Back Sharp Images and Reliable Counts on Your Vi-CELL XR
The flow cell is where every Vi-CELL XR measurement happens. Each sample is pumped through the flow cell and imaged, and the software counts live and dead cells in a known volume set by the flow cell’s depth. When the flow cell is scratched, etched, stained or cracked, images lose clarity, background rises, and counts and viability stop being trustworthy.
This complete replacement kit gives you everything needed to restore your Vi-CELL XR’s optical path in-house: a new flow cell, new tubing and clamps, an installation tool, step-by-step instructions, and a certificate stating the measured depth of your specific flow cell for calibration.
Beckman Coulter has said Vi-CELL XR service and support are expected to continue only through December 2027. This kit lets your lab keep doing the most important XR optical repair without waiting for a field service visit.
Signs Your Flow Cell Needs Replacing
- Blurry or hazy images that don’t improve with cleaning or focus adjustment
- Scratches, etching, permanent stains or debris you can see in the images
- High background or debris counts with clean samples
- Cell counts that drift or no longer match controls
- Leaks at the flow cell or its tubing connections
- Cracked or chipped flow cell glass
Try These First
A flow cell is a significant purchase, so rule out simpler causes before replacing it:
- Clean the system. Run several cleaning and decontamination cycles. Protein and dye buildup often clears with cleaning alone.
- Check the syringe. A worn syringe causes bubbles and inconsistent volumes that can look like a flow cell problem. A replacement Vi-CELL XR syringe is far less expensive and worth trying first.
- Check your reagents. Expired or contaminated trypan blue can raise background and debris.
- Run a control. If a concentration control reads out of range after cleaning and a new syringe, the flow cell is the likely cause.

What’s in the Kit
- 1 replacement flow cell for the Vi-CELL XR
- Replacement clamps
- Pre-configured tubing
- Clamp installation tool
- Step-by-step installation instructions
- Certificate with the measured depth of your flow cell, for calibration
Why the Complete Kit Matters
- Measured-depth certificate: the Vi-CELL XR calculates concentration from the flow cell’s depth. Each flow cell is measured individually so you can calibrate accurately after installation.
- New tubing and clamps: old tubing and clamps can be compressed or worn. Replacing them with the flow cell prevents leaks and keeps the new flow cell properly aligned.
- Installation tool and instructions: make the job repeatable for in-house staff, with no service visit required.
- Lower cost: well below OEM parts and field service, with US-based support from people who know Vi-CELL hardware.
Installation
The kit is designed for in-house installation by experienced lab staff familiar with analytical instruments and the Vi-CELL XR. Follow the included step-by-step instructions, enter the measured depth from the certificate during calibration, then confirm performance with cleaning cycles and a concentration control before returning to routine use. We’re available by phone if you need help at any step.

Frequently Asked Questions
Will this flow cell fit my Vi-CELL XR?
Yes. It is a direct-fit replacement for the Vi-CELL XR flow cell and keeps the instrument’s original optical path.
Is this a Beckman Coulter part?
No. It is a compatible replacement supplied by Cell Viability Inc. Vi-CELL is a registered trademark of Beckman Coulter, Inc.
Why does the flow cell come with a depth certificate?
The Vi-CELL XR uses the flow cell depth to calculate cell concentration. Entering the measured depth from the certificate during calibration keeps your counts accurate with the new flow cell.
Do I need a service technician to install it?
No. Experienced lab staff can install it using the included tool and instructions. If you aren’t comfortable working inside the instrument, call us to talk it through first.
How often does the flow cell need to be replaced?
It depends on use and sample type. Many flow cells last for years with regular cleaning. Replace it when cleaning no longer restores image clarity, or if it is scratched, cracked or leaking.
Should I replace the syringe at the same time?
If the syringe is more than a year old or shows any wear, replacing both at once is a cost-effective way to restore the full fluid path in one maintenance session.
Can I get parts and support after Beckman ends Vi-CELL XR service in 2027?
Cell Viability Inc. plans to keep supplying Vi-CELL XR parts and reagents for the installed base. Call 1-800-618-7660 or email sales@CellViability.com.
Does the kit include everything needed for installation?
Yes. The kit includes:
- Flow cell
- Clamps
- Tubing
- Clamp tool
- Installation instructions
- Flow cell depth certificate
This ensures a complete replacement without needing additional parts.
Do I need a service technician to replace the flow cell?
No. The kit is designed for in-house installation by trained lab personnel. The included clamp tool and instructions simplify the process and reduce downtime.
Why replace clamps and tubing along with the flow cell?
Clamps and tubing are wear components that can affect sealing and fluid flow. Replacing them at the same time:
- Improves system reliability
- Prevents leaks or flow inconsistencies
- Ensures proper alignment of the new flow cell
Will replacing the flow cell improve my results?
Yes. A new flow cell can restore:
- Accurate cell counts
- Reliable viability measurements
- Clear imaging and proper focus
Is this an OEM (Beckman Coulter) part?
No. This is a compatible replacement kit, designed to provide equivalent functionality at a lower cost.
