Overview

The CleanCut90™ PEEK Tubing Cutter is designed to produce clean, square cuts in PEEK tubing used in chromatography systems. Over time, normal use can dull the blade, resulting in reduced cutting performance and less precise tubing ends.

Replacing the blade when it becomes worn helps maintain clean cuts and reliable tubing connections.

Before You Begin

Exercise caution when handling cutter blades.

Recommended precautions include:

• Wearing appropriate hand protection.
• Handling blades only by their non-cutting surfaces.
• Working on a clean, stable surface.
• Keeping replacement blades in protective packaging until needed.

Step 1: Remove the Stainless Steel Retaining Pin

The blade is secured inside the cutter by a stainless steel retaining pin.  Using an appropriate tool, carefully push the pin out of the cutter body.

Important considerations:

• The pin is press-fit into place.
• Moderate force may be required.
• The pin will not typically slide out freely.
• Take care not to damage the cutter body during removal.

Step 2: Remove the Existing Blade

Once the retaining pin has been removed:

• Carefully remove the worn blade.
• Inspect the cutter body for debris or damage.
• Clean the blade area if necessary.

Proper cleaning can help ensure smooth installation of the replacement blade.

Step 3: Install the New Blade

Position the replacement blade in the same orientation as the original blade.

Verify that:

• The blade is fully seated.
• Alignment matches the cutter design.
• The retaining pin holes are properly aligned.

Correct positioning is important for achieving precise tubing cuts.

Step 4: Reinstall the Retaining Pin

Reinsert the stainless steel retaining pin through the cutter body and blade assembly.

Ensure:

• The pin is fully seated.
• The blade moves properly within the cutter mechanism.
• No components are loose.

The cutter should now be ready for normal operation.

Verify Proper Operation

Before returning the cutter to service:

• Inspect the blade installation.
• Make a test cut on suitable tubing.
• Confirm the cut is clean and square.
• Verify smooth cutter operation.

A properly installed blade will help produce consistent tubing cuts for chromatography applications.

Benefits of Timely Blade Replacement

Replacing worn blades helps:

• Maintain clean tubing cuts
• Improve fitting connections
• Reduce tubing deformation
• Minimize dead volume issues
• Improve chromatography system performance

Well-prepared tubing ends are essential for leak-free, low-dead-volume fluidic connections.

Key Takeaways

• The blade is secured by a press-fit stainless steel retaining pin.
• Moderate force may be required to remove the pin.
• Remove the old blade and install the replacement blade in the same orientation.
• Reinsert the retaining pin to secure the blade.
• Test the cutter after installation to verify proper operation.
