Why ZTIP Brushes are Better

The Z-Tip Difference… It Changes Everything

Traditional methods of putting protective tips on medical brushes are flawed. That’s why we created the Z-Tip — a revolutionary new protective brush tip for endoscope cleaning brushes and cytology brushes that is superior to any brush available anywhere.

Z-Tip v. Insert Molded Tips

Before the Z-Tip, a popular protective brush tip was the Insert Molded Tip.  Insert Molded Tips are made by placing the end of a twisted wire brush into an injection mold.   Problems with injection molded brush tips include:

  • Detachment: The tip can fall off the twisted wire brush, causing scratching, poking and scarring.
  • Protrusion: The core wire might protrude through the plastic surface which can cause scratching, poking and scarring.
  • Orientation: The tip orientation can be inconsistent.
  • Expense: The manufacturing process is expensive, requiring costly molds and prolonged development time.

The Z-Tip fixes these flaws, because:

  • The Z-tip cannot become separated from the brush, because the tip is formed from the wire itself.
  • The brush and tip is one metallurgic unit.
  • It is impossible for the wire to protrude through the tip, because the wire is melted and reformed into the tip.
  • Our fully automated inline manufacturing process ensures that the tip is of the same size and orientation every time.
  • The Z-Tip is manufactured inline with the twisted wire brush in an automated process which keeps the cost down.
  • It has a smooth, mirror-like surface.
  • Because the brush and tip are one unit, the Z-Tip twisted wire brush is stronger. The bristles will not dislodge under force.
  • Since the core wire and Z-Tip are the same material, there are no biocompatibility issues.
  • The Z-Tip reduces internal inspection time and costs due to its quality and consistency.
  • Because it cannot scar, the Z-Tip enhances endoscope sterility by not allowing grooves that trap contaminants.

Z-Tip v. Light Cured Acrylic Tips

Light Cured Acrylic Tips are another traditional type of protective brush tip.  They are made by dipping the end of a twisted wire brush into plastic or acrylic and using ultraviolet light to cure the substance into a tip.  Defects can include:

  • Protrusion:  The core wire can protrude through the acrylic surface which may cause scratching, poking and scarring.
  • Rough surface:  The surface texture might be rough.
  • Inconsistency:  Tip dimensions can be inconsistent.
  • Petroleum-based:  The manufacturing process involves hazardous fumes, extended curing times and is petroleum-based.

The Z-Tip corrects these defects, because:

  • The Z-Tip surface is smoother, stronger and safer than the acrylic surface.
  • The Z-Tip is formed by actually melting the end of the twisted wire and reforming it into the tip which makes core wire protrusion impossible.
  • With our automated inline manufacturing process, dimensions are the same every time.
  • No petroleum is used in making the Z-Tip other than powering the equipment.

Z-Tip v. Hand Crimped Tips

An old but still popular type of protective brush tip is the Hand Crimped Tip.  These are made by pressing small metal caps onto twisted wire brushes by hand.  Weaknesses include:

  • Detachment:  The tip can fall off the twisted wire brush and cause scratching, poking and scarring.
  • Orientation:  Due to the manual process, the placement of the tip on the twisted wire brush may be inconsistent.
  • Expense:  This is a manual and expensive manufacturing process.

The Z-Tip offers these answers:

  • It is impossible for the Z-Tip to become separated from the brush, because the brush and tip are one metallurgic unit.
  • It is not possible for the core wire to protrude through the tip.
  • Z-Tip twisted wire brushes are lower cost, because they are manufactured in an efficient, fully automated process.

Z-Tip v. Fan Tipped Brushes

The Fan Tipped Brush is one of the original attempts at creating protective brush tips, and it is still used today.  This is a brush where the bristles are “fanned” to provide aimal level of protection.  These brushes have several serious problems…

  • Inadequate Protection:  The fanned bristles are simply not adequate protection from scratching, poking and scarring.
  • Wire Exposure:  The core wire can easily become exposed.
  • Limitations:  Fan tips cannot be made in all diameters commonly needed for medical twisted wire brush applications.

The Z-Tip solves these problems, because:

  • The Z-Tip is manufactured using high energy fusion welding technologies to melt the end of the twisted wire brush into a consistent, smooth and inseparable protective tip.
  • The mirror-like surface will not scratch or scar.
  • The Z-Tip is available for all commonly used twisted wire medical brush applications.
