Dumont Tweezers - Material Properties

Dumont works closely with Swiss suppliers of raw materials to ensure that its products are of optimal quality. High-quality raw materials are a vital element of our manufacturing process.

  • Carbon steel extremely hard steel alloy (>59 HRC) 
  • Inox 02 standard stainless steel
  • Antimagnetic steel non-magnetic and good resistance to corrosion
  • Dumoxel non-magnetic and strongly anti-corrosive, softer than Inox
  • Titanium light, resistant, non-magnetic alloy
  • Brass common in watch-making
  • Nickel doesn’t damage the piece you handle
  • Inox 08 medical grade stainless steel
  • Dumostar non-magnetic cobalt rich stainless steel alloy

 The different materials can be finished in various ways including:

Epoxy-coated tweezers, excluding tips, gives extra thermal (up to 120°C) and electric insulation (up to 220V). Coating is safe and exceptionally resistant to solvents, acids and saline solutions, less so with strong caustics.

Vulcanised Nitrile Rubber grip tweezers have soft electro static discharge (ESD) grips that are also ergonomic to hold.

Metal polishing grades from the highest polishing, mirror polish to polished and then matte finish.

Medical grade usually have serrated finger grips and a particularly fine surface finish. Some types are mirror-polished, but most matte finish. The medical finish is available in just a few styles.

Care & Handling of Dumont Instruments

  • Rinsing: Immediately after use, rinse instruments under warm running water to remove all material. Instruments should be submerged in a solution of water and neutral (pH of 7) detergent until they can be cleaned.
  • Manual Cleaning: Use stiff plastic cleaning brushes and neutral (pH of 7) detergents only, never use steel wool or wire brushes. Brush delicate instruments carefully and handle separately from general instruments. Rinse and inspect.
  • Ultrasonic Cleaning: Place instruments in open position, separate instruments and don't place dissimilar metals in the same cleaning cycle. All instruments must be fully submerged and processed for 5-10min. Rinse with water.
  • Sterilisers: Always follow manufacturer’s recommendations. Be sure to lubricate instruments after last rinse cycle and before sterilisation cycle.
  • Autoclaving: Lubricate all instruments with metal-to-metal action such as scissors, haemostats, needle holders, self retaining retractors using surgical instrument lubricants only. Never lock an instrument during autoclaving and do not overload the autoclave chamber. Run dry cycle for the period recommended by the autoclave manufacturer with the door open ~20mm to avoid condensation on opening.
  • Cold Sterilisers: This can require a 10-hour immersion to render instruments sterile which may be detrimental to surgical instruments. Acceptable disinfection can take place in 10mins, autoclaving is recommended to render the instruments sterile. Tungsten carbide inserts (needle holders, scissors, tissue forceps) will be destroyed by solutions containing benzyl ammonium chloride.

After cleaning let instruments air dry and store them in a clean and dry environment.
