Dumont Tweezers

Dumont Tweezers

High quality Dumont tweezers are available in a variety of metals.

  • Dumostar – Anti-magnetic, Dumostar is more elastic and more corrosion-resistant than the best stainless steel
  • Dumoxel – Extremely flexible, Dumoxel is 95% antimagnetic and stain resistant
  • Stainless Steel – Standard metal for most surgical instruments
  1. Dumostar Tweezers
    Dumont Dumostar Tweezers are made of patented Dumont steel. It is highly resistant to metal fatigue, has great elasticity and is durable. It is resistant to mineral and organic acids and salt, autoclavable, and it is more likely to break than to bend. NOTE: WPI surgical instruments are for laboratory research applications. They are not certified for use on humans.
  2. Dumoxel Tweezers
    Dumont Dumoxel Tweezers are made of patented Dumont steel. They are resistant to staining, but slightly softer and less magnetic than stainless steel. Dumoxel has a higher resistance to corrosion due to its high content of molybdenum and chromium. It is very resistant to sulfuric acid, hydrochloric acid and other mineral and organic acids. It is autoclavable, and it is more likely to bend than to break. NOTE: WPI surgical instruments are for laboratory research applications. They are not certified for use on humans.
  3. Stainless Steel Tweezers
    Dumont Stainless Steel is also known as Inox (from French acier inoxydable, a synonym for stainless steel). It is used for general purpose surgical instrument. Stainless steel surgical instruments are resistant to corrosion and autoclavable. NOTE: WPI surgical instruments are for laboratory research applications. They are not certified for use on humans.
  4. Titanium Tweezers
    Titanium tweezers by Dumont offer all the benefits of titanium: non-magnetic, low glare, lightweight and durable. See our selection here. NOTE: WPI surgical instruments are for laboratory research applications. They are not certified for use on humans.

Choosing an Alloy for your Application

  Hardness (Rockwell)    Max. Temp.Resistance    Corrosion Resistance    Magnetic
Stainless Steel    55-56    350°C Good Yes
Stainless Steel is also known as Inox (from French acier inoxydable, a synonym for stainless steel). For general purpose use. Good resistance to corrosion. Autoclavable.
Dumoxel    36 350°C Excellent No
Dumont patented steel. Resistant to staining, but slightly softer and less magnetic than stainless steel. Higher resistance to corrosion due to high content of molybdenum and chromium. Very resistant to sulfuric acid, hydrochloric acid and other mineral and organic acids. Autoclavable. More likely to bend than to break.
Dumostar    62 550°C Non-corrosive No
Dumont patented steel. Highly resistant to metal fatigue, has great elasticity and is durable. Resistant to mineral and organic acids, salt. Autoclavable. More likely to break than to bend.
Titanium    37 550°C 100% Non-corrosive No
Completely stain-free, 40% lighter than regular stainless steel, completely non-magnetic, but is also the softest alloy. Can be used on corrosive environment. Autoclavable.
