Dumont produces high quality handmade tweezers, and has gained the popularity of all researchers over the years. Developed in 1875 by Arnold Dumont in La Sagne, Switzerland. There is a variety of material which is used to make Dumont tweezers, is shown below:
- Biological Grade: Made from Dumoxel steel, the highest quality steel that is available. These tweezers have very fine points, they are non-magnetic, and anti-corrosive. They are the most reliable for all of your precision work.
- High Precision Grade: Made from (Inox) stainless steel, these tweezers have fine points and they can be used as a substitute for Biological Grade when non-magnetic tweezers are not required.
Dumoxel is composed of C, Cr, Ni, Mo and Cu and is the most popular alloy among our customers. This alloy was developed and patented by Dumont to offer the best in resistance to corrosion thanks to its high concentration of molybdenum and chromium. Dumoxel also guarantees an excellent resistance to sulphuric environments, hydrochloric acid, as well as to all other mineral and organic acids. Dumoxel is 95% antimagnetic, resistant up to temperatures of around 400° C (DIN 50 914) and is suitable for autoclave sterilization at 270°C.
This Dumont patented alloy is composed of C, Cr, Mo, Mn, Co, Ni and Si. Dumostar is more elastic and more resistant to corrosion than the best stainless steels. It is also perfectly compatible with human tissues and is resistant to mineral and organic acids as well to salt. Although slightly more expensive than other alloys, Dumostar is 100% antimagnetic and is resistant to sterilization temperatures of up to 500°C.This is the most cost effective and appropriate alloy for laboratory use.
