Tungsten Carbide Instruments
Five times normal instrument life with Tungsten Carbide!
Why tungsten carbide ?
When you have heavy demands on your surgical instruments, be it scissors, needle holders, or forceps, you should consider the benefits of the working surfaces of these instruments made out of one of the hardest alloys available.
As a rule, performing the same type of work, a tungsten carbide instrument will last up to five times longer. For instance, the cutting edges of a pair of scissors, even when used to cut the toughest tissue, will outlast the regular stainless steel pair of scissors by 5 times. Compare the extra initial cost for these instruments with the length of useful wear and you have a very cost effective solution to your instrument requirements.
The tungsten carbide inlays are either glued or welded into place. Due to the properties of the alloy very particular patterns can be achieved on its surfaces. For instance, the delicate pyramid cross pattern profile on the tungsten carbide surfaces of needle holders will hold suture needles much more securely.
Titanium Instruments
Are you using your surgical instruments in a very corrosive environment?
Do you require a completely nonmagnetic instrument for your investigations?
Do you want a very light instrument for hours of fatigue free handling of delicate particles?
Solutions for these and many other problems often encountered in research laboratories can be found in Titanium.
Elemental titanium (TI) is a very strong lustrous white metal, less than half as heavy as steel, with a specific gravity of 4.54. It has a very attractive strength to weight ratio. Titanium and titanium alloys readily form stable protective surface layers, which give them excellent corrosion resistance in many environments, including oxidizing acids and chlorides. Titanium alloys can be heated up to 440° C (824° F).
For use in surgical instruments, titanium is alloyed with 6% aluminum and 4% vanadium. It is extremely difficult to machine and finish, explaining the premium price of the finished product.
is immune to corrosive attacks by saltwater, laboratory saline solutions, blood and other bodily fluids, chlorides, oxidizing acids, alkalis etc.
has a better weight to strength ratio than stainless steel, making your instruments over 40% lighter than the equivalent instrument in stainless steel, with better flexibility and strength and providing less user fatigue
is 100% nonmagnetic, a great benefit when working with nerves, as one example
has a heat tolerance of up to 440° C, or 824° F, making heat sterilization a good possibility
due to the unusual and beneficial characteristics of its inherent surface oxide film, exhibits bactericidal and non-allergenic properties
Left Handed Instruments
Left-handed – For the researcher who is predominantly left-handed, FST offers a number of instruments which are specifically designed to assist in this case. FST is indeed proud to offer the largest selection of left-handed surgical instruments to researchers.
About ToughCut Scissors
A technical breakthrough in edge sharpening technique!
This new type of scissors features two unique cutting edges with the ability to cut through the toughest tissue with exceptional ease and accuracy; one blade is honed to razor sharpness, the other is micro serrated, to avoid slippage of tissue during cutting. For extended use, up to 5 times longer, select the ones with two tungsten-carbide cutting edges. Look for the symbol T-C for this type of scissors.
Established in 1875 by Arnold Dumont to make tools for the famous Swiss watchmakers, this family owned company still produces hand made tools whose style has been copied widely, but whose quality cannot be matched.
Manufactures des Outils Dumont S.A., Switzerland
Original DUMONT forceps are recognized the world over for their exceptional quality and durability. During manufacture, the micro structure of the fine rolled steel is carefully preserved during the filing and machining and the flexibility, elasticity and maximum strength are maintained down to the microscopically matched tips. Each forceps is adjusted to give the user a sensitive "feel" of the material being handled. The inner surfaces of the tips are smooth for a gentle holding grip.
When choosing a Dumont forceps, consider:
- the fineness of the tips you require and
- the alloy best suited to your work
The famous Dumont tips:
Standard
The standard Dumont tips are designed for the most exacting work under the microscope. The approximate dimensions of these tips vary with the different forceps. See dimensions given with each item. Slight variation to the given dimensions can occur, as the tips are hand fashioned.
Biologie
The imprint "Biologie" identifies forceps especially produced for the biological sciences. In overall shape and dimension these forceps are identical to the standard styles but have the added feature of tips which are approximately twice as fine.
Dumont's finest tips
We are frequently asked for the Dumont forceps with the finest tip.
Alloys
Carbon
will stand hard use of the tips but has the disadvantages of staining easily and being highly magnetic. Do not autoclave!
Inox
is an alloy which has a certain amount of chromium added to carbon steel. This results in some loss of hardness but offers good stainless qualities. Inox forceps are magnetic.
Dumoxel
is a patented Dumont alloy which provides optimal stainless steel features while still retaining adequate hardness. This combination makes it the most requested type of metal in Dumont forceps. Dumoxel is nonmagnetic.
Titanium
forceps have several distinct advantages. They are fully corrosion resistant. For instance, salt water is non-reactive to this alloy. Although not as hard as Inox, it is a more flexible metal. It is also 40% lighter than stainless steel, giving greater mobility with less user fatigue. Titanium forceps are 100% nonmagnetic and heat resistant to temperatures up to 440° C (824° F)
Dumostar
After years of research and testing, Dumont has developed this advanced alloy for the express purpose of maintaining fine tips. Made of 40% Cobalt, Dumostar is much more durable and elastic than the best stainless steels. It has a very high resistance to corrosive solvents such as sea water and strong acids and also has a temperature resistance of up to 550°C (1022°F). FST has tested Dumont's alloys in everyday use by some of our best customers and found Dumostar forceps to last, on average, four times longer than Dumoxel and Inox. We believe that, despite it's higher initial cost, Dumostar is the most cost effective alloy for the research lab.
Main features
Resistant to fatigue, modulus of elasticity 210,000 MPA
Hardness about 720 Vickers / 61 Rockwell on the tips.
Resistance to high temperatures 550°C max.
Very good resistance to corrosion: sea water, HCl, H3PO4, HNO3, H2SO4;
Its resistance is superior to that of the best stainless steel.
It is fully non-magnetic.
For over 170 years Moria of France has been producing what are universally acknowledged to be among the world's finest surgical instruments. Specific Swedish and German stainless alloys have been selected for the intended end use of the instrument and many hours of highly skilled labor, sometimes under 40x magnification, have gone into every Moria instrument. To be assured of excellence in any group of instruments look for the following items.
We are proud to present selected instruments of superb quality
produced by S&T of Switzerland.
