Roboz has put out a new catalog designed to assist customers in selecting exactly the right instrument for their needs. While the Dumont #5 forceps remain the best-selling, with dozens of others on offer in a wide range of designs, tip sizes, alloys and finishes, the catalog helps to demystify the process of choosing the best tool.
Alloys, for example, will greatly change the physical characteristics of forceps. Carbon steel is one of the hardest materials used for forceps, rating a 60 on the Rockwell scale, which makes them durable, but their very hardness causes them to be more brittle than those made with other materials, and more susceptible to rust.
Inox, a special brand of stainless steel that has good stain resistance, is also a hard alloy, but is softer than pure carbon steel, resulting in instruments whose tips are more flexible and thus less prone to breakage.
A relatively soft alloy – Rockwell 37 at the tips – is titanium, which is lightweight, flexible, and exceptionally resistant to corrosion, making it ideal for experiments done in saline solutions. Titanium can withstand heat above 400 degrees Celsius without deforming and is absolutely non-magnetic.
The increased stain and corrosion resistance over Inox makes Dumoxel a very popular alloy. It is softer than Inox, making forceps tips more flexible, and like Titanium it is resistant to extremely high temperatures.
Dumostar is an alloy which combines the best characteristics of the others. A mix of steel, nickel, cobalt and molybdenum, Dumostar resists temperatures over 500 ˚C, is completely non-magnetic, and even though it is a very hard alloy (Rockwell 62), Dumostar tips can flex a great deal more than other alloys without permanent deformation. Its optimal resistance to all forms of corrosives, including organic and mineral acids and salt, make it the best choice in many areas of biomedical research.
Most designs are available with different-sized tips, a fine and a standard. The fine – called “biology” – are recommended for medical work. However, the dimensions of “biology” tips are different for each instrument pattern.
In addition, a number of finishes are available. Polished instruments, for example, are more corrosion resistant and easier to clean. Matte or non-reflecting finishes are convenient for working under a microscope. The Dumont #5 forceps are available with a ceramic coating, which offers increased hardness, corrosion resistance, and thermal insulation. It also prevents electrostatic discharges and metal contamination.
With so many choices, the new Dumont catalog provides clear, easily-understood guidelines to steer customers in the right direction, offering detailed information on alloys, finishes, and other key aspects. Products are shown in table format, making it easy to review the differences in dimensions, material, and price at a glance. The Dumont forceps catalog is available for download from the company's website.
