EM-Tec 1.TI high precision tweezers, style 1, strong fine tips, titanium
High precision titanium tweezers
EM-Tec high precision anti-magnetic tweezers are Swiss-made, precision engineered, high quality tweezers with smooth edges and a superior matt finish to reduce glare. They are particularly suited to precision handing for electron microscopy (EM) preparation and can also be used in wide ranging applications which include: specimen handling and preparation, sorting, precision manufacturing, electronic assembly, watch making, general laboratory, biological and medical applications.
Manufactured from a special low carbon, high strength stainless steel these tweezers exhibit good corrosion resistance to salts, low concentrate acids, solvents, oils and greases. They also have good wear resistance against most materials. Although an anti-magnetic alloy is used for these high precision tweezers, they are not recommended for use in strong magnetic fields or for handling magnets. We would recommend the use of titanium or plastic tweezers in such cases.
Labtech offer 12 different styles of tweezers and a set of five in a protective wallet.

The material used for manufacturing the EM-Tec high precision titanium tweezers is a selected non-alloyed titanium Grade 1.
General remarks:
- titanium grade 1 (non-alloy titanium)
- fully non-magnetisable
- engineering material with an extraordinary combination of properties:
- low density
- strong
- very high melting point
- good cold-form ability, high ductility
- biocompatible material: cell integrity is maintained, no inflammatory response
- good corrosion resistance at room temperature to air and in marine and industrial environments
- generally used where corrosion resistance and high strength-to-weight ratios are primary requirements
- typical applications for these tweezers include electron microscopy (SEM and TEM) medical, surgery, magnetic fields, biology, histology and high temperature use
