The Micro-Tec fine needle probes and needle probe holders offer a practical and affordable solution for probing, marking, scribing, picking, sorting and cleaning in microscopy, experimentation, research, sample preparation and assembly applications. Two type of probe holders four types of fine needle probes and two types of ultra-fine needle probes are offered to cover a wide range of applications. In addition, they are also available in combination sets.
Micro-Tec PV1 and PV5 needle probe holders
There are two types Micro-Tec needle probe holders with precision steel collets to accommodate the Micro-Tec needle probes:
Micro-Tec PV1 standard brass needle probe holder comprises a grooved brass body for improved grip and a tool steel collet for holding probes from 0.1 to 0.65mm diameter. Collet chuck is made from brass. Length is 95mm, body diameter is 5mm
Micro-Tec PV5 long and sleek stainless steel probe holder for probes from 0.1 to 0.65mm diameter. Body, collet and collet chuck are all made from stainless steel. Length is 152mm, body diameter is 4mm. Intended for use with microscopes.
Micro-Tec fine and ultra-fine needle probes
The choice of Micro-Tec fine needle probe includes:
Stainless steel fine needle probes, straight and angled
Black enameled steel fine needle probes, straight
Carbon tool steel fine needle probe, straight
Ultra-fine tungsten probes, straight and angled
1 – Micro-Tec stainless steel fine needle probes exhibit good corrosion resistance and can be used in aqueous solutions. They tend to be more flexible and are suitable for probing, sorting, cleaning and picking. These needle probes can be bend up to 90° if needed. Available stainless steel needle probes are:
Straight stainless steel sharp pointed fine needle probes with 0.25, 0.35, 0.45 and 0.55mm diameter, 35mm long
Angled stainless steel sharp pointed fine needle probes with 0.25, 0.35, 0.45 and 0.55mm diameter, 35mm long
2 – Micro-Tec black enameled fine needle probes provide a better contrast against a light background or parts. They are flexible and suitable for probing, sorting, cleaning and picking. These needle probes can be bend to a slight angle. Available black enameled needle probes are:
Straight black enameled steel sharp pointed fine needle probes with 0.25, 0.35, 0.45 and 0.55mm diameter, 35mm long
3 – Micro-Tec hardened carbon tool steel fine needle probe is more rigid and harder than stainless steel probes. They are useful for probing, marking, scribing and cleaning.
Fine pointed straight hardened carbon tool steel needle probe with 0.40mm diameter, 28mm long. Nickel plated for improved corrosion resistance.
4 – Micro-Tec ultra-fine tungsten needles probes with a 0.6µm tip radius are useful for probing and manipulating samples under a microscope. The ultra-fine tungsten probe are hard, rigid and wear resistant.
Ultra-fine straight tungsten needle probe with 0.52mm diameter and a 0.6µm tip radius, 25mm long
Ultra-fine angled tungsten needle probe with 0.52mm diameter and a 0.6µm tip radius, 25mm long
All Micro-Tec needles probes can be used with either of the Micro-Tec needle probe holders, micro-manipulators, probe holders or precision pin vises compatible with 0.25-0.55mm probe diameters.
With their small diameters, the Micro-Tec probe holders are compatible with a variety of micro manipulators.
