Rave Scientific offers a selection of fine needle probes and picks for microscopy sample preparation and microscopy probing applications. There is a choice of 5 different types of fine probing needles and two different needle holders; the fine needle probes can be quickly and easily exchanged when damaged or when another fine needle type is needed. The fine needle probes can also be used as a cost-effective solution for probing under the microscope; the slim needle holders can be mounted in micro-manipulators. The larger stainless steel probes are intended for sample gathering and sample preparation. The Micro-Tec probes are crafted from a single piece of stainless steel and are quite sturdy. The cost effective Value-Tec probes are made with a stainless steel needle probe fused in a stainless steel handle and are intended for finer probing applications.
