A probe tip is an instrument used in scanning probe microscopes (SPMs) to scan the surface of a sample and make nano-scale images of surfaces and structures. The probe tip is mounted on the end of a cantilever and can be as sharp as a single atom .
On drop indicators, the tip of the probe usually may be interchanged with a range of shapes and sizes depending on the application. The tips typically are attached with either a #4-48 or an M2.5 screw thread. Spherical tips are often used to give point contact. Cylindrical and flat tips are also used as the need arises.
Existing nanoprobe needles or “probe tips” have a typical end-point radius ranging from 5 to 35 nm. [2] The fine tips enable access to individual contacts nodes of modern IC transistors. Navigation of the probe tips in SEM based nanoprobers are typically controlled by precision piezoelectric manipulators. Typical systems have anywhere from ...
A Luggin capillary (also Luggin probe, Luggin tip, or Luggin-Haber capillary) is a small tube that is used in electrochemistry. The capillary defines a clear sensing point for the reference electrode near the working electrode. [1] [2] This is in contrast to the poorly defined, large reference electrode.

Hose link is a 1/4-turn bayonet-mount garden hose connection, which uses an o-ring to o-ring seal. It was designed by Hoselink, Pty, Ltd., Australia, [24] and patented in 1998. [25] It is popular in Australia, with limited distribution in the UK and the US, where it is distributed by Dayco Products, Inc.

A coaxial power connector is an electrical power connector used for attaching extra-low voltage devices such as consumer electronics to external electricity. Also known as barrel connectors , concentric barrel connectors or tip connectors , these small cylindrical connectors come in an enormous variety of sizes.
The matched impedances provide better high-frequency performance than an unmatched passive probe can achieve, but at the expense of the low 500-ohm load offered by the probe tip to the DUT. Parasitic capacitance at the probe tip is very low so, for very high-frequency signals, the Z 0 probe can offer lower loading than any hi-Z probe and even ...
