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 .
used as a portable autoclave Biological and chemical indicators: Used to ascertain if a certain process has been completed, e.g. spores used in an autoclave are killed if autoclaving is properly done Filters: •Candle filter: used as household water filters and as filters for large particles in the laboratories
contents; usually it is not used Water bath: for flotation tests to detect presence of gas, specially for infants (lungs, intestine) as a sign of postpartum life Specimen jars/envelopes/packets: preservation of material evidence Swabs: collecting smears Metacarpal saw: video: External link; a bone saw Double-ended probe: used for probing Tongue tie
Good laboratory practice dictates that, after each measurement, the probes are rinsed with distilled water or deionized water to remove any traces of the solution being measured, blotted with a scientific wipe to absorb any remaining water, which could dilute the sample and thus alter the reading, and then immersed in a storage solution ...
A water bath is laboratory equipment made from a container filled with heated water. It is used to incubate samples in water at a constant temperature over a long period of time. Most water baths have a digital or an analogue interface to allow users to set a desired temperature, but some water baths have their temperature controlled by a ...
Michigan O probe with Williams markings (left) and Naber's probe with shades alternating every 3 mm (right). Proper use of the periodontal probe is necessary to maintain accuracy. The tip of the instrument is placed with light pressure of 10-20 grams [ 1 ] into the gingival sulcus , which is an area of potential space between a tooth and the ...
[12] [failed verification] These probes are also called resistive divider probes, since a 50 ohm transmission line presents a purely resistive load. The Z 0 name refers to the characteristic impedance of the oscilloscope and cable. The matched impedances provide better high-frequency performance than an unmatched passive probe can achieve, but ...
Drawing of a Thiele tube with red arrows showing convection current A photograph of a Thiele tube. The oil level is a little low now to compensate for expansion when heating commences. The Thiele tube, named after the German chemist Johannes Thiele, is a laboratory glassware designed to contain and heat an oil bath.
