English: Illustration of a micrometer caliper. The micrometer is showing a measurement of 7.145 mm ± 0.005 mm. Legend: Anvil: part that the spindle moves toward, and that the sample rests against; Spindle: moved by the thimble towards the anvil; Ratchet stop: limits applied pressure by slipping at a calibrated torque
Tube micrometers have a cylindrical anvil positioned perpendicularly to a spindle and is used to measure the thickness of tubes. Micrometer stops are micrometer heads that are mounted on the table of a manual milling machine, bedways of a lathe, or other machine tool, in place of simple stops. They help the operator to position the table or ...
An exploded-view drawing is a diagram, picture, schematic or technical drawing of an object, that shows the relationship or order of assembly of various parts. [1]It shows the components of an object slightly separated by distance, or suspended in surrounding space in the case of a three-dimensional exploded diagram.
Outside large jaws: used to measure external diameter of an object (like a hollow cylinder) or width of an object (like a rod), diameter of an object (like a sphere). Inside small jaws : used to measure the internal diameter of an object (like a hollow cylinder or pipe).
Glass chart. A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.
Micrometer can mean: Micrometer (device), used for accurate measurements by means of a calibrated screw; Micrometre, a millionth of a metre
Diagram of a simple microscope. There are two basic types of optical microscopes: simple microscopes and compound microscopes. A simple microscope uses the optical power of a single lens or group of lenses for magnification. A compound microscope uses a system of lenses (one set enlarging the image produced by another) to achieve a much higher ...
These pipettes commonly have a label with their volume range like "10–100 μL". These limits are indeed the limits as overwinding these limits would result in damage of the pipetting system. The fixed volume pipette cannot be changed. As there are less moving parts, the mechanism is less complex, resulting in more accurate volume measurement.
