Test cards typically contain a set of patterns to enable television cameras and receivers to be adjusted to show the picture correctly (see SMPTE color bars).Most modern test cards include a set of calibrated color bars which will produce a characteristic pattern of "dot landings" on a vectorscope, allowing chroma and tint to be precisely adjusted between generations of videotape or network feeds.
A boiling tube is a large test tube intended specifically for boiling liquids. A test tube filled with water and upturned into a water-filled beaker is often used to capture gases, e.g. in electrolysis demonstrations. A test tube with a stopper is often used for temporary storage of chemical or biological samples.
The widely used Indian Head test pattern was generated by a monoscope. A monoscope was a special form of video camera tube which displayed a single still video image. The image was built into the tube, hence the name. The tube resembled a small cathode-ray tube (CRT).
Test tube: Folin-Wu tube: Glass slide mycole and cover slips: in microscopy, serology, etc. as the solid backing on which test samples are Petri dish: used for preparation of culture media and the culture of organisms they are in Glass beaker: reagent storage Glass flask: gastric acid, or other fluid titration: Pasteur pipette
Although a corner notch (aka chamfer) is shown at the A1 (top-left) corner in the ANSI SLAS drawings, and many microplates do implement this A1 corner notch, in actuality the "quantity and location of chamfers(s) is optional", [14] [15] so in practice the presence or absence of corner notches at additional corners (i.e. the bottom-left) is a ...
The sample is placed in a cuvette and the cuvette is placed in a spectrophotometer for testing. The cuvette can be made of any material that is transparent in the range of wavelengths used in the test. The smallest cuvettes can hold 70 microliters, while the largest can hold 2.5 milliliters or more.
