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.
Test image of jelly beans from the USC-SIPI image database. A standard test image is a digital image file used across different institutions to test image processing and image compression algorithms. By using the same standard test images, different labs are able to compare results, both visually and quantitatively.
Cystoscopy has similar indications in animals, including visualisation and biopsy of mucosa, retrieval or destruction of urinary bladder stones and diagnosis of ectopic ureters. [ 9 ] [ 10 ] [ 11 ] In turtle and tortoises, cystoscopy has additional value as it permits the visualisation of internal organs due to the thin urinary bladder wall. [ 12 ]

A microplate, also known as a microtiter plate, microwell plate or multiwell, [1] is a flat plate with multiple "wells" used as small test tubes. The microplate has become a standard tool in analytical research and clinical diagnostic testing laboratories.
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.
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).
