Charge-Coupled Device (CCD) is an analog shift register, enabling analog signals (electric charges) to be transported through successive stages (capacitors) controlled by a clock signal. Charge coupled devices can be used as a form of memory or for delaying analog, sampled signals. They are most widely used for serializing parallel analog signals, namely in arrays of photoelectric light sensors. CCDs are used in digital photography and astronomy (particularly in photometry, sensors, medical fluoroscopy, optical and UV spectroscopy and high speed techniques such as lucky imaging). Digital color cameras generally use a Bayer mask over the CCD. Each square of four pixels has one filtered red, one blue, and two green (the human eye is more sensitive to green than either red or blue). The result of this is that luminance information is collected at every pixel, but the color resolution is lower than the luminance resolution.

Cell culture bags are ideally suited to the expansion of T cells or the generation of dendritic cells from monocytes. The sterilized cell culture bags are gas-permeable and transparent for microscopy. It is a closed system, which reduces the opportunity for contamination but allows for easy manipulation, incubation, observation, storage, and disposal.

Identification. A clinical color change thermometer is a disposable device used to measure a patient's oral, rectal, or axillary (armpit) body temperature. The device records body temperature by use of heat sensitive chemicals which are sealed at the end of a plastic or metal strip. Body heat causes a stable color change in the heat sensitive chemicals.

Classification. Class I (general controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter, subject to the limitations in 880.9.

Flim processing or Photographic processing is the industrial process by which conventional photographic film is treated after photographic exposure in order to produce the desired negative or positive image. Photographic processing does three things: it transforms the latent image into a visible image that can be seen, it makes the visible image permanent, and it renders the film insensitive to light.The general process is similar whatever the make of film or paper. Before processing, the film must be removed from the camera and from its cassette, spool or holder in a light-proof room or container. In amateur processing, the film is removed from the camera and wound onto a reel in complete darkness (usually inside a darkroom (with the safelight turned off) or a lightproof bag with arm holes). The reel holds the film in a spiral shape, with space Flim processing or Photographic processing is the industrial process by which conventional photographic film is treated after photographic exposure in order to produce the desired negative or positive image. Photographic processing does three things: it transforms the latent image into a visible image that can be seen, it makes the visible image permanent, and it renders the film insensitive to light. The amateur or commercial level processing , the film is treated in chemical baths. Each of these baths is closely monitored and maintained at a specific temperature and treatment time. Developer baths are most sensitive to deviations from the standard processing conditions. The fixer makes the image permanent and light-resistant by dissolving any remaining silver halides.

Chemotherapy Containers are designed for the disposal of chemotherapy waste. Chemotherapy containers are available for home care use to ensure that contaminated products are transported safely. These containers are disposed of by medical waste disposal firms, which are not permitted to incinerate hazardous chemical (pharmaceutical) waste. It features gasketed containers for spill resistance, clear lid, which keeps contents and fill level visible for increased safety.
