Prior to the development of the tape dispenser, 3M's standard clear scotch tape was sold as a roll, and had to be carefully peeled from the end and cut with scissors. To make the product more useful, the scotch tape sales manager at 3M, John Borden, designed the first tape dispenser in 1932, which had a built-in cutting mechanism and would hold the cut end of the tape until its next use.
Perfluoro(2-methyl-3-pentanone) is a fluorinated ketone with the structural formula CF 3 CF 2 C(=O)CF(CF 3) 2, a fully-fluorinated analog of ethyl isopropyl ketone.It is used as an electronics coolant liquid and fire protection fluid sold commercially by 3M under brand names such as Novec 1230, Novec 649, and FK-5-1-12.
A typical paint valve system will have a "female" valve, the stem being part of the top actuator. The valve can be preassembled with the valve cup and installed on the can as one piece, prior to pressure-filling. The actuator is added later. Modern aerosol spray products have three major parts: the can, the valve and the actuator or button.
Bottled water dispensers can be top-mounted or bottom-loaded, depending on the design of the model. Bottled water dispensers typically use 11- or 22-liter (5- or 10-gallon) dispensers commonly found on top of the unit. Pressure coolers are a subcategory of water dispensers encompassing drinking water fountains and direct-piping water dispensers.
Syringe pump. A media dispenser or a culture media dispenser is a device for repeatedly delivering small fixed volumes (typically between 1 ml and 50 ml) of liquid such as a laboratory growth medium like molten agar or caustic or volatile solvents like toluene into a series of receptacles (Petri dishes, test tubes, Fernbach flasks, etc.).
XT Anesthesia Workstation, an automated dispensing cabinet used in hospital operating rooms. Automated dispensing is a pharmacy practice in which a device dispenses medications and fills prescriptions. ADCs, which can handle many different medications, are available from a number of manufacturers such as BD, ARxIUM, and Omnicell.
Microdispensing is the technique of producing liquid media dosages in volumes of less than one microlitre. The continuing miniaturization in almost all technical areas creates constant challenges for industry, development and research facilities.
The devices using this method to achieve atomization are called as airblast, air-assist, or popularly twin-fluid atomizers. In a Rotary Atomizer, the rotating cup or disc forces the liquid to come out at a very high speed through its rim. [1] [2] The Rotary, Pressure-swirl [3] or Twin-fluid Atomizers [4] are the most common methods for spray ...
