Bulk Reagent Dispenser
A bulk reagent dispenser (BRD) is a type of Commercial off-the-shelf, commercially available laboratory equipment that dispenses liquid reagents in an automated fashion into microplates, multiwell plates, or microplate-like reservoirs, and specifically have the ability to transfer liquid from a "bulk" (i.e. >1L) source reservoir, but still dispense a programmable but relatively small volume of liquid, i.e. 10-500 μL. They are often used in drug discovery or pharmaceutical laboratories. They are distinguished from semi-automated or manual (hand-operated) equipment like pipettes, as well as from automated laboratory equipment that dispenses from relatively small source reservoirs (~10-500 μL) such as Acoustic droplet ejection, acoustic liquid handlers or liquid handling robots. History The first bulk reagent dispensers were the Titertek Autodrop and Dynatech Dynadrop MR that were first commercialized in the early 1980s & were used in immunology applications, such as diagnostic expe ...

Cartesian Coordinate Robot
A Cartesian coordinate robot (also called linear robot) is an industrial robot whose three principal axes of control are linear (i.e. they move in a straight line rather than rotate) and are at right angles to each other. The three sliding joints correspond to moving the wrist up-down, in-out, back-forth. Among other advantages, this mechanical arrangement simplifies the robot control arm solution. It has high reliability and precision when operating in three-dimensional space. As a robot coordinate system, it is also effective for horizontal travel and for stacking bins. Configurations Robots have mechanisms consisting of rigid links connected together by joints with either linear (prismatic ''P'') or rotary (revolute ''R'') motion, or combinations of the two. Active prismatic ''P'' and active revolute ''R'' joints are driven by motors under programmable control to manipulate objects to perform complex automated tasks. The linear motion of active prismatic ''P'' joints ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manifold (fluid Mechanics)
A manifold is a wider and/or larger pipe or channel, into which smaller pipes or channels lead, or a pipe fitting or similar device that connects multiple inputs or outputs for fluids. Manifolds Engineering Types of manifolds in engineering include: ; Exhaust manifold :An engine part that collects the exhaust gases from multiple cylinders into one pipe. Also known as headers. ; Hydraulic manifold :A component used to regulate fluid flow in a hydraulic system, thus controlling the transfer of power between actuators and pumps ;Inlet manifold (or "intake manifold") :An engine part that supplies the air or fuel/air mixture to the cylinders ; Scuba manifold :In a scuba set, connects two or more diving cylinders ; Vacuum gas manifold :An apparatus used in chemistry to manipulate gases Also, many dredge pipe pieces.

Check Valve
A check valve, non-return valve, reflux valve, retention valve, foot valve, or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. Check valves are often part of common household items. Although they are available in a wide range of sizes and costs, check valves generally are very small, simple, and inexpensive. Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. The bodies (external shells) of most check valves are made of plastic or metal. An important concept in check valves is the cracking pressure which is the minimum differential upstream pressure between inlet and outlet at which the valve will operate ...

Syringe
A syringe is a simple reciprocating pump consisting of a plunger (though in modern syringes, it is actually a piston) that fits tightly within a cylindrical tube called a barrel. The plunger can be linearly pulled and pushed along the inside of the tube, allowing the syringe to take in and expel liquid or gas through a discharge orifice at the front (open) end of the tube. The open end of the syringe may be fitted with a hypodermic needle, a nozzle or tubing to direct the flow into and out of the barrel. Syringes are frequently used in clinical medicine to administer injections, infuse intravenous therapy into the bloodstream, apply compounds such as glue or lubricant, and draw/measure liquids. There are also prefilled syringes (disposable syringes marketed with liquid inside). The word "syringe" is derived from the Greek σῦριγξ ('' syrinx'', meaning "Pan flute", "tube"). Medical syringes Medical syringes include disposable and safety syringes, injectio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syringe Pump
A syringe driver, also known as a syringe pump, is a small infusion pump, used to gradually administer small amounts of fluid (with or without medication) to a patient or for use in chemical and biomedical research. Some syringe drivers can both infuse and withdraw solutions. Uses Syringe drivers can be used for electrospinning, electrospraying, microdialysis, microfluidics, dispensing/dilution, tissue perfusion, and fluid circulation. Intravenous therapy Syringe drivers are useful for delivering intravenous (IV) therapies over several minutes. They infuse solutions at a constant rate. In the case of a medication which should be slowly pushed in over the course of several minutes, this device saves staff time and reduces medical errors. It is useful for patients who cannot take medicines orally (such as those with difficulty swallowing), and for medications too harmful to be taken orally. Palliative care Syringe drivers are particularly useful in palliative care, to c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coefficient Of Variation
In probability theory and statistics, the coefficient of variation (CV), also known as normalized root-mean-square deviation (NRMSD), percent RMS, and relative standard deviation (RSD), is a standardized measure of dispersion of a probability distribution or frequency distribution. It is defined as the ratio of the standard deviation \sigma to the mean \mu (or its absolute value, , and often expressed as a percentage ("%RSD"). The CV or RSD is widely used in analytical chemistry to express the precision and repeatability of an assay. It is also commonly used in fields such as engineering or physics when doing quality assurance studies and ANOVA gauge R&R, by economists and investors in economic models, in epidemiology, and in psychology/neuroscience. Definition The coefficient of variation (CV) is defined as the ratio of the standard deviation \sigma to the mean \mu, CV = \frac. It shows the extent of variability in relation to the mean of the population. The coefficien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerosolization
Aerosolization is the process or act of converting some physical substance into the form of particles small and light enough to be carried on the air i.e. into an aerosol. Aerosolization refers to a process of intentionally oxidatively converting and suspending particles or a composition in a moving stream of air for the purpose of delivering the oxidized particles or composition to a particular location. Aerosolization is also an important concept of air pollution whereby particulate matter is formed and evaded into the atmosphere. Gas-phase substances reach the atmosphere by volatilization, whereas solid and liquid-phase particles can reach the atmosphere by aerosolization. This is a mechanism by which semivolatile organic compounds (SVOCs) like halogenated and organphosphate pesticides become air pollutants . The term is often used in medicine to refer specifically to the production of airborne particles (e.g. tiny liquid droplets) containing infectious virus or bacteria. The i ...

Peristaltic Pump
A peristaltic pump, also commonly known as a roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained in a flexible tube fitted inside a circular pump casing. Most peristaltic pumps work through rotary motion, though linear peristaltic pumps have also been made. The rotor has a number of "wipers" or "rollers" attached to its external circumference, which compress the flexible tube as they rotate by. The part of the tube under compression is closed, forcing the fluid to move through the tube. Additionally, as the tube opens to its natural state after the rollers pass, more fluid is drawn into the tube. This process is called peristalsis and is used in many biological systems such as the gastrointestinal tract. Typically, there will be two or more rollers compressing the tube, trapping a body of fluid between them. The body of fluid is transported through the tube, toward the pump outlet. Peristaltic pumps may run continuousl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
