The syringe dispenser is a medical device used to dispense precise amounts of fluids in various settings, including laboratory experiments and dental procedures. It can be manual or automated, and there are different types for single or dual syringes. The dispenser can be fitted with different tips for precise placement of fluids.
A medical device called a syringe dispenser is used to dispense precise amounts of low- or high-viscosity fluids in a variety of settings. It can be used for laboratory experiments or diagnostic tests, such as tissue typing. The syringe dispenser can be operated manually or automated via a connection to a laptop computer. Most are portable and are preset to repeatedly release the same volume of liquid.
Single-syringe manual hand dispensers dispense a predetermined amount of fluid from a disposable syringe barrel. The small, rectangular device contains a syringe barrel attached to a conical tip. It is operated by either thumb pressure or a lever, and the amount of pressure required to dispense the liquid can be adjusted to suit the operator’s individual preference. Prepackaged syringes prevent the operator from coming into contact with the fluid contained within the syringe barrel.
An automatic single-syringe dispenser is used to place fixed amounts of fluid on a lab plate, test tube, or small vial. Single dispensers have a replaceable syringe drive and a separate valve positioner to force fluid out of the syringe. The syringe barrel used in the dispenser is usually disposable, but some are reusable after autoclaving.
Dual Syringe Dispensers are used when two different liquids need to be dispensed simultaneously for a specific chemical reaction. A dual actuation for the syringes and dual valve positioners deliver the exact volume of liquid needed each time the device is used. Most of these dual syringe vending machines come with a safety lock to prevent accidental release of the fluid material.
Dentists make regular use of the syringe dispenser. Some dental amalgam materials are dispensed through a dual-syringe manual dispenser, preventing the substances from mixing with each other prior to application to the cavity site. The syringe dispenser can be fitted with tapered Teflon® or plastic tips to facilitate placement of the amalgam into the cavity.
An automatic repetitive syringe dispenser is needed when up to eight liquids need to be placed repeatedly on tissue culture plates. Rows of syringes are packaged as a single unit and inserted into the dispenser before each use. Syringe barrels can be quickly removed for various applications. Tapered tips ensure precise placement of fluid. Furthermore, the volume of liquid dispensed from each syringe can be quickly adapted to the specifics of the experiment or diagnostic test.
