Piston Comparison Techcon 700 Series Dispensing Syringes

Pressure inside the dispensing syringe is evenly spread across the fluid surface by the piston that provides consistent dispensing performance. Double wiper seal pistons prevent dripping and eliminate material wastage in the dispensing syringes by wiping  the barrel wall clean, as fluid is deposited.

Using dispensing syringes without a piston inserted can result in unreliable dispensing deposits, as the supplied air pressure can become trapped inside the fluid, resulting in void pockets throughout the dispensing syringes. In addition moisture, found in the air of dispensing syringes, can affect the properties of the fluid.

Techcon Systems is pleased to demonstrate the advantage of each piston type our dispensing syringes:

700 Series Dispensing Syringes
		Low friction pistons are recommended for most general applications. They prevent air entrapment and eliminate material waste by wiping the barrel wall clean of the dispensing syringes.
		The tighter fit wiper pistons are recommended for use with dispensing syringes, such as a manual syringe gun, to prevent leakage past the double wiping edges.
		Straight wall pistons are recommended with dispensing syringes for reduced stringing and "bouncing" when dispensing high viscosity fluids.
