Techcon 700 Series 5cc Wiper Piston, White (1,000 Pack)

Description

The Techcon 700 Series 5cc white wiper piston fits a matching syringe barrel and moves material toward the dispensing tip as air pressure or a manual plunger advances it. This 1,000-piece pack is sized for production lines using repeatable disposable fluid paths. The white color identifies the piston during setup, while the wiper profile supports a clean, controlled stroke inside the barrel.

Where the Syringe Barrel Piston Fits

This piston is part of Techcon’s disposable 700 Series fluid path. It pairs with a 5cc barrel, a compatible receiver head or manual plunger, and the dispensing tip selected for the application. Common uses include applying adhesives, sealants, coatings, inks, pastes, and other assembly fluids in electronics, general manufacturing, transportation, medical-device production, and laboratory work. A disposable piston and barrel combination helps isolate material from reusable controller hardware and simplifies changeover when a cell switches fluids, colors, or batches.

How the Syringe Barrel Profile Works

The white wiper profile is intended to sweep the barrel wall as it moves, helping reduce material left behind after a dispensing cycle. That behavior is useful when the fluid cost, batch traceability, or cleanup burden makes residual product important. It also gives operators a visible, color-coded way to separate the wiper style from other piston profiles before loading the station.

Loading and Process Control

Confirm the barrel size before opening the piston pack because a 5cc piston should only be used with the corresponding 700 Series barrel. Fill the barrel using a method that limits trapped air, then insert the piston squarely so its edge enters the bore evenly. A tilted piston can trap a large air pocket or bind during the first stroke. Purge the filled assembly into a waste container until material flow is continuous, then verify shot weight or bead size before releasing the process for production.

Pressure, tip geometry, material viscosity, fill level, and temperature all influence dispense rate. Establish controller settings with the actual fluid and hardware combination, and record the approved setup for repeat jobs. Inspect the barrel, piston, and receiver-head seal when output changes unexpectedly. Replace disposable parts that show contamination, distortion, or damage instead of increasing pressure to force an inconsistent shot.

For repeatable results, qualify the filled assembly as a complete system. Document the barrel lot, piston style, tip, pressure, time setting, and fluid temperature. This makes troubleshooting faster and helps operators replace consumables without changing a proven process window.

Syringe Barrel Piston Specifications

Use the high-volume pack when piston consumption matches the station’s barrel usage and changeover schedule. Keep unopened pistons in clean storage near the approved barrels so dust and shop debris do not reach the sealing edge. For compatible barrels, receiver heads, plungers, and tips, browse Chemical Concepts dispensers, mixers, and nozzles.
