700 Series rubber drum
Unique ultra-low traction rate bore structure for high accuracy and stability. They are made of low-friction polypropylene material that meets industry standards and is silicone and chloride-free. Available in three different colors: primary colors for most conventional applications, amber blocks UV/visible light (up to 520nm) but is able to see the material inside the cylinder; Black blocks all light.

700 series pneumatic piston

Use the piston to evenly distribute pressure in order to evenly dispense materials with higher viscosity. The smooth moving piston (blue) requires lower dispensing pressure and prevents air entrain during dispensing. The snug scraping piston (white) provides a complete seal for low viscosity fluids. The loose fit straight wall piston (red) prevents wire drawing and bouncing when dispensing high viscosity materials. Made of polyethylene material.
