Polylab is a Top rated, Best Manufacturer & Supplier of laboratory tubing control accessories, offering precision-designed Pinch Clip used for regulating, stopping, or controlling the flow of liquids and gases in flexible tubing systems. These clips are widely used in chemical laboratories, pharmaceutical environments, research facilities, and industrial fluid handling setups where quick and reliable flow control is required without disconnecting the tubing.
The Pinch Clip from Polylab is manufactured using high-quality, corrosion-resistant engineering plastic that ensures long-lasting durability and consistent performance. Its sturdy structure is designed to withstand repeated clamping pressure without losing elasticity or grip strength, making it suitable for continuous laboratory usage in demanding conditions.
Designed with an easy-to-operate sliding mechanism, the pinch clip allows instant opening and closing of tube flow with minimal effort. Its smooth internal contact surface ensures that tubing remains undamaged while providing secure compression control, making it highly efficient for precise experimental and fluid handling applications.

The ratchet mechanism uses interlocking teeth that engage when the clip is closed, holding it securely in the closed position. To open, you squeeze the release tabs to disengage the ratchet, allowing the clip to spring open. This design provides positive ON and OFF positions that stay securely in place until deliberately changed, preventing accidental flow changes.
These pinch clips are designed for tubing with outer diameter (O.D.) ranging from 5 mm to 9.5 mm. This covers most common laboratory tubing sizes, including standard silicone, Tygon, PVC, and other flexible tubing used in laboratory applications. For best results, ensure your tubing falls within this O.D. range.
Yes, these pinch clips are manufactured from polypropylene and are fully autoclavable at standard sterilization temperatures (121°C). This makes them suitable for sterile applications in microbiology, cell culture, and pharmaceutical settings. They can be autoclaved repeatedly without degradation.
When used correctly, these pinch clips are designed to provide secure occlusion without damaging tubing. The clamping surfaces are smooth and contoured to distribute pressure evenly. However, leaving the clip in the closed position on the same section of tubing for extended periods may cause some compression set in the tubing. For long-term clamping, occasionally rotating the tubing position or using tubing specifically designed for repeated clamping is recommended.
These pinch clips are designed specifically for ON/OFF control, with ratchet positions that are either fully open or fully closed. They are not designed for partial flow regulation (throttling). For applications requiring variable flow control, consider using a screw-type flow regulator or pinch valve with adjustable positions.
Polypropylene offers excellent chemical resistance to aqueous solutions, dilute acids, dilute bases, alcohols, and many organic solvents including acetone, ethanol, and methanol. However, it may not be suitable for strong oxidizing agents, concentrated acids, chlorinated solvents (like chloroform or dichloromethane), or aromatic hydrocarbons (like toluene or xylene). Always consult chemical compatibility charts for specific applications.
These pinch clips (Code 46201) are supplied in convenient packs of 12 pieces. This economical pack size ensures laboratories have adequate supplies for multiple setups and applications.
Yes, these pinch clips are manufactured from polypropylene material conforming to US FDA 21CFR standards, making them suitable for pharmaceutical and food contact applications. This compliance ensures they meet strict safety requirements for use in regulated environments.
Yes, these clips work excellently with silicone tubing commonly used in peristaltic pumps. The 5-9.5mm O.D. range covers most standard pump tubing sizes. They can be used to provide additional ON/OFF control points before or after the pump, or to isolate sections of tubing when changing pump tubing.
