Baluue 10pcs Flow Control Tube Clamps - Adjustable Hose Clips For Lab Tubing, Silver

Need to control the flow in your lab tubing? These little metal clamps are perfect for the job. You get 10 of them in a pack. They’re made from galvanized iron, so they’re sturdy and resist rust. The design is simple but clever – you slide your tubing into the clamp and then tighten the screw to pinch it, stopping or slowing the flow. The screw swivels, making it easy to adjust even with one hand. They have little bracket feet on the bottom so they sit flat on a bench without rolling around. Each clamp is about 4 cm long. Great for any lab, hobbyist, or science fair project where you need precise control over liquids or gases in clear tubing. A basic, super useful tool to have on hand.
