100% brand new three-prong laboratory clamp — durable metal construction with plastic-coated tines for safe, reliable holding of small glassware and plungers. Key benefits Secure, stable hold: Three prongs provide multiple contact points to grip plungers and test tubes firmly during use. Protects equipment: Plastic-coated tines prevent scratches and surface damage to glass or plastic labware. Long-lasting performance: Solid metal construction designed for repeated laboratory use and reliable durability. Easy to install and adjust: Clamp base attaches to a desk or bench edge and tightens for a stable mounting without tools. Function and compatibility Designed to hold standard test tubes and plungers securely at a bench edge. Adjustable clamp base fits most table or bench edges for flexible placement. Plastic-coated tines are compatible with glass and plastic labware, minimizing abrasion. Practical use scenarios Routine titration or sample processing: Secure a test tube at the bench edge to free hands for pipetting or reagent addition. Dispensing or aspiration tasks: Hold a plunger steady while drawing or delivering liquids for consistent results. Setup for observation or photography: Stabilize small tubes or syringes at bench height for close inspection or imaging. What makes it stand out Simple, dependable design that combines a three-prong grip with a firm bench-mounted base. Protects delicate labware surfaces with coated tines while delivering the stability of metal construction. Suitable for laboratory benches, technician workstations, and teaching labs where secure, non-damaging holding of test tubes and plungers is required.
