Premium ring clamp for laboratory use — 100% brand new, durable metal construction with an adjustable clamp base and plastic-coated pins. Key benefits Built to last: all-metal construction delivers reliable strength and long service life for repeated lab use. Stable, secure setup: adjustable clamp base fastens to a table edge or bench to keep assemblies steady during experiments. Protects glassware: plastic-coated pins prevent scratches and scuffs on flasks, funnels, and other apparatus. Easy to position: the clamp adjusts quickly for precise height and angle so you can align equipment without reworking the setup. Simple maintenance: corrosion-resistant metal needs minimal care and performs consistently over time. What it solves Eliminates wobble and instability in distillation, heating, and filtration setups by securing support hardware to the bench edge. Prevents damage to fragile glassware that can occur with bare metal contact thanks to protective coated pins. Saves time setting up experiments by offering a quick, adjustable support that stays firmly in place. Typical applications Distillation: hold condensers or support flasks in a distillation assembly for steady, safe operation. Heating and reflux: secure round-bottom flasks or receivers when applying heat to maintain alignment and prevent spills. Filtration and titration: position funnels or burettes for controlled transfers and clean setups.
