Buying advice

When choosing a Luer stopcock consider material compatibility, pressure rating, dead-volume, and budget. Stainless steel offers durability and chemical resistance, while brass is cheaper but less resistant to aggressive solvents. For high-pressure or precision work select models with ceramic seats or high pressure ratings. Disposable plastic stopcocks are convenient for sterile or single-use setups.
