You Searched For: Nitrate(N) Standards

Bossheads are essential parts to complete the laboratory retort stand construction for titration, filtration, or distillation experiments. With two screw clamps, bossheads attach to the vertical rod supported by the apparatus base and simultaneously securely hold the sample. All designs are lightweight and durable for testing longevity and come in a variety of finishes. Some are designed to fit the standard rod diameter, while others have more flexibility in sizes. Rotating designs allow any angle to be achieved.
