Byrettitelineitä

Byrettitelineitä are laboratory apparatuses used to hold burettes securely in place during titration experiments. A burette, a long, graduated glass tube with a stopcock at the bottom, is essential for precisely delivering variable amounts of a liquid. Titration involves carefully adding a titrant (a solution of known concentration) from a burette to a solution containing an analyte (a substance being analyzed) until a chemical reaction is complete, typically indicated by a color change. Without a stable support, the burette could tip over, leading to spills, inaccurate measurements, and potential hazards.

Byrettitelineitä are commonly made of metal, often with a base and a clamp or multiple clamps. The base provides stability, preventing the entire setup from toppling. The clamp is designed to grip the burette firmly but without damaging the glass. Some racks can hold one burette, while others are designed to accommodate multiple burettes simultaneously, allowing for parallel titrations or comparative experiments. The height of the clamp on the stand can usually be adjusted to accommodate burettes of different lengths and to position the stopcock at a convenient height for manipulation. These simple yet crucial pieces of equipment are fundamental to achieving reliable and reproducible results in analytical chemistry.
