Burette Stand
The burette stand features the following:
Materials:
Made of high-quality aluminum alloy or plastic for the clamp, and metal (such as iron or aluminum) for the stem and base, providing durability and corrosion resistance.
Functionality:
Designed to securely hold burettes during laboratory titration experiments, particularly on a titration table.
Clamp Design:
The clamp is often a “butterfly” or “double” type, allowing two burettes to be held simultaneously. Its jaws have sufficient elasticity to hold the burettes securely without obscuring the graduations.
Stability:
The heavy base and sturdy stem ensure stability during laboratory manipulations.
Use:
Easy to use for securing and adjusting the position of burettes, making it an essential accessory for science laboratories, schools, and factories.
