Description
Replacement PTFE spindle, lateral is a spare spindle intended for lateral burette valve stopcocks used in volumetric laboratory work. Manufactured from PTFE, the spindle restores smooth, chemically resistant operation when the original spindle is worn or damaged. It is designed specifically for side-mounted burette valve stopcocks, ensuring correct geometry and reliable sealing during titration and other controlled dispensing tasks. Supplied as one piece with a net weight of 0,009 kg, the component is easy to stock as a maintenance part for glassware workshops and analytical laboratories. PTFE provides inherent resistance to a wide range of aqueous and organic reagents and helps prevent sticking under routine laboratory conditions. This replacement PTFE spindle from manufacturer Witeg supports continued accuracy and leak-free performance of existing burette assemblies without the need to replace the entire stopcock. It is a practical consumable for chemical, pharmaceutical, educational and quality-control environments that rely on precise volumetric glassware.

Questions about Seperate PTFE-valve plug lateral
What is this article?
Seperate PTFE-valve plug lateral is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Viscometers, inside Density & viscosity measurement, in Lab instruments.
A capillary viscometer times the flow of a liquid through a tube. A rotational viscometer twists a spindle in the liquid. Both need a stated temperature. Kinematic and dynamic viscosity are different numbers. The capillary size has to put the flow time in the range the method allows.
Density is mass divided by volume. A hydrometer floats at a depth that depends on the density of the liquid. A pycnometer is a vessel of known volume that is weighed full. Viscosity is the resistance to flow. A capillary viscometer times how long a volume takes to fall through a tube. Both measurements need a stated temperature, because liquids change density and viscosity as they warm. The units trace to the BIPM and to NIST.
