Piston sampler

from Wikipedia, the free encyclopedia
Piston sampler disassembled into two components, sleeve (top) and piston (middle) and ready-to-use (bottom).
Piston sampler (schematic representation).

A gas syringe is a laboratory device used in chemistry for handling gases and has replaced the gas burette in many areas . Its areas of application are:

  • Determination of the volume of a gas produced during a chemical process.
  • Carrying out an experiment with a defined volume of a gas.

The syringe is similar to a glass syringe . Its volume is usually 100 ml. The piston rests on a large area of ​​the sleeve and is ground in such a way that it is both smooth-running and gas-tight.
