Syringe-type Hand-held Vacuum Pump


【Product Description】

Manually operated simplified vacuum pump substituted by a disposable syringe with an intake/exhaust valve unit and tubes.

【Overall Advantages to Users】

  • By being consisted of a disposable syringe, an intake/exhaust valve unit and tubes, even more portable and easy to use compared with commonly available handy type vacuum pumps.
  • Designed simply to be operated completely manually with no disposables such as electric power/oil and no maintenance costs. More suitable for physics experiments than chemistry ones because the intake/exhaust valve, despite their superior durability, can be swollen and deteriorated by being exposed to organic solvents.


  • Atmosphere
  • Atmospheric pressure
  • Air
  • Vacuum state
  • Propagation of sound in air and in a vacuum state




【To all users】

  • Better synergized and perform when used in combination with a vacuum jar with small volume by creating/keeping vacuum level suitable for the experiment of sound propagation in air and in a vacuum state.
  • Easy to do experiments under reduced air pressure state as well as compressed air pressure state because the intake and exhaust functions are separated.
  • Suitable for students’ experiments.
  • Intake/exhaust valve unit: Chrome-plated Brass
  • Syringe: Plastic (50ml)
  • Tubes: Outer diameter φ9mm (Inner diameter φ5mm ) x 250mm
  • Highest degree of vacuum: 4kPa
