Pressure Reaction Vessels

Lab-Crest® Glass Pressure Reaction Vessels Offer Outstanding Value in Research & Industrial Labs

Visual observation of a pressurized system is one of the major advantages of Lab-Crest® glass pressure reaction vessels (also known as Fischer-Porter bottles). Chemically inert borosilicate glass construction allows you to accurately and safely observe:

  • Solubility of gases in liquids at increased pressures.
  • Chemical behavior of liquids and gases subjected to temperature and pressure changes.
  • Effect of liquids on metals.
  • Purity of propellant batches.
  • Spray and pressure characteristics.

Typical Applications Include:

  • Hydrogenation
  • Polymerization
  • Catalysis
  • Isomerization
