Apparatus For The Demonstration Of Osmotic Pressure, Pfefer Complete With Borosilicate Glass Jar

The Apparatus for the Demonstration of Osmotic Pressure (Pfeffer's Type) is a classic, highly precise laboratory setup engineered to demonstrate the principles of osmosis and quantitatively measure osmotic pressure in fluid solutions. Manufactured to export-quality standards, this apparatus provides a clear visual and analytical representation of molecular transport across a semi-permeable membrane.

The complete system comprises a premium, heavy-wall borosilicate glass jar that serves as the outer solvent reservoir, a specialized inner porous pot or membrane cell assembly, and a precision-bore vertical capillary tube with high-contrast graduation markings. The use of high-grade borosilicate glass ensures flawless optical clarity, excellent chemical resistance to standard solute solutions, and the structural integrity required to withstand hydrostatic pressure differentials.

Key Features

• Outer reservoir fabricated from high-purity borosilicate 3.3 glass for superior chemical inertness and clarity
  
• Precision-graduated glass capillary tube featuring durable, easy-to-read enamel calibrations for precise meniscus tracking
  
• Airtight ground glass joint configurations and rubber-sealed compression fittings to eliminate pressure leaks
  
• Heavy-duty structural design with uniform wall thickness to resist mechanical shock during assembly and operation
  
• Supplied as a complete, turn-key kit ready for immediate integration into physics, physical chemistry, or plant physiology setups

International Standards

Our osmotic pressure demonstration apparatus is manufactured in strict compliance with globally accepted scientific manufacturing tolerances, making it highly suitable for international distribution, tender boards, and export:
