Apparatus For Determining The Quality Of Water Absorbed And Given Off By Transpiring Plants, Borosil

The Apparatus for Determining the Quality of Water Absorbed and Given Off by Transpiring Plants (commonly referred to as a Potometer or Transpiration Apparatus) is a highly precise laboratory glassware setup used to measure the rate of transpiration in plant shoots. Fabricated from premium-grade borosilicate glass, this specialized apparatus allows researchers and educators to accurately quantify the volume of water taken up and released by a plant under varying environmental conditions.

The apparatus features a streamlined design consisting of a plant shoot reservoir, an integrated graduated capillary tube for monitoring water movement via an air bubble tracking system, and a leveling stopcock/reservoir for easy resetting. Its high thermal and chemical resistance ensures long-term calibration accuracy and baseline stability during sensitive botanical experiments.

Key Features

• Manufactured from high-purity borosilicate 3.3 glass for structural clarity and superior durability
  
• Precision-bore graduated capillary tube with high-contrast, durable enamel markings for effortless meniscus and bubble tracking
  
• Integrated glass stopcock or reservoir assembly for seamless baseline resetting between experimental trials
  
• Airtight ground glass joints to ensure zero system leaks, maintaining strict volumetric accuracy
  
• Heavy-duty glass wall construction optimized to minimize accidental breakage during plant setup changes
• International Standards
• Our plant physiology apparatus is manufactured to meet rigorous dimensional and technical tolerances, aligning perfectly with global educational and scientific specifications for international export:

• ISO 4788 – Laboratory Glassware – Standards for Volumetric and Capillary Dimensions
