H‑Type Potometer Apparatus – KS3+ Transpiration Investigation Equipment

This high‑quality H‑Type Potometer Apparatus is specifically designed for KS3 and above, offering a clear and reliable method for investigating plant water uptake and transpiration rates. Ideal for individual student use, this potometer provides an accessible and accurate way to explore key biological processes during practical lessons.

The cut shoot is easily attached to the side arm using flexible tubing, ensuring a secure and airtight fit. The wider glass tube acts as a reservoir for water, helping maintain steady pressure and clear movement within the system. Measurement is made through the capillary tube (1mm bore), which enables students to observe water uptake with precision. All components are manufactured to robust, classroom‑ready specifications.

Ideal for School Science Lessons

This H‑Type Potometer is perfect for practical biology lessons across KS3, GCSE, and A‑Level, allowing students to observe and measure how environmental factors affect transpiration. It supports hands‑on investigation and helps build essential skills in data collection and scientific observation.

• Investigating the rate of transpiration in plant shoots
• Exploring how factors such as light, temperature, humidity, and wind influence water uptake
• Demonstrating water movement through the xylem
• Supporting required practicals for GCSE and A‑Level Biology
• Developing students’ understanding of plant transport systems

Easy to use, durable, and ideal for independent investigation, this H‑Type Potometer is an excellent resource for helping students visualise and measure the movement of water in plants during hands‑on science lessons.
