4.5ml Cylinder - Hydraulic or Pneumatic

TeacherGeek plastic, project 4.5 mL cylinders are specially designed for STEM | STEAM | DIY | Maker Space activities. Durable, consistent and so easy to use, they are simply the best solution for classroom hydraulic + pneumatic powered activities. Integral to engineering hydraulic arms, hydroponic gardens or exploring educational objectives such as Pascal's Law and fluid power. 

Connects to 1/8in vinyl tubing and 14ml project cylinders. Promote innovation, green engineering and empowered inventors - it's all possible with TeacherGeek!  

They include:

• Piston holes, pins and a flange for easy mounting to your projects
• Equipped with cylinder screws to keep the plunger and tubing from slipping, these components are water-tight, withstanding re-use across several projects
• Volume and distance graduations on the piston
• Extra-long travel (the piston moves much farther than on a syringe)

TeacherGeek Cylinders are not syringes. Their tip/port will not accept needles. This means that they are not regulated as a medical device (like syringes), and can be used in public school classrooms without issue.
