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.
- 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.
