Bulk syringes to expand your TeacherGeek collection

TeacherGeek Project Cylinders are the best solution for school and maker hydraulic/pneumatic projects. They come in two sizes: 4.5ml and 14ml.

What make them so great?

Holes, pins and a flange for mounting to your projects
Screws to keep the plunger and tubing from coming out (keeping the water in your project)
Volume and distance graduations on the piston
Extra-long travel (the piston moves much further 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.

Connect cylinders together using 1/8in vinyl tubing.
