The BioChamber 2000 is a 2000 mL plastic chamber that can be used with a CO2 Gas Sensor and an O2 Gas Sensor to monitor gaseous carbon dioxide and oxygen levels simultaneously in a closed system. The BioChamber 2000 is particularly useful when monitoring respiration and photosynthesis. The large side opening provides easy access to insert, adjust, or remove the sample.The BioChamber 2000 has two sensor ports on adjacent sides. Placing one of these ports on top, as shown, allows the O2 Gas Sensor to be in its proper vertical orientation. The CO2 Gas Sensor can then be placed in the other port on the side. Note that the two sensor ports are not equally spaced. One port is centered on its side of the chamber while the other is off-center. This was done intentionally to provide two options for your sensor orientation.If you choose not to use both ports, a size 6 rubber stopper fits snugly in the grommet. Note: While the stopper fits well, it is not guaranteed to be a water tight seal.

After working hard to make our dynamics carts very low friction, we’ve added some friction back. Now you and your students can study friction in a controlled way. Add a Friction Pad DTS to your Vernier Standard Cart, Plunger Cart, or Motion Encoder Cart, and watch the carts move under very consistent friction force. Setting the friction amount is as simple as turning a knob. Friction Pad DTS is not compatible with older metal dynamics carts.

These low-friction carts are designed to study motion and collisions on the Vernier Dynamics Track. The Plunger Cart has a spring-loaded plunger for collisions, including superelastic collisions. A top tray has inserts for attaching the Dual-Range Force Sensor, Low-g Accelerometer, and Wireless Dynamics Sensor System. Removable inserts allow rapid configuration of magnets or hook-and-pile tabs for collision study. Vernier carts are also compatible with other common carts and tracks.
