The BioChamber 2000 is a modified food storage container that will allow you to insert our various gas sensors into the top of the chamber. We do not sell chambers that are larger than 2L, but you can purchase a larger container from Amazon or from other suppliers (4L / 4 Qt). Just make sure the container is a Cambro Camwear Round Food Storage Container. Make sure it is made from clear polycarbonate and is 4 Qts in size. Look for Part# RFSCW4135.

• The lid on the BioChamber 2000 should fit this 4L chamber.
• If you have the Go Direct CO2 the chamber is large enough that you can place them inside the chamber and may not need a lid with holes in it.
• Please remember that all Vernier Science Education gas sensors should not get wet.
• If you need to make holes in the lid for your sensors you can purchase grommets here.
• For best results, seal the the lid with Parafilm sealing tape as the lid is not airtight.
