These tube-shaped borosilicate glass chambers are designed for measurements of oxygen consumption rates in resting/inactive aquatic organisms (e.g., fish or inverts), and have ports for intermittent respirometry.

The ground glass joint stopper makes for a gas and water tight seal, and can be combined with tubes with similar inner diameter (ID) but different lengths to get a range of volumes/sizes.

Mini chamber stopper with two borosilicate glass ports for flushing/mixing the chamber or for injecting sample or substances. The ground glass joint provides 100 % tight seal when the chamber is closed.

With this replacement tube, you can build a longer or shorter respirometer chamber using a glass stopper with similar inner diameter (ID).

Use this holder with up to four mini chambers ID 9-28 mm.

To hold chambers of different dimensions, we offer adapter rings that matches the outer diameter of each available chamber.

The holder can be mounted inside a water bath for thermostatic control.

These adapter rings (set of four rings) can be used to fix mini chamber (horizontal) and/or mini chamber (vertical) in our water bath for mini chambers.

This acrylic water bath (L400 x W225 x H140 mm) for one of our horizontal or vertical mini chamber holders, comes with a lid and ½" fittings for running thermostated water through it.
