权利要求

2. Apparatus according to claim 1, wherein said enclosure is located within a thermostatically controlled enclosure and has walls incapable of passing actinic light.

3. Apparatus according to claim 1, comprising a differential pressure gauge having an electrical contact and connected to said enclosure, a dosing pump arranged to apply suction to said oxygen reservoir and to deliver the oxygen into said enclosure, said pressure gauge having a contact wired in an electrical circuit for feeding a driving motor for said dosing pump.

4. Apparatus according to claim 3, wherein said dosing pump is constituted by an automatic syringe driven by eccentric means, a cam being mounted on said eccentric means to act on the slide of a slide valve having three ways, the first of which communicates with said syringe, the second of which communicates with said oxygen reservoir, and the third of which communicates with said enclosure containing said sample.

5. Apparatus according to claim 3, whrein said dosing pump includes a contact, actuated by a cam during each cycle of said pump, and means for graphically recording pulses corresponding to the opeations of said contact on a record carrier which is moved at a constant speed.

6. Apparatus according to claim 5, further comprising a counter for recording said pulses corresponding to the operations of said contact.
