Large Volume Syringe

Hi, I am trying to collect air samples using a large volume air cylinder that I will mount a sensor inside of.

Kind of thing that I am looking for:

But that costs $1000+

Similar is this oil/fuel extractor for automotive use:

Also have found some enema syringes that might work but would probably be of questionable quality...

Does anyone know of anything else that could work in this regard?

I need a large diameter in order to mount a sensor inside it, and hopefully not to expensive. Ive looked at medical equipment and ventilator type stuff as I have a memory of seeing a large looking syringe type thing for air in a hospital once but probably not easy to get right now. 1-2L volume required.

Thanks for your help
