Method for bubbling gas into a liquid at a specific rate?

[rwooduk]

If there are any experimentalists out there maybe you could help?

I need to bubble gas through a liquid at ~80 mL/min is there a specific instrument designed to do this? I'm assuming it's some sort of pump, what would it be called in a chemistry lab?

Thank you for any suggestions / help.
