Hassan Hammadi

yes, you can use silicone oil.

Shikha Jindal

Thankyou all but can I use vegetable oil or mineral oil?

Can you precisely tell me which silicone-based antifoam and of which brand?

Sandeep Rellegadla

Yes, silicone oil is a better choice.

Try out this particular product for better results:

Do not use vegetable oil as the cells could use it as carbon source

Thankyou all...so out of silicone oil and antifoam A which is better?
