If you're not concerned about plastic, you can just use the Ratio 6's server/dripper they provide for a full batch.

If you want a full pot of coffee with less plastic, I recommend buying the Ratio's glass carafe from their website and these filters: https://www.amazon.com/gp/product/B07414J9WP/

Then if you want it in an insulated server to keep it hot, get a double wall thermos or server (like this https://www.amazon.com/Stainless-Insulated-Retention-Non-Slip-Silicone/dp/B08H25DXHV/ or this https://www.amazon.com/gp/product/B01DZQT3IU) Preheat the server/thermos with hot water while you brew into the glass carafe. Then after the brew, pour the coffee into the preheated thermos.

Ratio also sells the thermos and dripper from their Ratio 8 as a separate device, which I believe also eliminates more plastic vs. the stock Ratio 6 server. https://ratiocoffee.com/collections/ratio-accessories/products/ratio-thermal-carafe-with-porcelain-dripper. The thermos just doesn't look like it's well insulated. So I opted for the glass carafe + better thermos route for full batches.
