Fluid tanks, what do you have?

A while ago I purchased a pair of rizoma "next" fluid tanks . Nice units and I was assured they could be run with either brake fluid or mineral oil . Turns out that was a load of shite, within a week or so the membrane on the clutch side was knackered. Took it off and put the oem unit back on the clutch. I have seen small alloy looking things that look nice . Anyone with first hand experience able to recommend some fluid tanks that will work with both dot 3/4 AND mineral oil. Links or pics would be nifty . Thanks for any input.

Used shell synthetic fork oil as "recommended" by the stealer. Guess I have been given another bum steer.

Thanks for the info. Yes they are more of a dirt bike dealer (even though they sell super dukes) when it comes to lc8 motors they don't seem to know their azz from their elbow. Haven't been back there for some time. Charged me 200 bucks for the akra map when I first got the bike. Had an issue with a faulty thermostat not giving correct temp readings, they basically told me I would have to live with it. Got it fixed elsewhere no problem.
Charge like wounded bulls, know fook all about a lot of the products they sell ,can't fix things if you have an issue and now I find out they give customers BS information . I wont name them but they are in the western suburbs of Melbourne. Disappointing really.....

Can I assume then that any fluid tank capable of holding brake fluid will safely store magura blood?
At least the members of this forum can give accurate (free) advice
thanks again for clarifying

Yeah, Magura blood is mineral oil so it is pretty harmless stuff. You can run your Superduke clutch on Johnson's baby oil. I did on my 05 when the slave cylinder was starting to leak. It was a lot cheaper than Magura blood.

I dont know if that means you could put Magura blood on a baby's arse to prevent nappy rash though.
