1000ml jobo bottles for any size tank?

I have access to a jobo cpe2 with a lift. It only has 1000ml chemistry bottles for the immersion inserts, but I'm confused about using larger tanks... Do I need larger bottles for 1500ml or 2000ml+ tanks? I can't find any other bottles, and wouldn't they only be partially submerged?

Thanks!

Not sure if I understand you correctly, but the 1000ml bottles are for stock solution and then there are 260ml clear plastic graduates that are used to bringing the chemistry up to processing temperature immediately before use. 2000ml Jobo bottles do exist, but they wll not fit the CPE2 and I am not sure why you would want to fill a Jobo tank with 1500, 2000 or even 1000 ml.
The maximum load for a tank used on the CPE2 is 600ml of chemistry, if use more you will stress and eventually kill the motor.
But the amount of liquid necessary to cover film or prints in the drums that can be used on the CPE2 should be less than 600ml anyhow.
Some of the Jobo tanks specify minimum amounts of liquid for processing in rotational mode as well as inversion mode.
Make sure you pick the right type of number, else you will overload the tank and waste chemistry or, worse, kill the motor.

I have a CPE2. I have 1000ml bottles and 600ml for storage. 2 films in a 1500 tank (2 135 or 120 film) use 260 ml solutions for developing. I use the 270ml graduates (260ml graduated, but 270 of maximum full volume) for the working solution when developing E6. Since I only have 3 of the graduates 260ml, my c-41 chemicals are stored in the 600ml botltles, and I use them when developing, using them in the processor (warming them in it).

Try and get a copy of the operating manual.

Actually rather than try you need to get a manual. You need to go to some place like this http://www.jobo-usa.com/resources/manuals So see if you can find a place like that.

I use the 1 liter bottles for storage. I use the 600ml bottles and the graduates while processing.

The only bottles that properly work with the CPE2 are 600ml bottles, which are in stock (though not for long).
The CPE2 manual is readily available for free on the Jobo USA website.
