serpent Spine Reasearch quest

[snakebane]

I just reached level 16 on an alt enchanter and went to do the serpent spine reasearch quest. Every Cointainer I've tried has given me the you can not combine these items in this container type anybody know which one I should be using?
Thanks

It should use a Spell Research Kit

I did the quest on my alt, and almost positive thats the one i used.
