Hi all Made enquiries to Serrata regarding the pre-mix Thymol Blue.It is not yet listed in any of the catalogues.Don't fall over in shock :w00t: :w00t: :w00t: but the price for 0.04% pure grade 500mls is $158.00 plus GST.Because it is an item that is not kept in stock it would take 4-5 weeks for del...
