Liquid Liquid Continuous Heavier than water extractor body lab glass

Description

The Custom Glass Shop and Kontes heavier than water Liquid/Liquid Extractor bodies. Auction is for one used item that came from the East Bay Municipal Water District in Oakland California. They have signs of wear and may have chips on the mouths, but are clean and fully functional.  I tried to take pictures of the two different styles I have. These are professional high quality borosilicate glass pieces that were used for water treatment in the Bay area, available at an extremely discounted price.
This item is very hard to ship without breakage.  USPS has been very rough with handling them and I will no longer use them after they destroyed about 5 of them.  Consequently I will have to add insurance and use a costlier method.
