You are offerding for these 2 pieces of vintage laboratory glassware, from approx. 1950's. As can be seen these are very unusual in shape and I do not know the purpose for which they were intended. However, I am sure they would make an interesting curio for someone, or if you know what they were intended for they could still be used. They are approx. 5 1/2" long and base dia. is approx. one inch and they have 2 outlets but are not sealed at the top or the bottom. If you have any questions please do not hesitate to contact me. Please see pictures for condition as these form part of the listing. Thanks for looking and happy offerding.
