Product Description
Rotary evaporators and vacuum work demand flasks that can take repeated stress. These heavy wall round bottom flasks are a strong choice for rotary evaporator condensate collection and serve as direct replacements for European KS 35/20 style spherical joint flasks.
This listing is for Kimble catalog number 601050-0935: Heavy Wall Round Bottom Flask, 35/20, 3000 mL. The flasks have spherical ground joints in 35/20 or 35/25 sizes and come in capacities from 500 to 5000 mL. Thick walls add durability under vacuum and frequent handling. They are made from low-extractable 33 expansion borosilicate glass meeting USP Type I and ASTM E438 Type I, Class A. Secure joints with an appropriate pinch clamp. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
