C1805 culture tube closures are designed to fit 25 mm diameter culture tubes (C2093, C935, C2035, C2039, C2040). As with all culture tube closures, if the cap is initially tight fitting you may need to twist while pressing it on to slide it over the top of the tube. Once autoclaved, culture tube closures typically fit much more comfortably.
