Jointed Erlenmeyer Flask, 250mL, 24/40

This filter flask features: heavy wall, flat bottom, and standard taper joint for fitting with a 24/40 stopper. The filter flask looks like an Erlenmeyer flask but is thicker and made to withstand vacuum.

Filter flasks are also called "side-arm flasks" and "vacuum flasks" and are used either for filtering solutions or for removing solvent under reduced pressure.
