Socketed vs. Without-Joint Kjeldahl Flasks
This Kjeldahl Flask carries a ground socket (19/26 or 24/29 depending on capacity), letting it connect directly to a Kjeldahl distillation apparatus or condenser after digestion — unlike the Kjeldahl Flask without Joint, which is used purely for the digestion step. The long neck and borosilicate build remain the same across both versions, containing splashing during acid digestion and resisting the thermal shock of sustained heating.
