Reaction Vessel Lid with 4 Ground Joints – DN 60–200 – Borosilicate glass 3.3

Reaction vessel lids with 4 ground joints are professional components for complex laboratory setups in preparative chemistry and synthesis technology. The lids enable simultaneous operation of multiple peripheral devices through their four standard ground joint connections and offer maximum flexibility in process control.

The lids feature a straight reaction vessel flange and a total of four precisely ground connections: one central middle neck, two side necks at an angle of approx. 15° to the middle neck (angled), and one additional side neck in a straight design. This configuration allows parallel connection of stirrer shaft, dropping funnel, thermometer, reflux condenser, inert gas supply, or other laboratory components without steric hindrance.

All lids are made of high-quality borosilicate glass 3.3 according to DIN ISO 3585 and offer excellent chemical resistance and thermal shock resistance. The flange connection ensures secure and reproducible mounting on the corresponding reaction vessels.

Technical Features:

• Material: Borosilicate glass 3.3 according to DIN ISO 3585
