Product Description
Running multi-step syntheses is simpler when one vessel accepts a stirrer, condenser, thermometer and addition funnel all at once. This 2 L reaction flask assembly gives chemists a heavy-walled, grease-free setup that holds vacuum reliably and cleans up quickly between batches.
This listing is for Kimble catalog number 614000-2000: KONTES 2L Unjacketed Reaction Flask Assembly. The flask and its flat flange lid are made from 33 expansion low-extractable borosilicate glass meeting USP Type I and ASTM E438 Type I, Class A. The lid provides four 24/40 standard taper necks, and walls are roughly 5 mm thick. An FKM O-ring seals the flange for grease-free vacuum work, and a PTFE valve plug is supplied with the flask. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
Key Features
- Four 24/40 necks – Lid accepts stirrers, condensers, probes and funnels simultaneously.
- Grease-free seal – FKM O-ring connection supports vacuum operation without grease.
- Heavy 5 mm walls – Robust glass resists mechanical and thermal stress.
- PTFE valve plug included – Ready for controlled draining out of the box.
- Low-extractable glass – Meets USP Type I and ASTM E438 Type I, Class A.
