Product Description
Steady, efficient reflux depends on a condenser with enough cooling surface to return vapor to the flask. The bulb-style inner tube of this Allihn design increases contact area so vapors condense reliably during long heating runs. It is a staple condenser for teaching and research labs alike.
This listing is for Kimble catalog number 431000-2420: KONTES Allihn Condenser, 370 mm. Made from low-extractable borosilicate glass 3.3, it has a standard taper drip joint at the bottom and an outer joint at the top. Water connections fit 3/8 in. ID tubing. Versions are offered with 24/40 or 29/42 joints and jacket lengths of 200 to 400 mm. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
Key Features
- Bulbed inner tube – Extra surface area improves condensation during reflux.
- Full length joints – Standard taper drip joint below and outer joint above.
- Choice of jacket length – 200, 300 or 400 mm to match cooling needs.
