Product Description
Removing water from a reaction as it forms drives equilibrium toward your product and gives a visible measure of progress. This Dean-Stark receiver handles both solvents heavier than water and solvents lighter than water, so one trap covers a wide range of azeotropic distillations and moisture determinations.
This listing is for Kimble catalog number 535801-0000: KONTES Dean Stark Distillation Receiver. A compact graduated trap sits well above the boiling flask, and a lower three-way stopcock serves as a sample port and lets you drain the trap without taking the apparatus apart. The 20 mL trap is graduated 0-3 mL in 0.2 mL and 3-20 mL in 0.5 mL, with a 24/40 main joint and a 10/30 thermometer joint. It is made from low-extractable 33 expansion borosilicate glass. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
Key Features
- Heavy or light solvents – Design works with solvents denser or less dense than water.
- Three-way stopcock – Lower stopcock provides a sample port and drains the trap without disassembly.
- Fine graduations – 0.2 mL divisions in the lower range allow accurate small-volume water readings.
- Elevated trap – Trap positioned well above the boiling flask for stable separation.
- Thermometer joint – Standard Taper 10/30 port for temperature monitoring.
