Featuring heavy-wall construction annealed at 600°C, it offers exceptional thermal shock resistance and chemical durability. Equipped with vacuum-tight 19/22 standard taper joints and a self-lubricating 2mm PTFE stopcock, it ensures contamination-free, leak-proof operation. Ideal for essential oil extraction and continuous water separation, this receiver trap integrates seamlessly into reflux setups, making it an indispensable tool for advanced laboratory distillation. ## Description The dean stark distillation receiver is for easy separation of water from reaction or distillation system, can be used in essential oil extraction. With 19/22 joints, graduated with 2mm PTFE stopcock.205mm in Height and 75mm in width. Laboy glassware is made of high-quality borosilicate glass and annealed at 800 degree Celsius, can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling. Review: Underrated essential lab equipment - A dean stark trap has never been on my radar until I was steam distilling an essential oil that I discovered is mysteriously is heavier than water. I bought one for that reason, but have realized what a versatile piece of equipment it actually is. Need to do a distillation but don’t have enough room? Take one stand with two clamps and you can set up a distillation using a Dean stark and a Liebig column vertically and the footprint is barely larger than your mantle. Leave the stopcock open and use some tubing to direct your distillate where you need it to go. Need to do a fractional distillation but don’t want to continuously be watching the thermometer? Leave the stopcock closed and do your thing. Dean stark with a reflux column on it will continue to reflux if you forget about it. Just dump the stopcock occasionally and the worst you can overshoot is ~30ml so you don’t have to run the entire fraction again. While not as efficient as a vigreux column, the Dean stark does offer a bit of separation because the vertical piece is long enough for some higher boiling point fractions to condense before going over to the reflux column above. Not sure when your solvent is going to distill off? Fill the graduated column with fresh solvent and dump off 5-10ml at a time and look for biphasic separation (if immiscible) or refractive changes (if miscible). Don’t have/don’t want to clean/use a claisen adapter to keep adding your reaction mixture to the distillation/reflux? Pour it right in the top, dump the graduated section, replace your solvent and keep distilling. DISCLAIMER: I’m a total hack self-taught chemist, so please, PLEASE, consider that if you’re crazy enough to take my advice, but I would say this is one of the most used items in my lab! Review: A bargain for a Dean and Stark with great quality - Fast shipping of a good quality apparatus. Very affordable as well. Others on desertcart are in the hundreds range. ## Features - [PROFESSIONAL GRADE] - Manufactured from premium Borosilicate Glass 3.3, annealed at 600°C to eliminate residual stress. This heavy-wall construction ensures high resistance to thermal shock and chemical corrosion, ideal for rigorous laboratory use. - [AZEOTROPIC DISTILLATION] - Specifically designed for the continuous separation of water from a reaction system. The vapor rises through the side arm, condenses, and drops into the graduated trap where water separates from the solvent, driving the reaction forward. - [PRECISION GRADUATION] - Features a 5mL capacity receiver tube with clear, permanent graduations. This allows for accurate measurement and monitoring of the collected distillate volume during synthesis or essential oil extraction. - [PTFE STOPCOCK] - Equipped with a 2mm PTFE (Teflon) stopcock. Unlike glass stopcocks, PTFE is self-lubricating, chemically inert, and requires no grease, ensuring a contamination-free environment and preventing seizing. - [LEAK-PROOF JOINTS] - Designed with standard taper 19/22 inner and outer ground glass joints. Precision grinding ensures a vacuum-tight seal, compatible with standard lab glassware for secure assembly in reflux setups. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B018926CX4 | | Best Sellers Rank | #450,561 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #339 in Lab Distillation Apparatus #15,145 in Lab Instruments & Equipment | | Bottom Shape | Round | | Brand | LABOY | | Brand Name | LABOY | | Capacity | 5 Milliliters | | Customer Reviews | 5.0 out of 5 stars 11 Reviews | | Item Weight | 1 Grams | | Manufacturer | Laboy | | Material | Borosilicate Glass | | Material Type | Borosilicate Glass | | Model Number | HMD013402 | | Part Number | HMD013402 | | Specification Met | Astm | | Unit Count | 1.0 Count | ## Product Details - **Bottom Shape:** Round - **Brand:** LABOY - **Capacity:** 5 Milliliters - **Material:** Borosilicate Glass - **Specification Met:** Astm ## Images ![Glass Dean Stark Distillation Receiver Trap, 5mL Graduated, 19/22 Standard Taper Joints, 2mm PTFE Stopcock, Heavy Wall Borosilicate 3.3 for Azeotropic Distillation - Image 1](https://m.media-amazon.com/images/I/3163dN2cBUL.jpg) ![Glass Dean Stark Distillation Receiver Trap, 5mL Graduated, 19/22 Standard Taper Joints, 2mm PTFE Stopcock, Heavy Wall Borosilicate 3.3 for Azeotropic Distillation - Image 2](https://m.media-amazon.com/images/I/41-DDssf+7L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Underrated essential lab equipment *by J***R on September 9, 2023* A dean stark trap has never been on my radar until I was steam distilling an essential oil that I discovered is mysteriously is heavier than water.
