Featuring precision graduations, a chemically inert 2mm PTFE stopcock, and vacuum-tight 19/22 taper joints, it’s engineered for efficient azeotropic distillation and seamless integration into standard lab setups. ## 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. ## 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 | #603,731 in Industrial & Scientific (See Top 100 in Industrial & Scientific) #519 in Lab Distillation Apparatus #20,547 in Lab Instruments & Equipment | | Bottom Shape | Round | | Brand Name | LABOY | | Capacity | 5 Milliliters | | Customer Reviews | 5.0 5.0 out of 5 stars (11) 5.0 out of 5 stars | | Item Weight | 1 Grams | | Manufacturer | Laboy | | 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 ![Laboy 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) ![Laboy 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 on Reviewed in the United States 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. 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! ### ⭐⭐⭐⭐⭐ A bargain for a Dean and Stark with great quality *by on Reviewed in the United States May 25, 2019* Fast shipping of a good quality apparatus. Very affordable as well. Others on amazon are in the hundreds range. ### ⭐⭐⭐⭐⭐ As described *by on Reviewed in the United States November 21, 2019* I love Laboy they're the very best. ## Frequently Bought Together - Laboy Glass Dean Stark Receiver Head Apparatus Trap Graduated 5ml with 19/22 Joints & 2mm PTFE Stopcock Lab Glassware - LAB FISH Laboratory Heating Mantle Thermostatic Heater with Magnetic Stirring Digital Temperature Control 2000ml - VEVOR New Laboratory Glassware 24/40 Chemistry Glassware 29PCS Chemistry Lab Glassware Kit 250 1000ml for Distillations Separation Purification Synthesis 24/40 29PCS --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/73500702-laboy-glass-dean-stark-distillation-receiver-trap-5ml-graduated-19](https://www.desertcart.sn/products/73500702-laboy-glass-dean-stark-distillation-receiver-trap-5ml-graduated-19) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-12*
