High-quality 1000mL borosilicate round-bottom boiling flask with 24/40 taper joint, ideal for distillation and chemical reactions.
The TLG 1000mL Round-Bottom Boiling Flask is fabricated from heat-resistant borosilicate glass, providing excellent durability and thermal shock resistance vital for laboratory heating applications. Featuring a single 24/40 standard taper outer joint, this flask enables secure connectivity with standard laboratory apparatus such as condensers and adapters, critical in setups for distillation, reflux, and a range of organic and inorganic chemical reactions.
Key technical features:
This flask is widely used in biotechnology research, notably in gene editing workflows, molecular cloning, and bioprocess engineering, where precise temperature control and reliable reaction vessels are indispensable. The robust borosilicate material withstands repeated sterilization and cleaning cycles, making it an essential tool for advanced laboratories focusing on synthetic biology, clinical diagnostics, and chemical synthesis.
*Note: Price includes one flask only; cork ring shown in images is not included.*
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
