Description
Product Overview
The KimLab Amber Glass Separatory Funnel is engineered for scientists who demand reliability, precision, and durability in their liquid handling equipment. Constructed from premium amber‑tinted borosilicate glass, the funnel resists thermal shock and chemical attack, ensuring a long service life even under demanding laboratory conditions. The conical body, featuring a #24/29 upper opening, facilitates efficient phase separation while minimizing residue retention. Each unit is equipped with a PTFE (polytetrafluoroethylene) stopcork that creates a chemically inert, leak‑proof seal, preventing cross‑contamination and loss of valuable reagents. Available in a range of capacities—125 ml, 250 ml, 500 ml, and 1000 ml—this funnel accommodates diverse experimental scales, from microscale reactions to larger batch processes. The optional glass stopcork provides an alternative for users who prefer a fully glass‑based assembly, while the PTFE version offers superior resistance to aggressive solvents.
Usage
Designed for a broad spectrum of laboratory applications, the Amber Glass Separatory Funnel excels in organic synthesis, analytical chemistry, and environmental testing. Its robust construction makes it suitable for routine extractions, such as liquid‑liquid separations, acid‑base extractions, and solvent washes. The clear amber hue reduces glare while still allowing visual monitoring of phase boundaries, which is essential for precise layer removal. Researchers in academic, industrial, and quality‑control settings will find the funnel indispensable for tasks ranging from small‑scale sample preparation to pilot‑plant scale separations. The PTFE stopcork’s low friction enables smooth opening and closing, even after repeated cycles, while its inertness guarantees that no leachable substances interfere with sensitive analyses. Whether you are separating aqueous and organic layers, purifying reaction mixtures, or performing distillation pre‑treatments, this funnel delivers consistent performance.

FAQ
What types of solvents can the PTFE stopcork withstand?
The PTFE stopcork is compatible with most organic solvents, including chloroform, dichloromethane, ether, and hexane, as well as aqueous solutions. It is resistant to acids and bases, making it suitable for a wide range of chemical processes.
Can the funnel be used for high‑temperature applications?
Yes. The borosilicate glass is rated for temperatures up to 500 °C (932 °F), allowing the funnel to be heated for reflux or distillation pre‑treatments, provided the stopcork is not exposed to temperatures exceeding its rated limit (typically 260 °C).
How do I clean and maintain the funnel and stopcork?
Rinse the glass body with appropriate solvents after each use and dry with lint‑free tissue. The PTFE stopcork can be cleaned with mild detergent or solvent, then rinsed thoroughly and air‑dried. Avoid abrasive cleaning tools that could scratch the glass or damage the stopcork surface.
Is the amber glass safe for UV‑visible spectroscopy?
While the amber tint reduces UV transmission, the funnel is primarily intended for liquid handling rather than spectroscopic measurements. For UV‑visible applications, a clear glass or quartz funnel is recommended.
Do you offer custom sizes or branding options?
KimLab can accommodate special size requests and private labeling for bulk orders. Please contact our sales team with your specifications to discuss feasibility and pricing.
