Product Overview

The EISCO 15ml Evaporating Basin is engineered for precision and durability, featuring a flat bottom that provides a stable platform for even heat distribution during solvent evaporation. Constructed from high‑quality Borosilicate 3.3 glass, the basin resists thermal shock and chemical corrosion, allowing it to be placed directly over a flame or used in high‑temperature ovens without risk of breakage. Its compact 15 ml capacity, measured at 1 inch tall with a base diameter of 0.9 inch and a top diameter of 2 inch, makes it an ideal choice for laboratories where space is at a premium, while still offering enough volume for routine analytical procedures. The integrated spout ensures smooth, controlled pouring of residual liquids, reducing waste and improving workflow efficiency. The basin’s transparent glass construction also allows users to monitor reaction progress visually, eliminating the need for additional observation tools. Its simple geometry facilitates easy cleaning, either by hand or in an autoclave, ensuring that cross‑contamination is minimized between experiments.

The flat bottom design of the basin is not merely aesthetic; it serves a functional purpose by allowing the vessel to sit evenly on heating plates, magnetic stirrers, or sand baths, thereby preventing wobble and ensuring uniform temperature exposure. This stability is especially valuable when performing delicate evaporations that require precise temperature control to avoid decomposition of sensitive compounds. The spout, positioned at the rim, is engineered with a gentle curvature that guides liquid flow into receiving containers without splashing, which is critical when handling volatile or hazardous solvents. Additionally, the spout’s dimensions are calibrated to accommodate standard laboratory glassware such as beakers and flasks, making the transfer process seamless and reducing the likelihood of accidental spills. Because the basin is made from Borosilicate glass, it also offers excellent optical clarity, enabling users to observe color changes, precipitation, or crystallization events in real time. This visual feedback can be essential for troubleshooting reactions and confirming end‑point conditions without opening the vessel.

The material choice of Borosilicate 3.3 glass provides the basin with a high degree of resistance to both acidic and basic environments, allowing it to be used with a wide range of solvents, reagents, and cleaning agents without degradation. It can withstand direct exposure to open flames, making it suitable for use on Bunsen burners, hot plates, and even in microwave-assisted processes. When subjected to rapid temperature changes, the glass’s low coefficient of thermal expansion minimizes the risk of cracking, a property that is highly valued in busy laboratory settings where time‑saving quick‑heat cycles are common. Moreover, the basin can be sterilized in autoclave cycles up to 121 °C, ensuring that it meets stringent hygiene standards required for microbiological work or pharmaceutical applications.

The basin’s crystal‑clear glass also serves as a visual indicator of reaction progress, allowing users to detect color changes, precipitation, or crystal formation without opening the vessel. This transparency reduces the need for additional sampling, thereby minimizing exposure to hazardous vapors. Cleaning the basin is straightforward; the smooth interior surface resists residue adhesion, and it can be rinsed with distilled water or placed in a dishwasher on a gentle cycle. For more stubborn deposits, a mild alkaline solution can be applied, followed by thorough rinsing to ensure no trace of cleaning agents remains.

Usage

In research laboratories, the EISCO 15ml Evaporating Basin is frequently employed for the concentration of reaction mixtures, removal of solvents, and preparation of samples for spectroscopic analysis. Its modest volume is perfect for small‑scale syntheses, where precise control over evaporation rates can influence product yield and purity. Scientists often pair the basin with a rotary evaporator or a simple heating mantle, taking advantage of the flat bottom to achieve consistent heat transfer. The spout’s smooth flow facilitates the collection of the concentrated residue into pre‑weighed containers, enabling accurate mass balance calculations. Because the basin tolerates a broad spectrum of chemicals, it can be used with polar solvents such as water, methanol, and acetonitrile, as well as non‑polar solvents like hexane and toluene, without compromising the integrity of the glass.

In educational settings, the basin serves as an accessible teaching tool for demonstrating fundamental concepts such as evaporation, boiling points, and the effects of temperature on solubility. In high school chemistry classes, instructors can use the basin to illustrate how a flat bottom promotes even heating, while the spout allows students to safely transfer liquids to larger beakers for further experimentation. The clear glass construction helps learners visually track the reduction of liquid volume, reinforcing theoretical lessons with tangible observation. Because the basin is robust and can be cleaned quickly, it withstands the frequent handling typical of classroom environments, making it a cost‑effective addition to school laboratory inventories.

Beyond the laboratory, the basin’s versatile design makes it a valuable asset in home kitchens and craft workshops. Hobbyists who experiment with essential oils, natural dyes, or small‑batch culinary preparations can use the basin to gently evaporate excess water or alcohol, concentrating flavors or pigments without the need for specialized equipment. The spout enables precise pouring into bottles or molds, reducing waste and ensuring a clean finish. Its heat‑resistant glass allows it to be placed directly on stovetops or in ovens for tasks such as reducing sauces, melting wax, or preparing polymer resins. The compact size also means it can be stored easily in drawers or cabinets, freeing up valuable workspace for other tools.

For advanced applications such as thin‑film deposition or micro‑scale crystallization, the basin’s small footprint and precise spout enable researchers to control solvent removal with a high degree of accuracy. When combined with a temperature‑controlled hot plate, the basin can be used to perform gradient evaporation, a technique often employed in the purification of delicate organic compounds. Its compatibility with inert gas blankets also allows for evaporation under reduced pressure or nitrogen atmospheres, expanding its utility to sensitive synthetic protocols that require an oxygen‑free environment.
