Description
Product Overview
Sommer Cork presents a premium set of tapered cork stoppers designed specifically for laboratory applications. Each stopper measures a top diameter of 1 1/4 inch and a length of 1 1/4 inch, providing a precise fit for standard glass containers used in chemistry, biology, and environmental testing. The cork material is harvested from the forests of Portugal, where sustainable practices ensure that the natural ecosystem remains balanced while delivering a product that is both reliable and environmentally responsible.
The natural elasticity of cork allows the stopper to expand gently within the bottle neck, creating an airtight seal that prevents evaporation, contamination, and pressure loss. Because the product is 100% natural, it does not react with chemicals, making it safe for a wide range of solvents, acids, and reagents. The pack contains ten individual stoppers, each individually inspected for consistency in size and density, guaranteeing uniform performance across all laboratory procedures.
Usage
These tapered cork stoppers are ideal for sealing reagent bottles, sample vials, and storage flasks in academic, industrial, and clinical laboratories. Their tapered design facilitates easy insertion and removal, reducing the risk of breakage or spillage during routine handling. Researchers can rely on the corks to maintain a stable environment for sensitive compounds, protecting them from moisture and airborne contaminants.
Beyond traditional laboratory settings, the stoppers are suitable for educational demonstrations, field research kits, and small‑scale production environments where a cost‑effective, reusable sealing solution is required. The natural cork material also offers a degree of thermal insulation, helping to moderate temperature fluctuations in stored solutions. Users appreciate the simplicity of the design, which eliminates the need for additional sealing accessories or complex mechanisms.

FAQ
What types of containers are compatible with these cork stoppers?
The stoppers are designed to fit standard laboratory bottles and flasks with a 1 1/4 inch neck opening. They work well with glassware used for solvents, acids, bases, and biological samples, providing a secure seal for both small and medium‑size containers.
Are the corks suitable for high‑temperature applications?
Cork has a natural resistance to moderate temperature changes and can tolerate typical laboratory heating processes. However, for extreme high‑temperature applications exceeding 200 °C, a specialized sealing material may be more appropriate.
How does the sustainability of the cork impact laboratory safety?
Sustainably sourced cork is free from synthetic additives, reducing the risk of chemical leaching into stored solutions. Its natural composition also means it is biodegradable at the end of its life cycle, aligning with green laboratory initiatives.
Can I purchase larger quantities for a research facility?
Yes, Sommer Cork offers bulk ordering options and can provide customized packaging to meet the needs of larger institutions. Contact our sales team for volume pricing and delivery arrangements.
What should I do if a stopper becomes damaged or deformed?
In the unlikely event that a stopper shows signs of damage, please reach out to our customer service team. We will assess the issue and provide a replacement or refund according to our warranty policy, ensuring uninterrupted laboratory operations.
