Laboratory Cork Flask Racks – Stable, Non-Slip, Heat-Resistant, and Customizable

Safely arranging glassware in the lab is never a trivial matter. Tianlei Cork offers high-quality cork flask racks, designed specifically for chemistry labs, providing reliable support for beakers, flasks, test tubes, and other glassware. We use 100% natural cork, which is soft yet firm, resistant to high temperatures, acids, and alkalis. Even when exposed to acidic solutions, volatile compounds, or high-temperature lab environments, it remains stable, effectively reducing slippage, scratches, and accidents.

Key Features

✅ Premium Cork, Comprehensive Protection

Using high-grade natural cork, which is both soft and strong, this rack prevents direct contact between glassware and hard surfaces, reducing the risk of damage to instruments. Cork is inherently moisture-resistant, acid-resistant, alkali-resistant, and heat-resistant (up to 120°C), ensuring long-lasting use even in demanding lab environments.

✅ Precision Design, Practical and Thoughtful

Each flask rack features a deep, rounded groove design that fits snugly around the bottom of common vessels. We've widened the base to further enhance overall stability, and the edges are meticulously polished to be gentle on hands and prevent chipping. The inherent elasticity of cork also provides shock absorption, adding peace of mind during daily operations.

✅ Flexible Customization to Fit Your Needs
We understand that every laboratory has unique workflows. Tianlei Cork offers comprehensive customization-whether you require a specific size (such as a large-capacity flask or multi-well test tube rack), a unique shape (round, square, or a combination), or even company logo engraving-we can accommodate it. Laser engraving and thermal transfer technology ensure clear, durable logos that won't fade over time.

▌Use Case Example:
In the lab, researchers are conducting a titration experiment. A technician gently places a freshly heated 500ml Erlenmeyer flask on the Tianlei cork rack. The flask trembles slightly, then stands firmly on the rack, providing a secure, even cluttered lab bench. Nearby, a colleague is using a custom rack emblazoned with the school logo. The neatly arranged vessels prevent confusion during teamwork-professional, practical, and conveying a sense of community. These cork racks silently safeguard the smooth and safe conduct of every experiment.
