Eppendorf® Erlenmeyer Clamps with Spring Retainer are precision-engineered accessories designed to securely hold Erlenmeyer flasks and compatible vessels on universal shaker platforms. Built for exceptional durability and reliability, these clamps ensure stable performance during orbital shaking, preventing flask movement and vibration even at high speeds.
Each clamp features a spring retainer mechanism for quick, secure placement and removal of flasks, enhancing workflow efficiency in microbial, cell culture, and biochemical applications. The clamps are compatible with a wide range of Eppendorf Innova® and Excella® biological shakers, as well as other standard shaker models that support Eppendorf universal platforms.
For non-standard vessels such as Thomson Ultra Yield®, Optimum Growth™, Tunair®, Corning®, DURAN®, or TPP® Bioreactors, refer to the Eppendorf Shaker Accessory Guide to ensure compatibility and optimal platform configuration.
Key Features
- Secure Spring Retainer Design: Provides firm grip and stability during high-speed orbital shaking.
- Durable Stainless-Steel Construction: Corrosion-resistant and long-lasting for routine laboratory use.
- Wide Flask Compatibility: Supports Erlenmeyer flasks from 25 mL to 6 L and select bottle or bioreactor formats.
- Easy Installation: Mounts directly onto universal phenolic resin or aluminum platforms.
- Optimized for Eppendorf Innova® and Excella® Series Shakers: Ensures reliable performance and precise flask alignment.
- Versatile Application: Suitable for microbiology, cell culture, protein expression, fermentation, and media preparation.
