First Use Experience
My first test involved concentrating DNA extracted from soil samples collected during a simulated survival scenario in a heavily wooded area. I needed to quickly isolate and amplify the DNA to identify potential pathogens present in the environment. The Eppendorf Rotor F-45-48-11 was put to work with the Vacufuge Concentrator.
The rotor performed flawlessly, maintaining consistent speed and temperature throughout the concentration process. The ease of loading and unloading the 1.5/2.0 mL tubes was also notable, and the stackable tube design proved advantageous. I was initially concerned about potential sample loss due to bumping or foaming, but the Vacufuge’s automatic vacuum release system effectively prevented this.
Extended Use & Reliability
After several months of consistent use, the Eppendorf Rotor F-45-48-11 continues to perform reliably. There are no visible signs of wear or tear, even after repeated exposure to various chemicals and cleaning solutions. The rotor is simple to clean with a mild detergent and water, requiring minimal maintenance.
Compared to my previous method of using a single-tube concentrator, the Eppendorf Rotor F-45-48-11 has dramatically increased my throughput. It has cut down the time for sample preparation, allowing me to focus on data analysis and interpretation. The consistent performance and ease of use have made it an indispensable part of my workflow.
Breaking Down the Features of Eppendorf Rotor F-45-48-11, 48 Places For 1.5/2.0 mL Reaction Vessels
Specifications
- The Eppendorf Rotor F-45-48-11 is designed to hold 48 x 1.5-2.0 mL (11 x 40 mm) microcentrifuge tubes. The high capacity is a key feature for high-throughput labs.
- It’s specifically designed for use with Eppendorf Vacufuge Concentrators, ensuring optimal compatibility and performance.
- The rotor’s rotational speed is rated at 1400 RPM, providing sufficient centrifugal force for efficient sample concentration. This speed is critical for quickly removing solvents and concentrating the target molecules.
- The maximum RCF (Relative Centrifugal Force) is 240 g, sufficient for concentrating most biological samples without damaging them.
- It’s compatible with three heating levels: 30, 45, 60°C (86, 113, 140°F), or ambient. This feature allows for precise control over the evaporation rate, optimizing the concentration process for different types of samples.
These specifications are important because they directly impact the rotor’s ability to efficiently and reliably concentrate samples. The high capacity and optimized rotational speed ensure that a large number of samples can be processed quickly, while the temperature control feature allows for precise optimization of the concentration process.
