How They Work
The Low-speed Refrigerated Centrifuge YR122 by Kalstein operates by leveraging centrifugal force to separate components within a sample based on their densities. Its low-speed functionality coupled with controlled refrigeration ensures that temperature-sensitive samples are handled with care, reducing any potential degradation of sample quality. This model is powered by a stable motor system that guarantees consistent performance.
On the other hand, the Eppendorf 5417 Refrigerated Centrifuge functions at higher speeds, allowing for faster separation times. It is equipped with a reliable cooling system that ensures samples remain at optimal temperatures despite the high-speed movement. This model is ideal for laboratories with high-throughput needs where time is of the essence.
What They Are Used For
Refrigerated centrifuges are indispensable in a variety of laboratory settings. The Kalstein YR122, with its low-speed capacity, is perfect for handling delicate samples such as in molecular biology and protein chemistry, where precise temperature control is critical.
The Eppendorf 5417 is often employed in biochemistry and pharmaceutical labs for tasks requiring fast sedimentation rates, such as DNA or RNA extraction and purification, where its high-speed capability is beneficial.
Types
Centrifuges can be categorized based on their speed (low-speed vs. high-speed), size (benchtop vs. floor-standing), or special features (refrigerated vs. non-refrigerated). Both models discussed here are refrigerated, ensuring sample integrity by maintaining a controlled temperature environment.
Market Price
The market for refrigerated centrifuges presents a wide range of pricing, typically influenced by features, brand reputation, and regional market dynamics. The Kalstein YR122 offers a competitive pricing model, which delivers excellent value for its innovative features and robust design. In contrast, the Eppendorf 5417 is positioned within a higher pricing bracket, reflecting its status and reputation in the industry for high-speed processing.
Frequently Asked Questions
What is the difference between low-speed and high-speed centrifuges?
Low-speed centrifuges are engineered for applications that do not require extremely fast separation, allowing for finer detail in delicate samples, while high-speed centrifuges perform rapid separations for more routine and high-throughput applications.
Why is refrigeration important in a centrifuge?
Refrigeration helps maintain sample integrity by preventing thermal denaturation, which is crucial when working with temperature-sensitive biological molecules.
Can the YR122 handle large volumes?
Yes, the YR122 is designed with capacity flexibility to accommodate larger sample volumes, making it versatile for different laboratory needs.
Advantages and Disadvantages
The Low-speed Refrigerated Centrifuge YR122 boasts several advantages such as user-friendly controls, adjustable cooling, and large capacity handling, providing an edge for labs focused on delicate or temperature-sensitive samples. However, its low speed might be a limitation for projects requiring quick turnaround times.
The Eppendorf 5417 excels with its high-speed functionality and compact design, perfect for labs needing quick, efficient processing. Yet, its higher cost and potential sample limitation due to its medium volume handling might be less appealing for budget-conscious labs or those needing large sample processing.
Field Use
In real-world laboratory environments, both centrifuges perform exceptionally well, with the Kalstein YR122 being favored in settings where sample integrity is paramount, such as genetic research. Its intuitive operation helps streamline laboratory workflows.
The Eppendorf 5417 is preferred in high-pressure laboratory settings requiring efficiency and swift sample processing, like pharmaceutical companies where rapid data acquisition is critical.
