How They Work
Both centrifuges operate on the principle of sedimentation, utilizing centrifugal force to separate particles based on density. The YR122 Low-speed Refrigerated Centrifuge leverages its sophisticated cooling system to maintain low temperatures, minimizing the risk of sample degradation during spin cycles. The SORVALL ST 8R reportedly achieves similar results, although its temperature precision is somewhat limited compared to the YR122’s broader range.
Applications
The Kalstein YR122 is broadly applicable across biomedical, clinical, and research laboratories. Its generous capacity and diverse rotor options make it ideal for processing large volumes of samples, be it blood, proteins, or other cellular components. Moreover, its precision cooling system ensures that even temperature-sensitive samples are effectively managed without compromising analytical results.
Types
When evaluating centrifuge types, consider the scope of laboratory processes you perform. Low-speed refrigerated centrifuges like the YR122 are indispensable for applications not requiring ultra-speed centrifugation, favoring sample volume and structural integrity. Conversely, the Thermo Scientific options typically cater to less temperature-sensitive applications, suitable for general purpose centrifugation.
Market Pricing
Centrifuge pricing varies significantly among brands and models. The Kalstein YR122 offers a competitive price point in the market, generally starting at around $12,000, which includes access to the Kalstein Plus platform for automatic quotes and exclusive purchasing efficiency. The SORVALL ST 8R typically starts in the $13,000 range, notwithstanding potential additional costs for accessory upgrades.
