When working in a laboratory, we know that sample preservation is one of the most critical aspects. Ultra-low freezers and refrigerators are essential for maintaining the integrity of biological samples, reagents, and other elements that need to be stored at extremely low temperatures. Storage at -80°C is the standard for many types of samples, such as DNA, RNA, proteins, and cell cultures, as it prevents degradation and ensures long-term stability.
Refrigerators and Freezers, Kalstein Brand
In my experience, Kalstein’s ultra-low freezers have proven to be of high quality, providing reliable performance even under the most demanding conditions. These units are ideal for laboratories that require secure and controlled storage at temperatures as low as -80°C. What stands out about Kalstein is their ability to offer products that meet high international standards at competitive prices, making their equipment an attractive option for both small labs and large research institutions.
Additionally, their ergonomic design and energy efficiency make them a preferred choice in the market. The ease of use, combined with the ability to store large volumes of samples, has been a key advantage in my lab. Compared to other brands, Kalstein’s ultra-low freezers offer excellent value for money.
Technical Features of Refrigerators and Freezers
Kalstein’s ultra-low freezers stand out for their precise temperature control and robust design, ensuring constant protection for samples. Some of the technical aspects I appreciate the most include:
