2-16KL Refrigerated Centrifuge Key Features

❄️ Advanced Refrigeration System

The Sigma 2-16KL is equipped with a powerful, environmentally friendly refrigeration unit capable of maintaining temperatures from –10°C to +40°C. This precise temperature control is critical when working with heat-sensitive biological samples or chemicals that require consistent cooling throughout centrifugation.

🌀 High-Speed Performance with Low Noise

Despite its compact size, the 2-16KL delivers impressive centrifugation speeds of up to 15,300 RPM (depending on rotor type) with relative centrifugal forces (RCF) up to 21,913 x g. The unit also operates with minimal vibration and low noise, enhancing the laboratory working environment.

🔁 Wide Rotor Compatibility

One of the most appreciated features is the wide selection of swing-out and fixed-angle rotors, allowing users to process a variety of tubes and containers—from microtubes and conical tubes to blood collection tubes and culture bottles. Its universal adaptability makes it ideal for both clinical and research applications.

2-16KL Refrigerated Centrifuge User-Friendly Interface

 The digital display provides real-time information about speed, RCF, temperature, and run time. You can easily set and store multiple programs to suit recurring protocols, saving time and minimizing setup errors.

Additional features include:

• Rapid acceleration and deceleration settings

• Automatic rotor recognition and imbalance detection

• Soft-touch lid locking system for user safety

• Pre-cool function to prepare the chamber before use
