Mini Benchtop Centrifuges – Fixed and Variable Speed Models
Mini benchtop centrifuges — compact, quiet, and highly precise. Available in fixed and variable speed versions, ranging from 4,000 to 15,000 rpm, they provide reliable and safe performance for the separation of microtubes and biological samples.
Ideal for clinical, educational, and research laboratories, they feature an ergonomic design, transparent safety lid, and interchangeable rotors compatible with multiple applications.
Mini Benchtop Centrifuges – Fixed and Variable Speed Models
The mini benchtop centrifuges are the ideal solution for laboratories seeking performance, safety, and precision in a compact design. With their ergonomic shape, quiet operation, and advanced technology, they allow fast and efficient sample separations while saving valuable bench space.
Manufactured by Nahita and RS Lab, these centrifuges combine high-resistance materials with advanced control systems that ensure rotor stability, dynamic balance, and user protection. They are perfect for microfiltration, HPLC, PCR, clinical analysis, and biological or chemical research.
Available in fixed-speed and variable-speed models, these mini centrifuges adapt to a wide range of laboratory applications — from routine educational work to professional tasks requiring precise rotational control. Models with brushless motors stand out for their longer lifespan, low maintenance, and even quieter, smoother operation.
The transparent safety lid with automatic lock prevents accidental opening during rotation, while soft start and stop systems protect sample integrity. All models allow quick rotor exchange without tools, improving workflow efficiency.
