Frequently asked questions
How many tubes does the fixed-angle rotor hold?
The PowerSpin BX C881 utilizes a durable Fixed Angle 8 Place Metal Blood Tube rotor, specifically designed for high-capacity blood processing. It is engineered to maximize throughput while ensuring safety and reliability.
Key specifications for the rotor include:
- Capacity: It holds up to 8 tubes simultaneously.
- Tube Compatibility: The rotor accommodates standard 10 ml or 12 ml tubes, with a maximum size of 17 x 105 mm.
- Performance: When running at maximum speed (5,000 RPM), the rotor achieves a maximum Relative Centrifugal Force (RCF) of 2570 g.
Does the centrifuge have advanced safety features?
Yes, the Unico PowerSpin BX C881 Centrifuge is equipped with advanced safety mechanisms to ensure exceptionally secure and reliable operation in the laboratory.
These critical safety features protect users, samples, and the equipment itself:
- Zero RPM Lid Lock: The lid cannot be opened until the rotor has completely stopped spinning.
- Auto Unbalance Detection and Shutdown: The system automatically detects rotor imbalances and initiates an immediate shutdown to protect the unit and samples.
- Rotor Recognition and Shutdown: Verifies correct rotor installation and automatically shuts down if an issue is identified, ensuring enhanced operational security.
Does the centrifuge have precise speed control?
Yes, the Unico PowerSpin BX C881 provides precise, digitally controlled variable speed operation using an intuitive push-button interface and an oversized LCD display that shows real-time operational data. This ensures reliable and efficient separation protocols.
Key performance specifications include:
- Speed Range: Variable from 1,000 up to 5,000 RPM (with the included Fixed Angle 8 Place Metal Blood Tube Rotor).
- Maximum Force: It achieves a maximum Relative Centrifugal Force (RCF) of 2,570 g.
- Motor: The unit is driven by a powerful, super quiet, and maintenance-free Brushless DC Motor.
- Timer: Features a Digital Timer adjustable from 0 to 99 minutes.
Is the exterior easy to clean?
Yes, the exterior of the centrifuge is designed for high standards of laboratory hygiene. The casing material is chemical resistant, ensuring it is easy to clean and disinfect as required in professional medical and scientific environments.
Does it feature a maintenance-free motor?
Yes, the Unico PowerSpin BX C881 Centrifuge features a powerful, high-quality maintenance-free Brushless DC Motor.
This design is a key selling point, offering significant advantages for laboratory use:
- Zero Maintenance: It requires minimal upkeep, ensuring reliable operation without the hassle of routine motor maintenance.
- Quiet Performance: The motor is engineered for super quiet operation, contributing to a better working environment.
- Longevity: Brushless DC motors are known for their long-term dependability and efficiency.
What voltage options are available?

Available voltage options include:
- 110 V / 60 Hz (Model C881)
- 220 V / 50 Hz (Model C881E)
What is the maximum RCF separation force?
The Unico PowerSpin BX C881 is a high-performance centrifuge capable of generating a significant Relative Centrifugal Force (RCF), essential for efficient sample separation with the standard Blood Tube rotor.
- Maximum RCF: The centrifuge achieves a powerful maximum RCF of 2570 g.
- Operating Speed: This maximum force is reached when operating at the top variable speed of 5,000 RPM.
- Precise Control: The unit is designed for versatility, offering a variable speed range from 1,000 RPM up to 5,000 RPM for various protocols.
Is a precise digital timer included?
Yes, the Unico PowerSpin BX C881 Centrifuge is equipped with a precise digital timer to ensure accurate sample processing. The digital timer range is adjustable from 0 up to 99 minutes and the current setting is clearly displayed on the oversized LCD.
Is an easy-to-read display included?
Yes, the Unico PowerSpin BX C881 Centrifuge features an oversized LCD display.
This display is designed for user-friendly operation, providing clear, real-time data viewing, which allows you to easily monitor and adjust parameters such as the speed (RPM) and the digital timer.
Does this centrifuge efficiently process blood tubes?
Yes, the Unico PowerSpin BX C881 is specifically engineered for efficient processing of clinical blood samples and is ideal for routine separation tasks. It includes features optimized for this application:
- Dedicated Rotor: It comes standard with a Fixed Angle 8 Place Metal Blood Tube rotor.
- Capacity: The rotor accommodates 8 tubes, fitting common sizes of 10 ml or 12 ml (maximum test tube size is 17 x 105 mm).
- Performance: It offers a variable speed range of 1,000 to 5,000 RPM, achieving a maximum Relative Centrifugal Force (RCF) of 2570 g.
- Motor Quality: Operation is powered by an exceptionally quiet, maintenance-free Brushless DC Motor, ensuring reliability and minimizing noise in the lab environment.
