FAQs

1. What is the maximum sample volume that can be processed in the centrifuge?

The maximum sample volume depends on the type of rotor used with the centrifuge. Typical rotors can accommodate sample volumes ranging from 0.2 mL (microcentrifuge tubes) to 50 mL (conical tubes) or larger for specialized rotors. It is important to check the centrifuge's specifications and rotor compatibility to ensure that the sample volume does not exceed the recommended limits, which could affect centrifugation efficiency and safety.

2. How to balance the centrifuge before operation?

Proper balancing is critical for safe and effective centrifuge operation: 1) Ensure that all sample tubes have the same volume and weight; 2) Place the tubes symmetrically in the rotor, opposite each other; 3) For odd numbers of samples, use a balance tube filled with the same volume of appropriate solution; 4) Check that the rotor is properly seated and secured in the centrifuge; 5) Avoid overloading the rotor beyond its maximum capacity.

3. What is the difference between relative centrifugal force (RCF) and revolutions per minute (RPM)?

RCF is a measure of the centrifugal force applied to the sample, expressed in multiples of gravity (x g), and depends on both the RPM and the radius of the rotor. RPM is a measure of the rotor's rotation speed in revolutions per minute. The relationship between RCF and RPM is given by the formula: RCF = 1.118 × 10^-5 × r × RPM² (where r is the rotor radius in centimeters). For most applications, RCF is the preferred parameter as it directly relates to the separation efficiency, regardless of rotor size.

4. How to maintain the centrifuge to ensure long service life?

Regular maintenance includes: 1) Cleaning the rotor and chamber after each use to remove sample spills and debris; 2) Inspecting the rotor for cracks, corrosion, or wear before each use; 3) Lubricating moving parts according to the manufacturer's recommendations; 4) Calibrating the speed and temperature controls annually or after major service; 5) Ensuring proper ventilation around the centrifuge to prevent overheating; 6) Storing the centrifuge in a clean, dry environment when not in use.

5. What safety precautions should be taken when using the centrifuge?

Important safety precautions include: 1) Always balance the sample tubes properly before operation; 2) Ensure the rotor is correctly installed and secured; 3) Do not open the centrifuge lid while the rotor is still spinning; 4) Use appropriate personal protective equipment (gloves, goggles) when handling samples and cleaning the equipment; 5) Avoid overloading the centrifuge beyond its maximum capacity; 6) Regularly inspect the centrifuge for any signs of damage or malfunction and discontinue use if any issues are found.

1. How does the imbalance detection system enhance operational safety in the Low Speed Centrifuge ?

Low Speed Centrifuge integrates a three-axis gyroscopic imbalance detection system, which continuously monitors rotor balance in real time. This system not only prevents mechanical strain or failure due to unbalanced loads but also enhances user safety by automatically halting operation in the event of irregular vibration or instability, especially during high-speed spins with uneven sample distribution.

2. What level of user control does the Low Speed Centrifuge offer through its programmable settings?

Low Speed Centrifuge includes over 12 user-programmable memory slots, allowing operators to store and recall frequently used protocols. This feature is particularly beneficial in settings where standardization and repeatability are critical, such as diagnostic labs or pharmaceutical production environments. Stored programs reduce setup time, minimize user error, and promote consistent sample handling.

3. How is the motorized electronic door of the Low Speed Centrifuge beneficial in daily lab operations?

The motorized electronic door system of Low Speed Centrifuge adds convenience and safety by automating the opening and closing mechanism. It eliminates the need for manual force, reducing the risk of lid-related injuries or stress on mechanical parts. It also integrates seamlessly with the centrifuge's internal safety protocols, ensuring that the door remains locked during operation and only unlocks when rotor motion has fully ceased.

4. What types of rotors are compatible with the Low Speed Centrifuge , and how does this impact its versatility?

This Low Speed Centrifuge supports an extensive range of 17 swing-out rotors and 2 microplate rotors, accommodating volumes from 1.5 mL to 500 mL and formats including blood tubes, conical tubes, tubes, and microplates. This adaptability allows the centrifuge to be configured for routine clinical diagnostics, high-throughput sample processing, or research involving different vessel types, all using a single platform.
