Serum testing runs on a tight daily schedule, and one poorly spun tube can hold up a result. A low speed centrifuge separates serum from clotted blood with controlled centrifugal force, leaving clear serum ready for analysis. This guide covers how the process works, where it fits in clinical work, and what to review before choosing a unit.
How Serum Separation Works
After blood clots, the clot and cells settle under centrifugal force while clear serum collects above them. A low speed centrifuge machine applies controlled force to separate the clot and cellular components while helping preserve sample integrity.
For this reason, it is a familiar laboratory centrifuge in hospitals, biochemistry departments, and blood centers. A tabletop low speed centrifuge sits on a bench, so technicians can load and unload tubes quickly. The Low Speed Centrifuge LZ-LSC-A104 from Labozon is a stainless steel unit with microcomputer control, a brushless motor, and an automatic electric lid lock.
Applications Beyond Serum
Serum is the main task, but low speed centrifuge uses extend further, and a centrifuge low speed program suits several of them. The product page lists these applications:
- Separating blood serum and plasma
- Separating other biological samples
- Harvesting intact cells, nuclei, and other cellular material
- Collecting chemical precipitates
- Spinning microplates and vacuum tubes with the matching rotors
The page names hospitals, biochemistry departments, and blood centers as its main settings.
Inside the Instrument: Main Parts
A low speed centrifuge diagram usually shows the chamber, the rotor, the drive motor, the lid lock, and the control panel. In the LZ-LSC-A104, a brushless motor drives the rotor, an adjustable axle supports smooth rotor operation, and an LED display shows speed, time, and temperature.l
Studying the diagram before purchase shows how rotors are loaded, how the lid closes, and where service access sits.
Why Clinical Labs Rely on Controlled Spinning
Sample care
Controlled low speed spinning in general helps keep cells intact and the serum clear.
Lid safety
The page states that the automatic electric lid lock controls speed and helps limit contamination.
Saved programs
The page lists 10 programs and 10 acceleration and deceleration profiles, with quick speed-up and slow-down from the brushless motor.
Rotor options
Swing, fixed angle, and microplate rotors cover different tube sizes, and the page notes low maintenance with no powder pollution.

Common Selection Mistakes
Choosing on capacity alone is the most frequent error. Review rotor options, tube capacity, lid safety, noise, bench footprint, and program storage together. A low speed table top centrifuge that matches your daily tube volume prevents queues and repeat spins.
Other mistakes include buying without checking rotor availability, ignoring service support, and overlooking bench space. If your work also needs higher speeds or refrigeration, review the wider laboratory centrifuge range before deciding.
Swing vs. Fixed Angle Rotors
| Factor | Swing rotor | Fixed angle rotor |
|---|---|---|
| Tube position | Tubes swing out to horizontal | Tubes held at a set angle |
| Typical use | Serum tubes and layered separations | Pelleting cells and precipitates |
| Pellet shape | Pellet forms at the tube bottom | Pellet forms along the tube wall |
| Page listing | Several buckets and adapters | Several tube capacities |
User Tips and Recommended Practices
- Let blood clot fully before loading, as your lab procedure describes.
- Balance tubes in opposite positions, using matching tubes and volumes.
- Use only the rotor and adapters made for your tube type.
- Set speed and time for each sample type, and record the settings.
- Place the unit on a level, stable bench with space around it.
- Wait for the rotor to stop completely before opening the lid.
- Wipe the chamber and rotor after each shift, and clean spills right away.
- Inspect rotors and buckets on a schedule, and log each check.
