Shengwin Lab Large Capacity Electric Centrifuge – Model SN-LSC-40S (100ml × 4)

This is a used Shengwin (also associated with SUNNE branding) low-speed laboratory centrifuge, model SN-LSC-40S, configured with a large-capacity rotor supporting 4 × 100 ml tubes. It is a reliable benchtop unit designed for efficient sample processing in professional laboratory environments. The centrifuge is in used condition and has been previously employed in laboratory applications.

Intended Applications

This low-speed centrifuge is well-suited for a variety of standard laboratory procedures, including:

• Separation of serum, plasma, and other blood components
• Sample preparation in clinical, biological, and chemical research
• Fat separation and skim milk processing
• Polysaccharide extraction and similar biochemical protocols
• General-purpose low-speed centrifugation of larger-volume samples in research and educational labs

It excels in handling batch processing where moderate centrifugal forces are required for gentle yet effective separation.
