MSK-SFM-20L 20L Planetary Vacuum Mixer with Integrated Vacuum Pump and Temperature-Controlled Water Chiller for Uniform Slurry Preparation
The MSK-SFM-20L is engineered for laboratory and pilot-scale preparation of highly uniform slurries, particularly suited for advanced battery materials such as LiCoO2, LiFePO4, NCM, and ceramic compounds. Its design addresses the challenge of mixing viscous materials without air entrapment by operating under vacuum conditions, ensuring homogeneity and preventing oxidation or contamination during processing.
This planetary vacuum mixer combines multiple stirring motions—revolution, rotation, and planetary movement—with dual stirring shafts and a PTFE scraping blade that continuously cleans the container walls to eliminate dead zones. The integrated water chiller maintains the mixing container temperature between 35ºC and 50ºC, optimizing slurry properties and process stability. The included heavy-duty double-stage vacuum pump achieves vacuum levels up to -0.098 MPa, enhancing mixing efficiency and product quality.
Key Features
- Effective 20-liter stainless steel (SS304) mixing container with water cooling jacket for precise temperature control.
- Dual planetary stirring shafts with independent rotation speeds (2-110 rpm for stirring blade, 100-6000 rpm for dispersing blade) for thorough mixing and dispersion.
- PTFE scraping blade rotates with the main shaft to prevent material buildup on container walls.
- Heavy-duty double-stage vacuum pump included to maintain vacuum levels up to -0.098 MPa.
- Hydraulic lifting system with 300 mm maximum lift height for easy container handling.
- Integrated digital temperature-controlled water chiller with 6-liter tank and 16 L/min flow rate for stable thermal management.
- Multiple fittings including vacuum connectors, sight glasses, ball valve outlet, and vacuum meter for process monitoring and control.

Typical Applications
This mixer is widely used in battery research and development for preparing cathode and anode slurries, including lithium cobalt oxide (LiCoO2), lithium iron phosphate (LiFePO4), and nickel-cobalt-manganese (NCM) materials. It is also suitable for ceramic slurry preparation and other high-viscosity materials requiring uniform dispersion under vacuum.
Configuration & Operating Notes
The MSK-SFM-20L includes a heavy-duty double-stage vacuum pump and a digital temperature-controlled water chiller as standard. The hydraulic lifting system facilitates safe and ergonomic handling of the mixing container. Operators should ensure water pressure for the cooling jacket remains below 40 psi and adhere to recommended minimum stirring speeds for optimal mixing performance. The power plug is not included and must be ordered separately. NRTL certification can be requested at additional cost if required for compliance.
