SK-300SII Planetary Centrifugal Mixer – Precision Mixing & Defoaming in One Compact Unit
The SK-300SII from Shashin Kagaku Co., Ltd. is a next-generation planetary centrifugal mixer designed for precise mixing and defoaming of materials with different viscosities and specific gravities. Equipped with an individual revolution and rotation speed control system, it offers up to 90 unique speed combinations, enabling optimized settings for a wide variety of applications—from adhesives and conductive pastes to cosmetic pigments and coatings.
1. Capacity: 300ml × 1 cup / Max. 310g (gross weight)
2. Revolution & Rotation Control: Independently adjustable—9 revolution steps × 10 rotation steps
3. Three Operation Modes:
- Mixing Mode – Standard high-speed mixing
- Medium Mode – Minimizes heat generation during mixing
- Degassing Mode – Optimized for bubble removal
4. Wave Mode: Enhances dispersion force for challenging materials
5. Balance Navigation: Detects imbalance and assists in balancing the load
6. Non-contact Mixing: No propellers, no cleaning required, zero material loss
7. Safety Features: Lid lock, operation lock, unbalance detection, motor warning & maintenance alerts
Advantages Over Conventional Mixers
・No material damage or contamination – Unlike propeller and roller mixers ・Shorter processing times – From tens of seconds to a few minutes ・Handles a wide viscosity range – From low-viscosity liquids to high-viscosity pastes ・Continuous Operation: 5-step operation settings allow stable long-duration use⚡Electronics: Conductive paste mixing for PCB manufacturing
?Cosmetics: Pigment dispersion for foundations, lipsticks, nail polish
?Automotive: Thermal grease preparation, adhesive blending
?Medical: Silicone preparation for dental and device applications
?Coatings & Inks: Uniform mixing of high-viscosity printing inks and specialty coatings
Mode setting according to the application 
SK-300SII, the new medium mode has been added to the existing "mixing mode/degassing mode". 
The balance can be adjusted easily for the unbalance detection and balance navigation functions.
Easy operation keeps same, it offers a wider range of applications, and a selection of modes suited for the material.
Equipped with a balance navigation function
The balance can be adjusted easily for the unbalance detection and balance navigation functions. 
Compatible with 300 ml containers/max. 310 g
Despite its compact size, this model can be used to process 300 ml containers weighing a maximum of 310 g (gross weight)!!
Designed with a full range of safety functions
This unit is designed with such considerations for safety as top lid lock, operation lock during while the lid is open and a malfunction prevention mechanism. In addition, the unbalance error detection and a full range of functions for warning and notifying of motor problems or maintenance set alarm with peace of mind.
