Why Planetary Mixing Is Required
Uneven mixing and dispersion of slurry directly impair end‑product performance.
Paint & Pigment IndustryUneven dispersion of pigment powder and resin base material in paints and pigments causes color difference, insufficient hiding power and gloss fluctuation. The planetary mixer generates intense kneading interference for medium‑high viscosity color paste via compound revolution‑rotation motion. The high‑speed dispersing disc shears pigment agglomerates down to micron level, ensuring dispersion fineness and color consistency of lab‑scale color paste for reliable and reproducible formula optimization data. | Biomedicine IndustryUneven mixing of active ingredients and substrates in pharmaceutical systems such as ointment preparations and biological gels results in content deviation and unstable release rate. Kneading interference motion from low‑speed mixing paddles of the planetary mixer achieves homogeneous blending of high‑viscosity ointment substrates. Vacuum environment isolates air and moisture contamination. The temperature sensor delivers ±0.5℃ precise temperature control to prevent thermal‑sensitive components from deactivation and guarantee consistent quality of small‑batch trial products. | Thermal Conductive Material IndustryPoor dispersion between thermal conductive powder and silicone oil in thermal grease and thermal gel leads to thermal conductivity fluctuation and uneven coating thickness. The high‑speed dispersing disc of planetary mixer uniformly disperses high‑loading thermal conductive powder into silicone oil matrix. Low‑clearance design eliminates settling dead zones. Vacuum defoaming removes bubbles introduced during mixing, making thermal performance and coatability of thermal‑material samples meet design requirements. |
✨ Traditional mixing challenges: Conventional single‑shaft mixers feature numerous dead zones. Materials climb and adhere to vessel walls, resulting in uneven mixing of high‑viscosity slurry. Single mixing mode cannot realize mixing and dispersion simultaneously, making agglomerated particles hard to break up. Open‑type mixing introduces bubbles and impurities to contaminate slurry and impair performance. Imprecise temperature control causes slurry heat rise during mixing and alters rheological properties. Without vacuum function, internal bubbles inside slurry cannot be eliminated.
Why Choose SIE‑GX1L
Solve Core Pain Points of Lab‑Scale Formula Optimization
Smooth Process Scale‑up for Lab‑Scale CapacityThe enhanced helical frame paired with wall‑scraping paddles and low‑clearance design generates intense material kneading interference and omnidirectional circulating motion, achieving dead‑zone‑free mixing without material climbing even for 1L batches. The cantilever‑type screw lifting vessel enables fast and convenient material replacement and cleaning, ideal for frequent formula switching in lab‑scale R&D. | Fine Polishing via High‑Speed DispersionThe high‑speed dispersing shaft is equipped with serrated dispersing disc, featuring variable frequency speed from 0 to 5000r/min with maximum linear speed up to 15m/s. The high‑speed dispersing disc powerfully shears and breaks agglomerated particles for fine material dispersion. Low‑speed mixing and high‑speed dispersion work synergistically to complete mixing and dispersion in one step, making lab sample slurry fineness meet requirements directly. | Integrated Vacuum Defoaming & Precise Temperature ControlEquipped with an oil‑free vacuum pump to remove internal slurry bubbles during mixing. The direct‑contact temperature sensor achieves a measurement error of only ±0.5℃ with fast response. Supporting both heating and cooling, it accurately controls slurry temperature and prevents rheological property changes caused by mixing heat. The fully vacuum‑sealed design isolates air and moisture contamination throughout mixing. |
✨ If your lab‑scale laboratory needs a planetary mixer with moderate capacity, high dispersion performance for simultaneous mixing and defoaming, the GX1L is your ideal choice.
Working Principle
Both low‑speed mixing paddle and high‑speed dispersing disc perform rotation and revolution to realize mixing and dispersion simultaneously.
Step 1: Revolution and Rotation of Low-speed Stirring Paddle Step 2: Shearing and Dispersion by High-speed Dispersing Disc Step 3: Vacuum Defoaming & Temperature Control Three simple steps: Low-speed revolution & rotation mixing → High-speed shear dispersion → Vacuum defoaming, temperature control and discharging. Mixing, dispersion and defoaming are completed in one process. | ![]() |

What is the function of a defoaming machine?
A defoaming machine is a device used to remove bubbles from liquids. Its function is to assist in the liquid mixing, reaction, coating, printing, infusion and other process steps in the production process, avoiding the generation of bubbles and their impact on the final product. In many industrial and laboratory environments, removing bubbles is essential as they may have a negative impact on product quality, such as affecting surface tension and stability. Defoaming machines typically use various techniques such as vibration, ultrasound, centrifugation, etc. to achieve effective bubble removal.
