Why the 900ML Vacuum Planetary Gravity Mixer Is the Essential Tool Your Lab Has Been Missing

In R&D labs and small-batch production, two mixing headaches are universal: uneven dispersion and stubborn micro-bubbles. Mechanical stirrers create dead zones, contaminate samples, and demand tedious cleanup. The subit 900ml Planetary Gravity Mixer Vacuum Stirring Defoaming Machine solves all three—without a single blade touching your material.
How it works: Dual cups revolve at up to 2000 RPM while rotating on their own axes, generating centrifugal forces that push material outward and shear it inward. This planetary motion achieves homogeneous mixing in 1–3 minutes. Simultaneously, a vacuum pump pulls down to -100 kPa, evacuating submicron bubbles that heating or degassing can't remove.

Key specs at a glance:

Two 900ml containers, optimal fill 10–540ml each
Speed: 100–2000 RPM (revolution) with fixed rotation ratio
5 programmable recipes × 5 steps each
Vacuum: -100 kPa; protections: door, overload, breakdown
Footprint: 690×580×610mm, 120kg, runs on 220V single-phase

Why buyers choose this over blade mixers:

Zero cross-contamination – sealed containers, no agitator contact
No cleanup – swap cups and run the next batch instantly
Material integrity – no excessive shear, ideal for adhesives, battery slurries, silicone, inks, and optical coatings
Real-world applications: From LED encapsulants and thermal pastes to lithium-ion electrode slurries and medical silicones—this machine handles viscosities from thin inks to thick pastes with repeatable precision.

Short but powerful: The touchscreen interface stores your exact parameters, ensuring batch-to-batch consistency. Safety interlocks and overload protection give peace of mind during high-speed runs.
For labs that value speed, cleanliness, and defect-free results, this 900ml planetary vacuum mixer delivers production-grade performance in a benchtop footprint. Ready to ditch bubbles and blades? Reach out for a demo or application consultation.
