Why Must Microbubbles in Materials Be Eliminated?
Residual micro‑bubbles in materials impair end‑product quality.
Electronics IndustryResidual bubbles in conductive silver paste cause dispensing interruption and coating pinholes, resulting in voids and poor insulation after curing. Centrifugal defoaming separates bubbles non‑contact by centrifugal force without introducing impurities, ensuring consistent dispensing performance of conductive paste. | Laboratory & Advanced Material R&DMicro‑bubbles in nano‑dispersion compromise the accuracy of particle size measurement and reliability of dispersion evaluation data. Non‑contact treatment inside sealed containers preserves sample purity, suitable for small‑sample defoaming of test tubes and syringes. | Medical Consumables IndustryBubbles in medical‑grade silicone lead to potting defects, reduced product compactness and fluctuating biocompatibility. No stirrer contact during centrifugal defoaming prevents secondary contamination for clean defoaming of medical consumables. |
✨ Traditional Defoaming Dilemma: Manual stirring entraps air, static defoaming takes long hours, and contact‑type stirring may introduce impurities or modify material properties. The centrifugal defoaming solution separates bubbles via non‑contact centrifugal force without changing material chemical properties, and multi‑tube parallel operation boosts efficiency.
Why Choose SIE‑VH350
Three Core Advantages Cover Small‑Batch Syringe Defoaming Demands
Compact Design with Flexible CompatibilityVH350 occupies small floor space, suitable for laboratory and R&D bench‑top operation. Three container types including tubes, jars and cups are available, covering common syringes and sample tanks within 30‑300mL volume range. | Maximum Expandable Capacity for 16 ContainersComes with four 300CC containers as standard, expandable to 16‑piece parallel defoaming. Multi‑tube parallel processing improves batch efficiency, satisfying both flexible small‑batch operation and multi‑sample simultaneous processing requirements. | Efficient Non‑Contact Defoaming0‑2000rpm stepless adjustment. Centrifugal force separates bubbles without changing material chemical properties. Materials rotate inside sealed containers without direct contact from stirring paddles to prevent secondary contamination. |
✨ VH350 suits small‑batch syringe defoaming requirements for laboratory and R&D scenarios.
Working Principle
High‑speed rotation generates centrifugal force, and gravity assists bubble escape. Materials complete non‑contact defoaming inside sealed containers.
Step 1: High‑Speed Centrifugal Separation Step 2: Gravity‑Assisted Bubble Escape Step 3: Non‑Contact Purity Preservation Inside the sealed container, materials go through the full process of "high‑speed centrifugation → gravity‑driven bubble escape → non‑contact purity preservation" to complete centrifugal defoaming in one single step. | ![]() |

How does the stirring and defoaming machine work?
The SIENOX stirring and defoaming machine performs defoaming through centrifugal force at revolution and stirring through shear force formed by revolution and rotation,
Assisted by a vacuum pump to extract gas and achieve a vacuum state, removing nanoscale tiny bubbles. No contact with materials, no secondary pollution, and no secondary waste.
-
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. It has a wide range of applications, including but not limited to semiconductors, solar energy, optics, biotechnology, materials science, etc.
