The Heart of Your Process Vessel
The agitator is the pulse of your process vessel. In sterile applications, it is the single most critical component for product quality and batch consistency. There is no room for compromise here.
At liquitec, we understand that a reliable process requires a reliable origin. That is why we do not outsource the heart of your machine. Operating from our two high-tech production sites in Switzerland, we manufacture all wetted parts in-house.
This deep vertical integration is the foundation of our Strategic Agility. We do not rely on global supply chains for critical components; instead, we maintain a substantial stock of semi-finished parts, ready for the final steps of customization. This anticipation allows us to bond our manufacturing strengths directly to your process needs: gapless traceability, perfect surface finishes, and adherence to timelines that others cannot match.
Magnetic Agitator Advantages
The Logic of Containment
Protect Your Most Valuable Assets. In modern biotech, there is no room for batch loss. Our hermetic magnetic technology ensures zero leakage, protecting both your potent ingredients and your personnel.
Eliminate the Cost of Maintenance. Stop paying for friction. The bio-m® series replaces high-maintenance mechanical seals with seamless magnetic power. No heat generation, no barrier fluids—just optimized operational uptime.
Liquitecs Advantages
The Definition of Swiss Precision
Machined from Blocks, Not Sheet Metal We strictly utilize subtractive manufacturing from solid stainless steel blocks. This approach eliminates unnecessary welding spots and guarantees structural integrity. It allows us to machine the tightest clearances and minimize air pockets to absolute zero, ensuring the best cleanability in the industry.
Hygiene at the Core (EHEDG) Hygienic design is not just a standard we follow; it is our mindset. Designing with EHEDG guidelines at the core, we achieve surface finishes of Ra < 0.4 μm as our standard. We obsess over details to ensure your vessel remains sterile, with 100% gapless traceability kept strictly in-house.
Precision Beyond the Catalog We do not believe that a standard catalog product is always enough for critical processes. We refuse to serve 100% of the market with 20% of the equipment. We design the agitator to fit your specific needs—adapting geometry and tolerances to your vessel—with no compromises. Just fit for purpose.
Mixing Tasks
Mastering the Physics of Your Process
Every process has a dominant physical challenge. We don't just stir liquids; we engineer the flow pattern to conquer that specific challenge.
- The Task: Achieving rapid uniformity of miscible liquids, often with different densities or viscosities (e.g., Buffer Prep, Media mixing).
- Our Strongsuit: Digital Verification (CFD).
We don't guess your mixing time. For critical blending tasks, we can simulate the process using Computational Fluid Dynamics to guarantee homogeneity is reached before the first batch is ever run.
- The Task: Keeping insoluble particles (crystals, catalysts, or precipitates) in motion to prevent sedimentation at the vessel bottom.
- Our Strongsuit: Our impeller design.
Most agitators simply "move" liquid; ours commands it. Our proprietary impeller design is engineered to generate a sophisticated Axial-Radial flow pattern. By perfectly balancing horizontal distribution with powerful vertical lift, we create a continuous, low-shear cycle that keeps the medium in constant motion.
- The Task: Maximizing the exchange of thermal energy between the product and the vessel jacket (Heating or Cooling).
-
Our Strongsuit: Wall-Flow Geometry.
Standard agitators leave valuable solids trapped in the dead volume. Our Lean Bottom System (LBS) and low-level impellers are engineered to keep solids suspended down to the absolute last liter, maximizing your yield recovery.
- The Task: Breaking down liquid droplets or dissolving difficult powders into a continuous phase (e.g., Oil/Water emulsions).
- Our Strongsuit: High-Shear Options (Rotek & Rotor-Stator).
Standard magnetic mixers often lack the torque for this. We defy the norm by offering high-energy Rotek and Rotor-Stator magnetic heads that deliver the shear rates of a homogenizer with the hermetic safety of a magnetic drive.
- The Task: Gentle movement of sensitive cell cultures or microbial fermentation requiring high Oxygen Transfer Rates (KLa).
- Our Strongsuit: The BMAF Stability.
True performance is born from specialization. We don’t build bioreactors; we perfect the interaction between the impeller and your medium. Our approach is purely process-driven, engineering bespoke impellers that generate the exact axial-radial flow required for your results. By focusing our mastery on this single, critical variable, we ensure your system reaches a level of efficiency and yield that off-the-shelf components simply cannot achieve.
More About Agitation
Engineering Out the Risk
The Billion-Dollar Lesson The North American Mixing Forum estimates that poor mixing costs the process industry between $1 and $10 billion annually in lost yield and wasted energy. Most of these losses occur because mixing was treated as an afterthought. You have the power to avoid this statistic in your new plan.
Solving Symptoms at the Source We often see operators resigned to living with inconsistent batch times, local overheating, or sedimentation. These are not "process realities"; they are physics problems that can be calculated and solved. You do not have to accept a design that forces you to compromise later.
The Solution is Conversation If you are in the planning phase, you have a unique opportunity. By bringing Liquitec to the table before the steel is cut, we can simulate the flow and guarantee the outcome. We bridge the gap between your deep product knowledge and our hydrodynamic expertise to ensure your new vessel performs perfectly from Batch #1.
