Don't Leave Money in the Tank

In high-value pharmaceutical processing, the most expensive volume is the "Heel"—the product left behind because standard agitators cannot mix the final liters. Conventional design forces you to write off this residual volume as unavoidable waste.

We disagree. Leaving active ingredient in the tank every single batch is not a "process reality"; it is money left on the table. In this case in the tank.

The bio-m® Lean Bottom System (LBS) reverses this logic. We have engineered the vessel floor as a single symbiotic unit—integrating the agitator, the bottom outlet valve, and up to two Ingold ports into one pre-fabricated block

For your Vessel Builder, this eliminates complex welding work and validation risks. But for you, the Process Owner, it delivers the ultimate return: full homogeneity and drainability down to the absolute last drop. You recover almost 100% of your valid product, every single batch

Advantages

Designed for the Owner. Loved by the Builder 

Yield loss is often viewed in isolation, but in a multi-stage pharma process, it compounds. 

  • The Problem : Standard agitators stop mixing once the level drops below the blade, forcing you to discard the "heel" volume. In a 3-stage process train, this can waste almost 30% of the batch or in 500 liters you lose almost 140 liters.
  • LBS Solution : Our deep-set impeller maintains full turbulent flow and homogeneity down to the absolute last drop. You recover almost 100% of your valid product, every single batch. In a couple of batches, this system pays for itself in recovered yield alone.

There is a difference between "moving" liquid and "mixing" it. Standard magnetic mixers lose their mixing vector at low levels, leading to stratification (separation of ingredients). The LBS ensures that even the final liter of product exiting the tank is perfectly homogenous, ensuring your fill-finish quality is consistent from start to finish.

In sterile processing, a piping intersection is a risk. A "dead leg" is a biological incubation zone. 

  • The Liquitec Standard :  We engineered the LBS valve block to exclude dead legs completely. The flow path is flush, fully drainable, fully cleanable, and actively swept by the mixer.
  • The Result : You eliminate the primary source of cross-contamination between batches. Your cleaning validation becomes simpler, and your patient safety margin increases.  

We make it easy for your vessel manufacturer to give you a perfect tank

  • The Reality : Welding multiple flanges (Mixer, Valve, Drain, Sensors) into a dished bottom causes heat distortion, warping, and polishing headaches.
  • The Advantage : By delivering the LBS as a single, pre-fabricated Multi-Port Master Flange, we reduce your tank builder's welding work substantially. This minimizes the risk of vessel warping and ensures your critical bottom geometry is factory-perfect before it even arrives at your site.
