Scale-up Advantages Compared to Competitors

Modular design, and the use of interchangeable components is common in aerospace, car, electronics etc industry. But only AECS-QuikPrep and Couturier have employed this concept to countercurrent chromatography. We did to ensure success in scale-up..
Please consider visiting our NEW DEMONSTRATION LABORATORY near Newquay Airport, only 1 hour flight from London Gatwick, and with good connections to many National & International Airports.

Please consider requesting Dr Leslie Brown visiting you to discuss your larger scale process needs.

If you are interested in collaborative research, please suggest a topic. We are particularly interested in high pressure SFE / SFC / SFC-MS / L-LC direct to MS applications, but have a general interest in many subjects from trace to process quantities.

High backpressure, Stainless Steel coiled 18-litre Quattro ProcessPrep™ HPL-LC™ unit start from LESS THAN HALF PRICE of low backpressure PFA coiled (only ~105psi), 18 litre UK competitors’ process HPCCC units? Being modular the process Quattro HPL-LC™ (starting from 3 litres), allow you to start your process chromatography or extraction with at low-cost with one unit. Add capacity only as required. Perfect for Simulated Moving Bed use. Like to have different bobbins sets with different bores / volumes for different requirements or SMB? You can with Quattro Process HPL-LC™, but not with competitors.

New Quattro HPL-LC™ Mk 8 typical sample preparation times are only 20 to 60+ minutes. Solvent usage for same mass injected can be up to 90% less than Flash or HPLC,
and also 40 to 90% often less than many CCC / HSCCC / HPCCC / CPC / HPCPC, from HSCCC / HPCCC competitors.

Our unique modular design means that you can have an instrument custom made to your needs and budget.

Partitron & Quattro HPCPC™ ATEX approved, Intrinsically Safe units are worldwide the only HPCPC (High Performance Centrifugal Partition Chromatography) with TITANIUM ROTOR OPTIONS and STOPPED USE OF ANY LEAK-PRONE PTFE SEALS, so suitable steam cleaning. Many of our competitors only have units where their parent academic University / Research Institute shareholders obtained grants for “one-off” builds. We have supplied industrial process units for several years.

The modular Process Compatible, ATEX specification, Quattro HPCPC start at 6 litre modules & ATEX Partitron HPCPC™ range begins at 25 litre units. Scale-up “in-parallel” by use of multiple 6 or 25 litre units easily available. Add capacity with additional modular 6 or 25 litre rotors as & when required.

Or consider our Process HPCPC for Simulated Moving Bed use, standard solvent or IONIC LIQUID solvents or Liquid CO2 use for CHROMATOGRAPHY OR EFFICIENT EXTRACTION.

Do you need Centrifugal Partition Chromatography Process Scale-up?
Centrifugal Partition (Hydrostatic CCC) Chromatography

Quattro and Partitron Hydrostatic CCC (CPC) models (historically called high performance centrifugal partition chromatography) offer the options of 6 or 10 mm cell bores in laboratory units, plus 10, 15 or 22 mm cell bores for the 5 to 18+ litre capacity Quattro HPCPC™, or 22m for Partitron HPCPC™. These instruments can be utilised with standard and slow-settling biphasic solvents. Examples of latter: aqueous / aqueous (PEG or Dextran) mixes, and butanol based mixes. Typical applications would be MAB’s, protein, peptide, and enzyme production. To facilitate the above, we offer PTFE or TITANIUM rotors, as competitors’ stainless steel rotors could be unsuitable for certain target, biologically etc active compounds. Custom CPC rotor chamber id’s and volumes, and numbers available.
Countercurrent (Hydrodynamic CCC) Chromatography

All Quattro Hydrodynamic CCC models share the same planet & sun radii, beta values, speed / “G” Force options. We will now guarantee in writing the scale-up for any given bore, by increase in coil length / volume. In the vast majority of cases predictable scale-up occurs for different bore id’s as well. But rare exceptions occur even when you maintain all key design parameters. Our almost 20 years of experience suggests the more key design parameters you change, more scale-up failures occur, irrespective of constant “G” force. We challenge anyone to dispute this statement. Occasional scale-up failures that we experience are no different to occasional scale-up exceptions that occur in Process HPLC / Flash Chromatography for certain target / matrix / phase combinations

But uniquely to us, we recognise this and give you lower-cost laboratory scale Quattro LabPrepPlus™ units that can be used for full process scale testing at bores up to 30+ mm. No competitor gives you lab-scale units to test process-scale bore id’s etc.
Do you believe competitors’ suggestions based on very limited Arizona / HEMWat / GUESS mixture solvent / target choices, that their instrument designs, with mini-units ranging from cotton reel sized bobbins rotating at ~2000 rpm, will behave chromatographically the same as maxi-units which you could stand inside rotating at ~800 rpm, simply because “G” Force is the same at 240G, for all target / matrix / biphasic solvent systems? No? Nor do we. We also believe HEMWat has limited applications, excepting restricted polarity pharmaceuticals, they misleading show. They say 90+% their preparations use HEMWat. We say HEMWat useless for most proteins, many peptides, many enzymes, very many natural products / synthetic mixtures. Your views?

Our genuine, experimentation proven knowledge is based on our almost 20 years of CCC / HSCCC / HPCCC / CPC / HPCPC / HPL-LC experience. Please ask competitors, to back their potentially misleading claims by guaranteeing to you their scale-up for all targets / matrices / biphasic systems in writing. What happens when you buy a competitors’ £400000+ / 18+ litre / 10 mm id bore process unit and scale up fails? Would it be cost-effective to optimise a method on such an expensive unit?.

YOUR SAFETY IS OUR MAJOR CONCERN. Now you have seen the video, we imagine you understand why, given our concern for your safety, we were first to use total containment 10 mm thick casework, with massively strong hinges and door inter-lock bar, with options of bench lock-down, automated switch off etc. Plus why we were first, and to date, only manufacturer with one-pass airflow in rotor chamber.
