Freestyle Workstation


freestyle_allFreestyle Overview

Freestyle is a workstation platform for many automated sample clean-up tasks. Available automated features are Gel Permeation Chromatography (GPC), Solid Phase Extraction (SPE), evaporation and concentrations (EVA), and liquid handling routines.

The basic workstation begins with a liquid handling robot, software and rack space to add components to build the configuration to handle your sample clean-up needs. Add modules to add the functionality you need to simplify sample clean-up.

Automating your sample clean-up eliminates inconsistencies and errors that require expensive re-extraction and re-analysis. The productivity times are significant as the higher value work can be performed while the system works unattended. Your team is made safer with reduced exposure to health and safety issues inherent to repetitive motion and chemical exposures.

  • Fully automated and integrated features
  • Handles multiple different vial/bottles sizes


Freestyle BASE


The base unit includes the liquid handling functionality of an X-Y-Z robot arm, rack the rail to mount bottle racks, valves for up to 6 solvents, fluid handling needle system with wash and sample loops. This is the foundation on which additional modules can be added including: SPE handling, GPC processing and Evaporation functions.





Freestyle SPE


The SPE Module includes an additional robot arm for handling SPE cartridges with an airtight holder seal for positive pressure operations. The two robot arm system is capable of “Hold and Inject” of the SPE cartridge. Software will program the SPE functions of conditioning, loading, washing, drying, eluting. Column drying is capable with Nitrogen or air.

The FREESTYLE SPE instrument combines ease of programming with multiple process options including conditioning, loading, washing, drying, and eluting. With each step comes the ability to optimize for best results.

Addition of the FREESTYLE GPC module enables GPC to SPE processing.

Automated Solid Phase Extractionfreestyle-solid-phase

The new generation of LCTech Systems allows for unique flexibility – all due to new mechanics and software.

The sample preparation systems are designed for the fully automated handling of foods and feeds, environmental samples, and other comparable tasks around the clock.

The FREESTYLE™ SPE automates all processes of solid phase extraction (SPE) – if desired in combination with evaporation and solvent exchange.

The FREESTYLE™ SPE handles any SPE or immunoaffinity column from virtually any manufacturer.

The columns can be placed into the system with or without caps.

Module for EVAporation, with online connection to SPE

The FREESTYLE™ SPE can be easily supplemented with an EVA module to include the automated function of evaporation or concentration features. Your sample can be cleaned up using the SPE module, then concentrated down to any value between 0.5 mL and 5 mL (in increments of 0.1 mL).






Freestyle GPC


The GPC Module enables Gel Permeation Chromatographic sample clean-up with optional column switching valve for multiple columns. The software can program 5 different modes of injection. User defined fractionations of the main run. Add the evaporation module EVA for concentration and solvent exchange.

The FREESTYLE GPC instrument innovates Gel Permeation Chromatography for sample clean-up. Using patented robot handling abilities and innovative user software, multiple GPC tasks are programmed for unattended operations.

Efficient Sample Clean-Up

The FREESTYLE™ GPC automatically cleans up raw extracts and removes interfering matrix components such as: lipids, pigments, sugars or humic acids. The system is universally used for sample clean-up for the analysis of: food, feed, soil and environmental samples.

Gel Permeation Chromatography (GPC) is specified as the clean-up step in many official methods. This robust procedure is still the best solution for difficult matrices such as animal tissues, fatty foods, spices, and sediments.

Flexibility Adds Value

The workstation is designed to integrate hardware and software to offer extraordinary flexibility. The unique glassware rack design enables glass sizes from 1 mL to 1000 mL, along with a variety of shapes from round bottle roto-vap flasks to standard vials. Racks can be heated or cooled as needed.

Liquid handling features include: all classical injection procedures, including sample loop overfill and direct injection. Quantitative transfer to several glasses, flasks and fractionation to different glass types and sizes are also possible.

In-line Evaporation Concentration

Add the FREESTYLE™ EVA module to the workstation to include the automated function of evaporation or concentration features. Your sample can be separated in the GPC module, then concentrated down to any value between 0.5 mL and 5 mL (in increments of 0.1 mL)

The FREESTYLE™ GPC meets the requirements of the following protocols:

  • USEPA SW-846 Method 3640A
  • USFDA, USDA/FSIS CLG-CHC3, EN 1528, EN 12393, L00.0034
  • AOAC 984.21
  • DFG S19 
  • USEPA 8310 
  • AOAC 984.21, 8290 C, 3540 A


Freestyle EVA


The EVA module enables evaporation, concentration, solvent exchange functionality. The sophisticated evaporation chamber has a complex orbital drying action to slowly evaporate highly volatile samples down to 0.5 ml. Nitrogen blow-down can be combined with vacuum for high recoveries while quantitative transfer enables 100% of sample to be injected into the evaporation chamber.

Innovative design of the orbital rotational Evaporation Chamber produces sample results of 0.5 mL to 5 mL

The New Step Into Evaporation

The FREESTYLE™ EVA can concentrate samples of undefined volumes (max. 330 mL) to any end volume between 0.5 mL and 5 mL (in steps of 0.1 mL).

[Freestyle EVAporation]  

For this purpose two evaporation procedures are available:

  • Vacuum with regulated heating
  • Nitrogen blow-down (or air) with or without regulated heating

Both procedures can also be combined in one method – it is only necessary to adapt the software accordingly.

Solvent exchange is also possible (liquid/liquid or evaporation to dryness and taking up a new solvent).

Thus, the user has many different possibilities of:

  • Aliquotation
  • Automated solvent exchange
  • Quantitative transfer

With the FREESTYLETM software, all individual steps of the evaporation process can be controlled in detail.

The result: Following a defined, reproducible procedure the concentrated sample at the desired end volume is ready for further treatment.


Freestyle GPC+SPE+EVA


The FREESTYLE completely configured is a powerful productivity tool for automated unattended sample cleanup tasks. GPC processing can be combined with SPE and evaporation for complex programs. All sample clean-up routines are performed precisely, reproducibly and safely, providing the best quality samples for analysis.

Better analysis quality because the sample clean-up is automated, precise and optimized. The productivity gains are significant.
