Enhancing SPR instrument performance

Biotech Fluidics AB reports that it is supplying key microfluidic and degassing components to BioNavis Oy (Tampere, Finland) for its range of Multi-Parametric Surface Plasmon Resonance (MP-SPR) instruments.

Surface Plasmon Resonance is the ‘go to’ technique for the measurement of molecular interactions in fluidics including serum, saliva, and organic solvents. SPR technology beneficially allows evaluation of affinity and kinetics of molecular binding reactions without the burdens of labelling as the technique is label-free.
The BioNavis Navi™ range of advanced MP-SPR instruments provide superior features and performance enabling both studies of surface interactions as well as nanolayer characterization. Navi MP-SPR instruments are helping scientists with antibody characterization through drug uptake routes, controlled drug release strategies, small molecule measurements, nanoparticle targeting up to drug internalization by living cells.

Jussi Tuppurainen, Technical Director of BioNavis commented “The key part of our MP-SPR fluidics systems are IDEX port selection valves supplied by Biotech Fluidics. These high-quality valves contribute to precise handling of samples, allowing researchers to control the timing, volume, and flow rate of injected liquids. This precision is vital for achieving reproducible results and minimizing variations in sample concentration. Additionally, the Degasser system supplied by Biotech Fluidics helps maintain sample integrity by preventing the introduction of air bubbles, which can disrupt measurements. Careful fluidic design and efficient degassing techniques eliminate bubbles and preserve the stability of the sample, ensuring reliable data”.

In conclusion – Jussi Tuppurainen said “BioNavis has been a satisfied customer of Biotech Fluidics for many years. We highly recommend them not only for their top-quality products, but also because of the consistently professional and friendly customer service they provide.”

The toughest degasser

Biotech Fluidics has recently launched a new model of inline degassers, designed for full compatibility with the toughest solvents. We named it DEGASi® HFIP since it can withstand the highly aggressive solvent hexafluoro isopropanol (HFIP) that is used in liquid chromatography separations of certain polymers and peptides that are difficult to dissolve otherwise. The DEGASi® HFIP inline degasser is compatible with a range of volatile and aggressive solvents, including hexafluoro isopropanol and silanes, but can certainly also manage all other solvents used for gel permeation chromatography (GPC) and size exclusion chromatography (SEC).

Available with two different degassing chambers for analytical and semi-preparative applications, the DEGASi® HFIP can handle flow rates up to 3 and 6 mL/min, respectively. This inline degasser also comes with the new integration feature, meaning that it provides an output signal corresponding to the internal vacuum level (5 mV/mmHg), thus enabling continuous direct monitoring by instrument assemblies and software.

For more information about the new DEGASi® HFIP model of inline degassers, or to discuss the selection of degasser for your application, please contact Biotech Fluidics.

Degassers for your ÄKTA system

DEGASi(R) Prep Äkta

Equipment for preparative purification of tagged and untagged proteins, including the ÄKTA series of liquid chromatography systems from Cytiva Life Sciences, are frequently used in settings ranging from scientific research laboratories to production plants. With these systems, it is possible to perform a variety of chromatographic separation modes including affinity, size exclusion, gel filtration, hydrophobic interaction, reversed phase, and ion exchange. However, in all modes and setups, the formation of bubbles may hamper the reproducibility of purification results and thus limit the overall productivity.

Bubbles form because of high levels of dissolved gases in the employed buffers and solvents. The multiple pressure drops occurring within the liquid flow path through a chromatography system (injector valves, separation column, detector cell, etc.), may initiate bubble formation, especially if any segment also has a higher temperature compared to the eluent bottle. Traditional ways of removing dissolved gases have been to treat the buffers, eluents and mobile phases in ultrasonic baths, but this is both labour intensive and rather inefficient, and risk changing the solution temperature, or may even accelerate degradation of sensitive components. The most efficient and user-friendly way to remove bubbles and dissolved gases in liquid chromatography is by using inline vacuum degassers.

The DEGASi® range of inline vacuum degassers from Biotech Fluidics can be fitted to any brand of liquid chromatography instruments to solve all your troubles with bubbles. The DEGASi® PREP stand-alone degasser is designed for flow rates up to about 20 ml/min per channel and thus suitable for most of the laboratory protein purification chromatography systems including ÄKTA start, ÄKTA go, ÄKTA pure 25 and ÄKTA avant 25, plus discontinued legacy systems such as ÄKTAprime plus, ÄKTAxpress ÄKTA Purifyer and ÄKTA FPLC (some these models were built by GE Healthcare or Amersham Pharmacia Biotech). Several alternative DEGASi® degasser designs are available for chromatography systems with higher or lower flow rate specifications.

Please contact Biotech Fluidics for any questions or concerns regarding what degasser best would suit your needs in terms of flow rates and solvent compatibility.

Tubing kits for dissolution testing

Did you know that Biotech Fluidics custom manufacture tubing kits for dissolution testing equipment and for other purposes?

In pharmaceutical dissolution testing, the solution into which the medication is gradually dissolved, is sampled repeatedly over a certain time period at standardised conditions, to determine the rate of release of an active ingredient. Instruments for these tests are typically designed to perform several parallel experiments in separate vessels. Although sampling could be performed manually, automatic sampling and analysis allow for considerably increased throughput. Automatic sampling typically requires multiple transfer lines to be connected to each vessel for sample withdrawal. This may quickly build up to handling many different sorts of tubing and fitting components to stock for a certain system. Purchasing pre-made tubing kits from Biotech Fluidics can help you simply the setup and execution of these test.

Our long experience in inert and chemically resistant tubing and first-class fittings for a wide variety of requirements, combined with a high-quality assembly line with skilled staff, makes Biotech Fluidics your perfect partner for any tubing kit manufacturing. Tubing kits can be adapted to fit any brand dissolution instrument on the market, including for example Agilent, Bioevopeak, Distek, Electrolab, Erweka, Hanson, Logan, Pharmtest, Sotax, Teledyne, Toron, and certainly also to other types of instruments. Contact Biotech Fluidics to discuss your specific requirements.

Integrate your degasser

DEGASi Integration

Biotech Fluidics has recently launched a new series of DEGASi® inline degassers, designed for integration into analytical or production instrument assemblies. The new degassers are featured with an electronic validation output signal that corresponds to the level of vacuum within the degasser (5 mV/mmHg). This quality allows your instrument software to continuously monitor the degasser performance and present that to the user. If the vacuum level would not meet the set requirements, this feature enables providing the user with adequate warnings or even prevent certain instrument events. This ability to integrate monitoring of your degasser performance is in line with recent regulatory demands regarding instrument performance qualification and is for example aligning with the United States Pharmacopoeia (USP) general chapter 1058.

For more information about this new series of DEGASi® Integration degassers with validation output, or to discuss the selection of degasser for your application, please contact Biotech Fluidics.
