No troubles with bubbles


Degassers improve fluidic instrument precision and reliability by removing dissolved gases from fluids before they outgas and form problem causing bubbles. Three main types of bubble removing products are available:

  • Teflon AF based degassers offer the widest range of chemical compatibility and are used to eliminate retention shifts and baseline fluctuations.
  • Silicone based degassers offer the highest flow rate capabilities for water based systems such as diagnostic and life science instrumentation to improve dispense accuracy and reliability.
  • Poridex based products provide rapid bubble remove for locations where bubble introduction cannot be avoided.

  • Degassing process

  • Degassing chamber

    Dissolved gases are actively removed from a flowing liquid stream by vacuum via the IDEX Health & Science AF® membrane.

Degassing – How it works

Dissolved gasses in a fluidic system can often cause troubles. When the pressure or the temperature changes, the dissolved gasses can form bubbles which affect the accuracy, precision and performance of your equipment. On-line degassing is a very efficient way of removing dissolved gasses from the liquid and preventing bubble formation.

Why Degas Your Mobile Phase?

Dissolved air in HPLC mobile phases can result in flow rate instability and baseline disturbance.
Flow rate instability: Non-degassed mobile phase can outgas in the pump head, causing bubbles to be formed and trapped inside the head or check valves. These bubbles can cause flow disturbances and pressure fluctuations, resulting in flow rate instability.
Baseline disturbance: As the mobile phase passes through the column, it experiences a large pressure drop. Non-degassed mobile phase can outgas due to this pressure differential, causing air bubbles to form. Air bubbles passing through or lodging in the
flow cell cause detection disturbances, exhibited as baseline noise.

No Troubles with Bubbles

Biotech AB is specialized in degassing of liquids. With Systec components you can be sure to get degassers with the latest cutting edge technology. Except for our unique range of DEGASi® Standalone degassers, Biotech offers custom made degassing modules to fit your need. Biotech supplies degassing modules to some of the world’s largest instrument manufacturers.


In many low pressure systems, such as diagnostic instruments, bubbles in the fluid stream can cause false detection readings and dispense anomalies. For these systems, the Systec Active Debubbler captures and removes bubbles before they can affect the instrument or the results. Unlike passive bubble traps where bubble removal is dependent on backpressure, the Active Debubbler can be installed before or after a pump and provides consistent debubbling regardless of the system conditions.

Debubbling – How it works

Dissolved gases and bubbles in system liquids cause dispense volume anomalies in many instruments, negatively affecting both dispense precision and analytical accuracy. Now you have a choice of components for actively removing bubbles with or without also removing dissolved system gases. Online Vacuum Degassing offers operating convenience, high efficiency and low operating costs compared to other common degassing technologies.

Why Debubbling?

In medical analyzers, bubbles interfere with critical volumetric reagent dispenses and cause sample failures, wasting time and money. Because bubbles adhere to nearly every part of a dispensing system, high velocity or induced turbulent flow is often used to displace and discharge bubbles from the flow stream and into a waste area. These alternative processes waste reagents and are time consuming, unpredictable, and may additionally require designing the system to recognize bubbles are present.

No troubles with Bubbles

Biotech AB proudly presents a DEBUBBLER for removal of bubbles in liquids. Improve the precision and accuracy in your instrumentation with our new line of debubblers. The new debubbler can be used in every liquid transferring system where bubbles may occur; Dispensing, DNA-sequencing etc. Custom designed modules upon request. We offer total systems responsibility in the field of degassing and debubbling.

    Level Sensor

    A smart way to avoid overfilling the waste bottle.

    How it works

    Light sent down into the glass rod is reflected back as long as the liquid surface level is below the glass rod.As soon as the liquid level reaches the glass rod the light is scattered away from the glass rod and the sensor detects this and gives an output. The level sensor is normally mounted on a bottle cap (GL45). It consists of a ground glass rod, and electronics for detecting fluid on the rod end. The level sensor is powered by 5VDC and the output is a TTL. When the liquid level is below the glass rod the output is high (+5 VDC), and when the liquid reaches the glass rod the output is low (0 VDC). A visual and acoustic alarm is built-in to the level sensor which signals light and sound through a LED and a buzzer when the
    liquid reaches the glass rod.

    Introducing the all new DEGASi line.

    Biotech is pleased to announce the launch of the Biotech DEGASi, a new series of degassing systems. The degassers can be employed in all type of applications where gasses dissolved in the operating liquid may interfere with the use of the system. Degassing is an absolute requirement to get optimal performance out of  your analytical instrumentation or chromatography system!

    The Biotech DEGASi line is easy to use and provides reliable continuous operation for many years. The extremely low internal volume of the Systec AF™ tubing used in the degasser provides for quick equilibration and very short startup times, compared to the use of a degasser which uses PTFE® degassing channels with the same degassing efficiency. The product range includes six different degassers where you select a model depending on the flow rate and what type of solvent used.




    PEEK™-Lined Stainless Steel Tubing




    Biotech AB produly announces the new PEEK Lined Stainless Steel (PLS) Tubing from IDEX Health and Science, for biocompatible UHPLC applications. The tubing combines the strength of industry-standard 316 Stainless Steel with the chemical inertness of PEEK polymer to enable more efficient bio-separations at pressures up to 15,000 psi (1,034 bar).

    Wide Assortment of ID:s Available

    At the heart of PLS Tubing is specially-extruded Upchurch Scientific® PEEK tubing in a wide assortment of inner diameters, ranging from 25 μm ID to 254 μm ID.

    Designed to Work with VHP Fittings.

    PLS Tubing achieves its maximum performance of 15,000 psi (1,034 bar) when used with Upchurch Scientific VHP Fittings. The standard configuration of this tubing automatically pairs a length of tubing with two VHP-325 fittings, which allow repeat connections at UHPLC pressures. (PLS Tubing is also available without fittings to allow the tubing to be paired with different polymer-based fittings; however, the use of other fittings may reduce the overall performance capabilities of PLS Tubing. Please contact us for more information and guidelines on proper use of the tubing.

    Available in a Variety of Lengths

    To accommodate the various connections that are required in the “high pressure” zone of today’s UHPLC systems, PLS Tubing will be available in a number of “off-the-shelf” lengths. (Custom lengths of PLS Tubing are also available, contact us for more information.)

    Strong Yet Flexible

    The unique design features of PLS Tubing allow it to be bent into shapes that may be required by the system equipment, including angled bends and even sample loops for the injection valve, all with no loss of performance. Even in a bent shape, the PEEK lining maintains its integrity along the entire length.
