Degassing Needs for IVD samples
Degassing Needs for Samples & Reagents Inside of an IVD and Molecular Diagnostic Instrument
- Precise dosing along with minimizing dead volume is key for accurate results in a diagnostic instrument.
- Dissolved gases in liquids represent a problem in diagnostic instruments, pressure and/or temperature changes will result in air bubble formation
- Air bubbles affect the precision, accuracy, and performance of the diagnostics instruments
- Degassing below air saturation level is highly recommended, reducing the possibility of bubble formation
- Separel® degassing membranes are essential and reliable products for degassing well below air saturation in any liquid, and/or eliminating air bubble formation
Product Outline:
- In line and reliable degassing unit
- Low-pressure drop (Liquid side)
- Wide product portfolio, accommodating any specific Diagnostic instrument volume sample size
- Excellent chemical resistance and liquid compatibility
- Instantaneous bubble and dissolved gas removal when applying vacuum
- Quality product (Directive EU 2015/863)
How Separel® works?
- Thousands of air permeable hollow fiber membranes are potted and encapsulated into a polypropylene housing
- Liquid flows on the shell side of the membrane contactor while the vacuum is applied on the lumen side
- While the liquid is impermeable to the dense membrane, gases permeate to the lumen side (under vacuum) and are expelled to the outside by the vacuum pump
- The driving force behind moving gases out of liquid is a concentration gradient between dissolved gases in liquid and gas concentration in the lumen side
- Deeper the vacuum applied to the lumen side, the greater is the gas removal
- Only air passes through the membrane to the vacuum side
