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
