Unibloc Bubble Traps
If gas bubbles are present in a closed system, microfluidic experiments can produce inaccurate results. When working with small volumes of liquid, the elimination of bubbles using bubble traps is a key factor for creating accurate and repeatable results in microfluidics.
A bubble trap is either an active or passive device used to remove air bubbles from microfluidic systems. Unibloc combines ultra-clean components and simple design making our bubble traps the standard in the chromatography, pharmaceutical, and biotech industries.

What is a Bubble Trap?
A bubble trap is a device that removes air bubbles from aqueous solutions inline or downstream in a fluidic system. Unfortunately, air bubbles in the fluidic flow can cause significant problems for applications because the bubbles unexpectedly change the intrinsic physical properties of the microfluidic environment. This change can increase the internal pressure abruptly in a fluidic/microfluidic system. It may lead to sudden shear force variations, which change the compliance of the system or even blocks small channels. Bubble traps are instrumental in ensuring a safe performance in any sanitary hydraulic system.
