Enhanced Oil Recovery (EOR) chip - Physical Rock network

1) Flush an alkaline solution through the channels, like 1 M sodium hydroxide in water. 2) A water bath with ultrasonic agitation can be used to remove particulated matters, keep energy levels initially low to prevent potential damages. 3) Glass microchips can be heated (e.g. 400°C) causing any organic material on the glass surface to degrade. Try to use lower temperatures first because burning the content could make it stick. 4) Concentrated sulfuric acid works well to dissolve organic material, such as fibres, that are difficult to remove with alkaline solutions.

The EOR chip itself is manufactured from glass and can easily withstand up to 300⁰C. The chips are supplied in a black fluidic cartridge however, this cartridge can withstand up to 80⁰C.No sealant is used, the two layers of glass are fusion bonded together.The chip can withstand easily up to 100 bar. The external interfacing is more critical however. Our Fluidic Connect holder offers the largest pressure, up to 80 bars (maybe less at elevated temperatures). Please note that it might be helpful to practice a little with the Fluidic Connect holder first. You need to get the feeling to apply not too much force, which might break the chip, but enough to obtain sufficient sealing. It might be necessary to tighten a bit more when pressure and temperature are increased. Please remove the pressure before additional tightening.

The fluidic ports are on positions 3,8Alignment can be done on positions 2,7 (or 4,9).

You need a combination of items supplied by Elveflow and Micronit. Please take a look at the full answer for more details.

The objective working distance is a critical parameter for selection of an objective. See "Read More" for recommendations.

Wet etched structures are extremely smooth and have a roughness in Angstrom range. The structures are fully optical transparent.

Micronit offers a range of chip holders designed to ensure reliable and convenient interfacing between your chip and fluidic tubing. See "Read More"for additional information and links.
