Enhanced oil recovery (EOR) setup - high pressure (no pumps included)
This setup contains a chip holder, chips for enhanced oil recovery (EOR) and tubing. The only thing left for you to do is to select the EOR-chip of your choice: with a uniform, random or physical rock structure. These microfluidic chips can be used in enhanced oil recovery research, reservoir engineering or environmental research. They are used to verify simulation models of rock-pore structures in the EOR field.

Alignment can be done on positions 2,7 (or 4,9).
There are some things to consider: The PEEK connectors are modified versions of a standard connector. We add some additional thread to the connectors.
The thread length should be ~6-7mm. Please check if the thread link is correct as first. Please assemble according to this manual: https://store.micronit.com/mpattachment/file/download/id/15/ (page 10) The fitting should be tightened on a special hole position at first assembly. This is in the top left corner of the holder. This will assure sufficient force can be applied to compress the fitting without damaging a real chip. Fittings are limited in amount of use. Key importance is that they are clean and free of particle. Salt residues will cause leakage. If issues occur it’s important to use clean fittings. It might be possible that some small re-tightening is required during slow buildup of pressure. Especially at elevated temperatures some relaxation might occur. Please always remove pressure before additional tightening.
The objective working distance is a critical parameter for selection of an objective. Most default objectives are indented for a #1.5 cover slip which is only 170µm thick, where the thickness below channel is mostly in the range of 400-900µm.
Those objectives with longer working distance are often called non-coverglass objectives.
Where possible we would recommend to work dry. In most cases it should be possible to use the channel edge or other well defined point as reference for manual size corrections, this would reduce the need for corrections by the objective.
Large roughness for structures in glass chips is typical observed for structures manufactured by use of laser assisted manufacturing techniques or abrasion-based techniques like powder blasting. Almost all catalogue products from Micronit are manufactured using wet etching to create full transparent channels without substantial roughness.
