H-shaped channel for boundary flow experiment - 350 x 150µm

Absolutely! Micronit is a key supplier for flow cells in the Next Generation Sequencing market and can manufacture flow cells competely according to your specific requirements. What can be customized? The channel shape. The channel height and width.For wet etching its important to consider that channel height and minimal channel width are related.<br>{minimal channel width} = 2 * {etch depth} + {initial mask opening, typcial 5-10µm}Larger aspect ratios (relation between channel depth and width) are possible using dry etching. For this, a glass/silicon combination is most common. Choice of material. For instance, fused silica is a good option when UV light is used. Schott D263 bio can be a good alternative for some specific fluorescent labels. Surface flatness. We can provide ultra flat surfaces.

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.

Chips that have Micronit’s standard hydrophobic coating can be cleaned with most organic solvents.
