Flow cell with a serpentine channel. Details depend on selected configuration.

Application possibilities

This product is designed for observation purposes and offers sublime optical performance in combination with microscopy. This allows high resolution imaging. A regular flow cell offers a limited observation length, using a serpentine shaped channel substantial channel length is created. This allow much longer observation time without reducing the speed to much.  

Research examples can be for instance:

  • Observation of cell interaction with media, like for instance exposure to toxins or active substances.
  • Research on interaction between liquids
  • Observation of a reaction
  • Use as collection reservoir, for instance combined with a PCR reactions

Unique selling point

  • The channels doesn’t have any substantial roughness and are fully optical transparent due to the etching process used.
  • Glass offers sublime optical transparency and low autofluorescence.
  • When fluorescent markers are used we have also a D263-Bio version available for even lower autofluorescence in some critical wave length areas.
  • Thin bottom version are compatible with a #1 (11003694) or #1.5 (11003040) coverslip
  • Different size available for a optimal match with cell size used or optimal liquid volume.

Customer Questions
Can this flow cell be customized?
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.
{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.
When should I use the metal strips (spacers) as provided with the Fluidic Connect Pro holder?
When should I use the spacers? The metal strips are used for thin bottom chips and are also part of the holder for resealable flow cell's.

The spacers are placed beneath the top insert, as shown in the picture below. What should I do when I don't have spacers available?
Just contact us to request new spacers.
What is the roughness of the etched structures?
Wet etched structures are extremely smooth and have a roughness in Angstrom range. The structures are fully optical transparent. 
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.
