Glass Capillary Array

Enabling the vision of tomorrow through massively parallel analysis.

Incom’s GCAs are dense arrays of flow-through glass capillaries with large cross-sectional areas and unlimited length to diameter ratio. Currently manufactured with internal diameter pores as small as 5um, these arrays are produced with a fire polished smooth ID and are chemically resistant. The capillaries can be made in either a clear format or black, crosstalk-reducing format. Incom currently has the ability to manufacture capillary boules as large as 230mm x 230mm x 400mm (L x W x D), which can be formed to any specified dimensions. Their process is scalable and fully customizable to meet your individual requirements.
