Quartz glass capillary has a series of excellent properties in optics, physics, mechanics, electronics, and more. The accuracy or precision of the inner diameter between different segments or batches of quartz capillary tubes cannot be compared to other material devices.
With the continuous miniaturization of various technologies, quartz glass capillaries will play an increasingly important role. The interface connection between new microfluidic devices and existing constant sample processing platforms is a good example. Another more appropriate example is the sample injection valve for miniaturized capillary liquid chromatography (i.e. nanoliquid chromatography), the connection tube between chromatographic column and detector.
1. Application fields of quartz capillary tubes
Quartz glass capillaries can be widely used in the fiber optic and communication industries, such as PLC splitter access terminals, fiber optic splitters, WDM wavelength division multiplexers, fiber optic sensors, fiber optic PIGTAIL, fiber optic array substrates, single fiber capillaries, single fiber Pigtail, double fiber Pigtail, double hole Pigtail, square Pigtail, eccentric Pigtail matching glass capillaries, etc; In addition, quartz glass capillaries are also a key component and essential material for gas chromatography, DNA sequencing and fragment analysis genomics, proteomics, Capillary electrophoresis instrument, capillary liquid chromatography instrument, and microfluidic instruments in the electronics, medical, and optical industries.
2. Classification of quartz glass capillary tubes
According to the different product design and application characteristics, it can be divided into:
(1) Classified by precision: high precision, medium precision:
(2) Classified by shape: standard tubes, square tubes, conical tubes, D-shaped tubes, irregular tubes (V-shaped, U-shaped quartz capillary tubes), elliptical tubes, hexagonal tubes, etc.
(3) Classified by aperture: round hole tube, double hole tube, porous tube, square hole tube, elliptical hole tube, eccentric tube, V-shaped hole tube, D-shaped hole tube, U-shaped hole tube, etc.
(4) Classified by purpose: quartz glass capillary, quartz glass capillary connector, quartz gas chromatography column, quartz capillary column, fiber array substrate, etc.
