Short Answer -  No

The standard bare fused silica capillaries offered for capillary electrophoresis (CE) applications are manufactured with a 365 µm outer diameter (OD).

This dimension is widely used across many CE instruments and applications and is the standard offering available from inventory.

Standard CE Capillary Dimensions

MICROSOLV bare fused silica capillaries for CE applications are supplied with:

• 365 µm outer diameter (OD)

• Various internal diameter (ID) options, depending on application requirements

• High-purity fused silica construction

• Compatibility with common CE instrumentation

The 365 µm OD format is the most commonly used configuration for routine capillary electrophoresis workflows.

Are Other Outer Diameters Available?

Alternative capillary outer diameters may be available through custom manufacturing programs.

Custom capillary orders may be appropriate when:

• Instrument requirements differ from standard configurations

• Specialized research applications require unique dimensions

• Method development protocols specify non-standard capillary sizes

• Custom CE system configurations are being utilized

Minimum order quantities and manufacturing requirements typically apply.

Special Order Considerations

Laboratories interested in non-standard capillary dimensions should consult Customer Service regarding:

• Available outer diameters

• Manufacturing feasibility

• Minimum order quantities

• Lead times

• Custom specifications

Custom products may not be stocked and may require additional production planning.
