What Is HPLC Capillary Tubing?
HPLC capillary tubing is the high-pressure stainless steel line that links HPLC modules. Short, correctly sized tubing limits extra-column volume so peaks stay sharp from injector to detector.
uHPLCs / HIPSOUL supplies flexible HPLC stainless steel tubing cut to catalog lengths, with fittings ready for common 1/16" HPLC ports. Related hardware: HPLC fittings, inline filters and guard columns.
How to Choose HPLC Capillary Tubing
Use a simple Find → Match → Select path. Do not change ID or length casually—match the instrument drawing or the line you are replacing.
Step 1
Find the connection
Note OD at the port (1/32" or 1/16"), existing ID, and the measured length between fittings.
Step 2
Match ID and length
0.13 mm for low dead volume; 0.18 mm mid-bore on 1/32"; 0.25 mm when higher flow is required. Keep length as short as the layout allows.
Step 3
Select fittings
Catalog SKUs include two sets of 1/16" connectors and ferrules. Confirm ferrule style for your HPLC brand before install.

Install HPLC Capillary Tubing Cleanly
Cut only if the catalog length is longer than needed. Seat ferrules fully, avoid over-tightening, and keep the line as short as the instrument layout allows.
- Match OD and ID to the ports you are connecting
- Use the supplied 1/16" connectors and ferrules unless the OEM specifies otherwise
- Route without sharp kinks that raise local pressure drop
- Flush new tubing before the first analytical run

HPLC Capillary Tubing FAQ
What is HPLC capillary tubing?
HPLC capillary tubing is the high-pressure stainless steel line that carries mobile phase and sample between HPLC modules—pump, injector, column and detector. Correct OD, ID and length keep dead volume low and peak shape stable.
What HPLC capillary tubing sizes are listed here?
This page lists high-pressure flexible stainless steel capillary tubing in 1/32" and 1/16" outer diameter, with inner diameters of 0.13 mm, 0.18 mm and 0.25 mm. Catalog lengths run from 50 mm to 2000 mm depending on the series. Most SKUs include two sets of 1/16" connectors and ferrules.
How do I choose HPLC tubing ID?
Match ID to flow rate and dead-volume tolerance. 0.13 mm suits low-volume analytical paths. 0.18 mm is a common mid-bore option on 1/32" OD lines. 0.25 mm is used when higher flow or lower back pressure is needed. Confirm the ID already used on the instrument before changing.
Is this HPLC stainless steel tubing pre-fitted?
Listed catalog lines are supplied with two sets of 1/16" connectors and ferrules. 1/32" series items in the sheet also use red protective sleeves at the ends. Specialty lines cover pump-head-to-injector and Agilent column-inlet replacements.
Can HIPSOUL supply OEM HPLC capillary tubing?
Yes. Share OD, ID, length, fitting type and instrument brand. OEM and private-label HPLC stainless steel tubing can be produced against your drawing or a sample.
Request HPLC Capillary Tubing Pricing
Send the OD, ID, length and instrument brand. We will confirm the matching HPLC tubing code—or quote a custom cut—for analytical labs and OEM programs.
