CAPILLARY TUBING AND CAP-LINK TM CONNECTORS

FUSED SILICA CAPILLARY TUBING


Polyimide-clad fused silica tubing is useful as guard columns, retention gaps and transfer lines. Specify the lengths you require when ordering. Untreated or deactivated surfaces are available in all of the standard I.D.'s.

(Prices are per meter)
I.D. Untreated Deactivated* Cat. #**
0.10mm $4.50 $9.00 FST-100
0.18mm $4.50 $9.00 FST-180
0.25mm $4.50 $9.00 FST-250
0.32mm $5.00 $10.00 FST-320
0.53mm $6.00 $12.00 FST-530
** Add "-D" to the catalog numbers for a deactivated surface.
* Minimum order for deactivated tubing is 5 meters.

ELECTROFORMED NICKEL

Highly inert electroformed nickel tubing is ideal for transfer lines where durability is required. The electroformed nickel tubing exhibits a highly inert inner surface which is extremely smooth (<1 microinch). It is very flexible, can be soldered or welded, and can be cut with all common methods. All electroformed nickel tubing is solvent washed, steam cleaned and capped for a superior inner surface. Lengths are custom cut to your specifications. The tube ends are cut flat and electropolished to remove burrs. Add $1.50 per length to the prices below for the cutting and polishing process.

(Prices are per foot)
I.D./O.D. Untreated Cat. #
0.50mm x 1/ 32" O.D. $5.00 EFN-500
1.00mm x 1/ 16" O.D. $9.00 EFN-1000

ULTRA-ALLOY DEACTIVATED TUBING

As an alternative to the tubing listed above, the tubing used to produce the line of Ultra-Alloy capillary columns is also available for guard columns and transfer lines.

#UAT-5-D 5M. x 0.25mm I.D. $180.00
#UAT-5V-D 5M. x 0.50mm I.D. $180.00

CAP-LINKTM UNIVERSAL COLUMN CONNECTORS

Cap-Linkstm allow for the fast and easy linking
of all common fused silica tube diameters.

 

  • Connect guard columns,
    retention gaps, transfer lines
    and different size columns
  • Repair broken columns
  • Extra-long and uniform taper
    for excellent sealing properties
  • One size fits all common
    fused silica tube O.D.'s
    		•
    #999-LINK-5 Cap-Link (pkg. of 5) $25.00
    #999-LINK-25 Cap-Link (pkg. of 25) $125.00

     

    CAP-LINKTM Y-SPLITTERS

    With the same advantages as the standard Cap-Link, you can also...

    • Split carrier gas flow to two columns
    • Split column outlet flow to two detectors
    #999-Y-LINK Cap-Link Y-Splitter $55.00
    #999-Y-LINK-3 Cap-Link Y-Splitter (pkg. of 3) $140.00

     

    POLYIMIDE SEALING RESIN

    Permanently seal capillary columns to the Cap-Link Connectors. The Sealing Resin eliminates loss of the seal and resulting leaks. Also useful as a high temperature glue. Can be used in continuous temperature applications of up to 420șC.

    #999-LINK-4002 Polyimide Sealing Resin (10 grams) $20.00
