Valco/VICI-CompatibleStainless Steel SampleLoops
Valco-Compatible Stainless Steel Loops are manufactured by IDEX
Health & Science. These loops are designed for use with Valco valve
models CW6 and EC6W. Each loop has burr-free, polished ends and
is passivated and flushed with reagent-grade methanol to ensure
cleanliness.
Loops made with 1/16” OD tubing come complete with F-287
SealTight
™
Fittings, which are pressure rated to 9,000 psi (620 bar)
1
.
The fttings and adapters that accompany the 1/8” OD sample loops
are rated to 1,000 psi (69 bar)
1
. Volumes are stated at ±10%, with
exact calibration services available. Each sample loop we calibrate is
documented and supplied with a calibration certifcate.

Sample Loops
Flexible PEEK sample loops are alternatives to stainless steel loops.
PEEK loop ends are provided with clean, straight cuts for easy valve
installation.
PEEK polymer is inert to almost al l organic solvents and is
biocompatible, giving PEEK loops added versatility. Natural PEEK is
used for these sample loops. Like metal loops, the size designations
of PEEK loops are nominal. The actual volumes can differ from the
theoretical designations because of the ±0.05 mm (0.002”) tolerance
of the tubing bore. Accuracy of large PEEK loops (0.8mm, 0.030” bore)
is about ±14%, intermediate loops (0.5 mm, 0.020”) ±21%, and small
loops (0.2 mm, 0.007”) ±65%.
PEEK loops are also supplied with unswaged RheFlex fttings but do
not require the same swaging precaution. The fttings can reposition
along the loop tubing when the ftting reinserts in the ports for correct
loop installation.
Please Note: Several of our PEEK Sample Loops can also be used with
Valco/VICI
®
sample injectors. Please refer to the product lising on this
page to aid selection.

Application Note
PEEK Physical Strength Characteristics
Although PEEK material is compatible with virtually all solvents, there are
many factors that affect burst pressure of PEEK tubing. Factors such as
increases in inner diameter, temperature, exposure time, and concentration
of organic solvents affect the degradation of PEEK. Other solvents such
a THF, methylene chloride and DMSO cause PEEK tubing to swell while
concentrated nitric acid and sulfuric acid weaken the tubing.

These pressure ratings refect the
performance of the fttings, not the
port or valve in which they are used.
