Dual-Layer Color-Coded PEEK® tubing
Sample contamination by color pigments is not a concern with this tubing, since the pigmented
layer surrounds a separate inner layer of natural PEEK. 1/16" OD tubing is available in standard IDs and
colors, and in OEM quantities with any color or ID specified, from .002" on up. Call us about any custom tubing
needs you have.

Dynacalibrator® Model 150
Dynacalibrator calibration gas generators are used to verify the accuracy of analytical data
from air pollution
monitoring, industrial hygiene surveys, odor surveys, and other instruments measuring
gas concentrations. Our new model controls the chamber temperature to ±0.01°C,
measures only 6" wide x 15" deep x 7" high, and weighs just 10.5 pounds.
For more information, email VICI Metronics
or call (877) 737-1887.

No twist one piece fittings
The no twist design has a separate ferrule that snaps into the nut, so it's attached but still
free to avoid rotation during tightening. In other one-piece designs, the ferrule rotates against the
fitting detail, creating particulates.

email us
or call (800) 367-8424.

Reduced breakdown injection port liners
DDT and endrin are easily degraded in the injection port. In EPA methods
SW-846, if degradation of either DDT or endrin exceeds 20% or the combined
breakdown of DDT and endrin is greater than 20%, corrective action must
be taken before proceeding with calibration. Our first users report that
the RBL liner is still exhibiting less than 2% endrin breakdown after
two months of use!
For more information,
email us
or call (888) 217-7199.
