Labeling Sample Vials
Vials are available with a write-on spot for easy marking. If you choose to make
and apply your own labels, Agilent Technologies, Inc. recommends the
positioning and maximum label thickness shown in Figure 3.
Figure 3 Label specifications
Caution Correct sample vial dimensions are critical for proper tray gripper operation.
Vials and labels that do not meet these specifications may cause sampler errors.
Service calls and repairs found to be due to vials and microvials that do not meet
these specifications are not covered under warranty or the service contract.
Sample Vial Septa
There are 2 types of septa used with crimp caps and screw-on caps, each with
different resealing characteristics and different resistance to solvents.
• One type is natural rubber formulation coated with Teflon on the sample
side. This septa is suitable for samples with a pH range of 4.0 to 7.5. It is less
resistant to solvents after puncture, and is more easily cored than silicone
rubber. Coring may deposit septum pieces in the vial and affect your
chromatograms.
