Line Selection Options
- Connectors
Most systems use a male/male luer-lock configuration for connecting the line to the anesthesia system and monitor. Anesthesia circuits use a female luer lock (on the wye, elbow or filter) which requires a male luer lock fitting on the gas line. The other end of the line depends on the manufacturer of the monitor, but many require a male fitting as well. The connector specification is not dependent on other accessories (Nafion ® tubing, filters) which may be included with the lines.
- Length
The length is dependent on the distance from the point of attachment (anesthesia circuit) to the monitor. Most lines are specified as 10 feet long, although shorter lengths are available.
- Tubing Materials
CO2 Sampling lines are normally manufactured from PVC. If the monitoring of anesthetic gases are needed, a co-extruded PE/PVC material must be used and is available on Zefon's lines of Anesthetic gas sampling lines.
- Inner Diameter (ID) Size
The ID of the tube is critical to the accuracy of the monitor. The correct ID to use is specified by the manufacturer of the monitor. Sizes of .050" or .060" are common and are stocked by Zefon.
- Nafion® Dryer Attachments
Many C0˛ monitoring systems require filtration of the air sample and drying of the air sample. Moisture from the air sample interferes with some methods of C0˛ analysis, and moisture can also destroy some of the detectors. Nafion® dryer tubing has the unique property of removing moisture from the air sample which is passing through the gas line, without affecting the gas concentration. Most monitor manufacturers will specify whether to use Nafion® or not.
- Filter Attachments
Filters which are included with the gas sampling line serve two functions. Because the filter absorbs water, moisture removal is attained. The filters have a pore size of 5.0µ and effectively prevents particulates from entering C0˛ detectors. Some systems will call for both a filter and Nafion ® dryer tube.

Attachments may be preinstalled on any line. To order, select the option you want and adjust the product number to reflect the option. To do this, simply replace the last digit of the product number. Example: To add option #3 to a ZML-9520, change the number to ZML-9523.
Option #1 - Add a 5.0um filter
Option #3 - Add a 12" Nafion® dryer segment
Option #6 - Add both a 5.0um filter and a 12" Nafion® dryer segment
