Four Hole Round Ceramic Tube Insulators

Four Hole Ceramic Tube Insulataor

The following four hole alumina ceramic tube type insulators are available in six inch lengths. The tubes are constructed of a pure 99% alumina ceramic that has superior gas and vacuum tightness and excellent insulating properties even at elevated temperatures. They are recommended for use in mass spectrometers and other vacuum systems as feed through lines, thermocouple insulators, and in other applications requiring electrical and thermal insulators. Other Styles are also available - one hole, two hole and solid rods.

The following ceramic tubes are supplied in 6 inch lengths. Unless otherwise noted they can also be supplied in longer lengths (up to 24 inches long). We can also custom cut shorter lengths to your specifications. Contact Us with your specific requirements.

Other sizes available on request

Tolerances on all diameters are ±0.005"

28 Aug 2013: Nanoliter Dispensing Devices can be used to place media on the MALDI plates for MALDI/TOF instruments, but the most exciting ability of this device is to collimate droplets directly into the ion source like electrospray (ESI), the unique concept being that nearly 100% of the droplets go directly into the source versus <1% from ESI, giving a huge increase in sensitivity. We believe this could be the next big advance in LC/MS sources. [NEW]
