Our glass concentric nebulizers are available in four styles, all of which have Glass Expansion's unique VitriCone construction:

A: Direct Connection (DC) Nebulizer

The DC nebulizer is our latest design. It has a UniFit sample connector which slides easily over the sample arm and an argon connector configured to connect directly to your ICP. The benefits of the DC nebulizer are:

In addition to these unique benefits, the DC nebulizer shares the following benefits with the U-Series nebulizer:

Part number A14-07-USS2, SeaSpray DC Nebulizer for Agilent 5100

DC versions of the SeaSpray, MicroMist, Conikal, Slurry, DuraMist, OpalMist and VeeSpray nebulizers are available to suit the most common models of ICP-OES and ICP-MS. The glass DC nebulizers use the inert PEEK gas connector, part number 70-803-1096.

The DC nebulizer part number has a prefix specific to each type of gas connector. For example, the prefix "A14-" denotes a connector for the Agilent 5100 ICP-OES, so part number A14-07-USS2 is a SeaSpray nebulizer configured for direct connection to the Agilent 5100.

B: U-Series Glass Concentric Nebulizers

The benefits of the U-Series nebulizer are:

SeaSpray, MicroMist, Conikal and Slurry U-Series nebulizers are available to suit all common models of ICP-OES and ICP-MS. Each U-Series nebulizer is supplied with a UniFit sample connector.

U-Series nebulizers can be identified by the letter 'U' in the part number, e.g. ARG-07-USS2 or ARG-1-UM04.

C: Nebulizer with EzyFit connector

The EzyFit is a sample connector which slides into the nebulizer sample arm. It provides lower dead volume and faster washout times than earlier designs but is not quite as effective as the newer U-Series.

Nebulizer with EzyFit connector

The SeaSpray, MicroMist, Conikal and Slurry nebulizers are available with EzyFit connection. They can be identified by the letter "F" in the part number, eg. AR30-07-FSS2E or AR30-1-FM04E

D: Nebulizer with standard connection

This is the original design and is now very rarely used. It is not supplied with a sample connector and it is not compatible with either the EzyFit or UniFit connectors. The connector must be supplied by the user. This nebulizer design has a larger dead volume and longer washout time compared with the newer designs, so it is not generally recommended.

The EzyLok argon connector

The EzyLok argon connector is used with all glass concentric nebulizers except for the DC nebulizers.


The EzyLok connection is made with our specially formed nebulizer side arm, which allows it to be pushed and locked securely into the popular 'One Touch Fitting' which incorporates a flexible o'ring seal. To disconnect the nebulizer, simply push on the release button located at the top of the fitting.

All ICP Nebulizers are NOT created equal

Only Glass Expansion nebulizers include the unique VitriCone construction.

With some brands of glass concentric nebulizers, the sample channel is constructed from drawn out capillary tubing. The problems with this type of construction are:

All Glass Expansion concentric glass nebulizers use the unique VitriCone construction for the sample channel. With the VitriCone design, the sample channel is constructed from heavy glass capillary which is machined to very high tolerances. The benefits of the VitriCone construction are:
