1 Scope
This Technical Report gives guidance regarding the selection, specification, installation and use of capture
devices with articulated extract arm (abbreviated: AEAs) in laboratories. The informative material provided
includes the general concept of AEAs, the variety of sub-types available, system installation issues,
performance metrics and operational factors such as use, maintenance and training.
2 General description
Increasingly, capture devices with extract arm (known by a variety of names, e.g. “elephant trunks”, “snorkels”,
“flexible exhausts” etc.) have been installed in laboratories mainly for the purpose of evacuating contaminants
at source. They are used in low-hazard situations such as reduction of heat emitted by lab devices or capture
of emissions, e.g. from HPLC equipment or in similar applications.
The capture performance of AEAs is largely dependent of the (spatial) relationship between the source of the
gas, fume, vapour or dust requiring capture and the inlet hood (capture device) of an AEA. Capture devices
with extract arms are for that reason only useful for example for very small pollution sources or when the
pollution source is too large to reasonably be enclosed and has distinct points where the pollution might occur
like a HPLC. There are today no available universal, readily-applied and normalised test methodologies for
AEA's, although smoke is useful in visualising flows. For this reason care shall be taken in the selection,
installation, and, critically, in-use arrangement of AEAs (as described in Clause 6). Some information can be
found in VDI 2262 Part 4 (see Bibliography, [1]).
AEAs are available in a number of formats, a selection of which is illustrated in the diagrams that follow.

The design shown in Figure 6 can also be used with high level exhaust systems, in which case the flexible
duct merely hangs from ceiling level. The examples shown above relate to the most common approaches of
mounting from above (high level) or bench-mounting. Further alternatives include sidewall mounting a
