The assembled YDRH
(Figure 1 ) was part
of a closed-loop dynamic flow system that recirculated collection
Milli-Q water solvent by a peristaltic pump (Reglo 2-channel Var-Speed
Analog pump from Cole Parmer, Court Vernon Hills, IL) at 100 mL/min
between the inside surface of the test disposable nitrile glove and
the outside surface of the CPC Solvex powderless unsupported/unlined
nitrile glove (Ansell, Iselin, New Jersey) that protected the YDRH.10 (link),11 (link) The inlet and outlet of the YDRH were connected to the sampling
point by Viton tubing (2.79 mm inner diameter extension and three-stop,
Cole Parmer, Vernon Hill, IL). The hand in exposure situations was
immersed inverted, held by the wrist from a clamp, in limonene contained
in a vacuum desiccator (5-L from Fisher Scientific) within a Precision
Econotherm Laboratory Oven (Fisher Scientific) at 35 °C (Figure 1 ). The hand was powered
as described elsewhere to produce a 1.8 kg clenching force.8 (link),10 (link),11 (link) Thicknesses of the conditioned
and reconditioned gloves after each permeation experiment were measured
with an Electronic Digital Micrometer Model CO-030025 (0–25
mm, 0.001 mm resolution) from Fisher Scientific. Permeation experiments
were performed in triplicate.
