Model 3025A UCPC with Nano DMA
Model 3776 or 3025A with Long DMA
Refer to Figure 3-11 and Figure 3-12 and the following instructions
to connect the plumbing between a Model 3080 Classifier with a
Model 3081 Long DMA and a Model 3776 or 3025A UCPC:
1. Locate the ¼-inch diameter (nominal) flexible tubing (3001903)
from the Classifier accessory kit and cut a length to 25 cm
[10 in.].
2. For the 3776 UCPC, locate the Fitting adapter assembly
(1035992) from the SMPS
™ accessory kit and fit the
3
⁄8-inch end
over the inlet of the UCPC. This step is not needed for the 3776
UCPC because the inlet of the 3776 is ¼-inch.
3. Locate the Flow equalizer assembly (1035989) from the SMPS
™
accessory kit and attach the straight portion of the tee to the
inlet of the 3776 UCPC or the fitting adapter on the 3025A
UCPC.
4. Position the 3776 or 3025A UCPC so that the flexible tubing
connects from the DMA monodisperse aerosol outlet to the tee.
