PENN-CENTURY AIR PUMP – MODEL AP-1
**NOTE: The Air Pump Model AP-1 has been discontinued due to changes from our suppliers. We are developing a new, hand-held Air
Pump Model AP-2 for rapid applications of precise volumes of air for use with our Dry Powder Insufflator™ Model DP-4 or Mode DP-4M. The
new Air Pump will be available after development and testing to assure t meets our quality standards. Contact us for updates.
Penn-Century Air Pump – Model AP-1 is designed to “insufflate” or blow air through the powder sample of
the Model DP-4 or DP-4M. The pump has a spring-loaded thumb button that automatically returns, instead of a
plunger that must be pulled up and pushed in each time. It permits the user to rapidly generate single pulses or
puffs of air at a specific volume, each time the thumb button is depressed. The air setting of device is adjustable
to administer pulses of air from 0 - 5 ml – depending on the lung capacity or tidal volume of the animal to be use.
It may be used with any Model DP-4 and is required for use with the Model DP-4M. , Because the thumb button
of the Air Pump returns automatically and delivers
the same exact air volume pulse each time, it
minimizes the undesirable hand motion that occurs
when trying to aerosolize the powder using a
plunger-style air syringe. It also avoids the
necessity of removing tip of the Dry Powder
Insufflator™ from the trachea to locate the correct
air volume setting of a plunger-style air syringe
each time the user wishes to administer more than
one pulse of air. The Air Pump has a larger
diameter piston than a commercial air syringe
provided with the device and is made of plastic
with a rubber seal and a male luer slip tip.
Setting of air volume: As a convenience to the
end user, the device is shipped set to deliver a
volume of air for the animal specified. Typically, the device is set at the customer’s request to air volumes of:
200μl for mouse, 2 ml for rat, or 3 ml for guinea pig. The Air Pump can reset by the user to administer up to 5 ml
using a small hex wrench provided.
100MG SAMPLE CHAMBER EXTENSION – MODEL SC-X
Description: For administration of dose
volumes greater than 5 mg, the 100 mg
Sample Chamber Extension – Model SC-X
can be purchased. This tube press-fits to
the top of the Sample Chamber to provide
a deeper capacity for larger powder
samples. When filled, the Air Intake is
attached to the Sample Chamber Extension.
When administering large volumes, the
user must determine how much emerges
from the Model DP-4 with each pulse of air,
as it may take more air pulses to administer
100% of the dose, particularly when
volumes larger than 5 mg are being
administered.
