Section 2
Design and Features
The main purpose of this battery-operated personal sampling
pump is to draw contaminants from an air sample into, onto
or through a sampling media such as 25 and 37mm filter
cassettes, bubble impingers, long-duration color detector
tubes to gauge personnel exposure to gases, vapors, particu-
lates, aerosols, etc. Both the analytical method required for
the contaminant and the types of contaminants sampled
determine the selection of sampling media. Many sampling
methods specify the use of filters for collection. (i.e. Asbes-
tos and Lead). The pore size, filter diameter, and filter
material affect the ability of the sample pump to draw air
through the filter for contaminant collection.
The BUCK-Libra Plus™ Model LP-5 Personal Air Sampler
consists of a pump contained in a Lexan case, exclusive and
proprietary electronic circuit board for flow control, an LCD
display with 2 lines of 16 characters, a single diaphragm
pump mechanism and a rechargeable nickel metal hydride
battery pack.
Features:
▪Flow Compensation for filter plugging and battery voltage
▪Compact, Rugged and quiet
▪No tools required to change flow rates.
▪Battery pack rechargeable while attached or separately
▪Stainless steel belt clip with built-in tripod connector
▪One-hour rechargeable batteries and optional extended run
triple packs
▪High impact Lexan case, antistatic and RFI shielded
▪“Auto-restart” within one minutes of a flow fault
▪Flows up to 4 LPM for special cyclone requirements
▪Dual flow range easily handles filters, impingers, cyclones,
and tubes
▪High backpressure capable for 25mm 0.45 u asbestos filters
▪Built in washable stainless steel 100 micron filter
▪Displays: elapsed time, accumulated volume and flow rate
▪Accuracy +/- 5% of display reading or pump Flow Faults
▪Count down timer up to 40 hours, turns off pump.
▪Key pad lock system
▪One year warranty

A/C Power Supply (continuous sampling)
The Standard Battery Charger for BUCK pumps, will supply
enough power to operate the Libra Plus Pump continuously while
sampling. Simply plug the charger into the battery pack into 120
VAC outlet and turn the pump on to sample.
Interchangeable Batteries
The BUCK-Libra Series incorporates a unique system of inter-
changeable batteries to provide additional flexibility in sampling.
A Triple Pack is available for extended run times. All run times
are tripled from those stated for a single Standard Pack.
Battery Pack
The BUCK-Libra Series Standard Battery Pack consists of four
nickel metal hydride batteries. The batteries are rated at 2150mA
hour capacity. The QuickOne™ and QuickFive™ Battery Chargers
connect to the back of each battery case; by lifting the protective
rubber cover, the charger lead can be easily inserted. A Triple
Battery Pack may be substituted for the standard battery pack to
provide three times as much battery capacity for the Libra Plus.
When a Battery Pack or pump with Battery Pack is connected to a
BUCK QuickOne™ or QuickFive™ Charger, a yellow LED
(CHARGING) will indicate the charging cycle has begun. The
charge cycle takes approximately one hour for the single packs
and 3 hours for the triple packs. When the charging cycle is
completed, a green LED will light (READY) indicating end of cycle.
Individual battery packs may be charged independently of the
pump if required. The pump may be left connected to the charger
in “trickle charge” indefinitely. Battery pack cases are connected
to the pump case bottom with four self-retaining screws.
Caution: Never charge batteries in hazardous areas.

BATTERY CHARGERS and A/C Power Supply
Note: The BUCK QuickOne™ and QuickFive™ Battery
Chargers are designed to charge only the Nickel Metal
Hydride (NiMH) battery packs for the BUCK-Libra Plus
Pumps.
BUCK QuickOne™ and QuickFive™ Battery Chargers Description
The BUCK QuickOne™ and QuickFive™ Chargers are microproc-
essor-controlled battery chargers providing an entirely automatic
battery charging cycle in approximately one hour. The pump bat-
tery pack can be recharged with or without the pump connected.
When inserting the charger lead into the battery pack socket, first
lift up the protective rubber cover. The charger uses a voltage/
temperature detection technique that provides a full recharge.
When plugged in, the Yellow and Green LED light to indicate the
microprocessor is functioning and the charging cycle is in
progress (“Yellow”) and finished or ready (“Green”).
The QuickOne™ and QuickFive™ Chargers will charge a
completely discharged pump battery in one (1) hour. Three (3)
hours for the optional Triple Pack with a fully discharged pack.
After a full charge, a trickle charge cycle (“Green” LED) will begin.
Batteries may be left in trickle charge indefinitely.
The charger is designed to operate from a 100 - 240 VAC. The
charger begins operation automatically when plugged in to an AC
source.
Operation
When plugged in, the “Charging” light will indicate Yellow (ON).
When the green light turns ON and Yellow turns OFF, the batteries
are fully charged.
Standard Charger
The Standard Charger is designed to charge the BUCK PUMP
NiMH battery single pack in 16 hours. The connection is made
through the same charge port on the rear bottom of the battery
pack. The RED LED light on the A/C charger will light. After 16
hours, the pump batteries will be fully recharged for portable
operation. The battery pack can be charged either on or off the
pump. Note: The Standard Charger is not recommended for the
Triple Packs.

LOW FLOW TUBE SAMPLING (5 to 800 cc/min.)
Using the setup as shown above, flows of 5 to 800 cc/min.
may be collected in adsorbent tubes (charcoal, silica gel,
etc.). NOTE: first set up sorbent tube in Tube Holder with
proper tubing before turning pump on.
Low Flow Sampling Procedure:
1. The pump must be in PRESSURE MODE
under Flow Adj. MENU. Arrow the flow
below 800 cc/m. This will place the pump
in Pressure Mode and turn on the pump motor to
operate at a set speed.
2. Using the mini-BUCK Calibrator M1 (0.1 to 300 cc/min.)
or M5 (1 to 6000 cc/min.), measure the flow through the
adsorbent tube as shown above. Use a screw driver to
adjust the flow to the desired rate.
3. Once the sample flow rate has been set, press the SET
and Arrow key to match the measured flow on the
Calibrator. An accuracy flow of ± 5% will be maintained
throughout the sampling day. In Run Mode the flow rate
will be displayed and the accumulating volume will be
accurate.
4. Some new higher flow thermal desorption with higher
backpressure tubes may be used in “Constant Flow”
Mode with the non-adjustable tube holder (P.N. APB
-109032) for flow above 800 cc/min.

Setting the Flow rate
1. Connect sampling filter with a hose to the pump.
2. Turn on the pump by pressing the ON key.
3. Next press the down arrow to the Flow adjust Menu.
4. Press and hold the SET key and
use arrows to adjust flow.
(This clears all previous data).
5. Releasing the SET key will store the flow rate.
6. Press the ON/OFF key to return to Main Display, then
press the up arrow (RUN) to begin sampling.
To clear all sampling data and sample at the previous flow
rate, from the Main Display press the down arrow key twice to
the “Clear Data Menu”. Press and hold the SET key and press
the up key for Yes clear data. Press the ON/OFF key to return
to the Main Display and press up arrow to begin sampling.
Pump calibration Adjustment if needed at point of Flow Set
1. To measure the flow rate have a Calibrator ready and con-
nected to the filter as shown above.
2. From the Main Display down arrow to
the Calibration Mode.
3. Press the SET key and release, pump
begins to flow at preset flow rate from the steps above.
4. Measure flow, if it matches +/- 5% of setting, press the ON/
OFF key and resume sampling. Press and hold the SET
key to adjust the Factor for the pump speed to match de-
sired flow rate.
5. Press ON/OFF to return to Main Display and begin sam-

Section 6
Bubbler and Impingers Sampling
CAUTION: FIRST SET THE FLOW WITHOUT SOLUTION IN BUBBLER.
The default flow rate at 2000cc/min. or previously selected flow
may be too fast and draw bubbler solution into the pump.
Generally, 1,000 cc/min. is the flow of choice.
Connect a standard 37mm three piece filter cassette (with a
0.8 micron filter in place) close to the inlet of the pump. This
serves as a protective trap to prevent any fluids from being
drawn into the pump.
1. Attach a bubbler using desired length of hose to the input
of the cassette, so the order of the sampling train from
right to left (traveling upstream of the flow) is pump,
cassette and then bubbler as shown in drawing. Set flow
at 1,000 cc/min
2. Turn pump off, and next add solution to bubbler and
reinstall flow tube to holder.
3. Press Run begin sampling. Even though different brands
of bubblers/impingers have varying amounts of flow
resistance, the BUCK-Libra Series Pumps will operate at
the pre-selected flow.
