Designation: D7353 − 07 (Reapproved 2013) D7353 − 21
Standard Practice for
Sampling of Liquids in Waste Management Activities Using
a Peristaltic Pump
This standard is issued under the fixed designation D7353; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This practice covers the use of a peristaltic pump for sampling liquids from multiple depths. It is applicable for a wide range
of fluids including: high-viscosity fluids, aggressive and corrosive fluids, high-purity solutions, and abrasive fluids. It is especially
useful for sampling liquids that require complete isolation from the pump.
1.2 This practice includes the determination of sample depth, pump set up setup, and collecting a sample to be analyzed.
1.3 This practice is not intended to give detailed instructions for running a peristaltic pump or to recommend which peristaltic
pump to purchase. It instructs the field personnel how to connect the pump and collect a sample.
1.4 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this
standard. All observed and calculated values shall conform to the guidelines for significant digits and rounding established in
Practice D6026. Reporting of test results in units other than SI shall not be regarded as nonconformance with this standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety safety, health, and healthenvironmental practices and determine the
applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4. Summary of Practice
4.1 A peristaltic pump is a suction lift pump (see Fig. 1b).(b)). A length of polytetrafluoroethylene (PTFE) or other suitable tubing
such as Silastic tubing is placed in the liquid at any depth up to 7.6 m (25 ft.)ft) for water or less depending upon the density of
the sample being taken. The other end is connected to the piece of flexible tubing which has been threaded around the rotor of the
peristaltic pump (see Fig. 1a).(a)). A second piece of PTFE or other suitable tubing is connected to the discharge end of the flexible
tubing to allow the liquid to be containerized or sampled. One can fill a vacuum-worthy sample container after attaching two tubes
to it, one from the top of the pump inlet, and the other from a lower level to the source (see Fig. 1c).(c)).
5. Significance and Use
5.1 This practice can be used in sampling drums, tanks, and similar containers and in sampling monitoring and waste wells
including small diametersmall-diameter (2.5 cm (1 in.)in.)) wells. The pump can collect samples from multiple depths. The
samples can be high-viscosity fluids, aggressive and corrosive fluids, high-purity solutions, and abrasive fluids. The pump can be
used to mix samples (see Guide D6063).
5.2 Peristaltic pumps use a vacuum to transport the samples. This vacuum may cause some degassing and loss of volatile organic
compounds (VOCs) from the sample. When precise quantitative data for VOCs and dissolved gases are not required, peristaltic
pumps may be used.
5.3 The pump is self-priming, runs dry without damage, and is completely isolated from the pumped fluid. A sample can be taken
on the intake or discharge side of the pump.

5.4 Some additional advantages of the peristaltic pump are: decontamination of the pump motor is not necessary and the tubing
in the pump is disposable and easy to replace. The pumps can be easily started and stopped and can pump fluids at a wide range
of pressures and flow rates.
5.5 The place, quality and quantity, frequency, and time of sampling isare dependent upon the decisions that are to be made (see
Practice D6250), sampling design (see Guide D6311), the sample, the heterogeneity of the samples (see Guide D5956), how
representative the sample is (see Guide D6044), and the parameters to be tested as determined by the data quality objectives
(DQOs) (see Practice D5792).
6. Sampling Equipment
6.1 It is recommended that two peristaltic pumps be taken to the site with two pump specific pump-specific clamps per unit.
NOTE 1—There are many peristaltic pumps on the market from several manufacturers. Consult with the manufacturers to determine the capabilities of
each pump for your application.
6.2 Two fully charged batteries (or other applicable batteries or AC/DC converter as required).
6.3 New medical-grade rubber/silicone tubing (Dow-Corning Silastic or equivalent). In corrosive situations, a length of PTFE
tubing is used.
6.4 Applicable tubing couplers for discharge and intake, as needed.
6.5 Tape measure or water level instrument.
6.6 Waste container.
6.7 Plastic, glass, or other non-reactivenonreactive containers should be used as specified by the site sampling plan (see Guide
D4687).
7. General Sample Collecltion
7.1 Review the work or sampling plan.
7.2 Check to make sure that the supply of sample containers, labels, ice chest, stop watch stopwatch or timing device, composite
collection container if required, and sampling equipment in place are adequate and correct. There should be sampling forms, or
log books, or equivalent for recording field information such as date, time the sample was taken, sampler’s name, physical
description of the sampling location, and any other information which might impact the validity of the sample. The log books,
sampling forms, and bottle labels should be signed or initialed.
7.3 Provision should be made for split samples and field quality control samples, such as trip blanks, equipment blanks, and field
spikes.
8. Pre-samplingPre-Sampling Testing
8.1 Remove the pump cover plate. Slide the tubing through the clamps, position the clamps in their seats, and gently rotate the
pump mast to engage the tubing in the pump housing. With the pump mast at the 6:00/12:00 position, the un-pinched tubing should
touch the walls of the pump housing (Fig. 1a).(a)). A little slack is desirable.
8.2 Tight
