Tedlar bags are recommended for the collection of final
TCLP volatile extracts and the liquid portion of multi-phasic
samples. These 7"x7" one-liter bags are also suitable for
aqueous and gaseous sample shipment and storage. Our
Tedlar bags are manufactured from 2mil Tedlar film and are
available with either single or dual fittings. The single fitting
bag has a septum valve for use with a syringe. The septum
valve can be unscrewed to gain wider access to the bag. The
dual fitting bag has an on/off tubing valve as well as the

Fluid Metering Pumps
Metering pumps provide the easiest and most
accurate method of transferring exact amounts
of liquids into a zero head space extractor. Delta
Scientific offers a variety of pumps and appropriate
Teflon fittings suitable for numerous applications.
Fittings for individual needs are readily available on
a special order basis. All pumps listed use 115VAC.
Adaptor Kits for Pumps
These preassembled adaptor kits provide the correct
tubing and fittings to connect the above metering
pumps to a zero head space extractor and an
extraction fluid reservoir. The kit consists of two 24"
sections of PTFE tubing and fittings manufactured
from Teflon and/or 316 stainless steel.

TCLP Syringes for Volatile Sample Collection
When a volatile sample is collected for TCLP analysis, a major concern is to
minimize the loss of volatile constituents. Our TCLP gas tight syringes use a
unique locking valve that allows sample extract to be drawn directly out of the
zero head space device and stored in zero head space condition until injected
into a GC/GCMS or a purge and trap. These reusable TCLP syringes have
wetted surfaces of borosilicate glass, Teflon and/or 316SS. Available in 5mL,
10mL, 25mL, 50mL, and 100mL sizes.
