STAINLESS STEEL GAS TIGHT SYRINGE
<a href=”http://lasallescientific.com/associated-design-stainless-gas-syringe/“>STAINLESS STEEL GAS TIGHT SYRINGE</a>
|The Associated Design Model 3790-
GTS Gas Tight Syringe was developed
to collect the filtrate and transfer
extraction buffers for the analysis of
volatile leachates during the Toxicity
Characteristic Leaching Procedure
(TCLP) U.S. EPA Method 1311 and the
Synthetic Precipitation Leaching
Procedure (SPLP) U.S. EPA Method
The gas-tight syringe is a useful
accessory for the 3745-ZHE and 3740-
ZHE Zero Headspace Extractors by
permitting the sealed collection of
volatile pollutants without losses due to
Complies with USEPA Specifications
The 3790-GTS is a suitable filtrate
collection container for use in
performing TCLP or SPLP. All wetted
parts are made from stainless steel.
Standard Viton® O-rings are used
throughout. The syringe has a nominal
capacity of 100 ml.
Facilitates Filtrate Collection
To use the 3790-GTS for filtrate
collection, attach the syringe directly to
the “Speed Nut” on the ZHE, open the
sample valve and collect the filtrate in
the gas-tight syringe. The syringe can
be cooled to 4 degrees C as required
for storage of volatile waste samples.
Built for Durability and Convenience
Virtually unbreakable, the 3790-GTS
has a unique 0-100ml dual scale that
permits fast determination of fluid
volumes. A proprietary shut-off/metering
valve and Viton® o-ring seals prevent
leakage and insure sample integrity.
The new Teflon® piston cup allows
easier syringe movement for loading
extraction buffers without stiffness or
binding. Fast disassembly by hand
facilitates cleaning for reuse. The 3790-
GTS is provided with a .25-inch o.d.
connection on the end of the valve or it
can be supplied with an optional male
No Tools Required
When used in conjunction with the
Associated Design Zero Headspace
Extractors and Rotary Agitators, no
tools are needed to perform the
complete TCLP extraction.Options
The 3790-GTS can be ordered with a
male luer lock adapter.
Proven and Tested
The Associated Design Gas-Tight
Syringe has been used by major
laboratories world-wide since
1987 and is a suitable TCLP device.
LIQUID RELEASE TEST DEVICES
|The Associated Design Model 3760-LRT Liquid Release Test Device is a laboratory or field unit designed to perform the proposed Liquid Release Test (U.S. EPA Method 9096) on sorbent materials used inside hazardous waste containers. Complies with USEPA Specifications
The 3760 LRT is a piston-based, pressure activated device capable of detecting liquid released from an overloaded sorbent where the saturation concentration is exceeded by as little as 10%. Sorbent samples in the 3760-LRT
are subjected to simulated landfill overburden conditions of 50 psi during the test.
Convenient Sample Loading
No False Releases
