Our Clearline Bailers use clear polyethylene which is so inert that the FDA approves its use for water and soft drinks. Put it together with HDPE top fittings and bottom valves and it becomes the clear choice for clear bailers. To overcome the concerns caused by PVC in sampling applications extrusion engineers and resin chemists helped design a clear polyethylene for superior sample results and performance characteristics.
Other bailers use rigid, clear PVC tubes and and coloured ABS tops and bottoms. PVC is both adsorptive and absorptive and the vinyl chloride in PVC can be a contaminant issue both during sampling and after disposal of the device. ABS can both adsorb and absorb compounds which can provide falsely conservative results. Also, the plasticizers used in ABS can leach into samples.
The SingleSample Bailer Retrieval System: It's easy to use, eliminates cross-contamination and speeds up sampling.
You know the routine:
Well now there is an easier way: The SingleSample Bailer Retrieval System.
The Bailer Retrieval System features a 7" reel with free-spin preventer that makes bailing and sampling faster and easier. The prewound, disposable twine eliminates cross-contamination. A Well Head Bracket is also available to support the reel and bailer while purging and during sample removal through the bottom valve.
Twine is provided on 4" cores in 30 or 60 metre lengths.
Conventional, reusable Teflon bailers are hand machined out of solid rod and block stock in a machine shop environment, which potentially exposes them to violate compounds. The result is a product that, from its initial manufacture, requires decontamination.
SingleSample Teflon and polyethylene disposable bailers are produced under entirely different conditions. The top piece, bottom valve and removal device are injection moulded whilst all tubing is extruded (These processes all take place off-site from the assembly facility). Since Teflon and polyethylene are naturally slick, there are no lubricants of any kind used in any of these processes.
The resin in all SingleSample polyethylene products is natural, virgin, high-density polyethylene. No regrinds are accepted and the same material is used consistently from run to run. The polyethylene used in SingleSampleŽ products contains no plasticizers or additives.
Once the parts are moulded or extruded, they are packaged and shipped directly to the assembly facility. Immediately prior to the assembly, all parts and tubing are washed in LiquinoxT Detergent and individually rinsed with DI water. this is precautionary step taken to remove any traces of compounds that may have found their way onto the tube through touch-transfer or other means in the manufacturing phase of production.
After the wash and rinse step, all parts and tubing are allowed to air dry in a controlled room. After drying, these parts are assembled and individually inserted into polyethylene bags. Tese are 2 mil. thickness bags that do not require or contain any plasticizers.
After bagging, bailers are packed in natural corrugated boxes that are assembled using exterior tape only to eliminate glues containing volatiles that are sometimes used in this form of packaging.
The following special cleaning procedure is available for SingleSample bailers. This cleaning procedure supplements the regular manufacturing and cleaning procedure and all steps not outlined here remain unchanged.
Under this procedure, all components are:
The following special cleaning procedure is available for SingleSample bailers to meet New Jersey cleaning requirements:
To overcome the concerns caused by PVC in sampling applications. Voss Technologies worked with both extrusion engineers and resin chemists to specify a clear polyethylene for superior sample results and performance characteristics.
Other clear bailers use rigid, clear PVC tubes coloured ABS tops and bottoms.
PVC is both adsorptive and absorptive and the vinyl chloride in PVC can be a contaminant issue both during sampling and after disposal of the device. ABS can both adsorb and absorb compounds that can falsely conservative results and the plasticizers used in ABS can leach into samples.
ClearLineT Bailers use clear, extruded polyethylene for the main tube section and natural, high density polyethylene (HDPE) for the top fitting and bottom valve parts.
HDPE is an inherently inert resin that does not leach compounds into, and does not adsorb or absorb compounds out of samples.
Clear polyethylene's chemical compatibility meets or exceeds clear PVC's performance without any vinyl chloride. Together, these resins clearly make ClearLine Bailers the superior choice.
