Filtration of field water samples is not that easy. In discussions with customers, they’ve mentioned three alternatives that are available to accomplish the task, none of which are ideal:
- Use a manual vacuum pump. However, manual pumps can be weak and therefore very slow. And, they can wear you out if you have a lot of samples or ones with moderate-to-heavy particulates.
- Use a generator to power a standard lab bench vacuum pump. This option requires transporting the heavy generator and gasoline to the field water site.
- Transport samples back to the lab. Transportation requires the extra step of packaging the unfiltered samples, and means a delay in getting results and possible degradation of the sample depending on what is being collected and/or tested.
KNF engineers decided that a fourth option would be useful to field scientists, so they developed the new lightweight 12 volt mini-LABOPORT pump, model PJ26078-811. Designed specifically for in-the-field use where vehicle access is possible, it combines the robust operation of the traditional KNF LABOPORT pump with the ability to be powered via 12V DC car outlet. Therefore, field scientists can now rely on a lightweight oil-free vacuum source in environments where weight, portability, space, and timeliness often factor into operation.
Equipped with a three-meter long, coiled power cord fitted with a 12 volt car outlet adaptor cord and two 1/4” hose barbs for vacuum inlet and outlet, the new 12 volt mini-LABOPORT pump is ideally suited for filtration and gas sampling in the field. Its combination of compact convenience and reliable performance allow it to meet the needs of environmental companies, water treatment plants, field researchers, and anyone in need of a convenient vacuum source in remote locations.
Employing a compact, low-maintenance design, the pump is driven by a sturdy motor and features chemically-resistant construction. Providing up to 11 L/min flow at atmosphere, it offers 75 Torr (100 mbar) end vacuum.
