VST Portable Vacuum Fluid SamplersManning Model VST portable samplers employ 3/8-inch ID or 5/8-inch ID vacuum pumps to provide suction lift. These samplers have few moving parts and all critical components are rated for thousands of operations. Since these samplers utilize vacuum pumps, labor and spare parts costs are minimized because they don't require regularly scheduled replacement of consumable parts such as peristaltic pump tubing. VST samplers provide accuracy and repeatability of sample volumes within 0.5% of pre-set volume. Changes in vertical or horizontal head height will not affect sample volume taken, since the sample is volumetrically measured. The collected sample will be exact, ensuring the validity of your sampling data. |
