The standard grade optics have a typical RMS roughness of 8-10 angstroms, whereas laser grade optics have typical roughness values of only about 4 angstroms. Our scatterometer uses a 405 nm laser in transmission mode near Brewster’s angle.
The hydrophobic PVDF membrane syringe filters are suitable for organic solvent and air filtration. Even under a very low-pressure difference, it can ensure the unhindered passage of moist air or other gases, while the aqueous solution cannot pass through. Hawach filters such as 0.45um PVDF syringe filters are sold all over the world and have

Aug 19, 2011 · The dry residues were reconstituted in 250.0 μL mobile phase and filtered through 4 mm disposable polyvinylidene fluoride (PVDF) syringe filters with a pore size of 0.45 μm (Whatman Inc., Piscataway, NJ, USA). The extraction recoveries with Oasis MCX and Evolute CX-50 cartridges were determined for fluoxetine-d 5 and norfluoxetine-d 5.

Sterile PVDF syringe filters are commonly used in the chemical process industry (including pipes, fittings, pumps, valves, etc), off-shore oil industry (multi-layer structures for oil and gas), high purity fluid transportation, wire and cables, plumbing, and lithium batteries.
The Eliminator is a high capacity bladder pump designed for LNAPL and DNAPL removal in 2” (50 mm) and 4” (100 mm) wells. The Eliminator is also used to handle viscous contaminants, such as crude oil. The Eliminator uses a bladder of PTFE or elastomer to isolate the pump air supply from the pumped liquid.

Jan 12, 2021 · This paper investigates the potential use of anthracite coal to remove Fe, Mn, UV254, and colour from pre-ozonated groundwater using batch experiment studies. Pre-ozonated groundwater samples were prepared in a laboratory to present the actual characteristics of groundwater samples. General characteristics for anthracite, as well as for groundwater samples, were examined. The influences of
When selecting the syringe filter, consider the volume of the sample (that is, what size of the syringe filter is selected): Generally, when the sample amount is less than 2 ml, a 4 mm diameter micro-filter is used. The sample volume is between 2-10ml, and the 13mm diameter filter is suggested to use.
