SMA Flow Cells

The SMA-Z Standard and Micro-Volume Flowcells have been designed for absorbance measurements where the monitored wavelengths are longer than 210 nm. The flowcells are available in 2.5, 5, 10, 20, 50 and 100-mm optical path lengths, with additional sizes available with special orders. Available materials include chemically inert Teflon, PEEK, Ultem, Steel and Plexiglas. The 10 mm SMA-Z standard Flowcell has a total internal volume of approximately 60 microliters. The Micro-Volume 10 mm version has an internal volume of approximately 8 microliters.

These flowcells utilize UV-grade fused silica windows, a hard, non-corrosive, chemically resistant material that also has a high UV through IR transmittance (210 nm through 2000 nm). The windows are held in place by chemically resistant seals, pressure mounted with steel SMA connectors (connectors do not contact the fluids). The windows are removable for cleaning or replacement with another material of different optical bandpass properties. The flowcell can be used with backpressures up to 800 PSI.

Each order includes one flowcell, two optical windows, two steel SMA connectors, two chemically resistant Upchurch tubing connectors, ten feet of Teflon tubing, six chemically resistant seals. Two SMA terminated fiber optic cables are required (P600-20 fibers are recommended). Order fibers separately. The detector of choice is the USB4000 spectrometer.

for optical paths less than 2.5 mm please see our USP flowcells.

SMA-Z flowcell is now available in polyetherimide (Ultem) for improved chemical resistance. Here is a partial list of common chemicals compatible with polyetherimide: Acetic Acid, Acetone Alconox Acetone, Alconox , Carbon Tetrachloride, Cellosolve, Chromic Acid, Citric Acid, Clorox, Cyclohexane, Cyclohexylamine, Ethanol, Ethyl Acetate, Ethyl Ether, Formic Acid, Gasoline, Hexane, Hydrochloric Acid, Isopropanol, Kerosene, Lestoll 1, Methanol, Methylethyl Ketone (MEK), Naphtha, Nitric Acid, Phenol, Phosphoric Acid, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Skydrol, Sodium Hydroxide, Sulfuric Acid, Tetrachloroethylene, Tin Chloride, Toulene, Trichloroethane (1,1,2-), Triethylphosphate, Xylene, Zinc Chloride.

SMA-Z-100 flowcell has an optical path of 100 mm. As with our other flowcells, it is available in PEEK, Ultem, Teflon, Plexiglas, and Stainless Steel. Other materials are available upon special orders.

The Micro-Volume SMA-Z flowcell is similar to the SMA-Z flowcell in principle, however it's built with a significantly smaller internal volume. The SMA-Z-Microvol 10 mm optical path flowcell has a total internal volume of less than 8 microliters. Compare this to ~60 microliters for the standard SMA-Z-10 flowcell.

Custom sizes and materials are also available, please contact FIAlab for additional information.
