Modular Preparative HPLC Column Columns are stainless steel (one inch in diameter) and can be used separately or stacked, by using a modular adapter, to form custom-length columns. They are available in any length from 5 cm up, custom made or precut at the following lengths: 5, 10, 20, 30, 40, and 50 cm. The columns can be used with a low-pressure (100-1000 psi) or a highpressure (1000-6000 psi) solvent delivery system. HP Chemicals Inc. 413 Salt Analyzer Portable digital analyzer will measure the percent weight to salt in brine and other solutions. It has an accuracy of ± 0 . 0 1 % and the platinum-plated conductivity probe measures the conductivity of the brine in the range of 0 to 2000 ms. Temperature fluctuations of brine are automatically compensated for via a thermistor built into the probe. Extech International 414 Hydride System
