The DLC-20 and DLC-20P are complete HPLC systems with a variable wavelength detector built in at the price of most variable wavelength detectors alone. They combine a precision UV-Vis detector operating between 195-800nm with a time tested single piston pump to form low cost isocratic systems. Although not designed to replace the more expensive and larger systems, the DLC-20 and 20P, with their small size, price, and versatility are an ideal answer for routine QC analysis. Several DLC-20/20P can be dedicated to methods much less expensively than buying one larger and more expensive gradient system; particularly since most QC procedures are isocratic in nature.

The DLC-20 can be obtained in PEEK construction for bio- compatibility or in SS at the same price. The DLC-20P is available only in SS construction. Similar to the DLC-10CP/11CP the DLC-20P can operate to 5000 PSI with the standard 10ml pump head (SS). All controls are conveniently located on the front of the instrument. There are two LED displays. One is dedicated to the pump while the other displays detector absorbance and wavelength information. On the DLC-20P the pump display also indicates system operating pressure and preset alarm values. The rear panel has the analog voltage outputs for data acquisition and outputs for contact closures permitting remote control of absorbance and wavelength.

The DLC-20 comes standard with a two-stage valve and 20µl loop (either PEEK or SS). The 20P adds a position-sensing valve.
