L/C buyer's tip: Don't pay $5,000 for the cabinet
:
A Model 1440 high pressure liquid chromatograph can give you separations and operating convenience identical to practically any $9,000 fancy cabinet competitor. ISCO constant flow 2,000 psi gradient or metering pumps have absolutely pulseless, vibrationfree single stroke piston construction. You don't have to settle for a gas pressure system (with you supplying the gas), or septum injection. The 6 port sample injection valve permits rapid and reproducible sample introduction. Stainless steel columns have nonclogging supports and fittings with no dead volume or mixing. The dual beam, high sensitivity UV photometer has eight absorbance ranges from 0.01A to 2.0A full scale, and instant w a v e l e n g t h selection of 2 5 4 n m or 280nm. The whole chromatograph as pictured—pump, column (unpacked), photomerer,10cm recorder, and sample inject ion valve, costs under $4,200.Many additional features and options are available, all described in our current catalog.
