Waters Delta Prep 3000 Chromatography System

The Waters Delta Prep 3000 System is in good condition and tested at GenTech. It is an interactive, microprocessor-based liquid chromatography system that can be used for qualitative analytical and preparative scale chromatography. The system is suited, but not limited to, the separation of biological macromolecules. Includes NINETY (90) DAY WARRANTY.

Operational Specifications

Number of Solvents: One to four Modes of Operation: Gradient, isocratic, and flow programming Operating Flow Range: 0.50 to 80 ml/min (with optional 1/4" heads), 1.0 to 180.0 ml/min (with standard 3/8" heads) Composition Range: 0 to 100% programmable in 1 % increments for each of four reservoirs - A, B, C and D. Total composition must sum to 100%. Automatic Solvent Sparging: Standard, helium gas, input gas pressure range 50 to 150 psi. Sparge time adjustable from 1 to 100% of each minute. Pressure Maxima: 1800 psi (standard heads at 18 ml/min). 3400 psi (1/4" heads at 8 ml/min) Programmable Pressure Limits: - Upper: 900µl pump heads; 51 to 2000 psi - 400µl pump heads; 51 - 3400 psi - Lower: 900µl pump heads; 0 to 1999 psi - 400µl pump heads; 0 - 3350 psi Program Storage: - Storage for 8 programs that include multi-step gradient tables and setup parameters EEPROM preserves memory indefinitely following power loss or shut down. - Storage for a time-based multi-method program with up to 48 individual steps. - EEPROM stores setup parameters and tables and preserves memory indefinitely following power loss or extended shutdown. Gradient Profiles: Eleven gradient curves (including linear, step [2], concave [4], and convex [4]. Up to 80 curve segments can be linked. CRT: Display: 5" (12.7 cm) diagonal screen. Sixteen lines with 40 characters per line. Displays current operating conditions, time, and pressure. Allows operator to monitor complete gradient and timed event tables on single screens. Reverse video cursor prompts operator through program setup. Keyboard: Dedicated keys provide direct access to all display screens. Cursor movement keys simplify programming, editing and parameter entering. All keys are solvent resistant. Programmable Timed Events: Sixteen (16) timed events can be programmed and stored for each method.
