Introducing the WelPrep 2000 G2: The Next Evolution in Preparative HPLC

The WelPrep 2000 G2 introduces several hardware and structural improvements aimed at optimizing daily laboratory operations:

• Advanced Visual Interface: Both the solvent delivery pumps and the detectors are now equipped with 7.0-inch IPS high-definition LCD screens (1024 × 600 resolution). These displays support 65K colors and an 85° wide viewing angle, ensuring that instrument status and parameters are clearly visible from across the laboratory.

• Optimized Structural Design: The manual injection valve features a novel drawer-style design, significantly simplifying the process of replacing sample loops and performing routine maintenance.

• Versatile Modular Configuration: The system supports flexible arrangements to meet diverse purification scales. New features include a solvent recovery and recycling function to reduce operational costs and environmental impact.

• Expanded Compatibility: The updated GalaChrom software is fully compatible with Sail1000 and HT1500L autosamplers, providing users with a broad range of configuration options.

• Intelligent Control: The software provides a redesigned human-machine interface (HMI) available in multiple languages, providing intuitive display of parameter configurations and system status.

Features advanced electronic pulsation compensation and multi-point flow calibration for high precision across the entire flow range. Pump heads are available in SS316L, PEEK, PTFE, or Hastelloy to ensure compatibility with diverse mobile phases. Includes integrated automatic detection of pressure exceptions for enhanced operational safety.

A dual-wavelength detection system offering high sensitivity and a wide linear range. Supports deuterium or tungsten lamps with multi-point wavelength calibration, time-programmable tasks, and a dedicated display. The universal sample cell is compatible with various optical pathlengths to meet diverse detection requirements.

Supports continuous or repeated injections of multiple samples. Equipped with a 25 mL high-precision syringe and PTFE-coated peristaltic pump. Supports a wide injection range (0.1–25 mL), handles viscous samples, and includes an integrated bubble sensor for continuous, high-throughput processing. Features automated pre-injection liquid addition, derivatization, and dilution, as well as dedicated cleaning channels allowing for automated washing and draining.

Upgraded to 16 channels with a new sample purging function to maximize recovery rates. Features low dead volume and minimal diffusion, supporting green lab initiatives via separate waste collection channels and solvent recovery. Designed for ease of maintenance with online cleaning and evacuation capabilities.

Includes a built-in make-up pump for one-key automated filling, cleaning, and draining, and a unique Y-type buffer structure to stabilize pressure, minimize dead volume and sample diffusion. This module significantly improves resolution for complex separations without the need for additional columns or extra solvent consumption, saving preparation costs.

An intuitive, multi-language (Chinese/English) workstation that integrates instrument control, data acquisition, and processing. Provides real-time visual monitoring of system status and ensures full compliance with GMP and FDA 21 CFR Part 11 regulations. Includes robust multi-level permission management and comprehensive audit trails to guarantee data integrity and traceability.
