Hello, welcome to Union-Biotech (Shanghai) Co., Ltd!
Protein Purifier

Product Description

1.        The operating system is flexible and simple, allowing users to customize the configuration of hardware and software to meet a variety of purification needs.

2.        Dual plunger and binary gradient infusion pump and imported PEEK pump head to ensure high precision and reproducibility during the separation and purification process.

3.        Imported DAD full-spectrum detector is used for the UV detection, which has high wavelength precision and good repeatability. Dual channel simultaneous detection is to improve the convenience of detection.

4.        External UV detector flow-through cell, low dead volume and low peak width, improve chromatographic resolution.

5.        High sensitivity pH, conductivity, and UV detectors to improve chromatographic resolution.

6.        Equipped with pressure alarm and bubble sensor detection functions to improve system security and effectively protect chromatography column.

7.        The chromatography workstation is provided with computer and software, with powerful functions and advanced performance, which can efficiently and stably manage the chromatographic data. The functions of software comply with the relevant regulations of the CFDA and meet the requirement of the data traceability and security in the pharmaceutical industry.

8.        The instrument host and the collector can be stacked to effectively save space, the collector was a closed space to effectively prevent sample contamination.
