AI-Powered supplier vetting

SummaryBeijing WIIP Co. Ltd. is identified as both a trading company and manufacturer/factory, while related company information describes Beijing AUWII Science & Technology Co., Ltd. as a Beijing-based factory founded in 2007. The supplier reports ISO 9001, ISO 20000, and QC 080000 certifications, 21–30 years of combined R&D engineer experience, 6–10 quality-control staff, and eight production lines. Its products focus on temperature-control equipment and sample-pretreatment instruments. Reported annual capacities include 7,200 chillers, 8,600 oil-free air compressors, and 960 rotary evaporators, with off-peak lead times within 15 working days and peak-season fulfillment of one month. Export markets span multiple regions, but export sales are reported at only 21%–30%. The available trade records show one transaction for each of two chiller models with the same buyer, providing limited customer evidence. No direct evidence establishes after-sales performance, customization capability, or financial credibility.

Supplier typeThe supplier is explicitly classified as both a trading company and manufacturer/factory. Related company information identifies AUWII as a factory with headquarters in Changping District, Beijing, a production base in Yanjiao, and a focus on developing and producing temperature-control and sample-pretreatment equipment.

CertificationsThe supplier reports ISO 9001, ISO 20000, and QC 080000 certifications, and separately states that AUWII passed ISO 9001 and that products conform to CE standards. These reported certifications and conformity claims provide explicit evidence of quality-management and product-compliance credentials.

R&D capabilityThe supplier is described as a high-tech enterprise dedicated to research and development, with 21–30 years of total R&D engineer experience. Its product scope includes specialized temperature-control and sample-pretreatment equipment, supporting an explicit R&D capability assessment.

Production capacityThe supplier reports eight production lines and annual capacities of 7,200 chillers, 8,600 oil-free air compressors, and 960 rotary evaporators. It also reports fulfillment within one month during peak season and within 15 working days off-peak, indicating established production capacity and stated delivery capability.

Client casesThe company states that it passed a qualified supplier evaluation by a nuclear group, while trade records list SCIENCE RABBIT LLP as the buyer for two chiller models. However, the transaction evidence consists of only one recorded transaction for each model and provides no performance details or broader customer-case history.

Product Q&A

Q:What is the function of the microporous membrane?

The built-in PTFE microporous membrane efficiently filters air to prevent dust from contaminating the solvent and ensures the accuracy of analysis results.

Q:How does the cap prevent solvent volatilization?

It adopts a high-sensitivity non-return safety valve that closes and seals once the chromatographic instrument stops working, preventing mobile phase from volatilizing through the air inlet.

Q:How do I know when to replace the safety valve?

The cap features a time label with a red progress bar that records usage time. You should press the start button when first using it to track the time and replace the valve on schedule.

Q:How often should the safety valve be replaced?

It is recommended to replace the safety valve every 6 months. The quick plug installation design allows for easy replacement by users.

Q:What are the main applications for this product?

It is used for Liquid Chromatography, Automatic Solid Phase Extraction, and Pressurized Liquid Extraction in schools, hospitals, and labs.
