Weilang Bio

Weilang Bio develops laboratory automation equipment focused on sample pre-processing for life science research and clinical diagnostics. Founded in 2015 by Wang Jian and Zhou Jianzhi, the company addresses critical bottlenecks in laboratory workflow automation, particularly in flow cytometry sample preparation where manual processing traditionally consumes significant technician time.

Company Overview

The company emerged from observations that Chinese research laboratories faced substantial inefficiencies in sample handling. According to industry surveys, sample pre-processing accounts for approximately 61% of total analysis time in chromatography workflows, while actual instrument analysis represents only 6%. This imbalance creates what laboratory professionals commonly describe as repetitive manual work that diverts researchers from higher-value scientific activities.

Wang Jian, who trained in clinical medicine at Third Military Medical University before gaining experience in the United States, identified laboratory automation as an underserved market segment. His co-founder Zhou Jianzhi brought pharmaceutical expertise to the venture. Together, they positioned Weilang Bio not merely as an equipment manufacturer but as a provider of integrated automation platforms for scientific research applications.

The company operates on a “customize first, then batch produce” business model. This approach allows Weilang Bio to develop specialized solutions for specific customer requirements before scaling production for broader market applications. Flow cytometry detection, given its widespread use in both research and clinical settings, became the primary focus for initial product development.

Core Products

ReadyGo Sample Processor

ReadyGo represents the company’s first-generation flow cytometry sample processing system. Designed for flexibility, it offers broad functionality for various sample preparation protocols. The platform requires users to program experimental workflows, providing adaptability for diverse research applications but demanding greater operator involvement during setup.

UItron Automated Workstation

UItron emerged as a refined solution addressing customer feedback about ReadyGo’s complexity. This second-generation platform processes 48 samples in parallel per run, targeting both research and clinical flow cytometry applications.

The system’s core innovation involves proprietary microfluidic liquid exchange technology that eliminates centrifugation from cell washing procedures. Traditional centrifuge-based washing presents a significant automation bottleneck due to mechanical complexity and processing time requirements. UItron’s approach maintains higher cell preservation ratios and viability compared to centrifugation methods while producing samples with improved staining indices.

The workstation integrates pipetting, temperature control, and light-protected incubation modules to automate antibody staining, cell incubation, and washing steps. Pre-configured protocols for common assays reduce operator training requirements, while customization options accommodate specialized workflows.

Custom Automation Solutions

Beyond standard products, Weilang Bio develops application-specific equipment including protein chip spotting instruments and qPCR loading systems. These custom solutions address niche laboratory automation needs that standard commercial platforms may not efficiently serve.

Technology Platform

The company’s technical foundation centers on microfluidic-based sample handling. This approach enables gentle, centrifugation-free processing that preserves cellular integrity—a critical factor for flow cytometry applications where cell damage directly impacts data quality.

Weilang Bio has extended its capabilities into automated service platforms covering high-throughput transcriptome sequencing (Easy-RNASeq), array-based detection (AutoArray), and customized qPCR services. Additional platforms for next-generation sequencing, T-cell receptor library construction, and cell culture automation are under development.

Market Position

Operating in the laboratory automation segment, Weilang Bio competes against established international manufacturers that have historically dominated the Chinese market. The company positions its products as cost-effective alternatives to imported equipment, addressing concerns about high acquisition costs and expensive maintenance that limit automation adoption in Chinese research institutions.

The sample pre-processing automation market serves academic research laboratories, clinical diagnostic facilities, and pharmaceutical development organizations. Flow cytometry applications span immunology research, hematology diagnostics, oncology studies, and cell therapy manufacturing quality control.
