Fully Automatic Stainer and Coverslipper: Intelligent, High-Throughput Slide Processing for Modern Pathology Labs

In modern histopathology laboratories, staining and coverslipping are critical steps that directly affect slide quality, workflow efficiency, and diagnostic consistency. The Xiuwei Fully Automatic Stainer and Coverslipper integrates intelligent staining and coverslipping technologies into an automated workflow, helping laboratories process large slide volumes with less manual handling and more consistent results.

Designed for high-throughput pathology environments, the system combines flexible station configurations, intelligent reagent management, precision robotic movement, and automated coverslipping to create a more efficient and standardized slide preparation process.

1. Integrated Staining and Coverslipping

The system supports both automatic staining and automatic coverslipping, with the two functions available independently or as an integrated workflow. After staining, slides can be transferred directly to the coverslipper through the integrated track, eliminating the need for a separate transfer device and reducing manual handling.

2. High-Throughput Slide Processing

The Xiuwei automatic stainer is designed for laboratories with demanding workloads:

• Up to 500 slides/hour with double-row configuration

• Up to 400 slides/hour with triple-row configuration

• Coverslipping speed of up to 400 slides/hour

• Maximum one-time staining capacity: 30 slides

This high throughput helps laboratories reduce processing bottlenecks while maintaining standardized staining and coverslipping quality.

3. Flexible Station Configuration

Laboratories can select configurations according to their workflow requirements:

• Double-row: 26 stations

• Triple-row: 39 stations

• Up to 11 programs can run simultaneously

• Supports common staining protocols, including HE and Pap staining

With up to 200 stored programs, laboratories can easily manage frequently used protocols and adapt the system to different staining requirements.

4. Fully Enclosed Design and Gas Monitoring

The fully enclosed design helps create a cleaner and more controlled working environment. The system is equipped with dual exhaust gas sensors, supporting gas concentration monitoring from 0–100 ppm.

This provides laboratory personnel with additional environmental monitoring during automated staining operations.

5. Intelligent Reagent Management

Reagent status is displayed using intuitive green, yellow, and red alerts, making it easier for operators to identify reagent conditions at a glance.

The system also provides reagent usage statistics, helping laboratories monitor consumption, schedule replacement, and improve reagent management.

6. Precision Robotic Arm and Corrosion-Resistant Rack

A precision three-axis robotic arm enables smooth and accurate slide movement. The 90° immersion design supports stable and consistent staining operations.

The staining rack is made from corrosion-resistant PBT material and accommodates 30 slides per rack, providing durability for repeated use in laboratory environments.

The automated coverslipper is designed to provide stable, repeatable coverslipping results. Its precision glue dispensing system helps control adhesive application, while automated pressing minimizes bubbles and improves coverslip positioning.

Key advantages include:

• Precise glue dispensing

• Bubble-free pressing

• Stable coverslip positioning

• Consistent coverslipping quality

• Support for glue-free coverslipping

• Compatibility with slides, coverslips, and sealants from 4+ brands

The slide tray holds up to 120 slides, arranged as 20 slides per layer across six layers. A buffer design helps maintain smooth slide feeding and protects workflow continuity.

The system also incorporates broken-slide detection, with voice and color alarms to alert operators and help prevent damaged slides from affecting subsequent processing.

For busy pathology laboratories, automation is not simply about increasing speed. It is also about reducing repetitive manual work, minimizing slide handling, and improving process consistency.

By connecting staining and coverslipping through a direct integrated track, the Xiuwei system reduces the need for operators to manually transfer slides between separate instruments. Automated reagent management helps reduce monitoring workload, while programmable protocols improve repeatability between batches.

For laboratory managers, this can translate into more efficient staff utilization, fewer manual handling steps, and a more standardized slide preparation workflow.

For distributors, the flexible double-row and triple-row configurations provide options for laboratories with different throughput requirements, making the system suitable for a broad range of pathology applications.

The Xiuwei Fully Automatic Stainer and Coverslipper combines high-throughput staining, intelligent reagent management, precision robotic handling, and automated coverslipping in one streamlined workflow.

With up to 500 slides per hour, up to 39 staining stations, multi-program operation, direct track transfer, and advanced slide quality protection, it provides a practical automation solution for laboratories looking to improve efficiency without compromising process consistency.
