The Automatic Capping Machine (BIO-BK-AC10) is a single-channel automated system designed for efficient screw-cap operations on laboratory sample tubes. The instrument employs diffuse reflection sensing to automatically detect tube presence, eliminating manual button activation during operation and reducing user fatigue in high-throughput workflows. Compatible with tube cap diameters ranging from 19.5 to 29.5mm, the system accommodates most standard laboratory sampling tubes through customizable gripper configurations.
Operating at speeds under 1.8 seconds per cap operation (opening or closing), the machine features one-hand operation capability and an integrated LCD display that tracks work quantity for operational feedback. The compact design (164×295×363mm) permits placement within biological safety cabinets, supporting containment protocols in clinical and research environments where sterile or controlled conditions are required.
How It Works
The Automatic Capping Machine operates through a diffuse reflection sensing system that automatically detects tube presence without requiring manual activation. When a capped tube is positioned in the gripper assembly, the optical sensor triggers the motorized mechanism to engage with caps ranging from 19.5 to 29.5mm in diameter. The system applies controlled torque to either tighten or loosen screw caps through a single mechanical operation.
The motorized gripper assembly adapts to different cap sizes through configurable gripper settings, ensuring consistent engagement across various tube types. The LCD display interface provides real-time feedback on operation count and system status, while the compact form factor allows integration into confined spaces such as biological safety cabinets. One-hand operation capability reduces ergonomic stress during repetitive capping tasks, with each complete cycle (cap engagement, rotation, and release) completed in under 1.8 seconds.

Practical Tips
Verify gripper alignment and torque consistency weekly using reference tubes with known cap tightness.
Why: Maintains consistent closure force across different tube types and prevents over-tightening that could damage caps or threads.
Clean the optical sensor window daily with lint-free cloth to prevent false detection signals.
Why: Contamination on the sensor surface can interfere with automatic tube recognition and cause operation delays.
Allow tubes to reach room temperature before capping if coming from refrigerated storage.
Why: Temperature differences can affect cap thread engagement and may cause inconsistent closure torque.
If the sensor fails to detect tubes consistently, check for proper tube positioning and ensure caps are within the 19.5-29.5mm diameter range.
Why: Detection issues often result from incorrect tube placement or attempting to process incompatible cap sizes.
Record the work quantity display reading at the start and end of each batch for documentation purposes.
Why: Provides accurate sample counting for quality control records and helps identify any missed operations during processing.
Ensure fingers are clear of the gripper mechanism before tube insertion to prevent pinching injuries.
Why: The automated operation begins immediately upon tube detection, leaving minimal time to clear hands from the mechanism.
Process tubes in consistent orientation with caps facing the same direction to optimize sensor detection.
Why: Uniform tube positioning reduces detection variability and ensures consistent gripper engagement across all samples.
Lubricate gripper mechanism monthly according to manufacturer specifications to maintain smooth operation.
Why: Regular lubrication prevents mechanical wear and maintains the sub-1.8 second operation timing specification.
