Containment sampling CPS

Technology

HECHT offers advanced systems for vacuum-controlled sampling from containers, designed to ensure safety, accuracy, and process integrity within closed powder and bulk handling processes. These solutions are an integral part of the HECHT portfolio for sampling and containment in the pharmaceutical, chemical, and food industries.

Function & process overview

1. Container preparation with anti-crease ring

Before sampling begins, an anti-crease ring is placed around the container opening. This ring ensures a perfectly smooth lining and a repeatable seal, which is crucial for reliable sampling without product loss or exposure.
This is part of HECHT’s comprehensive range of containment sampling solutions (including CPS and CPP) specifically developed for OEB-classified processes.

2. Vacuum lance & secure attachment

A vacuum lance (sampling lance) penetrates the container wall in a controlled manner. A vacuum automatically and securely attaches the disposable sampler to the liner. This ensures that the interface between the sampling device and the process medium remains contamination-free and mechanically stable during sampling. HECHT’s sampling solutions include vacuum-controlled sampling technologies tailored to various product characteristics.

3. Drilling & sampling

Once the lance is correctly positioned, the system drills through the container in a controlled manner. This process takes place within a contained environment, ensuring the protection of both the product and the operator. The sample is then taken using optimised flow and vacuum control systems, resulting in high-quality, representative samples free from cross-contamination.

4. Sealing & cutting

After sampling, the sample is sealed and cut off using an integrated sealing mechanism. This minimises the risk of exposure and ensures that the sample remains securely sealed until analysis or distribution – a must in regulated environments such as those with OEB classifications.

Key technical advantages

• Repeatable sealing and sampling: ensures reproducible sample data, essential for quality control and release processes.
• Compatible with the HECHT ecosystem: integrated with vacuum conveyors, filling/discharge stations and containment components.
• Designed for high OEB levels: forms a key component in processes with strict exposure limits.
• Fully enclosed process: eliminates exposure of operators and the surrounding environment to active or potentially hazardous substances.

Industrial applications

This vacuum sampling method is used in sectors where:

• Safety and hygiene are top priorities, such as in pharmaceutical production and R&D.
• Contamination-free samples are required for batch release, QC analyses or process monitoring.
• Closed bulk processes are used for APIs, powders, granules or hazardous raw materials.

HECHT’s solutions are designed for integration into complex process lines and for modularity with other systems (such as vacuum conveying and dosing stations) to enhance overall process safety and efficiency.

How this solution fits into HECHT’s portfolio

HECHT’s product portfolio comprises a wide range of sampling systems, including:

• Vacuum sampling components for inline sampling.
• Containment sampling systems (such as CPS and CPP) for high OEB requirements.
• Single-use isolators (EPS/EWI) for safe, low-maintenance and low-cleaning sampling of critical substances.

These solutions are designed for integration into advanced production and quality environments, with a focus on safety, validatability and process control.

Summary

This vacuum-based sampling solution offers engineers a technically robust method for taking critical samples without compromising on safety or data quality. Thanks to its integration with HECHT’s extensive portfolio of containment and bulk handling systems, it is an excellent choice for high-integrity processes within regulated environments.
