Whether for quality control of incoming or outgoing products, laboratory testing or other areas of quality control, HECHT's innovative Single-Use Sampling System (EPS) allows sampling of highly active or hazardous substances from small containers without extensive protection or cleaning measures.
The use of a flexible protective film in combination with a connection adapter ensures operator and product protection. Combining containment, flexibility and efficiency, the EPS is an important element of quality management in most companies.
Safety and Quality
- Primary Containment due to protective foil
- Quick and easy sampling without special protective equipment
- Contamination-free sampling
- High-Containment: OEL: up to 1µg/m³ (OEB 5) -in laminar flow cabins: up to 200 ng/m³(OEB 6)
Flexibility
- Adaptable to different kinds of bins and applications (customizable)
- Process control adaptable to OEL-requirements
- Inertisation
- Wall mounting, mobile version or permanent installation of the EPS possible
Cost saving
- Low investment and maintenance costs
- Hardly any cleaning costs
- No effort for cleaning validation
- Short changeover times
- The system is divided into a fixed and flexible part
- Fixed part: stainless steel frame with working surface, dedusting unit, and intake for single-use isolator
- Control unit is customized to OEL requirements, operates in underpressure mode with or without inertization
- EWI supports various processes with ports for customized manipulations (e.g., magnetic stirrers, weighing systems, power and air feedthroughs)
- Multiple loading/unloading ports and gloves can be integrated as needed
- All versions are GMP-compliant
- Sampling takes place inside the foil isolator via gloves
- Single-use foil is mounted into the fixed frame, and interfaces are connected
- Pneumatic seal or vacuum plate stabilizes the isolator, making the system operational
- Bin with product to be sampled is placed under EPS, outer liner is attached to the connection port via double O-Ring
- Operator uses gloves to open the foil and inner liner, removes sample with sampling vessel in the sampling hose
- Hose is double tied off and cut, keeping both the isolator and bin sealed
- After sampling, inner liner is closed and pushed back into the bin, outer liner is double tied off and cut
- Pneumatic seal is deactivated, foil isolator is removed, and a new cycle begins without delay
- Isolator is disposed of after product handling, no cleaning or decontamination required
- EPS is ideal for sampling bulk solids from small bins or for processes requiring two liners
- Compact station is transportable with a hand pallet truck or roller feet
- Requires only a 230V power supply and 1 bar compressed air
