Laboratory homogenisers (stomacher / blender)
Laboratory blenders – BagMixer sample preparation systems
BagMixer laboratory blenders provide a reliable, standards-compliant solution for microbiological sample preparation in food, pharmaceutical, environmental and research laboratories.
The sealed-bag paddle blending technology ensures rapid, efficient and reproducible homogenisation of samples while minimising the risk of cross-contamination.
BagMixer systems comply with key international standards (ISO 7218, ISO 6887, FDA BAM), making them ideal for routine testing, validated methods and regulatory inspections.
Why BagMixer?
- Sealed-bag blending principle – safe and hygienic sample preparation
- Rapid and uniform homogenisation while preserving microorganism viability
- Wide sample volume range: from small sample quantities up to 3.75 litres
- Reliable construction designed for laboratory environments
- Multiple models and equipment levels for different applications
MiniMix series – for small sample volumes and targeted testing
MiniMix blenders are specifically designed for the rapid processing of low-volume samples. They are an ideal choice when only limited sample quantities are available or when a compact design is important.
Recommended applications:
- Rapid microbiological preparation of small sample quantities
- Teaching laboratories and research environments
- Targeted testing where sample quantity is limited
BagMixer 400 series – for standard microbiological sample preparation
The BagMixer 400 is one of the most widely used sample preparation solutions in microbiology laboratories. Its 400 ml capacity is ideal for homogenising food and environmental samples in accordance with ISO 6887.
Typical applications:
- Food microbiology
- Quality control (QC) laboratories
- Regulatory and routine microbiological testing
The various configurations (windowed door, quiet operation, liquid sensor) allow the instrument to be tailored precisely to the laboratory's requirements.
JumboMix 3500 series – for large-volume samples
The JumboMix 3500 is specifically designed to homogenise large sample quantities, with volumes of up to 3.75 litres. It is an ideal solution for industrial environments and applications where the sample size exceeds the capacity of standard laboratory blenders.
Recommended applications:
- Large food and environmental samples
- Industrial microbiological testing
- Research and development laboratories
Standards and compliance
The BagMixer laboratory blenders comply with the following standards and recommendations, among others:
- ISO 7218 – General requirements for microbiological examinations
- ISO 6887 – Sample preparation of food and animal feed
- FDA BAM – Bacteriological Analytical Manual
