Guide and selection support
Stomachers are used in microbiological laboratories to homogenize samples quickly and gently. They assist in the release and distribution of microorganisms from solid or liquid samples contained within sterile plastic bags.
Key selection criteria include processing capacity, paddle movement mode, and user-friendliness of the device. The volume of the sample bags and hygiene requirements are also decisive factors.
LabFinder helps you by providing a clear overview of relevant technical features and usage characteristics, enabling users to quickly identify suitable stomacher models for their microbiological laboratory needs.
Applications and Benefits
A stomacher is used for sample homogenization in microbiological laboratories. By the mechanical action of two paddles on samples within sterile plastic bags, the sample is broken down, dispersed, and homogenized. This facilitates the extraction of soluble substances and the recovery of even deeply embedded microorganisms. After processing, the liquid sample can be easily withdrawn with a pipette. Typical applications are microbiological examinations, food safety testing, and environmental analysis.
Selection Criteria
When choosing a stomacher, the device's volume capacity and the compatible sample bags are critical factors. Ease of use and cleaning of internal parts are also important, as hygiene is essential for microbiological applications. The type of paddle movement should ensure efficient and gentle sample processing. Additional features such as programmable time and speed controls may be relevant depending on requirements.
Variants and Functionality
Stomachers operate with two paddles that strike or rotate against each other, mechanically working the sample in a sealed bag. Variants mainly differ in size, the number of sample bags that can be processed simultaneously, and the adjustability of movement parameters. Devices are available with standard atmospheric or sterilizable features depending on the area of application.
Calibration and Maintenance
Regular cleaning is crucial to avoid contamination. Mechanical parts should be checked for proper function and wear. Classical calibration is not required, as these devices perform purely mechanical sample processing, though it is recommended to check device settings regularly.
Limitations of Application
Stomachers are not suitable for all types of samples, especially those with extremely high viscosity or particularly tough materials. Other laboratory homogenizers are better for producing finer homogenates or performing cell disruption. The sample must also be placed within a suitable bag to prevent device damage or sample loss.

Frequently asked questions
How does a stomacher work?
A stomacher operates with two paddles that mechanically break up and mix the sample within a sterile plastic bag. This movement distributes the sample evenly and facilitates the extraction of microorganisms or soluble substances.
What types of samples are suitable for a stomacher?
Stomachers are mainly suitable for solid or semi-solid microbiological samples placed in sterile, flexible bags. They are less effective with highly viscous or tough samples.
What criteria are important when selecting a stomacher?
Important factors are the size and capacity of the device, compatibility with various bags, hygiene requirements, user convenience, and optional programmability for movement time and speed.
How is a stomacher maintained?
Regular cleaning and inspection of mechanical components are essential. Calibration is not required, but functions and settings should be checked to ensure consistent sample homogenization.
What are the limitations of stomacher applications?
Stomachers cannot homogenize all samples, particularly not highly viscous or very tough materials. They are only suitable for samples that can be processed in sterile bags, as the paddles rely on acting directly on the bag.
