Brinkmann/Seward Stomacher 80 Lab Blender – Used and Refurbished
The Brinkmann/Seward Stomacher 80 Lab Blender is a compact laboratory paddle blender and tissue homogenizer designed for small-volume biological sample preparation. Developed for clinical, life science, microbiology, tissue-processing, and research applications, the Stomacher 80 provides gentle but effective mechanical processing of samples inside disposable bags, helping laboratories prepare cell suspensions and homogenates while minimizing direct contact between the sample and the instrument.
Designed for sample volumes from approximately 5 to 80 mL, the Stomacher 80 is substantially smaller in capacity than general-purpose models such as the Stomacher 400. Its compact sample range makes it particularly useful for tissue specimens and other biological materials where conserving sample volume and recovering viable cells are important considerations.
Samples are processed inside disposable Stomacher bags using reciprocating paddles rather than rotating blades. This bag-based approach eliminates direct sample contact with the blender mechanism, simplifies cleanup between specimens, and helps reduce the risk of cross-contamination.
The Stomacher 80 provides three selectable paddle speeds of approximately 230, 265, and 300 rpm along with 30-, 60-, and 120-second processing cycles and continuous operation. Adjustable paddle clearance from 0 to 10 mm allows the blending action to be adapted to different sample characteristics.
This Brinkmann/Seward Stomacher 80 is used and refurbished by American Instrument Exchange. AIE technicians test the blender before shipment to verify paddle movement, speed selection, timer functions, controls, and general mechanical operation. The instrument is thoroughly cleaned and includes a 90-day warranty.

Overview
The Stomacher 80 is designed specifically for laboratories working with smaller biological specimens.
Rather than attempting to scale down a conventional blade blender, the Stomacher uses reciprocating paddles that act against a sample contained inside a disposable bag.
The paddles repeatedly compress and manipulate the specimen, creating mechanical homogenization without requiring rotating blades to contact the sample directly.
For life science and microbiology applications, this approach provides an important advantage: the sample remains enclosed within its own processing bag.
Once processing is complete, the bag can be removed and the resulting suspension or homogenate used for appropriate downstream laboratory procedures.
Common Applications
The Brinkmann/Seward Stomacher 80 can support tissue homogenization, preparation of viable cell suspensions, clinical sample preparation, microbiology research, life science applications, biological sample processing, cell-recovery procedures, small-volume sample extraction, tissue-culture preparation, and other workflows requiring controlled mechanical processing of relatively small specimens.
It can also be useful when a laboratory needs to homogenize a biological sample without exposing it directly to the reusable components of a conventional blender.
The Stomacher performs sample preparation rather than downstream analysis. Appropriate analytical, culture, microscopic, molecular, or other methods are used after the sample has been processed.
Ideal Laboratory Types
The Stomacher 80 is well suited to biomedical research laboratories, clinical research facilities, microbiology laboratories, biotechnology companies, pharmaceutical research laboratories, tissue-culture facilities, academic research laboratories, veterinary research facilities, cell-biology laboratories, contract research organizations, and other laboratories working with small biological specimens.
Its combination of small-volume capacity and disposable-bag processing can be particularly useful in laboratories where sample conservation and contamination control are important.

Small-Volume 5–80 mL Sample Processing
The defining characteristic of the Stomacher 80 is its small sample-volume range.
The standard Stomacher 80 Biomaster platform is designed for specimens between approximately 5 and 80 mL.
This makes it particularly useful for biological and tissue samples where processing hundreds of milliliters of material would be unnecessary or undesirable.
Small-volume capability can also reduce the amount of diluent required for appropriate procedures and allows laboratories to process limited specimens more efficiently.
Tissue Sample Preparation
Seward developed the Stomacher 80 platform specifically with tissue and life science applications in mind.
A tissue specimen can be placed inside an appropriate disposable bag and subjected to controlled paddle action.
Rather than cutting the tissue with high-speed blades, the paddles mechanically manipulate the specimen through the bag wall.
The appropriate processing conditions depend on tissue type, sample size, downstream procedure, and the degree of disruption required.
Preparation of Viable Cell Suspensions
One of the most interesting applications for the Stomacher 80 is preparation of viable cell suspensions from tissue specimens.
Seward specifically positions the Biomaster platform for applications where cell recovery and viability are important.
The paddle-based mechanism provides a different type of mechanical action from high-speed blade homogenization.
For appropriate tissues and laboratory protocols, this can help release cells into suspension while avoiding some of the aggressive shear associated with other homogenization technologies.
Final cell yield and viability depend on specimen characteristics, processing time, paddle speed, bag configuration, buffer, temperature, and the complete sample-preparation method.
Three Selectable Paddle Speeds
The Stomacher 80 provides three no-load paddle speeds.
LOW operates at approximately 230 rpm, NORMAL at approximately 265 rpm, and HIGH at approximately 300 rpm.
Multiple speed settings allow the operator to adapt processing intensity to different specimens.
A delicate biological sample may benefit from different conditions than a more resilient tissue specimen.
Once suitable conditions have been established, repeatable speed selection can help standardize sample preparation between specimens and operators.
Timed and Continuous Operation
The Stomacher 80 provides fixed processing times of 30, 60, and 120 seconds.
Continuous operation is also available for procedures requiring a longer or manually controlled processing period.
Fixed timers simplify routine protocols because an operator can select an established processing duration rather than manually timing every specimen.
Consistent processing time is particularly useful in research procedures where sample preparation needs to be reproduced across experimental groups.
Adjustable Paddle Clearance
Paddle clearance can be adjusted from approximately 0 to 10 mm.
Clearance determines how closely the paddles act against the sample-filled bag and therefore influences the mechanical processing action.
Different specimen sizes and compositions may require different settings.
The appropriate clearance should allow effective sample manipulation without placing unnecessary stress on the bag or specimen.
Disposable Bag Processing
The Stomacher system processes each sample inside a disposable bag.
The specimen and any required buffer, medium, or diluent are placed inside the bag before loading it into the blender.
During operation, the paddles contact the outside of the bag while the biological material remains enclosed.
After processing, the bag is removed and can be taken directly to the next stage of the laboratory workflow.
This eliminates the reusable blender jar that would otherwise need to be thoroughly cleaned between biological samples.
Reducing Cross-Contamination
Preventing carryover between specimens is particularly important when working with biological samples.
Because each sample is contained within a separate disposable bag, the Stomacher approach greatly reduces the number of reusable instrument surfaces that come into contact with specimen material.
This can simplify sample changeover and contamination-control procedures.
Proper aseptic technique, bag handling, and laboratory practices remain necessary, particularly for microbiological and cell-culture applications.
Standard, Closure, and Strainer Bags
The Stomacher 80 platform can be used with several styles of disposable processing bags.
Standard bags provide straightforward sample containment. Closure bags can be useful when a sealed or more secure sample format is desirable.
Strainer bags incorporate an internal filtering element that separates larger debris from the resulting suspension, making it easier to pipette liquid after processing.
Bag selection should be based on specimen characteristics and downstream analytical requirements.
Strainer Bags for Samples with Debris
Biological specimens can produce fragments, fat, connective tissue, or other debris during homogenization.
A Stomacher 80 strainer bag incorporates an internal filtering element designed to separate larger particles from the liquid sample.
This can make subsequent pipetting easier and reduce the likelihood that large particles will obstruct a pipette tip.
For laboratories preparing cell suspensions or analytical extracts, this can simplify downstream handling.
Double Strainer Bags and Enhanced Containment
Seward also offers double strainer bags for the Stomacher 80 platform.
These bags were originally developed for applications where additional biological containment was desirable and incorporate a second bag layer for added security against damage or accidental release.
They also include an internal strainer to facilitate recovery of liquid sample.
Appropriate containment procedures should always be determined by the laboratory's biosafety requirements and the material being processed.
Cell Biology Applications
Cell biology laboratories may need to release viable cells from small tissue specimens before culture, counting, staining, flow cytometry, microscopy, or other downstream procedures.
For compatible protocols, the Stomacher 80 provides controlled mechanical processing without exposing tissue to a reusable blade assembly.
The appropriate buffer, processing time, paddle speed, filtration method, and downstream handling procedure should be established experimentally for the particular tissue and cell type.
Microbiology Applications
Microbiology laboratories can use the Stomacher 80 to prepare small specimens for appropriate culture or analytical procedures.
Disposable-bag processing helps isolate one specimen from the next and can reduce cleanup between samples.
The resulting suspension may subsequently be plated, diluted, cultured, filtered, examined microscopically, or analyzed using molecular or other laboratory techniques.
The Stomacher itself does not identify or quantify microorganisms.
Clinical and Biomedical Research
Small-volume tissue preparation is common in biomedical and clinical research.
Research specimens may be limited in size, making it undesirable to use a large-capacity blender requiring substantial diluent volumes.
The Stomacher 80 allows these specimens to be processed on a more appropriate scale.
Its adjustable paddle speed, timed operation, and bag-based workflow also allow laboratories to establish standardized preparation protocols for experimental studies.
Tissue Culture Sample Preparation
For appropriate applications, the Stomacher 80 can be used during preparation of tissue-derived cell suspensions intended for subsequent culture.
Mechanical processing can help separate cells from a tissue matrix before additional filtration, centrifugation, washing, counting, or culture steps.
Whether Stomacher processing is appropriate depends on the tissue type and cell population being recovered.
Laboratories should validate conditions for their specific cell-culture protocol.
Small-Sample Research
Research laboratories frequently work with specimens that are too valuable or limited to justify processing in a large blender.
The 5–80 mL working range makes the Stomacher 80 better suited to small specimens than the much larger Stomacher 400 or Stomacher 3500.
Using an appropriately sized processing system can also reduce unnecessary dilution and simplify recovery of the resulting suspension.
Stomacher 80 vs. Stomacher 400
The Stomacher 80 and Stomacher 400 are designed for different sample-volume ranges and applications.
The Stomacher 80 Biomaster is optimized for approximately 5–80 mL samples and is particularly associated with tissue, clinical, and life science applications.
The Stomacher 400 Circulator handles approximately 80–400 mL and is widely used for food microbiology and general microbiological sample preparation.
A laboratory working primarily with small tissue specimens will generally find the Stomacher 80 better matched to its workflow, while larger food and environmental samples are better suited to the 400 platform.
Stomacher 80 vs. Stomacher 3500
The difference between the Stomacher 80 and Stomacher 3500 is even greater.
The Stomacher 80 is a compact small-sample instrument with an 80 mL maximum recommended capacity.
The Stomacher 3500 is a heavy-duty, large-volume blender capable of processing up to approximately 3.5 liters.
The 80 is therefore suited to small tissue and biological specimens, while the 3500 is intended for bulk food samples, large-volume washing, extraction, powders, and other high-capacity applications.
Stomacher 80 vs. Blade Homogenizer
A conventional blade homogenizer uses rotating cutting surfaces that directly contact the sample.
The Stomacher 80 instead manipulates the specimen through the walls of a disposable bag.
Blade homogenization may provide more aggressive mechanical disruption, but it also introduces reusable sample-contact surfaces and potentially greater shear.
The Stomacher approach can be advantageous when viable cell recovery, disposable sample containment, or rapid changeover between specimens is a priority.
Stomacher 80 vs. Rotor-Stator Homogenizer
Rotor-stator homogenizers use high-speed shear forces to disrupt and homogenize samples.
They are useful for applications requiring aggressive particle-size reduction, emulsification, or cellular disruption.
The Stomacher 80 uses comparatively gentle paddle action and is particularly associated with tissue processing and recovery of viable cells.
Neither technology is universally preferable; the correct choice depends on the specimen and what the laboratory needs to recover from it.
Stomacher 80 vs. microBiomaster
The standard Stomacher 80 Biomaster and Stomacher 80 microBiomaster are closely related but should not be confused.
The standard Biomaster is specified for samples from approximately 5 to 80 mL.
The microBiomaster incorporates an adjustable door system that extends processing capability to much smaller samples, down to approximately 250 µL when used with the appropriate microBag configuration.
Unless an instrument is specifically identified as the microBiomaster version, the standard 5–80 mL specification should be used.
Continuous-Duty Design
Seward specifies the Stomacher 80 for continuous-duty operation.
This allows the blender to support laboratories processing multiple specimens during routine working periods without requiring lengthy scheduled cooling intervals between normal cycles.
Disposable bags also facilitate rapid changeover because a reusable blender vessel does not need to be washed after each specimen.
Together, these features can improve workflow efficiency when multiple biological samples must be processed consecutively.
Compact Benchtop Footprint
The Stomacher 80 measures approximately 290 mm wide × 325 mm deep × 190 mm high, equivalent to roughly 11.4 × 12.8 × 7.5 inches.
At approximately 15 kg, or 33 pounds, it provides a stable benchtop platform while occupying relatively little laboratory space.
The compact footprint makes the instrument easy to position near other sample-preparation equipment or within a dedicated tissue-processing workspace.
Maximum Recommended Sample Temperature
Seward specifies a maximum recommended sample temperature of 60°C.
The Stomacher 80 is a mechanical sample-processing instrument and does not independently regulate sample temperature.
If a laboratory protocol requires specimens to remain chilled, warmed, or otherwise temperature controlled, appropriate conditioning procedures should be incorporated separately.
Sample temperature should remain compatible with the bag, instrument, and intended biological procedure.
