Stomacher 3500

The Stomacher® for blending large volumes

Stomacher® 3500

The high capacity 3500 has been specifically developed for operations that require the blending of large volumes. It has a gentler action than the 80 or 400 models.

  • Blending powders
  • Chocolate
  • Sterility of disposable products: tampons, nappies/diapers


Stomacher® 3500 Biowasher

The 3500 has been designed to accomodate the large volume of cartridge filter fibres and washing solutions in the extraction of water borne parasites such as Cryptospidium and Giardia from filters used to sample large volumes of water. These organisms do not need to be present in large numbers to cause infaction and water samples of 100 litres or more are generally required. the water is filtered and subsequently the organisms are extracted from the filter utilising the Stomacher®'s unique washing action forcing washing solution through the filter fibres. The Stomacher® 3500W is the most efficient and economical approach to this procedure.

  • Cryptosporidium and Giardia testing of water supplies
  • The extraction of organisms or chemical residues from filters or fibres
  • Efficient and economical
  • Forensic applications


Trichinella testing of pork meat is mandatory under EU law. The procedure involves the digestion of samples from different carcases by a combined process of Stomaching, heating and enzymatic digestion, the reulting sediment is examined by microscopy to identify the presence of Trichinalla. The test procedures takes about an hour to complete.

The Stomacher® 3500T has a thermostatically controlled heating panel inside the door designed to maintain the specimen at 40 degrees C temperature. The method is both inexpensive to set up and provides samples for microscopy which are easier to read.

Only genuine Stomacher® bags carry the Seward quality mark 
 

Stomacher 400 Circulator

The Stomacher® for food microbiology

The Stomacher® 400 Circulator is the Worlds leading laboratory blender. When food safety and quality matter the Stomacher can be relied on to safeguard your reputation.

Whatever the microbiological methods you use to enumerate and identify the microbial flora present thorough homogenisation of the sample is the first and most important step.

The unique paddle action extracts more organisms into suspension from a variety of food types than any other blending process. The sample and diluent are retained in an irradiated sterile Stomacher® bag and there is no direct contact between the blender mechanism and the sample.

The Stomacher® 400 Circulator is not only the most effective of its type it is also the quietest and the most reliable.
  • Improved organism recovery
  • One touch user programmable time and speed
  • "Hands-free" auto-run feature
  • Count down of processing time
  • Improved reliabilty and hygenic design

The principle of the Stomacher®

The principle of paddles and Stomacher¨ bags is at the heart of the Stomacher® 400 Circular design. Stomacher® produces homogenisation by a combination of mechanical forces.
  • Crushing
  • Stirring


Both of these are required to maximise organism recovery.

Somacher® 400 Circulator

Curved paddles, an island baffle inside the door chamber and round bottomed Stomacher® bags mould the bag contents into a tubular ring. In operation the paddles not only crush the sample but they also circulate the suspended debris and diluent. This produces additional processing effects.

Only genuine Stomacher® bags carry the Seward quality mark

  • The diluent and sample are extruded under pressure past the island buffer
  • A vigorous stirring action of the bag contents from top to bottom
  • Enhanced shearing forces


The Stomacher® 400 Circular is the most efficient and the most reliable model to date.

Controls and settings

The control panel consists of a touch panel and LCD angled towards the operator.

Timer and paddle speed, essential for consistent results, are now programmable with a combination of the three paddle speeds and anytime from 1 second to 99 minutes 59 seconds.

Stomacher® 400 Circular Bags

Circular bags carry the same guarantee of durability and sterility as the classic bag range. Only genuine Stomacher¨ Bags carry the Seward quality mark.

 

Stomacher 80 Biomaster

The sample processor for the microbiologist, biochemist and cell biologist.

The proven performance of the Stomacher® 80 Biomaster in producing consistent high quality results in a fast and efficient way is well documented. It is in regular use worldwide for the processing of a variety of specimens from sputum, tissue (including lung) and the extraction of chemical and drug residues in biopsy and food samples for analysis.

Used predominantly in clinical, veterinary and life science laboratories, it is quick and clean to operate, requiring no sterilisation between samples. The unique blending action provides a safe hygienic and convenient method for the preparation of samples-eliminating the risk of cross contamination and aerosol production. 
  Improved hygienic design
  Proven reliability
  Biohazard containment
  Enzyme free sputum analysis
  Drug residue
  Tissue


Tissue analysis
The Stomacher® 80 Biomaster is used for processing tissue specimens, single cell suspensions can be prepared in seconds rather than minutes. The Stomacher® 80 Biomaster is unsurpassed at producing large numbers of cells with high viability for tissue culture. Drug residue detection in the food industry has become of increasing importance with new farming practices. The Stomacher® 80 Biomaster offers a rapid and hygeinic means of performing solvent extraction for subsequent analysis.

Sputum Analysis
In the clinical laboratory homogenisation of sputum samples by Stomaching, rather than enzymatic digest is a preferred method. This enzyme free analysis allows bacteriology, immunology and biochemistry to be performed on the same sample, results are significantly faster-1-2 minutes in contrast to half an hour or more.

  • Time saving
  • Enzyme free analysis
  • High Yield of viable cells

Only genuine Stomacher® bags carry the Seward quality mark

The Stomacher® 80 Biomaster is operated by microprocessor controls. It has 3 preset processing speeds and 3 time settings with an additional continuous cycle.

Safe and Hygienic
The Stomacher® 80 Biomaster is the smallest paddle blender in the world, designed to take up less space in the working environment. This unique feature means it will fit inside a safety cabinet, helping to reduce the risk of exposing personnel to infectious or hazardous materials. Samples are retained in the Stomacher® 80 Biomaster bags, these can be heat sealed to remove any further possibility of aerosol release

The Stomacher® 80 Biomaster has a hygienic and durable plastic paint finish to the door, handle and bag clamp.

Stomacher® 80 Biomaster bags and accessories.
The Stomacher® 80 Biomaster has its own range of accessories. A 10 place bag rack for holding samples on the bench, minimising risk of spillage and cross contamination. Stomacher® 80 disposable bags are supplied in packs of 2000 contained in sachets of 50. They are highly durable extruded from high grade polythene and are guaranteed against bursting. Stomacher® 80 Biomaster bags are irradiated sterile.
