Stomacher® 3500 Jumbo Strainer Bag

Seward

Price not listed

The Stomacher® 3500 Jumbo Strainer Bag is ideal for large volume blending. It is suitable for samples that produce a large amount of debris or fat as well as microbiome production or harder samples such as shellfish. They contain a robust strainer element to make it easier to pipette the sample produced (pore size 0.5mm, prevents pore blockage and non-homogenous sample). Manufactured to industrial standards, the bags are regularly used for applications in microbiome, food microbiology, forensic residue analysis and testing for waterborne parasites. Sample size 400ml – 4500ml Integrated straine

Buy from SEWARD LIMITEDSEWARD LIMITED is a UK retailer, not the maker. Price seen 2026-09-26. Not an affiliate link, we earn nothing from it.

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as SEWARD LIMITED, number 03211467. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
Not yet checked.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
Not established. Many companies file a statement rather than naming a controlling shareholder.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
