Syringe filters are a consumable. They get used once and binned. So why are labs still paying £3 to £4 each?
Because they're buried on page 47 of a catalogue order alongside everything else, and nobody's ever been asked to justify the line item. Filters go on the order. The brand is whatever got specified five years ago when the method was written, and procurement re-orders it because it's what was ordered last time.
That cycle costs labs thousands of pounds a year on a single consumable.

What you're actually paying for
A syringe filter is a polypropylene housing, a membrane disc, and a seal. The membrane chemistry (PES, nylon, PTFE) is the same regardless of whose name is on the housing. Pore size ratings are standardised. The housing geometry is standardised. This is not a precision instrument with proprietary IP. It is a disposable filtration device.
The price difference between a £1.30 filter and a £3.50 filter is not a quality difference. It's a distribution model difference. Big brands sell through distributors, who sell through frameworks that add margin at every layer. Specialists like us buy direct, stock deep, and sell at prices that reflect what the product actually costs to make.
The numbers on one product
Our PES 0.45µm syringe filter with 5µm PP pre-filter, 33mm, 500-pack: £650.00.
That's £1.30 per filter.
A comparable pre-filtered PES syringe filter from a major catalogue supplier will run you between £2.50 and £4.00 per unit depending on the brand and the framework you're buying through.
A lab that uses 100 syringe filters a week, which is modest for any environmental, QC or analytical lab, spends:
- At £1.30/filter: £6,760/year
- At £3.00/filter: £15,600/year
- At £4.00/filter: £20,800/year
That's £8,800 to £14,000 per year on a single consumable line, freed up by changing supplier. Not by changing the product. Not by compromising on spec. By buying the same thing from someone who prices it sensibly.
"But our method specifies Brand X"
Methods specify membrane type, pore size, diameter and sometimes extractable levels. They do not specify a brand, and if yours does, it shouldn't. A PES 0.45µm 33mm syringe filter with a PP pre-filter is a PES 0.45µm 33mm syringe filter with a PP pre-filter. The membrane performs to the pore rating. The housing holds it in place. That is the entire job.
If your QA team wants validation data, request a free sample and run it alongside your current filter. The results will be identical, because the specification is identical.
High stock, immediate dispatch
We're currently carrying high stock on this line. Order today, it ships today. No lead times, no backorder emails, no scrambling for alternatives because the distributor's warehouse is empty.
For a consumable you use every day, supply reliability matters as much as price. We stock deep on the lines labs use most, because running out of syringe filters shouldn't happen.
High-quality consumables at unrivalled prices. The home of chromatography consumables, and so much more.
