Vyon® Pipette Tip Filters

Our products

Product category: Filters
Sterile Vents
Our Vyon® porous plastic materials offer excellent properties for venting. Allowing closed environments to breathe whilst maintaining bacterial resistance is highly desirable and a key property in a wide range of medical applications.

Controlled pore size, strength and inertness of our materials are key properties that Porvair Sciences offer our customers. Sterile vents materials are also available as hydrophobic/oleophobic-treated.

Vyon® Pipette Tip Filters
Specifically designed to prevent sample carryover and aerosol bypass, our expertise in porous plastic manufacturing enables us to offer a range of pipette tip filters that are produced with precise specification, optimal air flow and laboratory grade materials that ensure a clean and contaminant-free liquid handling system.

Superior Liquid Handling Properties

Greater optimised airflow for improved pipetting precision and accuracy. Obtain consistent and even target draw volume every time. Perfect for manual and automated pipette systems.

Robust Filters for High Volume Assembly

The inherent strength and hardness of Vyon® pipette tip filters means they are able to withstand up to 70% more compression than conventional porous plastic materials making them ideal for hardwearing automated assembly.

Cut-to-Seal

Manufactured to tight tolerances (+/- 0.1mm) ensures a sealed fit, every time. This prevents fine aerosol passing through the filter into the liquid handling system.

Pure & Clean Materials
Vyon® porous plastics is made from clean* materials and are designed with purity in mind.

Free of Heavy Metal Interference
FDA Approved Raw Materials
USP Class VI Approved
Manufacture with NO release agent

*Internal and 3rd party testing data is available on request.

Vyon® Materials
Designed specifically for use as pipette tip filters, our Vyon® materials are designed to prevent aerosol bypass and any sample carryover. Optimised to be the perfect fit in your tip, our Vyon® porous plastic filters can be manufactured in a wealth of sizes to meet your exact requirements. While our core business is bespoke engineered products, we offer a standard range of pipette tip filters materials. Help cut down on development time and tooling costs by using one of our standard Vyon® materials available in 2.95mm, 3.25mm, 3.55mm & 4mm thickness’.

Product category: Plastics
Deep Well Storage Plates
Deep well polypropylene microplates are commonly used for sample storage in life science laboratories. An essential aspect of the manufacture of these plates is the selection of clean raw materials for injection moulding.

Polypropylene is an inert and heat resistant material, ideal for sample storage. However, all grades of polypropylene are not the same, for example, injection moulding grades of polypropylene often have high concentrations of chemicals to aid the moulding process. This allows rapid production of plates and lower costs, but may compromise the integrity of samples or compounds which are stored in such plates for extended periods. The problem is particularly acute where compounds are stored as solutions in solvents such as methanol or DMSO, as these excellent solvents have a tendency to extract from the polypropylene base material any added extractable compounds such as mould release agents or polymer flow improvers.

Porvair Sciences has published detailed analysis of its own and other manufacturer’s plates, with MS traces, so that you can compare good and bad performers.

Product category: Plastics
Assay Plates
Porvair Sciences have a range of clear polystyrene bottom, glass bottom and solid bottom assay plates that are specifically designed for absorbance, fluorescence, luminescence and scintillation applications.

Porvair Krystal series clear bottom plates are now recognised as industry-leading tools for Pharma drug discovery and screening. Our standard clear polystyrene bottom plates have bases just 0.4mm thick and are moulded from highly polished tools to reduce flow lines, artefacts and scratches, guaranteeing good results with all types of bottom-reading instruments.

For the more modern demanding confocal readers, Porvair Glass Bottom plates have been shown by leading research institutes to be unsurpassed for flatness, linearity and optical clarity. Our sparkling pure borosilicate glass is just 175µm thick with a flatness tolerance across the plate of +/- 15µm ensuring superb crisp images every time.

Product category: Filters, Plastics
Filtration plates
Filtration plates are used in their simplest form to remove particulate matter from liquid. Either the particulate matter or the filtrate is needed for further study.

Porvair Sciences has a range of filter plates to suit most filtration applications. We have optimised filter plates for applications including cell harvesting, DNA separations, binding studies, Plasmid isolation, general filtration and sample clean-up. Porvair has a full range of 48-, 96- and 384-well microplates with a choice of glass fibre, nylon, PVDF or polyethylene filtration materials and well volumes ranging from 350 μl to 5 ml.
