Gas Filtration - 0.2 um Hydrophobic PTFE

Our Helapet ISOVent® 0.2 micron hydrophobic filtration devices deliver superior filtration capabilities and are used in a wide variety of applications.  A frequent application is the prevention of water and vapour penetration, thus providing equipment with protection from moisture.  ISOVent® 0.2 micron filters are used for the sterile venting of vessels and containers and for purifying air for gas detection applications.  Helapet ISOVent® 0.2 micron hydrophobic filtration devices are manufactured on site, where we utilise up to the minute ultrasonic technology.  The Helapet filtration devices are fully tested and validated to ensure the highest quality and effectiveness.  Please feel free to contact us for more information and free samples.  Note that we can also supply bespoke design products to suit your specific needs.

Gas Filtration - HEPA

Helapet ISOVent® HEPA (High Efficiency Particulate Air) filtration devices are used in many different industries to ensure effective and reliable filtration of gas and air.  Our range is available in 25mm and 50mm devices, with a selection of barb connectors so you can find the solution that best suits your particular requirements.  We can also provide bespoke devices as needed.  The HPEA media used has a 99.97% efficiency rating and conforms to ISO 13485:2003 standards.  Our filtration devices are fully tested and validated using up to the minute testing techniques.  You can see more about Helapet ISOVent® HEPA devices on our website.

Pipette Filters for Aseptic Transfer

We supply a range of pipette filters for aseptic transfer.  We have designed these filters to provide a universal fit for pipettos, used in cleanroom environments.   Hydrophobic membranes allow sterile air to enter the pipette when fluids are transferred between containers, thus avoiding contamination and preventing water from entering the instrument.  You can be assured of an effective high quality product to ISO 13485 standards.  All our filters are tested on site.  See our website for more information or get in touch and we will be happy to answer your queries.

ISOVent® 50 mm and 25mm Filters

At Helapet we have drawn on our considerable experience and experience to design standard filters which use our innovative ISOVent® technology.  There are two sizes available – 50mm and 25mm.  There are several ISOVent® filters for various functions, including separating airborne particulates from gas/air, non-sterile hydrophobic venting to allow for increased airflow, sterile hydrophobic venting of gas and absolute screen filter to filter particulates in liquid.  As experts in the field of filtration, we are pleased to offer advice on the newest technologies.  Further, we provide a bespoke design and manufacturing service, selecting the optimum media and housing materials for your specific application.  You can see much more information and detail about ISOVent® filters on our website, so do take a look.

Ink-Jet Filters

The printing industry demands quality precision parts and requires ink jet filters that provide superlative flow rates and particle retention.  Our ink jet filters fill this requirement admirably and effectively regulate the timing and levels of ink flow delivery.  We comply fully with the ISO 13485 standard for quality in manufacturing.  Further, we carry out stringent housing integrity and flow rates to ensure optimum performance.  We also offer full testing and quality control facilities at our manufacturing site in Bedfordshire.  You can contact our knowledgeable sales team for more information and to learn about our on site bespoke design and manufacturing service, as well as personalised branding.

Latest Technology - Security and Integrity

We make use of the very latest technologies to ensure that our customers benefit from high quality, effective and trouble-free filter products.  We understand that reliable quality is essential to fight the ever-present risk of chemical or particulate contamination.  We manufacture our filters using statistical process controls to very strict standards in a controlled clean environment.  We employ chemical-free ultrasonic welding, using acoustic vibrations bonding media and polymers, producing a hermetic seal to avoid any possible bypass.  We go the extra mile to ensure our customers have the reliability, effectiveness and, above all, security that is vital.  You can see much more about all the up-to-the-minute technologies we employ by visiting our website.
