Clear answers on isolators, filter bags, sterile LDPE

A flexible isolator is a soft-walled enclosure that creates a controlled environment for product or operator protection. Built from robust film with integrated glove ports and transfer interfaces, it delivers negative or positive pressure containment as needed. Typical uses include potent API handling, aseptic processing, sampling, weighing, and R&D. Compared with rigid systems, flexible isolators install faster, cost less, and adapt to changing processes. We design to your workflow, defining sizes, frames, airflow, and access to optimise ergonomics, throughput, and compliance.

Your isolator can be tailored extensively: choose the number, position, and diameter of glove ports; round or oval rings; butyl, neoprene, or CSM gloves; and sleeve lengths. Specify alpha/beta RTPs, zip doors, continuous liners, pass-throughs, and utility feed-throughs. Transfer and sampling hatches, bespoke frames, pressure control, and HEPA options are available. We model reach envelopes and ergonomics, supply drawings for approval, then manufacture to sign-off, ensuring every port and interface aligns with your process and cleaning regime.

We support compliance end-to-end. Materials are traceable with certificates of conformity and resin data; manufacturing occurs in controlled cleanrooms with documented change control. For sterile LDPE, we provide irradiation certificates and batch records. Flexible isolators can include integrity and pressure-decay checks, with IQ/OQ packs available. Filter bags ship with media specifications, micron ratings, and food-contact declarations if required. On request, we share test data, user guides, and risk assessments to underpin GMP, help qualification, and simplify audits.

Typical lead times for bespoke flexible isolators are two to four weeks from drawing approval, with expedited builds often possible. Standard components and sterile LDPE lines are usually faster. We provide detailed drawings quickly, agree critical dimensions early, and keep you informed at each milestone. Global shipping, export paperwork, and customs support are included. If you need spares or additional gloves, filters, or frames, we stock common items for rapid dispatch and can schedule call-offs for larger programmes.

Our spray dryer filter bags are fabricated from high-temperature, food- and pharma-grade media such as polyester, polypropylene, aramid, or PPS, selected to suit your dryer, product, and cleaning method. Options include antistatic fibres, PTFE membranes, surface finishes, and FDA/EU food-contact declarations. We optimise permeability and micron rating for yield and pressure drop, and design seams, cuffs, and snap-rings for reliable sealing. Bags are compatible with leading OEMs and can be supplied pre-shrunk, numbered, and kitted for efficient changeovers.

We size every bag to your dryer and cage geometry. Provide make and model, bag length, body diameter, cuff style, and hole pattern; we’ll confirm tolerances, seam allowances, and shrink. If drawings are unavailable, we can measure onsite or work from a proven sample. Each set is labelled by position for quick installation, with matching snap-rings or ties supplied. Trial batches help tune micron rating and permeability, protecting yield while controlling differential pressure and facilitating consistent clean-in-place routines.

Sterile LDPE is available as flat bags, gusseted bags, liners, tubing, and equipment covers, in a wide range of gauges and sizes. Items are manufactured in cleanrooms, double-bagged, and gamma sterilised to a validated process, with certificates of irradiation and lot traceability. Options include custom printing, ports, and tear-open features. Typical uses are sterile barrier packaging and aseptic transfers. Shelf-life, compatibility, and extractables data are available on request to support qualification and documentation needs.

Yes. We welcome early engagement and offer low MOQs for prototypes, trials, and pilot runs. Our engineers iterate designs quickly, producing sample isolator panels, glove-port templates, or short runs of filter bags and sterile LDPE packs. We gather feedback from operators, adjust ergonomics or media as needed, and document changes for traceability. When ready, we scale seamlessly to series production, locking specifications, drawings, and QC plans so performance is repeatable and delivery stays predictable.

After each campaign, clean the flexible isolator with approved agents compatible with the film and gloves; avoid abrasives and excessive heat. Inspect seams, zips, gaskets, and filters for wear; replace components showing damage or loss of integrity. Verify pressure or airflow performance before reuse, and record actions in your log. For storage, dry thoroughly, fold to protect windows, seal in a clean bag, and keep in a cool, dark place. We supply spares and maintenance guides.

Our service continues after delivery. You’ll receive installation and operating guidance, troubleshooting support, and access to spares and consumables. Workmanship on manufactured goods is warranted for twelve months; wear parts and media are excluded. Where helpful, we provide operator training, site visits, and documentation updates. If performance needs refining, we analyse data and recommend adjustments or upgrades. Long-term agreements can secure pricing, stock, and scheduled call-offs, ensuring continuity of supply for critical production lines.
