Product range & specifications
Four lines, produced to order. Where a standard size exists we use it — it shortens lead time and keeps tooling cost off your invoice. Where it doesn't, we tool to your drawing.
Single-use PE medicine bags
Flexible polyethylene bags for liquid handling, intermediate storage, sampling and transfer. Built from virgin LDPE or LLDPE with no slip additives, so the contact surface stays clean and the weld stays strong.
Standard configurations
| Volume | Nominal dimensions | Film thickness | Typical use |
|---|---|---|---|
| 0.5 L | 150 × 200 mm | 0.08 mm | Sampling, small aliquots |
| 1 L | 180 × 250 mm | 0.08 mm | Sampling, QC retention |
| 2 L | 220 × 300 mm | 0.10 mm | Buffer and media hold |
| 5 L | 300 × 380 mm | 0.10 mm | Process intermediate |
| 10 L | 380 × 480 mm | 0.12 mm | Bulk liquid transfer |
| 20 L | 450 × 600 mm | 0.12 mm | Media preparation |
| 50 L | 600 × 800 mm | 0.15 mm | Bulk hold, single-use mixing |
Custom dimensions are the norm, not the exception — send us the volume and footprint you need and we will confirm the film gauge.
Fitments & connections
- Standard spout with screw cap, welded to the bag face or top seam
- Luer-lock and luer-slip ports for syringe access
- Needle-free / needleless access valves
- Dip tubes in cut-to-length or floating configuration
- Aseptic connectors and sterile weldable tubing where a closed system is required
- Hanging loops, grommets or welded tabs for rack and bag-holder mounting
Sterilisation & presentation
Reagent bottles & lab containers
Rigid containers for reagents, buffers, media, stains and samples. The resin is chosen for chemical compatibility first, appearance second — a bottle that yellows is annoying; a bottle that leaches is a recall.
| Material | Clarity | Chemical resistance | Best suited to |
|---|---|---|---|
| HDPE | Opaque | Excellent — broad range | Aqueous reagents, buffers, general lab use |
| PP | Translucent | Very good, autoclavable | Media, solutions requiring sterilisation |
| PET | Clear | Good — avoid strong alkali | Visual inspection, display, diagnostics |
| PS | Clear, rigid | Moderate | Dry reagents, specimen containers |
| LDPE | Squeezable | Excellent | Drop-dispense bottles, wash bottles |
Standard capacities
30 mL, 60 mL, 125 mL, 250 mL, 500 mL, 1,000 mL and 2,000 mL in narrow-mouth and wide-mouth formats. Square and round profiles. Amber and light-blocking options for photosensitive reagents.
Closures
- Screw caps with PE or PTFE-faced liners — 24-410, 28-410, 38-400, 53-400 and other standard necks
- Flip-top dispensing caps and push-pull closures
- Vented caps for media and gas exchange
- Dropper and dropper-tip inserts
- Tamper-evident ring and induction-seal liners where traceability matters
Chemical compatibility check. Tell us the reagent, the concentration and the storage temperature. We will confirm the resin and the liner material before quoting, and put the recommendation in writing.
Sampling & biohazard bags
Bags that leave the lab. Printed, closable, autoclavable and — where the application requires it — labelled to UN3373 Category B transport requirements with the correct pictogram and 95 kPa pressure wording.
| Type | Closure | Thickness | Application |
|---|---|---|---|
| Stand-up sampling bag | Wire or zip | 0.05–0.09 mm | Liquid and powder sampling, homogenisation |
| Flat sampling bag | Zip or heat-seal | 0.05–0.08 mm | General sample transport |
| Biohazard transport bag | Zip + document pouch | 0.05 mm | Specimen transport, UN3373 marking |
| Autoclave bag | Twist-tie or heat-seal | 0.05–0.08 mm | Decontamination at 121 °C |
| Sterile sampling bag | Zip or tear-top | 0.07 mm | Microbiology, gamma sterilised |
Printing & marking
- Up to four colours, flexo or digital, registered to your artwork
- Biohazard and UN3373 pictograms
- Write-on white panel for sample ID
- Barcodes, QR codes and lot numbering
- Multi-language transport wording
A note on transport claims. Marking a bag with UN3373 wording does not by itself certify a packaging for Category B transport. That depends on the complete package and your own validation. We supply bags built to the P650 performance requirements and will document the test data we hold — but final compliance stays with the shipper. We will say so in writing rather than let you assume otherwise.
Custom & private label
For distributors and established brands: your artwork, your part numbers, your packaging format — produced under your name and shipped without any Fortuna branding unless you ask for it.
Artwork & branding
Pantone matching, multi-colour flexo, barcode and lot marking, instructions for use printed or supplied as a loose insert. Print proofs approved before the run starts.
Tooling & dimensions
New moulds and forming tools from your drawing, a competitor sample, or just the target volume and footprint. Tooling cost is quoted separately and stated up front.
Packing formats
Bulk cartons, cleanroom double-bagged, individually bagged sterile units, kitted procedure packs with your components and ours combined in one sterile presentation.
Regulatory file
Technical file support for your own registration: material declarations, test reports, process descriptions and change-control commitments written for a notified body or FDA reviewer.
Lead times
Standard sizes: 25–30 days after artwork approval. New tooling: add 20–35 days for mould manufacture and first-article approval. We quote the realistic date, not the attractive one.
Exclusivity
For volume commitments we will agree product exclusivity in a named territory, in writing, so your private-label line is not sold out from under you.
What we can put in your file
Ask for any of the following at quotation stage — we will confirm which we hold for the specific grade before you order.
| Document | Scope | Issued |
|---|---|---|
| Certificate of Analysis | Dimensional check, seal strength, visual inspection against the agreed specification | Per lot |
| Material declaration | Resin grade, supplier, additives, absence of slip and antiblock agents where specified | Per order |
| USP <661> statement | Physico-chemical testing of the contact material | Per material, on file |
| USP <87> / <88> (Class VI) | Biological reactivity and implantation testing | Per material, on file |
| EU 10/2011 declaration | Plastic food-contact compliance, including migration data | Per material |
| FDA 21 CFR 177 statement | Indirect food additive / olefin polymer compliance | Per material |
| Irradiation certificate | Dose mapping, minimum and maximum dose, dosimeter records | Per sterilisation lot |
| Sterility assurance statement | SAL 10⁻⁶ claim basis and validation reference | Per sterilisation lot |
| Change control notice | Notification of any resin, supplier or process change before shipment | On change |
Availability depends on the material and the manufacturing site. Where a document is not held, we will say so at quotation rather than after the order.
Not sure which line fits your application?
Describe the use case — what goes in it, at what temperature, and how it is handled — and we will point you at the right product and resin, even if that means telling you we are not the best supplier for it.
