PRODUCT SPECIFICATIONS
Every detail has been specified for pharmaceutical vial filling operations requiring a clean, sterile, traceable closure - delivered in a sealed sterile bag of exactly 1,000 pieces with no additional processing steps required.
Black. Matte. Sterile.
Ready for your filling line.
Black rough matte - no logo, no edge
The rough matte finish is applied to both the plastic flip off disc and the aluminium skirt. No embossing, no debossed logo, no manufacturer mark - a completely clean, unprinted surface. Ideal for compounding pharmacies, research labs, and CDMOs applying their own labels post-crimping.
EO sterilised - SAL 10⁻⁶
Each bag is sterilised by ethylene oxide (EO) to achieve a Sterility Assurance Level of 10⁻⁶ - the pharmaceutical standard. EO penetrates the sealed bag without heat, preserving dimensional integrity while eliminating all microbial contamination.
1,000 pcs in one sealed sterile bag
Exactly 1,000 caps per bag - counted, sealed, and sterilised as a single lot. One bag = one traceable sterile unit, simplifying batch records, inventory management, and incoming QC in regulated environments.
Standard 20 mm crimp compatibility
Dimensioned to the international standard for 20 mm pharmaceutical vial necks - compatible with all rotary, benchtop, and semi-automatic crimping equipment. Forms a hermetic, tamper-evident seal in a single press cycle.
RTU AND RFU - WHAT IT MEANS FOR YOUR OPERATION
open the bag. crimp. done
no preparatory steps. no additional equipment. no added time on your production schedule
RTU - Ready-to-Use
No pre-processing required
No wash cycle. No autoclave. No depyrogenation oven. Open the sealed bag in your clean or aseptic environment and load directly into your crimping system. RTU reduces batch preparation time and eliminates the need for in-house sterilisation equipment.
No washing or rinsing required
No autoclave cycle needed
No depyrogenation oven
Open bag → load crimping equipment → apply
Reduces preparation time and labour cost per batch
RFU - Ready-for-Use
Validated for regulated production
RFU confirms the cap has been manufactured, cleaned, and sterilised to a documented pharmaceutical standard - arriving with the quality attributes required for direct use in GMP pharmaceutical filling and sealing operations.
EO sterilisation to SAL 10⁻⁶
Sterile bag integrity confirmed before despatch
Certificate of Sterilisation (CoS) available
Supports GMP batch record documentation
Simplifies supplier qualification and incoming QC
ETHYLENE OXIDE STERILISATION PROCESS
Why EO - and what it guarantees
Ethylene oxide is the gold-standard sterilisation method for aluminium-plastic pharmaceutical closures that cannot withstand autoclave or dry-heat processing temperatures.
1
Caps are exposed to controlled humidity and elevated temperature to open the material structure, ensuring EO gas penetration reaches all surfaces of every cap within the sealed bag.
2
Ethylene oxide gas penetrates the permeable sterile bag, contacting all cap surfaces. EO alkylates microbial DNA, achieving SAL 10⁻⁶ - less than 1 in 1,000,000 probability of a non-sterile unit.
3
Controlled aeration removes residual EO and by-products to levels compliant with ISO 10993-7 and pharmacopoeial limits - safe for direct pharmaceutical product contact.
4
The 1,000-piece bag maintains sterility until opened. Each bag carries lot number, sterilisation date, and expiry date for full traceability through your supply chain.
5
Sterility and bioburden release documentation confirms cycle performance. Parametric release data available on request, supporting incoming inspection in regulated environments.
6
A CoS or CoC confirming lot number, sterilisation method, SAL, and date is available for every batch - supporting supplier qualification and pharmaceutical batch master file documentation.
WHO USES THESE CAPS
Built for every pharmaceutical filling environment
Ordered by pharmaceutical professionals who need a clean, pre-sterilised closure without the overhead of in-house washing and sterilisation infrastructure.
Hospital & compounding pharmacies
Aseptic compounding · small batch
Preparing sterile injectable preparations - antibiotics, hormones, oncology - without in-house sterilisation equipment. RTU caps integrate directly into aseptic compounding workflows.
Research labs & CROs
Clinical trial material · stability
Producing clinical trial material and stability samples. The 1,000-piece bag matches typical research batch sizes - no over-ordering, no waste, full traceability per lot.
Biotech startups
Pre-clinical · Phase I/II material
Early-stage companies without full sterilisation infrastructure. EO-sterilised RTU/RFU caps enable GMP-compatible production with documentation to support regulatory filings.
Speciality injectable manufacturers
Peptides · cosmetics · growth factors
Manufacturers filling peptide injectables, cosmetic injectables, and growth factor preparations requiring a premium sterile black matte cap without a manufacturer logo.
Veterinary pharmaceutical
Vaccines · injectable preparations
Veterinary vaccine and injectable manufacturers using 20 mm vials benefit from pre-sterilised RTU caps - reducing production steps and improving batch documentation.
Contract fill-finish (CMO/CDMO)
Sterile fill · multi-client
CDMOs stocking RTU components for multiple client products. The 1,000-piece bag provides lot-level inventory with sterility documentation for client batch records
Handling & storage - maintaining sterility integrity
Store in the original sealed sterile bag at 15–25 °C, away from UV light and moisture. Do not open until ready for use in a clean or aseptic environment. Check bag integrity on receipt - do not use if the seal is compromised. Once opened, use the full bag contents within the filling session. Shelf life and expiry as indicated on bag label.
