Laboratory sterilisation: how can sterile packaging and traceability be secured?

In a demanding laboratory, sterility is non-negotiable. Our sterilisation consumables and accessories deliver a dependable sterile barrier and seamless traceability, from packaging through to batch release. Pouches and sterilisation tubing, wrap sheets (nonwoven), chemical and biological indicators, perforated trays and containers, bowl covers… every component is engineered for steam, EO, H?O? or dry-heat cycles. Compliant with key standards, they protect your instruments, glassware and culture media while optimising sterilant penetration, drying and storage.

What are the main sterilisation consumables and accessories?

To ensure reliable sterilisation by steam, EO, H?O? or dry heat, selecting the right packaging and sterilisation indicators is critical.

• Sterilisation pouches and reels: medical-grade paper + transparent film, printed external indicators, easy-open chevron. Reels (rolls) cut to length; pouches suit standard formats. Criteria: process compatibility, usable width, seal quality, peelability and post-cycle integrity.

• Sterilisation wraps (nonwoven sheets): SMS-type nonwovens, high wet/dry strength, low lint, excellent porosity. Single or double wrapping for instrument trays, set trays and bulky loads.

• Sterilisation indicators: chemical (to ISO 11140, classes 1 to 6) to evidence exposure; multi-parameter types to place at the load centre. Biological indicators (ISO 11138) verify the microbicidal effectiveness of the sterilisation cycle performed.

• Sterilisation trays and containers: stainless steel/anodised, optimised perforations, lids, silicone mats. Promote steam circulation and drainage and protect delicate parts. Reusable, robust, traceable (engraving, labels).

• Bowl covers for sterilisation: autoclavable nonwoven bowl covers that let the agent pass while preserving the sterile barrier after the cycle and during storage and handling.

Cross-cutting selection criteria: load type, process, porosity, mechanical strength, sealability, particulate cleanliness, cleanroom manufacturing, batch traceability and compliance with EN ISO 11607 / EN 868.

Type	Principle	Applications
Pouches / reels	Sealed paper–film with external indicator	Single items, glassware, small instruments
Wraps (sheets)	Breathable nonwoven, single/double wrapping	Sets, instrument trays, mixed loads
Chemical indicators	Process-sensitive inks (ISO 11140)	External/internal exposure control
Biological indicators	Spore test (ISO 11138)	Qualification, periodic monitoring
Trays / containers	Perforated support	Organisation, protection, optimal drying

In which application areas are these sterilisation consumables used?

• Life sciences and microbiology: sterilising glassware, media, instruments and filters prior to aseptic processing.
• Pharmaceutical/biotechnology: preparing tooling and non-critical components; routine monitoring with biological indicators for documented release.
• Food & beverage: microbiological testing, validation of cleaning procedures, risk control in QC laboratories.
• Cosmetics: sampling, challenge tests, preparation of sterile tools.
• Chemistry/environment: sterility of containers and accessories before sensitive sampling/measurements.
• Education/R&D: steam cycles at 121–134 °C; packaging and indicators to track and standardise practice.
Post-cycle storage in a clean, dry area to preserve the sterile barrier.

Frequently asked questions about laboratory sterilisation

How to choose between sterilisation pouches and reels?
Pouches suit fixed formats; reels let you cut to length. Check the process (steam/EO/H?O?), usable width, seal quality, printed indicators and clean peelability.

Where should chemical and biological indicators go?
An external indicator on the pack, and a multi-parameter at the most difficult-to-sterilise point. Routine tests (e.g. air removal/Bowie-Dick) and biologicals follow your quality policy.

Do sterile packs have an expiry date?
Yes—the pre-sterilisation shelf-life is typically 2 to 5 years, usually set by the lifespan of the printed or adhesive indicator on the pack. Also store in a clean, dry place. Check integrity and the indicator. Follow your internal shelf-life if required by your quality system.

Can sterilisation pouches be reused?
No—single use only (risk of micro-perforations and seal failure). To cut waste, prefer reusable trays/containers where the process allows.

Which standards govern these products and checks?
EN ISO 11607 / EN 868 for packaging, ISO 11140 for chemical indicators, ISO 11138 for biologicals. Require batch traceability and certificates.

How to load an autoclave correctly with these packs?
Do not overload; let steam circulate. Face paper to film, avoid water pockets, and set adequate drying to prevent wet packs and maintain the sterile barrier.
