SteriGo™ Self-Contained Biological Indicators (SCBI)

Spores, carrier, and growth medium integrated into a single protective vial for routine monitoring and absolute validation of steam and hydrogen peroxide sterilization cycles. A negative result ensures that the chosen micro-organism has been completely destroyed.

Steam Sterilization SCBI: Utilizes Geobacillus stearothermophilus (Cell Line 7953) with standard spore populations available in certified 10⁵ and 10⁶ arrays. Delivers a reduced, rapid minimum incubation timeline of 24 hours alongside a stable 2-year shelf life.
Hydrogen Peroxide (VH₂O₂) SCBI: Engineered explicitly for monitoring low-temperature gaseous hydrogen peroxide sterilizer processing loops, running a fast 24-hour incubation at a certified 10⁶ population level.

Catalog: MSCS-05E MSCS-06E (steam) · MSCH-06E (VH₂O₂)

SporeGo™ Spore Ampoules (For Liquid Load Validations)

Sealed 1 mL glass spore ampoules optimized specifically for validating the complete thermal sterilization of liquid loads, eliminating manual handling errors or sample cross-contamination.

Traceability Parameters: Packed with Geobacillus stearothermophilus (Cell Line 7953) at certified 10⁵ or 10⁶ population variants. Supplied 50 ampoules per box with a 2-year shelf life, alongside matching 1 mL negative controls (10 per box) for a clean baseline.

Catalog: SA1-50-05E SA1-50-06E · Negative control SA1-NC-10E

Bowie-Dick Test Packs (For Air-Removal Performance Check)

Single-use, non-hazardous daily performance check designed to confirm absolute pre-vacuum air removal and uniform steam penetration inside dynamic air removal steam sterilizers. Run in an empty chamber, it is ideal for routine checks, new installations, and post-repair validation.

Visual Verification & Standards: Conforms strictly to EN 867-4 and ISO 11140-1 (Class 2) parameters. Features a specialized central chemical indicator sheet that delivers a sharp, unmistakable Blue-to-Pink pass color shift upon cycle success. Manufactured completely free from toxic lead or tracking heavy metals with a long 5-year shelf life.

→Pass: Blue to Pink

Catalog: BD-1XECS · 20 packs per case · run at 134°C for 3.5 min or 121°C for 15 min

HyperGo™ VHP Spore Discs

Premium 6 mm structural steel spore discs individually packed in breathable Tyvek®-to-Tyvek® shielding. Engineered to be distributed across sterile cleanrooms, pharmaceutical isolators, and manufacturing enclosures to prove true bio-decontamination lethality during Vaporised Hydrogen Peroxide decontamination cycles.

Target Strain Array: Available across calibrated 10⁴ and 10⁶ populations utilizing specialized Geobacillus stearothermophilus strains ATCC 12980 or ATCC 7953 to match specific validation parameters. 1-year shelf life. Code key: HPG + strain (129 = ATCC 12980, 795 = ATCC 7953) + population (06 = 10⁶, 04 = 10⁴).
