Spore discs, Sportrol™

Supplier: CROSSTEX

Biological sterilisation discs are used to perform sterilisation cycle validation in small areas of a device, where a standard-sized spore strip will not fit, such as within a syringe barrel, inside tubing, or under a cap. Spore discs are created by inoculating spore suspensions of certified population and resistance onto paper discs.

VWR® SD 820, Chemistry Diaphragm Vacuum Pumps, Self-drying for Moist Gases

Supplier: VWR Collection

Dual-head, dry running diaphragm pump with an integrated self-drying system. There is a wide range of applications for this pump in laboratories, especially whenever clean vacuum is required and moist gases must be pumped down. Examples include operation of vacuum drying chambers (for drying or heat-treating substances and components) or steam sterilisers for sterilising instruments, vessels, filters and textiles. This pump can be used in a wide range of applications due to the pump's high resistance to aggressive media. The pump includes a PTFE coated diaphragm with patented tension optimisation, which allows the pump to be smaller, and prolongs the service life of the diaphragm. The innovative self-drying system allows condensed liquid to be blown out of the pump heads at high speed during evacuation. The vacuum in the vacuum chamber remains constant. The drying cycle can be adjusted to the requirements of the individual process using three variables. After drying, the pump reaches a better vacuum and is able to evacuate significantly faster compared with pumps without a drying system.

Spore suspensions, Sportrol™

Supplier: CROSSTEX

Spore suspensions are pure suspensions of viable spores from specific organisms of known resistance to various sterilisation processes. These biological indicators are used to validate that bacterial spores have been completely destroyed. The indicator is simply processed with the load in the steriliser. No bacterial growth after culturing indicates that the sterilisation process is effective. Growth indicates ineffective sterilisation.

Silica gel, granulated 1 - 3 mm drying agent, with moisture indicator (orange gel), Supelco®

Supplier: Merck

Desiccant suitable for desiccators to remove water, and for drying most gases and liquids (apart from strongly acidic and basic gases, organic solvents or alkaline liquids). The product contains iron salts as the indicator. Colour change is from orange to colourless at approx. 7/10 g adsorbed H₂O/100 g silica gel. Regeneration can be performed as often as required at 130 to 140 °C in a drying oven for approx. 3 hours.
