A biological indicator (100) for use in a liquid-chemical decontamination system is disclosed. The biological indicator may include a housing (102) and a cap (106) coupled to the housing. The cap may comprise a liquid chamber and at least two ports. One of the ports may connect to a liquid passage in the cap such that liquids such as liquid-chemical decontaminants may be introduced and removed from the biological indicator via this port.

The present disclosure relates to a consumable sample partition device and it assembly and use. The sample partition device can be used to test a sample for absence of microorganisms (sterility) and/or for concentration of said organisms (bio-burden). The sample partition device partitions the sample input volume into multiple discrete measurement zones with little or no loss of sample (e.g., zero-loss) and with little operator involvement, thereby reducing operator- and environment-based false positives.

A system that enables automatic biological indicator crushing and determination of biological indicator type and model in incubator devices with biological indicator readers.

A method for an automatic inspection of a plurality of plate-like plastic carriers, whereby each plastic carrier is closed by a cover and has a unique identification code and a culture medium. A storage container including a multiplicity of plastic carriers is provided, and a computer-controlled handling unit including an optical inspection system is provided. While performing the automatic inspection in an inspection routine, a plastic carrier is removed from the storage container with the aid of the handling unit, the cover of the plastic carrier is subsequently removed, the plastic carrier is supplied to the inspection system, the identification code is read, and at least one image of the plastic carrier, including the surface of the culture solution is recorded. The image is evaluated for a growth of germs and/or faults in the plastic carrier and the result of the evaluation is stored for each plastic carrier.

A reference test body for monitoring and/or verifying test conditions during a test of microbial barrier properties of at least one product, wherein the reference test body has a cavity, a nutrient medium, at least one opening, and at least one cover provided with a number of holes and covering the at least one opening. A constancy of test conditions can be monitored in this way. The invention further relates to an associated use, an associated test chamber, and an associated method.

Inoculating systems/devices, methods for inoculating a target, and coating methods are disclosed. An example inoculating system may include an inoculating member having a transfer region and a handle region. A pre-determined quantity of viable microorganisms may be disposed on the transfer region. The inoculating member may be configured to transfer the pre-determined quantity of viable microorganisms to a target during an inoculation operation without having to rehydrate the pre-determined quantity of viable microorganisms prior to the inoculating operation.

An article is provided. The article comprises a nonwoven substrate having a copolymer grafted thereto, and a dried coating adhered to the substrate. The copolymer comprises interpolymerized monomer units of a quaternary ammonium-containing ligand monomer, an amide monomer, and an oxy monomer. The coating comprises a plurality of test microorganisms. Optionally, the coating further comprises a water-soluble or water-dispersible polymeric binding agent. A process challenge device comprising a body having a hollow channel with said article fixed disposed therein is also provided. Methods of using the article or the process challenge device for determining the efficacy of a disinfection process are also provided.

Provided is a technique for suppressing false positives due to environmental contamination and easily performing a highly sensitive and highly accurate microbial test. A filtration cartridge according to the present disclosure includes a filter cup with a filter capturing microorganisms, a first filter cup attachment that covers a lower portion of the filter sup and at least one through-hole in a bottom surface portion, and a second filter cup attachment, being connected to the first filter cup attachment, that covers an upper portion of the filter cup, and that has a lid installed at a position away from an opening surface of the filter cup.
