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

An object of the present invention is to provide a novel method for diagnosing film degradation which can identify the degraded state of a film based on a resin more efficiently and reliably than ever. In order to attain this object, a method for diagnosing the degradation of a film based on a resin is adopted, the method comprising using the following analysis method A and/or analysis method B, which is a non-destructive analysis method: analysis method A: confirming the presence or absence of abnormality in the film by visual observation and olfactometry, and analysis method B: confirming the presence or absence of an acid anhydride and a sign of hydrolysis reaction as to the film by Fourier transform infrared spectroscopy analysis.

Provided is a reaction apparatus for comprehensively measuring biodegradability of a material, comprising a device frame, an electrical control cabinet and a reaction chamber monomer. The upper side of the reaction chamber monomer is a reaction chamber body, and the lower part is a material receiving trolley. The top of the reaction chamber body is sealed by a chamber cover. A side wall is pasted with an electric heating plate and a thermal insulation cotton. A stirring paddle is arranged inside. An air inlet and an air outlet are respectively provided on a front and a rear wall. A discharging mechanism is located below. The electrical control cabinet separately controls the reaction conditions of each reaction chamber monomer. The present invention further relates to a use method thereof, which can realize the biodegradability evaluation in such three aspects as material degradation rate, disintegration rate and ecological non-toxicity test.

An OH radical measurement device includes a contact unit configured to bring an OH radical detection probe into contact with a gas to be measured, the OH radical detection probe including an aromatic carboxylic acid or an aromatic carboxylic acid derivative, a polar aprotic organic solvent, and a polar protic organic solvent having a content higher than a content of the polar aprotic organic solvent.

The present disclosure relates to a kit and method for testing harmful heavy metals onsite, which can determine the presence or absence of harmful heavy metals and the degree of contamination with harmful heavy metals dissolved in water or contained in sediment, soil, deep-sea mining tailings and the like. The kit includes a receiving member and a diagnostic solution containing a biosurfactant, which is accommodated in the receiving member and undergoes an ion exchange reaction with a liquid including harmful heavy metals or a solid sample from which harmful heavy metals are leached in a liquid phase.
