Leica Biosystems recalls CM1900 cryostats with specific material numbers due to risk of serious injury from flammable freezing sprays used in chamber. Check serial numbers for affected units.
As part of our post market surveillance, we recognized that some customers are using flammable freezing sprays within the cryostat chamber. All flammable freezing sprays can potentially ignite and therefore can cause serious injuries. The flammability is indicated on the labelling of these sprays. The cryostat labelling, however, did not include any specific warning about usage of flammable freezing sprays prior to 2019.
Leica Biosystems is recalling CM1900 cryostats that may have been used with flammable freezing sprays. This poses a serious injury risk if the sprays ignite inside the chamber, which can happen if the cryostat label didn't warn about this before 2019.
The cryostat chamber can ignite flammable freezing sprays if they are used inside, potentially causing serious injuries. The label did not warn about this risk before 2019, so users might not have known to avoid it.
