Leica Cryostat Model CM1850 Lacks Fire-Risk Warning for Flammable Sprays

Leica Biosystems is recalling Cryostat Model CM1850 (322 units, US nationwide) due to missing warnings about fire hazard from flammable freezing sprays. The device's labeling prior to 2019 did not warn users that flammable sprays used in the chamber can ignite and cause serious injuries.

What this means for you

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: This is a risk-of-harm medical device where serious injury from fire is possible, but no illnesses or injuries have been reported. The device is FDA Class II with a critical labeling deficiency. Per the severity rubric, risk-of-harm products without reported injuries score at most 3 (High).

Plain-English summary

Leica Biosystems is recalling Cryostat Model CM1850, a laboratory medical device used for freezing and sectioning tissue samples. The recall affects 322 units distributed nationwide in the United States. The device is sold under four material numbers: 14047131148, 14901850001, 14901850001R0501, and 1491850UVUL.

The cryostat labeling prior to 2019 did not include specific warnings about flammable freezing sprays. During post-market surveillance, Leica discovered that some customers were using flammable freezing sprays inside the cryostat chamber. Flammable freezing sprays can ignite within the device, potentially causing serious injuries. Although the spray labels indicate flammability, the cryostat device itself lacked warning about this hazard.
