Terminated: 2012-12-11
Recalling firm: Carl Zeiss Microscopy, LLC
Product: DirectFRAP (Direct Flourescence Recovery After Photobleaching) Imaging System is an extension unit for Axio Observer that is used for microscopic analyses of dynamic processes within living cells. The DirectFRAP module is a component used in conjunction with Laser Scanning Microscopes, Non-Medical Devices for Research Use. The DirectFRAP Imaging System is a Class 3B laser system. The DirectFRAP Imaging System is a laser manipulation slider which allows coupling of laser light simultaneously with the conventional fluorescence illumination into the reflected-light beam path of the microscope system. Depending on the application, the laser light is used for the targeted bleaching of fluorophores for FRAP experiments or for the conversion of fluorophores within the cell.
Product code: REK Research Laser
Reason for recall: The manufacturer confirmed that the opto-semiconductor sensors can be triggered by exposure to incandescent lighting. The safety interlock is in place to prevent unintended exposure to Class 3B laser radiation.
Root cause tag: manufacturing process
FDA root cause: Nonconforming Material/Component

About this record

Sourced from the FDA device recall database and the FDA enforcement reports, both ingested from openFDA. The recall record supplies the product, the reason and the product code; the enforcement report supplies the classification. The two datasets are exported by FDA on different days, and the date above is the older of the two, so nothing on this page is newer than it says.

MDM adds the root cause tag, derived from FDA’s own root cause text, and the cross-links to the product code, the clearances named on the record and MDM coverage. Where a recall has not been joined to an enforcement report, no classification is shown.
