The voluntary service offering has been initiated due to a report that the chamber lids of certain
TOMY MX-Series High Speed Refrigerated Micro Centrifuges and TOMY MicroTwin
Refriegrated Tabletop Micro Centrifuge may accidentally open while in use if the rotor rack is
not installed into the rotor properly.
Proper installation of the rotor rack is essential to maintaining the balance in the centrifuge
while it is spinning. Failure to install the rotor rack properly may cause the rotor rack to come
off the rotor, and the force created by the rotor rack coming off the rotor while the centrifuge
is in use may result in the locked centrifuge lid bursting open. This may create a dangerous
situation for the person operating the centrifuge.
To improve safety, TOMY has decided to send service personnel to users’ facilities to update
the lid lock unit of the above-listed centrifuge models. Further, for Centrifuge Model MX-300
120V Nos. from 36080001 to 39080020 and MX-301 120V Nos. from 39325001 to 40325010,
TOMY will also install an additional safety adapter in the lid that covers the rotor.
This service will take approximately thirty (30) minutes and will be offered at no cost to users
who register for the update.
To register for this update, please fill out the following Service Acknowledgment form.
