Device will open during centrifugation.

Does anyone know why this is???

Hello, If you can open the EBA 21 during centrifugation, you'll need to replace the lid lock assembly. Depending on whether it is 120v or 220v centrifuge, it will have a different part number. Please contact service@hettweb.com with your TYP number and Werknmr (model number and serial number) so we can help! Thanks! Hettich Instruments Service
