The Model 642B Centrifuge uses a mechanical timer for controlling the cycle time and the lid is non-locking.

What is the warranty on Drucker’s centrifuges?
Drucker Diagnostics provides a two (2) year parts and labor warranty.

Will I need to purchase accessories for the centrifuge separately?
All of our centrifuges are sold complete with the rotor and tube holders. No additional accessories are necessary though there are additional options available for purchase.

How often should my centrifuge be calibrated?
Drucker Diagnostics recommends the centrifuge be calibrated every 2 years or 5,000 cycles.

What should be used to clean and disinfect the Model 642B?
ONLY isopropyl alcohol, soap and water, or a 10% (5,500 PPM) bleach solution should be used for cleaning and disinfection of the centrifuge and accessories. All surfaces must be dried immediately after cleaning and disinfecting.

What cleaning solutions should be avoided?
TBQ Germicidal products should not be used as they will cause damage to the centrifuge and void the warranty. The use of fully/partially halogenated hydrocarbons, ketones, esters, ethers, benzyls, ethyl benzenes, and all other chemicals not prescribed by Drucker Diagnostics should not be used as they may cause damage to the rotor chamber, rotor, tube holders, accessories, and centrifuge exterior. If this occurs the warranty will be voided.
