Easy to Use

Use the simple, two-button interface to select a preset, or program and record your validated settings on the included label. Process 75-100 mm (up to 50 mL) tubes in the same holder.

Easy to Monitor

Process samples more efficiently. HORIZON's LED lid lighting is off when the centrifuge is ready to load, on when running, and flashing at the end of each cycle.


Engineered for Safety

Protect your lab with imbalance detection and a shatterproof lid which can only be opened when the centrifuge's rotor is stopped, even if the unit loses power.

Unique Features

The HORIZON 24 Flex is the workhorse of the lab. Designed for flexibility, ease of use, and heavy workloads, it really is the routine centrifuge that can do it all. Process all blood and urine tubes up to 50 mL in size, right out of the box. The digital display makes it easy to program and save up to ten (10) custom settings, or choose from one of three (3) carefully selected presets. LED lid lighting indicates the centrifuge’s status (off when ready, on when running, and flashing when done) to prevent forgotten tubes and preserve sample quality.

What is the warranty on Drucker's centrifuges?
Drucker Diagnostics provides a two (2) year parts and labor warranty (except the rotor - see question below).

What is the warranty on the rotor?
All rotors carry a lifetime warranty. Should the rotor ever fail, for as long as you own your centrifuge, Drucker Diagnostics will replace it free of charge.

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 HORIZON 24 Flex?
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.
