Why Choose a Used Beckman Optima XL Ultracentrifuge?

The Optima XL series stands out for labs that need continuous-flow operation and precision control. Whether you're running plasmid preps, gradient fractionation or virus purification protocols, this series offers repeatable separations without the premium price of new equipment. Our technicians test each unit before shipping, and we respond to inquiries within one business day.

Beckman Optima XL Floor Ultracentrifuge Features

The Beckman Optima XL-80K, XL-90K and XL-100K ultracentrifuges combine robust engineering with intelligent software controls:

• High-speed capabilities across three models: The XL-80K reaches 80,000 rpm, the XL-90K hits 90,000 rpm and the XL-100K peaks at 100,000 rpm. Maximum RCF reaches 802,000 x g with compatible rotors, providing the force needed for isolating small particles and separating components by density.
• Energy-efficient thermoelectric temperature control: The Optima XL uses solid-state thermoelectric heating and cooling rather than Freon-based refrigeration. This design reduces environmental impact and simplifies maintenance. Temperature control operates from 0°C to 40°C in 1°C increments.
• Interactive menu-driven operation: Microprocessor control streamlines setup and execution. The menu system stores frequently used protocols in a nine-program library and supports multistep sequential runs. A built-in printer outputs rotor usage logs and run data.
• Efficient sedimentation program (ESP) support: The ESP feature simulates gradient formation and sample separation across a wide selection of Beckman Coulter rotors.
• Safety and protection systems: The imbalance-tolerant drive helps protect against operator errors when loading tubes. If the rotor energy calculation identifies excessive force, the system recalculates and uses a safer set speed. An overspeed disk in each rotor verifies that maximum-rated speeds are not exceeded.
• Vacuum system with purge capability: A mechanical vacuum pump paired with a diffusion pump reduces chamber pressure to minimize friction and heat. The integrated purge system removes moisture, maintaining efficiency.

Our Optima XL Series Testing Process

1. Centrifuge technician pre-tests the unit’s (1) speed sometimes to maximum speed for a few minutes, (2) refrigeration (if equipped), (3) spinning if they spin up and spin down properly, (4) checks the buttons, switches, timers if they are all working. Necessary parts for repair are ordered.

2. Once any parts come in for the unit, or they’re working, the centrifuge technician performs any necessary repairs.

3. The centrifuge technician runs the unit to maximum RPMs for a minimum of 1 hour while observing the refrigeration performance (if applicable). During this step, loud/unusual noises, smells, and extra heat build up are observed.

4. The centrifuge technician also observes the proper performance of sensors like temperature, vacuum (if equipped), rotor sensors, tach sensors, latch sensors, etc.

5. After a full hour run, the centrifuge technician takes a photo of the centrifuge display to be shown in the listing photos on New Life Scientific’s e-commerce platforms.

6. The centrifuge technician then does a thorough look over throughout the centrifuge to identify anything that is missing, loose, or damaged. The centrifuge technician follows New Life Scientific’s Centrifuge Technician Checklist at this time to make sure everything is checked accordingly.

7. The refrigeration condenser and chassis cleaned are both handled by blowing out the unit with compressed air or dry ice blasting.

8. Sensors are cleaned and/or re-installed with proper gap. Electrical connections are latched and tightened down properly.

9. Drive mounts, drive brushes, gas springs are checked and replaced, if necessary.

10. The centrifuge is then cleaned and if needed, painted as well, to make sure the unit comes out as standard as we can.

Our Centrifuge Technician Checklist

At New Life Scientific, our technicians test each device thoroughly before shipping to verify performance and functionality. After our centrifuge technician finishes the initial testing process, this Centrifuge Technician Checklist is filled out to record the important information gathered throughout the repair process. This checklist will be available publicly after the unit has undergone tech completion.
