Sorvall X4 Pro-MD Specs and Features

The X4 Pro-MD's durable construction can withstand the demands of daily use, while the easy-to-use controls make it accessible to technicians without extensive training. Primary features include:

• High-capacity processing: Handles up to four 1,000-milliliter samples in a single run, reducing the processing times for large batches.

• Powerful centrifugal force: Generates forces over 25,000 times gravity, providing excellent separation efficiency for various sample types.

• Compact size: Measures 27.2 by 22.3 by 14.2 inches, fitting easily on standard laboratory benches.

• Standard electrical requirements: Operates on 120 volts of power, eliminating the need for special outlets or adaptors.

• Rotor flexibility: Compatible with multiple rotor types to match specific applications and materials.

Our 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. 

Thermo Scientific Sorvall X4-Pro MD Benchtop Centrifuge Applications

The X4 Pro-MD works well for various applications where sample separation and processing efficiency are critical. Examples include:

• Cell Biology and Biochemistry - The centrifuge is commonly used for harvesting cells from cultures in bioprocessing, cell culture studies, and in research applications. It aids in separating proteins from other cellular components in studies related to biochemistry. It also helps isolate and concentrate RNA or DNA from biological samples.

• Blood Separation - Centrifuges are used to separate blood components like plasma, serum and cells for diagnostic tests, blood banking, or plasma collection for medical treatments.

• Urine and Stool Sample Analysis - For isolating cells, bacteria, or other particles for microbiological analysis or diagnostics.

• Microbiological Testing - Separation of microorganisms from biological samples for culture or identification.

• Water Quality Testing - Used to separate particulates, microorganisms, or contaminants from water samples for analysis in environmental monitoring.

• Viral Particle Isolation - In research on viruses, benchtop centrifuges help isolate viral particles from cell cultures or biological samples.

• Gene Therapy Applications - In genetic research, centrifuges assist in separating viral vectors, plasmids, or other genetic materials from cultures.

• Nanoparticle Synthesis - Used for separating nanoparticles or other fine materials form solution after synthesis.

• Food and Beverage Industry - Used to separate fats from milk or cream during processing in the dairy industry. Used to remove pulp and other solid particles from fruit juice. In the fermentation process for beer and wine production, centrifuges help separate yeast from liquids.

• Forensic Science - In forensic investigations, benchtop centrifuges help isolate blood components or bodily fluids for DNA extraction and analysis. It can also help to analyze drugs, poisons, or other toxic compounds.

• Teaching Tool/Educational - In educational settings, benchtop centrifuges are used in laboratory classes for demonstrations on centrifugation principles and sample preparation techniques.
