Fisher Scientific FB120 Sonic Dismembrator

The Fisher Scientific FB120 Sonic Dismembrator is a compact, high-performance ultrasonic processor engineered for precise cell disruption, homogenization, and molecular sample preparation. Designed for research labs requiring reliable small-volume processing, this system delivers consistent, reproducible sonication for applications ranging from protein extraction to DNA shearing.

Fisher Scientific FB120 features

120W ultrasonic output (20 kHz) for efficient cell disruption
Wide volume range: 0.2–50 mL for versatile applications
Programmable operation (1 sec to 10 hours) for repeatable protocols
Pulse mode (1–59 seconds) to reduce heat buildup and sample degradation
Energy display (Watts & Joules) for process monitoring and validation
Overload protection for safe operation and instrument longevity
Compact footprint (13.5" x 8" x 6") for easy benchtop integration
Handheld converter for flexible use and ergonomic operation
Compatible with multiple probes, cup horns, and multi-sample accessories
Refurbished with 90-day warranty

With 120 watts of ultrasonic power at 20 kHz, the Model 120 efficiently processes volumes from 0.2 mL to 50 mL, making it ideal for genomics, proteomics, and general life science workflows. Its programmable operation, pulse mode, and energy monitoring ensure precise control over sample treatment and minimize variability between runs.

The included lightweight handheld converter and microtip probe allow flexible operation, whether mounted or handheld, while the intuitive interface supports both manual and automated workflows. Built-in overload protection and energy tracking (watts/joules) enhance both safety and reproducibility.

Professionally refurbished by American Instrument Exchange, we fully test each unit and validate to meet original performance standards—providing exceptional value compared to the cost of new equipment while maintaining the reliability your lab demands.

Applications for the Fisherbrand FB120 Sonic Dismembrator include cell lysis and disruption, protein extraction and enzyme release, DNA/RNA shearing (e.g., ChIP assays), emulsification and nanoparticle dispersion, aid microbial and tissue homogenization, among others.

Fisher Scientific FB120 Sonic Dis membratorFrequently Asked Questions (FAQs)

What is a sonic dismembrator used for?

A sonic dismembrator uses ultrasonic energy to break apart cells and particles in liquid samples. The Model 120 is commonly used for cell lysis, protein extraction, and DNA shearing, especially in molecular biology workflows.

What sample volumes can the Model 120 process?

The system supports 0.2 mL to 50 mL, depending on the probe size used. Smaller microtips are ideal for microcentrifuge tubes, while larger probes support higher volumes.

How does programmable operation improve reproducibility?

The built-in timer and pulse settings allow you to standardize sonication cycles, ensuring consistent energy delivery across experiments—critical for reproducible results in assays like ChIP or protein extraction.

What is pulse mode and why is it important?

Pulse mode alternates between on/off cycles, which helps reduce heat buildup and protects temperature-sensitive samples from degradation during sonication.

Does the system require special installation?

No special installation is required. The unit operates on standard 110/117V power and is designed for benchtop use. However, a stand is recommended for hands-free operation.

How loud is the instrument during operation?

Like most ultrasonic processors, it produces audible high-frequency noise. Use of the sound enclosure (included with purchase from American Instrument Exchange) or operating within a lab hood is recommended for user comfort.

FAQ

Does the equipment come with a warranty?

Yes, all equipment from American Instrument Exchange comes with a warranty.
Used/reconditioned/refurbished equipment is tested to make sure it operates to the manufacturer's specifications and comes with a 90-day warranty (unless otherwise noted). New equipment comes with a warranty from the manufacturer.

How do you test and recondition the equipment?

Testing requirements vary across all the equipment categories we sell. Temperature controlled units are tested with NIST traceable probes and data loggers. Gaskets, external housing, glass, handles, controls and control screens are all thoroughly inspected for integrity and functionality.
We test all equipment using the manufacturer's parameters and specifications to confirm that the unit operates properly.

How do products ship from American Instrument Exchange?

We can ship products both nationally and internationally using a well-established network of transporters. Smaller items will ship via UPS. Larger equipment will be palletized and shipped either LTL or air-ride, depending on the specific equipment and/or delivery requirements.

Return and order cancellation policy

American Instrument Exchange will accept the return of any product that is not working as represented and could not be replaced or repaired to the customer's satisfaction during the warranty period. Customers who cancel orders after refurbishing has begun will be subject to a cancellation and restocking fee of between 20% and 40%.

Are discounts available for educational or non-profit institutions, or for bulk purchases?

Yes – call or email us today with a list of equipment you're looking for and we can potentially put together a quote that includes a discount.

How does your price matching policy work?

We strive to keep our pricing competitive and reasonable. If you find comparable items for sale at a lower price from other vendors please send us a link and or quote for the item and we'll do our best to match or beat the price.

Can I see the equipment in person before committing to a purchase?

Customers are welcome to make an appointment to view equipment in our warehouse. Given our workload we may not be able to test or clean the equipment prior to your arrival if you have not committed to an order.

1023 Western Avenue is a working warehouse, not a showroom, and customers should dress appropriately and wear closed toe shoes.

Can I ship products that I purchased elsewhere to American Instrument for repair?

Yes – please see our repair services page for more information.
