Digital bead mill homogenizer for cell lysis and tissue disruption, with 500–4800 SPM speed range and multi-volume tube capacity.
The Ohaus Bead Genie SI-B103 is a precision bead mill homogenizer designed for efficient cell lysis, tissue homogenization, and microbial disruption in molecular biology and biotechnology laboratories. It supports a speed range of 500 to 4800 strokes per minute (SPM) using a reciprocating motion with a 19 mm stroke length, ensuring thorough sample processing across multiple biological applications such as DNA/RNA extraction, protein extraction, yeast cell lysis, and bacterial and fungal cell disruption.
Key features include a digital control system with a countdown timer adjustable from 1 second to 99 minutes, allowing precise protocol customization critical in molecular diagnostics workflows and bioprocessing pipelines. The device accommodates various sample volumes with interchangeable, tool-free tube holders supporting tubes of 1.5/2.0 mL (12 tubes), 15 mL (6 tubes), and 50 mL (3 tubes) volumes, making it versatile for different experimental scales common in synthetic biology and biomanufacturing environments.
The bead mill’s robust coated aluminum housing and solid metal construction (6 kg) minimize vibrations, ensuring stable operation for reproducible results. The unit features five bead size options (0.1 mm to 5 mm), enhancing flexibility for diverse sample types including plant tissues and soil. Suitable for use within 0°C to 38°C and 95% non-condensing humidity, it operates on 100-240 VAC, 50/60Hz, accommodating global lab standards.
This homogenizer’s backlit LCD display facilitates clear operational readouts, optimized for laboratory settings requiring reliable, efficient sample disruption for downstream applications such as live-cell imaging, fluorescence analysis, and biomedical engineering research.
Overall, the Ohaus Bead Genie SI-B103 is widely recognized among scientists for its durability and adaptability in critical gene editing sample preparation, molecular cloning workflows, and other biotechnology research and clinical diagnostics requiring efficient mechanical cell disruption instruments.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
