SISCO's laboratory roller mixer features premium silicone rollers to ensure gentle, consistent contact with sample containers, accommodating centrifuge tubes from φ6 to 34 mm and 1 L reagent bottles from φ45 to 100 mm. The brushless motor delivers stable, precise speed with minimal deviation, while the intuitive LCD digital display makes parameter monitoring and adjustment fast and effortless. Whether you're running routine blood sample mixing or processing large-volume reagent bottles, this roller mixer offers the reliability, versatility, and ease of use your lab demands.
Silicone Rollers with Dual Roller Spacing and Anti-Jam Design
- The high-quality silicone rollers of the mixer — 280 mm in length — provide smooth, continuous horizontal rolling motion that keeps samples in steady circulation within the tube, ensuring thorough and uniform mixing without interruption.
- The dual roller center spacing of 34/68 mm enables seamless compatibility with both centrifuge tubes (φ6~34 mm) and 1 L reagent bottles (φ45~100 mm), covering everything from fine-diameter blood collection tubes to large-volume laboratory containers.
- Internally, the roller mixer features a purpose-engineered anti-jam drive structure that significantly reduces operational friction, delivering stable, low-failure-rate performance well-suited to extended continuous use in demanding laboratory environments.
LCD Digital Display and Brushless Motor
- The roller mixer's LCD digital display provides real-time visibility of operating parameters, giving lab personnel an at-a-glance overview of current speed and timer settings at all times.
- The touch-sensitive interface, combined with electronic digital button controls, enables precise, repeatable adjustment of speed and timing — minimizing input errors and supporting consistent experimental reproducibility across runs.
- Powered by a brushless motor, the roller mixer operates with minimal noise, low speed deviation, and reduced mechanical wear — making it a long-service-life solution for laboratories that prioritize operational stability and low total cost of ownership.
Applications
Lab mixers are widely used in biomedical research for cell culture, PCR, and immunoassays, ensuring uniform and reliable mixing of samples. In the chemical industry and scientific laboratories, lab mixing equipment supports catalytic reactions, solution preparation, protein crystallization, and nucleic acid hybridization, improving experimental stability and repeatability. In clinical testing and diagnostics, laboratory vortex mixers are commonly used for preparing blood and urine samples and for antimicrobial susceptibility testing, ensuring accurate and dependable results.

Q1: What is the difference between a horizontal-axis and a high-low-axis roller mixer, and how do I choose?
A1: In a high-low-axis roller mixer, the rollers are arranged in an alternating high-low pattern, generating a compound rocking-and-rolling motion that is particularly effective for highly viscous samples or applications requiring three-dimensional tumbling. The horizontal-axis design, by contrast, uses parallel rollers at equal height to produce smooth, steady horizontal rolling — better suited to vibration-sensitive samples or experiments that require prolonged, low-disturbance mixing. If your lab routinely handles both standard centrifuge tubes and large-volume reagent bottles, the horizontal-axis model's 34/68 mm dual-spacing design offers broader container compatibility, making it the more versatile choice for mixed-format workflows.
Q2: Can this lab roller mixer handle different tube sizes at the same time?
A2: Yes. The 34/68 mm dual roller center spacing allows the mixer to simultaneously accommodate centrifuge tubes (φ6~34 mm) and 1 L reagent bottles (φ45~100 mm), covering a wide range of container formats in a single run. For the most consistent mixing results, we recommend grouping tubes of similar diameter within the same batch where possible, ensuring even rolling contact pressure across all samples.
Q3: What are the practical advantages of a brushless motor over a brushed motor?
A3: Brushless motors eliminate the carbon brush assembly found in conventional brushed motors, fundamentally reducing mechanical friction and wear. The result is quieter operation, more stable and precise speed control with lower deviation, and a significantly longer service life, with no brush replacements needed over time. For laboratories running extended continuous mixing sessions or operating in noise-sensitive environments, a brushless motor is the more dependable and cost-efficient choice in the long run.
Tips: How do you make the most of this mixer's wide container compatibility?
One of the standout features of this horizontal-axis roller mixer is its 34/68 mm dual roller spacing, which unlocks broad container compatibility in a single instrument — handling everything from fine-diameter blood collection tubes to 1 L reagent bottles without the need for accessory swaps. In practice, plan your sample loading based on tube diameter: arrange smaller-diameter tubes side by side across the rollers to maximize throughput per run, while larger reagent bottles benefit from the wider 68 mm spacing for stable, drift-free rolling. For viscous liquids or solid-liquid suspensions, dialing down the speed and extending the mixing duration tends to produce more uniform dispersion than running at maximum rpm for a short period. With thoughtful pairing of speed and timer settings, this mixer can seamlessly transition between sample types and container formats — helping your lab get the most out of every run.
