Roller Mixer

The Hawach roller mixer is a laboratory benchtop mixing instrument designed for gentle rolling and rocking motion of blood tubes, viscous liquids, and liquid-solid suspensions. It is widely used in clinical laboratories, blood banks, pharmaceutical R&D, and biotechnology workflows for consistent and non-destructive sample mixing.

Direct Replacement for Thermo Scientific, Bio-Rad & Labquake Roller Mixers

Hawach roller mixers deliver equivalent gentle mixing performance for blood samples, viscous liquids, and liquid-solid suspensions at a significantly lower procurement cost. Use the same protocols – no workflow changes required. All Hawach roller mixers are compatible with standard blood collection tubes (Vacutainer®), centrifuge tubes, culture bottles, and various laboratory containers.

Why Laboratories Replace Thermo Scientific Roller Mixers with Hawach

• Equivalent rolling + rocking motion– Same gentle 360° rotation and end-to-end tilt that preserves blood cell integrity and prevents coagulation.
• Same blood tube compatibility– Works with all standard blood collection tubes (Vacutainer®), centrifuge tubes (5-50 mL), and culture bottles.
• Similar digital timer workflow– Digital models (18102007, 18102008) offer programmable timing (10-999 min) for unattended operation, identical to premium brands.
• Lower procurement cost– 30-50% less than Thermo Scientific, Bio-Rad, or Labquake roller mixers without compromising performance.
• Faster OEM delivery– Standard models in stock; custom orders delivered within 4-6 weeks.
• Easier distributor pricing– Volume discounts and long-term supply agreements available for OEM partners and distributors.
• No protocol revalidation required– Use the same tube dimensions, same speed range, same mixing action – validated workflows transfer directly.

Recommended Roller Mixer by Application – Which Model Should You Choose?

What Is a Roller Mixer?

A roller mixer is a laboratory device that uses multiple motor-driven rollers to simultaneously rotate and gently rock tubes, bottles, or flasks. The unique combination of rolling motion and end-to-end tilt creates a gentle yet highly efficient mixing action, ideal for samples that must not be aerated or subjected to shear stress. A laboratory roller mixer is particularly valuable for blood tube mixing (preventing coagulation), viscous liquids, and liquid-solid suspensions.

Unlike rotators (which tumble samples more vigorously) or vortex mixers (high shear), a roller mixer for blood samples preserves sample integrity while ensuring thorough, homogeneous mixing. This makes the tube roller mixer the instrument of choice for clinical laboratories, blood banks, molecular biology, and pharmaceutical QC facilities.

Typical Applications of Roller Mixers

• Blood sample mixing & anticoagulation– A roller mixer for blood samples keeps anticoagulants evenly mixed in blood collection tubes without damaging blood cells, essential for hematology and coagulation studies.
• Preventing blood clotting– Continuous gentle rolling and rocking motion maintains blood samples in a mixed state, preventing fibrin formation.
• Viscous liquid & liquid-solid suspension mixing– Ideal for samples that are difficult to mix by manual inversion or vortexing (e.g., glycerol solutions, bacterial suspensions).
• Cell culture & reagent preparation– Gently mixing cell suspensions, culture media, and biochemical reagents without introducing air bubbles.
• Immunoprecipitation & protein workflows– End-over-end mixing of antibody-bead suspensions for protein pull-down assays.
• Clinical diagnostics– Homogenizing urine, serum, or plasma samples before analysis.
• Defrosting samples– Gentle rolling action aids uniform thawing of frozen samples without local overheating.

Why Laboratories Choose Hawach Roller Mixers Instead of Generic Brands

• Genuine 360° rolling + rocking motion– Simultaneous rotation and end-to-end tilt ensures thorough mixing of blood collection tubes, viscous liquids, and liquid-solid suspensions without aeration.
• Adjustable speed (20-110 rpm)– Fine-tune mixing intensity for different sample types; slower speeds for delicate blood cells, higher speeds for viscous solutions.
• Digital timer models (10-999 min)– Programmable timing allows unattended operation and consistent, repeatable mixing protocols – ideal for standardized clinical workflows.
• Quiet, low-vibration DC motor– Maintenance-free operation with minimal noise, comfortable for open-bench laboratories.
• Energy-efficient 12 W power consumption– Low operating cost, suitable for continuous use in blood banks and QC labs.
• 5 or 7 rollers– Choose roller count based on throughput; 5-roller models for smaller labs, 7-roller models for higher sample volume.
• Compact footprint– Saves valuable bench space while accommodating multiple tubes or bottles simultaneously.
• Cold room & incubator compatible– Stable operation in temperature-controlled environments (4°C to 60°C).
• Full OEM support– Custom branding, packaging, and private label services for distributors and volume buyers.
