Standard roller mixer

• Six extended roller design: 280mm long rollers hold multiple blood collection tubes & centrifuge tubes at once for uniform gentle rolling, minimal structural gaps for convenient daily cleaning.
• Stepless adjustable speed range 0–70rpm: Low speed gears for mild anti-coagulation mixing of blood samples, medium-high speed gears for dispersion of viscous reagents and liquid-solid suspensions, covering full gradient mixing demands of clinical and biochemical tests.
• Combined rocking & rolling motion with 24mm amplitude: Simultaneous rolling and slight reciprocating shake effectively prevent sedimentation and stratification of cells & precipitates, without violent impact damaging fragile biological specimens.
• Optional dual motor versions: Cost-effective LRM-R6 brushed model for low-frequency short-term use; low-noise low-vibration LRM-R6-Plus brushless model requires no carbon brush replacement throughout service life, cutting maintenance cost for year-round high-frequency operation.
• 4kg high rated load capacity: Supports batch processing of dozens of blood tubes in a single run, perfect for high-throughput sample pre-processing in hospital clinical labs.
• Continuous operation mode only: No timed auto-stop function, enables 24-hour non-stop long-term rolling for overnight blood balancing and mixing tests.
• Universal 100–240V wide voltage design: Automatically adapts to 50/60Hz power supply standards of global labs, IP21 dust & splash resistance to resist minor liquid spills in routine lab environments.
• Low-profile compact body: Small footprint allows placement on constant-temperature benches and inside biosafety cabinets for synchronous sample mixing.

• Blood tube placement operation: Place blood collection tubes and centrifuge tubes stably between six rollers for firm clamping; tubes will not slide or topple during 24mm rocking & rolling motion.
• Power connection & standby operation: Connect 100–240V AC power cord, the unit completes hardware self-check. Rotate the speed knob to adjust speed from 0–70rpm; speed range is judged via scale marks without digital screen.
• Long-term continuous mixing operation: Start the unit after setting suitable speed for non-stop rocking & rolling, suitable for overnight blood anti-coagulation and low-speed incubation of immune precipitation. The unit has no auto-stop function and requires manual power-off to halt operation.
• Matching operation with constant-temperature benches & biosafety cabinets: Low-profile body can be fully placed inside standard constant-temperature workstations and biosafety cabinets to realize synchronous constant-temperature storage and gentle rolling mixing of samples.
• Shutdown operation after experiment: Manually cut off power upon test completion, take out all test tubes and wipe residual blood and reagent liquid off roller surfaces.
• Daily cleaning maintenance operation: Wipe residual liquid on roller surfaces and body gaps after each use to keep the unit dry and clean and prevent roller corrosion from waste liquid. Regular carbon brush wear inspection is required for brushed model; no daily motor maintenance is needed for brushless model.
• Storage maintenance for long idle periods: Disconnect power during long downtime, clean stains off rollers, store the whole unit under dry low-humidity environment of 5–40℃ to extend motor service life.

1. Choose LRM-R6-Plus brushless model for year-round high-frequency blood sample processing with maintenance-free design; cost-effective LRM-R6 brushed model for short-term low-frequency teaching and temporary testing.
2. This tube roller is designed for anti-coagulation mixing of whole blood and plasma; vortex mixers are recommended for intensive resuspension of heavy precipitates in micro samples.
3. Suitable for batch mixing of multiple blood tubes in one run, not recommended for single micro EP tube mixing.
4. Compact body fits constant-temperature benches and biosafety cabinets; avoid long-term operation in high-humidity condensing environment which damages carbon brushes of brushed motor.

2. Application Scenarios

1. Packaging structure: Standard export hard color carton fully lined with high-density shock-absorbing foam, separate slots for main unit and power cord to prevent collision damage to rollers and speed knob during long sea and land transit.
2. Bulk order protection: Reinforced thickened buffer layer is applied by default for large-volume foreign trade orders to reduce risk of equipment failure caused by extrusion and impact of medium-size body during transit.
3. Standard package accessories: LRM-R6 / LRM-R6-Plus tube roller main unit, matching wide-voltage power cord, full printed operation manual; no optional customized fixtures or trays are available for this model.
4. Package size note: Outer carton dimension and full-set gross weight are estimated reference values only, final data subject to actual factory outgoing packaging.
5. In-stock lead time: Standard in-stock models without custom accessories ship within 3–10 working days.
6. Optional logistics channels: Sea freight, air freight and full-truck land transport available, dedicated export logistics line for bulk overseas export of medium-size lab mixing instruments.

• Complete technical datasheet of LRM-R6 / LRM-R6-Plus: The original specification sheet contains all hardware values including amplitude, load capacity, motor and unit dimension, fully supported by official data.
• Standard operation SOP for blood sample mixing on tube roller: The original brochure marks compatibility with blood anti-coagulation mixing, supported by native product function.
• Overall dimension engineering drawing of the unit: Original official parameters provide W×D×H size 485×250×100mm for outline drawing reference.
• Factory inspection report for stability test of motor and full 4kg load: The original sheet distinguishes brushed/brushless motor and marks 4kg rated load, the inspection report only corresponds to inherent hardware performance without adding unsubstantiated parameters.

• Can the combined rocking & rolling amplitude of this tube roller be adjusted manually?
  Answer: The amplitude is fixed at 24mm, no amplitude adjustment structure is equipped on the unit.
• What is the maximum allowable total weight of rollers, test tubes and samples?
  Answer: Rated max total load is 4kg, overload operation is forbidden to prevent motor overload and unbalanced body shaking.
• What is the continuously adjustable speed range, and is there a digital display screen?
  Answer: Speed is stepless adjustable from 0–70rpm; only scale marks are equipped without LCD/LED digital screen, speed level is judged via printed scales.
• Does the unit support timed auto-stop function?
  Answer: No timing module or timer screen is equipped, only 24-hour continuous running is supported, manual power-off is required to stop operation.
• What is the core difference between the two versions, and are other parameters identical?
  Answer: The only difference is motor type: LRM-R6 adopts brushed DC motor, LRM-R6-Plus adopts maintenance-free brushless DC motor; all other hardware parameters including amplitude, load, rollers, speed, dimension and power are exactly the same.
• What is the protection class and required temperature & humidity for stable operation?
  Answer: Protection class IP21; operating environment 5–40℃, relative humidity ≤80%RH without condensation.
• What are overall unit dimension, roller specification and net weight of the unit?
