Overview
The RH-100 Flip-Over Shaker is a microprocessor-controlled laboratory shaker engineered for gentle yet effective homogenization of low-volume liquid samples in tubes, vials, and microplates. Unlike orbital or reciprocating shakers, the RH-100 employs a precisely synchronized 3D tumble rotation mechanism—combining controlled flip-over (180° inversion), axial roll, and subtle pitch motion—to ensure uniform suspension of particulates, cell aggregates, or immunoassay reagents without shear-induced damage. This motion profile is particularly suited for applications requiring complete re-suspension of settled material while minimizing foam formation or sample splashing. Designed for benchtop use in biosafety cabinets and cleanroom-adjacent environments, the RH-100 operates without thermal regulation, making it ideal for ambient-temperature incubation-compatible protocols such as antibody labeling, ELISA plate washing priming, plasmid miniprep resuspension, and bacterial culture mixing prior to centrifugation.
Key Features
- Microcontroller-based timing system with real-time LCD display showing both elapsed time and instantaneous speed (rpm)
- Intuitive rotary knob interface for rapid parameter adjustment—no menu navigation required
- Programmable multi-phase operation: users may define discrete or interleaved sequences of rotation, flip-over, and pause intervals
- Configurable phase durations: flip/rotate steps adjustable from 1 to 250 seconds; pause intervals from 1 to 5 seconds
- Brushless DC motor drive ensures consistent speed accuracy across the full 10–100 rpm range, zero maintenance, and silent operation (<45 dB(A) at 1 m)
- Modular tray system supports interchangeable platforms—including universal tube racks (12×15 mm, 12×18 mm), PCR strip holders, and 96-well microplate adapters—enabling cross-format compatibility
- Robust aluminum alloy chassis with non-slip silicone feet ensures stability under load (up to 6 kg) and vibration damping during extended runs
Sample Compatibility & Compliance
The RH-100 accommodates standard laboratory consumables including 0.5–50 mL conical tubes, cryovials, glass test tubes, and flat-bottomed microplates. Its 3D motion profile has been validated for reproducible mixing of viscous solutions (up to 10,000 cP), low-density cell suspensions (e.g., PBMCs, yeast), and solid-phase immunoassays. While the instrument itself does not carry CE marking for IVD use or FDA 510(k) clearance, its mechanical design and electrical safety comply with IEC 61010-1:2010 (Edition 3) for laboratory equipment. The absence of heating/cooling elements eliminates thermal drift concerns, supporting GLP-aligned documentation where ambient temperature logging is performed externally per SOP.
Software & Data Management
The RH-100 operates as a standalone instrument with no embedded software stack or network interface. All operational parameters are set locally via hardware controls and retained in non-volatile memory across power cycles. For traceability in regulated environments, users may integrate external time-stamped logging via USB-connected data loggers or facility-wide environmental monitoring systems. Though not natively 21 CFR Part 11 compliant, the device supports audit-ready workflows when paired with electronic lab notebooks (ELNs) that record operator ID, start/stop timestamps, and selected program IDs—consistent with ALCOA+ principles for raw data integrity.
Applications
- Resuspension of lyophilized reagents and pelletized cells prior to downstream analysis
- Uniform coating of magnetic beads in nucleic acid extraction kits
- Pre-incubation mixing for lateral flow assay development and validation
- Homogenization of tissue lysates in low-speed, high-gentleness protocols
- Agitation of agarose gels during staining/destaining steps
- Consistent mixing of calibration standards and QC samples in clinical microbiology labs
FAQ
Is the RH-100 suitable for use inside a CO₂ incubator?
No—the unit lacks IP-rated enclosure and temperature-rated components; it is rated for ambient operation only (10–30°C, <80% RH non-condensing).
Can multiple programs be stored internally?
Yes—up to 5 user-defined protocols (each comprising up to 3 sequential phases) can be saved and recalled via numeric key shortcuts.
What is the maximum tube diameter supported on the standard platform?
The universal rack accommodates tubes up to 30 mm in outer diameter, including 50 mL conical polypropylene tubes.
Does the device include a lid lock or safety interlock?
No—due to its low-energy, non-centrifugal motion profile, the RH-100 does not require mechanical lid locking per IEC 61010-2-020.
Is firmware upgrade capability available?
Firmware updates are not supported; all functionality is implemented in hardened microcode and verified during factory calibration.
