HUXI HT-R330 Tilt-Action Orbital Shaker

Overview

The HUXI HT-R330 Tilt-Action Orbital Shaker is an engineered benchtop platform designed for precise, low-shear mixing in life science laboratories. Unlike conventional horizontal orbital shakers, the HT-R330 employs a patented tilt-axis rotational mechanism—where the platform oscillates along a fixed 10° angular plane—generating gentle yet effective three-dimensional motion ideal for delicate biological samples. This kinematic configuration enhances solution homogeneity during electrophoretic gel staining and destaining, membrane hybridization (e.g., Southern/Northern blotting), immunoblot washing, antigen-antibody incubation, and suspension cell culture maintenance. Its compact footprint (330 × 370 × 140 mm) and IP21-rated enclosure allow safe operation inside refrigerated or climate-controlled environments—including standard laboratory cold rooms and incubators—without compromising mechanical stability or thermal integrity.

Key Features

• Integrated tilt-axis drive system with precision-machined curved-arm bearing architecture—ensures zero gear wear, minimal vibration transmission, and long-term operational reproducibility over continuous duty cycles.
• Robust molded polypropylene housing resistant to common laboratory solvents, acids, and alkalis; smooth, non-porous surface facilitates decontamination and complies with ISO 13485 cleanability requirements for biosafety workspaces.
• Dual-line LCD display showing real-time speed (rpm) and remaining timer duration; intuitive rotary encoder interface enables fine-grained speed adjustment (1 rpm increments) and programmable timing up to 99 hours 59 minutes.
• Wide-input universal power supply (100–240 VAC, 50/60 Hz) with internal voltage regulation—certified to IEC 61000-4-5 surge immunity standards for global deployment across diverse electrical infrastructures.
• Front-mounted skirted power switch and control panel with recessed connectors—designed to prevent electrolyte ingress and accidental short-circuiting during liquid handling workflows.
• Maximum load capacity of 5 kg (including clamps and trays); compatible with optional universal clamps, microplate holders (96-/384-well), tube racks (15/50 mL), and custom silicone-coated platforms for high-friction retention.

Sample Compatibility & Compliance

The HT-R330 supports a broad range of sample containers—from Eppendorf tubes and conical centrifuge vessels to glass hybridization bottles and semi-rigid blotting cassettes—without requiring vacuum sealing or external anchoring. Its low-acceleration motion profile (≤0.3 g at 80 rpm, 10° tilt) avoids cell lysis in suspension cultures and preserves epitope integrity during antibody incubations. The device meets CE marking requirements under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD). While not intrinsically rated for Class II biosafety cabinets, its IP21 enclosure and absence of exposed moving parts permit validated integration into GLP-compliant workflows when used with appropriate containment accessories. Environmental operating limits are specified per IEC 60068-2-1 (cold) and IEC 60068-2-2 (dry heat), supporting stable performance between 5 °C and 40 °C ambient temperature at ≤80% RH.

Software & Data Management

The HT-R330 operates as a standalone analog-digital hybrid instrument with no embedded firmware or network interface. All operational parameters are set locally via front-panel controls and retained in non-volatile memory across power cycles. For audit-trail compliance in regulated environments (e.g., FDA 21 CFR Part 11 or ISO/IEC 17025), users may document run conditions manually or integrate the shaker into LIMS via external time-stamped logging devices. Optional RS-232 output modules (sold separately) enable basic serial command triggering (start/stop/pause) and status polling—compatible with LabVIEW™, Python-based automation frameworks, and legacy SCADA systems.

Applications

• Electrophoresis workflow support: uniform dye penetration and background reduction in Coomassie/silver-stained gels; efficient destaining without agitation-induced band diffusion.
• Nucleic acid and protein blotting: consistent buffer exchange during pre-hybridization, probe hybridization, and stringent wash steps—critical for signal-to-noise optimization in chemiluminescent detection.
• Cell-based assays: maintenance of adherent and suspension cultures during antibody labeling, cytokine stimulation, or metabolic labeling protocols where shear stress must remain below 0.5 Pa.
• Clinical microbiology: gentle resuspension of bacterial pellets prior to MALDI-TOF MS target spotting or antibiotic susceptibility testing preparations.
• Diagnostic reagent development: controlled mixing of immunoassay conjugates and capture surfaces to minimize aggregation and maximize binding site accessibility.

FAQ

Can the HT-R330 be operated inside a CO₂ incubator?
Yes—the unit’s thermal design and sealed electronics permit safe use within standard humidified CO₂ incubators operating between 5 °C and 40 °C, provided internal airflow does not directly impinge on the motor housing.
Is speed calibration traceable to NIST standards?
Factory calibration is performed using a dual-channel optical tachometer referenced to an internal quartz oscillator (±0.5% accuracy at 25 °C); full calibration certificates with uncertainty budgets are available upon request for ISO/IEC 17025-accredited labs.
What safety certifications does the HT-R330 hold?
It carries CE marking per EN 61010-1:2010 for electrical safety and EN 61326-1:2013 for electromagnetic compatibility; no UL or CSA listing is included in base configuration.
Does the shaker support multi-step timed programs?
No—the timer is single-stage only; sequential protocols require manual intervention or external programmable logic controllers (PLCs).
Are replacement platforms and clamps available as spare parts?
Yes—HUXI supplies OEM-compatible accessories including aluminum alloy platforms (PN: HT-PLT-AL), silicone-grip microplate holders (PN: HT-MPH-96), and universal tube clamps (PN: HT-CLAMP-UNI), all documented in the official spare parts catalog v2.1.
