HengAo HVS-10M/4M Vertical Orbital Shaker for Centrifuge Tubes

Overview

The HengAo HVS-10M/4M Vertical Orbital Shaker is an engineered solution for consistent, low-shear mixing of liquid-phase samples in centrifuge tubes and standard laboratory vessels. Designed around a precision-balanced vertical orbital motion—distinct from reciprocating or rotary shakers—the instrument delivers uniform agitation through controlled circular displacement at adjustable frequencies. This kinematic profile ensures efficient mass transfer during liquid–liquid extraction, reagent homogenization, and suspension stabilization without inducing excessive foaming or sample denaturation. Its dual-platform configuration supports parallel processing across two independently accessible shaking surfaces, enhancing throughput in routine QC labs, food safety testing facilities, and academic biochemistry workflows. The unit operates exclusively at ambient temperature, making it suitable for applications where thermal stability is either unnecessary or actively undesirable—such as volatile solvent extractions or temperature-sensitive enzyme assays.

Key Features

• Vertical orbital drive mechanism with dynamically balanced motor assembly, minimizing mechanical resonance and ensuring long-term operational stability.
• Dual independent shaking platforms (2 × 320 mm × 320 mm), each accommodating standardized tube racks or universal clamping fixtures.
• Digitally controlled timer (0–99 minutes) with automatic shutdown and audible end-of-cycle alert.
• Stepless speed regulation (60–500 rpm) via intuitive rotary encoder, enabling fine-tuned optimization for diverse viscosity ranges—from aqueous buffers to organic solvent mixtures.
• Gentle ramp-up acceleration algorithm prevents sudden torque application, reducing risk of glassware fracture and improving reproducibility in fragile vessel handling.
• Low-noise brushless DC motor (<55 dB(A) at 1 m distance) and vibration-damped chassis construction ensure compatibility with shared lab environments and adjacent sensitive instrumentation.
• Compact footprint (320 × 320 × 340 mm) and modular design facilitate integration into biosafety cabinets, cold rooms, or benchtop workflows with space constraints.

Sample Compatibility & Compliance

The HVS-10M/4M accommodates common cylindrical labware including 10–100 mL conical centrifuge tubes (e.g., Falcon-style), screw-cap volumetric flasks (up to 250 mL), graduated cylinders (50–100 mL), and standard Erlenmeyer flasks (up to 125 mL). Optional universal tube holders and custom rack inserts are available for non-standard geometries. While the device itself does not incorporate active temperature control, its ambient-only operation aligns with ASTM D3924–22 (Standard Practice for Laboratory Environmental Conditions) and ISO/IEC 17025:2017 clause 6.3.2 regarding equipment suitability for intended use. No internal certification for explosion-proof or intrinsically safe operation; users must verify local electrical compliance (e.g., CE marking not included; CE-equivalent conformity assessment required per IEC 61010-1:2010 for laboratory equipment safety).

Software & Data Management

This model operates via embedded microcontroller-based hardware interface only—no PC connectivity, USB port, or proprietary software suite is provided. All parameters (speed, time, start/stop) are set directly on the front-panel digital display with tactile push-button controls. Audit trail functionality is not implemented; however, manual logbook entries or external LIMS-integrated timers may be employed to satisfy GLP/GMP documentation requirements. For regulated environments requiring electronic records, integration with third-party data acquisition systems (e.g., LabVIEW-compatible DAQ modules or RS-232-enabled relay controllers) is feasible via optional analog voltage output (0–5 V) signal mapping to RPM and status indicators.

Applications

• Routine liquid–liquid extraction in food contaminant analysis (e.g., pesticide residue recovery per AOAC 2007.01 QuEChERS method).
• Homogenization of immunoassay reagents prior to ELISA plate loading.
• Suspension of particulate standards for turbidity calibration (ISO 7027-1:2016).
• Pre-analytical mixing of clinical specimens (urine, serum) prior to centrifugation or automated analyzer input.
• Extraction efficiency validation studies under controlled agitation conditions (USP Dissolution Apparatus Performance Verification).
• Cell culture media component blending where shear-sensitive components (e.g., growth factors, lipids) require gentle dispersion.

FAQ

Is the HVS-10M/4M compatible with 50-mL polypropylene centrifuge tubes?

Yes—standard tube racks supporting 50-mL conical tubes are included; maximum load per platform is 16 tubes when using full-height racks.
Does the shaker support continuous operation beyond 99 minutes?

No—the built-in timer caps at 99 minutes; for extended protocols, manual restart or external programmable timer relays are recommended.
Can this unit be placed inside a refrigerated chamber?

Yes, provided ambient chamber temperature remains within 5–40 °C and relative humidity stays below 80% RH non-condensing; verify condensation resistance of electrical connections before installation.
What maintenance intervals are recommended for the motor and drive system?

No scheduled lubrication is required; annual visual inspection of belt tension (if applicable), platform mounting bolts, and power cord integrity is advised per manufacturer’s preventive maintenance checklist.
Is there a version with integrated temperature control?

No—HengAo currently offers temperature-regulated models under separate product lines (e.g., HVS-T series); the HVS-10M/4M is strictly ambient-operation designated.
