CZGY GY-SGYC-48 Tube Inversion Shaker

Overview

The CZGY GY-SGYC-48 Tube Inversion Shaker is an engineered solution for precise, gentle, and programmable mixing of cylindrical laboratory vessels—primarily test tubes and centrifuge tubes—within life science, clinical diagnostics, and bioprocessing workflows. Unlike orbital or vortex shakers, this instrument operates on the principle of controlled rotational inversion: each of its four independently driven platforms rotates 180° about a horizontal axis, enabling complete liquid re-suspension without excessive shear stress. This motion profile minimizes cellular damage, preserves fragile biomolecular structures (e.g., protein complexes, exosomes, or primary cell suspensions), and ensures high reproducibility in sample homogenization—critical for downstream assays such as ELISA, nucleic acid extraction, immunoassay preparation, and cell culture passaging.

Key Features

• Four independent inversion platforms, each accommodating up to 12 standard 50 mL conical tubes (total capacity: 48 tubes), with customizable clamping fixtures supporting tube volumes from 20 mL to 100 mL
• Stepper motor-driven motion system delivering accurate speed control across a wide range of 1–300 rpm, with real-time digital rpm display on a full-color capacitive touchscreen interface
• Programmable bidirectional operation: users define forward rotation time, reverse rotation time, and inter-phase pause duration—enabling optimization for sensitive samples requiring alternating agitation and settling phases
• Flexible timing resolution: timer supports both minute- and hour-based input (0–9999 units), with automatic shutdown and memory retention of the last used protocol
• Robust aluminum alloy chassis with vibration-dampening feet; designed for stable operation inside refrigerated cabinets, cold rooms, or environmental chambers (operating ambient temperature range: 4–40 °C)
• No integrated heating or cooling elements—intentionally designed as a non-thermal platform to avoid thermal interference during temperature-sensitive protocols

Sample Compatibility & Compliance

The GY-SGYC-48 is validated for use with polypropylene (PP) and polycarbonate (PC) test tubes and centrifuge tubes conforming to ISO 7218 and ASTM D4169 standards for dimensional consistency and mechanical integrity. Its low-shear inversion mechanism meets GLP-aligned requirements for sample integrity preservation in pre-analytical processing. While not certified to IEC 61000-4 electromagnetic compatibility standards out-of-box, the device complies with basic CE marking directives for laboratory electrical equipment (2014/30/EU EMC Directive and 2014/35/EU LVD Directive) when operated within specified voltage (220 V ±10%) and frequency (50 Hz ±1%) tolerances. No regulatory claims are made regarding FDA 21 CFR Part 11 compliance; however, the touchscreen interface supports user-defined password protection and protocol logging—facilitating audit-ready documentation under internal QA/QC frameworks.

Software & Data Management

The embedded firmware provides local protocol storage for up to 20 user-defined methods, each comprising speed setpoint, forward/reverse/pause durations, total run time, and motion direction sequence. All parameters are editable via intuitive icon-based navigation on the 4.3-inch TFT touchscreen. No external PC connectivity (USB, Ethernet, or Bluetooth) is included; data export is limited to manual recording of runtime logs displayed on-screen. For laboratories requiring electronic record integration, third-party serial-to-USB adapters may be used to capture real-time status outputs (e.g., current rpm, elapsed time, active phase) via RS-232 TTL-level signals—subject to custom script development and validation per institutional IT policies.

Applications

• Resuspension of pelleted cells, bacteria, or yeast prior to lysis or viability assessment
• Homogenization of viscous biological matrices (e.g., serum, whole blood, tissue homogenates) without foaming or denaturation
• Equilibration of immunoassay reagents in multi-well plate pre-loading workflows
• Pre-incubation mixing of PCR master mixes containing heat-labile enzymes or modified nucleotides
• Controlled agitation of antibody-conjugated magnetic beads during immunoprecipitation or pull-down assays
• Low-shear blending of hydrogels, liposomal suspensions, or nanoparticle dispersions where shear-induced aggregation must be avoided

FAQ

Can the GY-SGYC-48 be operated inside a −20 °C freezer?
Yes—the unit is rated for ambient operation between 4 °C and 40 °C; however, extended use below 10 °C requires verification of stepper motor torque retention and touchscreen responsiveness under cold conditions. Condensation management is the user’s responsibility.
Is tube clamping hardware interchangeable between different tube sizes?
Yes—CZGY offers optional accessory kits with machined aluminum clamps for 15 mL, 20 mL, 50 mL, and 100 mL tube diameters; all fixtures mount directly onto the standard platform without tools.
Does the shaker support continuous operation beyond 9999 minutes?
No—the timer resets after reaching 9999 units (minutes or hours); for extended runs, users must implement external relay control or segment protocols manually.
What maintenance is required for long-term reliability?
Annual inspection of belt tension (if applicable), cleaning of dust from ventilation grilles, and verification of platform alignment using a spirit level are recommended. Lubrication is not required—the stepper motor and bearing assembly are sealed for lifetime operation.
Can multiple GY-SGYC-48 units be synchronized for parallel processing?
No native synchronization capability exists; each unit operates autonomously. Synchronized start/stop requires external PLC or timer relay coordination at the power supply level.
