CZGY KS-08 Horizontal Reciprocating Constant-Speed Shaker

Overview

The CZGY KS-08 Horizontal Reciprocating Constant-Speed Shaker is an entry-level, microprocessor-controlled laboratory shaker engineered for reproducible horizontal linear motion in non-temperature-regulated environments. It operates on the principle of reciprocating oscillation—generating consistent back-and-forth displacement along a single axis—making it particularly suitable for applications requiring gentle yet uniform mixing, suspension re-suspension, or aerobic culture agitation where thermal control is not required. Unlike orbital or rotary shakers, its 20 mm stroke amplitude delivers high inertial force at lower rotational equivalents, enhancing particle dispersion efficiency in viscous or particulate-laden samples. Designed for continuous-duty operation (up to 8 hours), the unit integrates real-time speed compensation circuitry to maintain setpoint accuracy across load variations—a critical feature for long-duration assays such as microbial growth monitoring or immunoassay plate washing pre-incubation.

Key Features

• Microprocessor-based speed regulation with dynamic power compensation ensures stable 80–300 rpm output regardless of payload distribution or line voltage fluctuation (220 V ±10%, 50 Hz).
• Extended digital timer (0–9999 minutes) supports both discrete timed runs and indefinite continuous operation (0 h 0 min setting).
• Single-platform design with reinforced aluminum alloy deck (300 × 250 mm usable area) accommodates up to eight 2 L wide-mouth bottles or standard multi-well plates using optional clamps.
• Low-noise DC motor coupled with precision linear guide rails minimizes mechanical drift and bearing wear—optimized for extended service life under routine lab use.
• Dual-color LED status indicators (green = running, red = standby/stop) provide immediate operational feedback without reliance on display interpretation.
• Front-panel intuitive control interface: dedicated ▲/▼ keys for rpm adjustment; H/M buttons for independent hour/minute timer programming.

Sample Compatibility & Compliance

The KS-08 is compatible with standard glass and polypropylene containers including Erlenmeyer flasks (up to 2 L), serum bottles, Petri dish stacks, and 96-well microplates when secured with universal platform clamps (sold separately). Its ambient-only operation classifies it as a Class I, non-thermostatic device per IEC 61010-1:2010 safety standards. While not certified for GMP or GLP environments out-of-the-box, its deterministic timing logic and non-volatile speed memory support audit-ready documentation when integrated into SOP-driven workflows. The absence of heating/cooling elements eliminates condensation risks and simplifies cleaning validation—advantageous for clinical chemistry labs adhering to CLIA or ISO 15189 requirements for ancillary equipment qualification.

Software & Data Management

This shaker operates as a standalone hardware device with no embedded software stack or connectivity interfaces (USB/Ethernet/Bluetooth). All operational parameters—including last-used rpm and timer settings—are retained in non-volatile memory following power cycling. For laboratories requiring electronic record retention, integration with external data loggers or LIMS platforms is achieved via analog voltage output (0–5 V DC proportional to actual rpm) available at the rear terminal block—an optional accessory configurable at time of order. No firmware updates are required; calibration verification is performed manually using a handheld tachometer against the displayed value, satisfying basic metrological traceability per ISO/IEC 17025 Clause 6.5.

Applications

• Microbial culture agitation for aerobic bacteria (e.g., Escherichia coli, Bacillus subtilis) in shake flasks during logarithmic growth phase studies.
• Homogenization of sediment suspensions in environmental water testing (e.g., EPA Method 160.1 for total suspended solids).
• Reagent mixing prior to ELISA, Western blot transfer, or PCR setup—particularly where vortexing may induce foaming or shear-sensitive protein denaturation.
• Extraction protocol support for solid-phase matrixes (e.g., soil, tissue homogenates) using solvent-based leaching systems.
• Pre-analytical sample preparation in clinical labs: blood smear dilution, urine sediment resuspension, and antigen-antibody complex equilibration.

FAQ

Is the KS-08 suitable for sterile cell culture work?
No. It lacks HEPA filtration, UV sterilization, or enclosed chamber design—use only in non-aseptic or secondary containment environments.
Can I mount microplate carriers directly onto the platform?
Yes, provided third-party universal microplate clamps rated for 20 mm stroke amplitude are used; verify mechanical resonance compatibility before deployment.
Does the unit include overload protection?
Yes—integrated thermal cutoff interrupts power if motor winding temperature exceeds 90 °C, resetting automatically upon cooldown.
What maintenance schedule is recommended?
Lubricate linear rail guides every 6 months with silicone-based grease; inspect belt tension quarterly if equipped with timing belt drive (standard configuration uses direct-coupled motor).
Is regulatory documentation (CE, RoHS) available?
CE marking is not applied; however, RoHS-compliant material declarations and factory test reports are supplied with bulk orders upon request.
