ZiQi ZQTP-S200C & ZQTP-Q200C Rechargeable Rocking and Orbital Shakers

Overview

The ZiQi ZQTP-S200C and ZQTP-Q200C are dual-mode, rechargeable laboratory shakers engineered for precision and operational flexibility in molecular biology, immunology, and histology workflows. Unlike conventional AC-powered shakers, these instruments integrate a high-capacity internal lithium-ion battery—enabling uninterrupted operation in environments where power outlets are inaccessible or undesirable, such as cold rooms, biosafety cabinets, transportable field labs, or multi-location core facilities. The ZQTP-S200C operates in orbital motion (circular rotation), optimized for uniform suspension of gels, microplates, and tube racks during staining, destaining, and hybridization steps. The ZQTP-Q200C employs controlled rocking motion (±45° oscillation around a central axis), delivering gentle yet effective agitation ideal for antibody incubation, membrane washing in Western blotting (WB), and slide processing in immunohistochemistry (IHC) and immunofluorescence (IF). Both models comply with IEC 61010-1 safety standards for laboratory electrical equipment and are constructed with corrosion-resistant ABS housing and stainless-steel tray surfaces to withstand repeated exposure to ethanol, methanol, SDS, and other common lab reagents.

Key Features

• Rechargeable DC power system with intelligent battery management—supports up to 12 hours of continuous operation per full charge; LED display indicates real-time voltage and remaining battery capacity.
• Digital speed control with precise rpm adjustment (40–210 rpm range); resolution of ±1 rpm ensures reproducible agitation across experiments.
• Dual-platform compatibility: ZQTP-S200C features a flat, non-slip orbital platform (265 × 245 mm) rated for 7 kg static load; ZQTP-Q200C incorporates an adjustable-angle rocking cradle with calibrated tilt mechanism (0–90° total swing arc).
• Wide-input universal AC adapter (110–220 V, 50/60 Hz) enables global deployment without voltage converters; auto-sensing circuitry prevents overvoltage damage.
• Brushless DC gearmotor delivers low-noise (<45 dB(A)), low-vibration performance with extended service life and minimal maintenance requirements.
• Robust mechanical architecture—including reinforced support frame, silicone-damped feet, and IP20-rated enclosure—ensures stability during prolonged use and resistance to accidental spills or condensation ingress.

Sample Compatibility & Compliance

These shakers accommodate standard electrophoresis trays (up to 20 × 20 cm), mini-gel cassettes, 6-/12-/24-/96-well plates, glass slides (up to 30 slides per rack), and custom antibody incubation chambers. The non-heated design limits operational temperature to ambient conditions (10–30 °C), making them suitable for placement inside refrigerated cabinets (4 °C), environmental chambers, or laminar flow hoods. Units meet CE marking requirements under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU. While not thermostatically regulated, their passive thermal profile aligns with ASTM E2918-13 guidelines for ambient-conditioned sample agitation in qualitative immunoassays and nucleic acid processing.

Software & Data Management

As standalone benchtop instruments, the ZQTP-S200C and ZQTP-Q200C operate without embedded firmware or network connectivity—eliminating validation overhead associated with computer-controlled systems. All parameter settings (speed, runtime) are retained via non-volatile memory after power cycling. For GLP/GMP-compliant laboratories, manual logbook entries—including date, operator ID, model used, speed setting, duration, and sample type—are recommended per SOP-027 (Shaker Usage Documentation). No electronic audit trail or 21 CFR Part 11 compliance is provided, consistent with Class I non-data-logging laboratory equipment per FDA guidance.

Applications

• Coomassie Blue and silver nitrate gel staining/destaining with improved reagent penetration and reduced background.
• Antibody incubation in WB, ELISA, and IHC protocols—rocking mode reduces primary antibody consumption by up to 40% versus static incubation while enhancing epitope accessibility.
• Post-transfer membrane equilibration and blocking in semi-dry and wet transfer systems.
• Cell monolayer dissociation support (e.g., gentle detachment of adherent lines prior to passaging) when paired with enzymatic buffers.
• Slide washing in automated IHC/IF staining workflows—compatible with standard slide racks and staining jars (e.g., Thermo Shandon™ format).
• Low-shear mixing of viscous samples such as agarose gels, tissue homogenates, or polymer solutions prior to casting or centrifugation.

FAQ

Can these shakers be used inside a 4 °C cold room?
Yes—the absence of heating elements and sealed electronics allow safe operation at temperatures as low as 4 °C. Ensure battery is preconditioned at room temperature before cold-room deployment to maintain discharge efficiency.
What is the expected battery cycle life?
The integrated lithium-ion battery supports ≥500 full charge/discharge cycles while retaining ≥80% of original capacity, assuming storage at 25 °C and periodic calibration.
Is the tray interchangeable between S200C and Q200C models?
No—each model uses a purpose-engineered platform: the S200C has a rigid flat tray with rubberized surface; the Q200C uses a pivoting cradle with adjustable stop pins. Interchangeability would compromise mechanical integrity and motion accuracy.
Does the unit include a power adapter?
Yes—a CE-certified universal AC/DC adapter (input: 100–240 V AC; output: 12 V DC/2 A) is supplied with each unit for charging and direct AC operation.
Are replacement parts available internationally?
ZiQi provides OEM spare parts—including motor assemblies, battery packs, and control PCBs—via authorized regional distributors. Lead time averages 4–6 weeks for air freight delivery outside mainland China.
