Qiangle SHZ-88A Reciprocating Water Bath Incubator Shaker

Overview

The Qiangle SHZ-88A Reciprocating Water Bath Incubator Shaker is an engineered platform for precise temperature-controlled agitation of liquid samples in life science laboratories. It operates on the principle of reciprocating (linear back-and-forth) motion within a thermostatically regulated water bath environment—distinct from orbital or rotary shakers—enabling uniform heat transfer and gentle yet effective mixing ideal for cell culture suspension, enzyme kinetics assays, solubility studies, and microbial growth applications. The unit integrates a high-capacity water jacket with direct-contact thermal coupling between the bath medium and sample vessels, ensuring rapid equilibration and minimal thermal lag. Its microprocessor-based PID temperature controller delivers stable setpoint maintenance across the full operating range (ambient water temperature up to 98 °C), with adaptive tuning logic that compensates for regional ambient variations—particularly beneficial in laboratories subject to seasonal humidity or ambient temperature fluctuations common in northern and southern climatic zones.

Key Features

• Reciprocating oscillation mechanism with adjustable frequency (40–300 rpm) and fixed 26 mm stroke amplitude, optimized for low-shear mixing of sensitive biological suspensions.
• Intelligent PID temperature control system with ±0.1 °C setpoint accuracy and ±0.5 °C spatial uniformity across the bath volume, validated per ASTM E2251-22 (Standard Practice for Calibration of Laboratory Thermometers).
• Single-tier stainless-steel shaking platform accommodating up to nine 250 mL Erlenmeyer flasks or equivalent vessels; platform surface treated for corrosion resistance and easy decontamination.
• Digital timer with 0–999 minute programmable range, supporting unattended operation and reproducible incubation durations essential for GLP-compliant protocols.
• 1200 W heating element with over-temperature protection and automatic cut-off, compliant with IEC 61010-1 safety standards for laboratory equipment.
• Robust chassis construction (30 kg net weight) minimizes vibration transmission to adjacent instrumentation; non-slip rubber feet ensure stability during extended high-frequency operation.

Sample Compatibility & Compliance

The SHZ-88A supports standard glassware including borosilicate flasks (50–500 mL), test tubes, and multi-well plates when used with compatible adapters. Its water bath design ensures direct thermal coupling—critical for applications requiring tight thermal control, such as thermophilic bacterial cultivation (e.g., Geobacillus stearothermophilus), protein denaturation studies, or dissolution testing per USP <711>. The device meets CE marking requirements under the EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. While not FDA 21 CFR Part 11–certified out-of-the-box, its digital logging interface (via optional RS-232 output) enables integration into validated data acquisition systems supporting audit trails and electronic signature workflows required in GMP environments.

Software & Data Management

The SHZ-88A features a local front-panel interface only—no embedded software or cloud connectivity. All operational parameters (set temperature, oscillation speed, timer value) are displayed on a dual-line LCD and retained in non-volatile memory during power interruption. For traceable recordkeeping, users may connect the optional RS-232 serial port to external data loggers or LIMS-compatible terminals. When integrated with third-party SCADA platforms, the device supports timestamped parameter export at user-defined intervals, facilitating compliance with ISO/IEC 17025 documentation requirements for calibration and usage history.

Applications

• Maintenance of aerobic microbial cultures under controlled thermal and agitation conditions (e.g., E. coli, Bacillus subtilis)
• Enzyme activity assays requiring consistent temperature and homogeneous mixing
• Dissolution testing of pharmaceutical dosage forms in aqueous media
• Extraction protocols for plant metabolites or nucleic acids where thermal stability and shear sensitivity are critical
• Pre-incubation of reagents prior to PCR setup or ELISA plate coating steps
• Quality control of buffer solutions and media preparations in biomanufacturing support labs

FAQ

Is the SHZ-88A suitable for use with volatile organic solvents?
No. The water bath design and open-top configuration are intended exclusively for aqueous or water-miscible solutions. Use of flammable or low-boiling-point solvents poses fire and vapor inhalation hazards and voids warranty coverage.

Can the oscillation amplitude be adjusted?
No. The 26 mm stroke is mechanically fixed to ensure structural integrity and long-term repeatability. Variable amplitude would compromise thermal uniformity and mechanical resonance control.

What is the recommended maintenance interval for the water bath?
Drain, clean, and descale the bath chamber every 3 months using 1% citric acid solution. Replace distilled or deionized water before each new experimental series to prevent mineral deposition and microbial biofilm formation.

Does the unit include a calibration certificate?
Factory calibration is performed against NIST-traceable references; a Certificate of Conformance (CoC) is supplied with each shipment. Optional UKAS-accredited calibration certificates are available upon request at additional cost.
