PRSC-22 Platform Shaker

Overview

The PRSC-22 Platform Shaker is a precision-engineered orbital shaker designed for consistent, low-shear mixing of biological, microbiological, and biochemical samples in laboratories requiring reproducible agitation under controlled thermal conditions. Utilizing a brushless DC motor and microprocessor-based speed regulation, the instrument delivers stable rotational motion across its full frequency range (20–200 rpm), with minimal vibration transmission to adjacent equipment. Its orbital motion—characterized by a circular path rather than linear reciprocation—ensures uniform suspension of cells, enzymes, or reagents without excessive foaming or shear-induced denaturation. The integrated Peltier-based temperature control system enables precise thermal management from 0 °C to 99 °C, making it suitable for applications ranging from cold-sensitive protein expression studies to high-temperature microbial incubation protocols.

Key Features

• Triple-orbit selection: Switchable orbit diameters (18 mm, 28 mm, and 36 mm) allow optimization of mixing intensity for diverse vessel types—from microcentrifuge tubes and deep-well plates to Erlenmeyer flasks up to 2 L capacity.
• Programmable digital timer: Adjustable timing range from 1 minute to 999 minutes (16 h 39 min), with auto-stop functionality and audible end-of-cycle alert.
• Temperature-controlled platform: Peltier thermoelectric module provides rapid, bidirectional thermal response (< ±0.3 °C stability at setpoint) without external coolant or refrigerant gases.
• Robust mechanical architecture: Stainless steel platform with non-slip silicone mat and reinforced aluminum housing ensure long-term durability and resistance to chemical exposure common in life science labs.
• Intuitive interface: Dual-line LCD display with dedicated keys for rpm, temperature, time, and orbit selection; real-time parameter monitoring during operation.
• Safety compliance: Equipped with over-temperature cutoff, motor stall detection, and lid-open interlock (when used with optional transparent safety cover).

Sample Compatibility & Compliance

The PRSC-22 accommodates standard laboratory vessels—including culture flasks (50 mL to 2 L), multi-well plates (6–96-well), Petri dishes, and tube racks—via customizable clamping accessories (sold separately). Its design conforms to IEC 61010-1:2010 for electrical safety in laboratory equipment and meets ISO 13485 requirements for devices used in regulated biomedical research environments. When operated within validated protocols, the shaker supports GLP-compliant workflows and can be integrated into FDA 21 CFR Part 11–enabled systems through optional RS-232/USB data logging modules (firmware v2.3+).

Software & Data Management

Optional PC connectivity via USB or RS-232 enables remote configuration, real-time parameter logging (rpm, temperature, elapsed time), and export of CSV-formatted datasets for traceability and audit readiness. The companion software suite includes calibration verification tools, user-access-level controls (admin/operator), and electronic signature support aligned with ALCOA+ data integrity principles. All logged events—including parameter changes, start/stop commands, and fault codes—are timestamped and stored locally on device memory (10,000-event buffer) for post-run forensic analysis.

Applications

• Microbial growth kinetics in aerobic liquid cultures (e.g., E. coli, S. cerevisiae)
• Cell suspension maintenance in mammalian bioreactor seed trains
• Enzyme assay preparation requiring homogeneous substrate dispersion
• Antibiotic susceptibility testing using broth microdilution formats
• Protein solubilization and buffer exchange in affinity chromatography workflows
• Environmental sample homogenization prior to nucleic acid extraction
• Quality control of diagnostic reagent batches under temperature-stressed conditions

FAQ

Is the PRSC-22 compatible with CO₂ incubators?
No—the unit is not rated for humidified CO₂ atmospheres; it is intended for ambient-air or dry-heat environments only.
Can multiple orbit settings be programmed in sequence?
No—single-step operation only; sequential ramping requires external programmable logic controller integration.
What is the maximum load capacity per orbit setting?
At 18 mm orbit: 5 kg; at 28 mm orbit: 3.5 kg; at 36 mm orbit: 2.5 kg (uniformly distributed mass).
Does the shaker include validation documentation?
Yes—factory-issued IQ/OQ documentation is provided; PQ protocols must be developed in-house per site-specific SOPs.
Is firmware upgrade supported in the field?
Yes—via USB flash drive using signed firmware binaries issued by the UK technical support team.
