Overview
The PP-4 Orbital Shaking Platform is a precision-engineered laboratory shaker designed for consistent, low-shear orbital motion to support cell culture maintenance, solubility studies, reagent mixing, and general sample agitation. Operating on the principle of circular orbital motion with fixed amplitude (typically 20 mm nominal), the PP-4 delivers uniform kinetic energy transfer across multi-well plates, flasks, and tubes without inducing excessive turbulence or foaming—critical for sensitive biological suspensions and viscous media. Its brushless DC motor ensures silent, maintenance-free operation and long-term speed stability, while the robust aluminum alloy platform provides dimensional integrity under continuous load. The device is engineered for integration into regulated laboratory environments where reproducibility, mechanical reliability, and minimal vibration transmission are essential.
Key Features
- Orbital shaking motion with precisely controlled rotational frequency (range: 30–300 rpm, digitally adjustable in 1-rpm increments)
- Fixed 20 mm orbital diameter optimized for compatibility with standard microplates (96-/384-well), Erlenmeyer flasks (up to 2 L), and tube racks
- Brushless DC motor delivering high torque at low speeds and exceptional thermal stability during extended operation
- Programmable timer (1 min to 99 hr 59 min) with auto-stop and audible alert
- Leveling feet and anti-slip silicone mat included for secure placement on benchtops and compatibility with incubator integration
- CE-marked; compliant with IEC 61010-1:2010 for electrical safety in laboratory equipment
Sample Compatibility & Compliance
The PP-4 supports a broad range of container formats including polystyrene microplates, glass and PET flasks, centrifuge tubes (15–50 mL), and custom jigs via optional clamping accessories. It is validated for use in ambient, refrigerated (4 °C), and CO2 incubator environments (with optional humidity-resistant enclosure). From a regulatory standpoint, the unit meets fundamental requirements for GLP-compliant laboratories: its digital interface logs setpoints (speed, time) and supports manual entry of operator ID and batch identifiers. While not inherently 21 CFR Part 11 compliant, it can be operated within a validated workflow that includes external audit trail documentation per FDA and ISO/IEC 17025 guidelines.
Software & Data Management
The PP-4 operates via an intuitive front-panel interface with LED display and tactile membrane buttons—no proprietary software required for basic operation. For laboratories requiring electronic record retention, optional RS-232 or USB-to-serial adapters enable connection to LIMS or ELN systems. When interfaced, the device transmits real-time operational status (current speed, elapsed time, target duration) and accepts remote start/stop commands. All parameter changes are timestamped locally (non-volatile memory), supporting traceability in quality-controlled workflows aligned with ISO 9001 and ISO/IEC 17025 documentation standards.
Applications
- Maintenance of suspension mammalian and insect cell cultures in shaken bioreactors and flasks
- Homogenization of immunoassay reagents and antibody conjugates prior to plate coating
- Dissolution testing of pharmaceutical formulations under USP agitation conditions
- Extraction efficiency optimization in environmental sample preparation (e.g., soil leaching, water sedimentation)
- Pre-analytical mixing of clinical specimens to prevent phase separation in serum/plasma collection tubes
- Supporting enzymatic reactions requiring gentle agitation without shear-induced denaturation
FAQ
Is the PP-4 suitable for use inside a CO2 incubator?
Yes—when equipped with the optional incubator-rated housing kit (IPK-PP4), the unit is rated for continuous operation at 37 °C and 5% CO2, with condensation-resistant electronics.
Does the PP-4 offer programmable ramp-up or ramp-down profiles?
No—the PP-4 maintains constant speed throughout the run cycle. For applications requiring acceleration/deceleration control, consider the PP-4+ variant with advanced motion profiling firmware.
Can the platform accommodate uneven loads or off-center vessels?
The unit includes dynamic imbalance compensation up to 10% mass asymmetry across the platform surface; however, optimal performance and longevity require balanced loading per manufacturer guidelines.
What calibration documentation is provided?
Each unit ships with a factory-verified speed calibration certificate (traceable to NPL UK standards) and a mechanical leveling verification report.
Is service and technical support available outside the UK?
Yes—authorized service partners operate in over 32 countries, with remote diagnostics support and spare parts logistics coordinated through the global distributor network.
