Simple, ergonomic aspiration device for cell culture
Mettler Toledo QuickFlow Aspirator
The Rainin QuickFlow from Mettler Toledo is a high-performance vacuum aspiration system technically engineered for the safe and efficient removal of liquid biological waste. The system features a self-contained design that integrates a precision vacuum pump with a robust collection bottle, managed through an ergonomic handle that provides continuous or pressure-sensitive flow control.
This technical solution is specifically designed for cell culture applications, proteomics, and genomics workflows where the removal of media or buffers from flasks, dishes, and multi-well plates must be performed without disturbing delicate cell layers or risking aerosol contamination.
Ergonomic Handle with Dual Mode Control
The technical centerpiece of the QuickFlow is its ergonomic handle, designed to minimize hand fatigue during repetitive aspiration tasks. The handle features a dual-mode operation: a pressure-sensitive button for precise, manual control of the aspiration rate, and a switch for continuous flow. This flexibility allows researchers to switch between delicate operations, such as removing media from sensitive cell monolayers, and high-volume tasks like emptying large flasks, ensuring optimal efficiency across diverse laboratory protocols.
High-Efficiency Vacuum Pump and Speed Regulation
The QuickFlow system is powered by an internal, maintenance-free vacuum pump capable of generating consistent suction for various liquid types. Technically, the system allows the user to adjust the vacuum strength to suit the specific application, whether it requires a gentle draw for micro-volumes or rapid suction for bulk waste removal. This adjustable speed regulation prevents the accidental aspiration of cell layers and reduces noise levels, contributing to a more controlled and quieter laboratory environment.
Non-Contact Liquid Level Sensor for Overflow Protection
To prevent the accidental overflow of hazardous biological waste, the QuickFlow incorporates an advanced non-contact liquid level sensor. This sensor technically monitors the volume within the collection bottle and automatically shuts down the vacuum pump when the bottle reaches maximum capacity. Because the sensor is non-contact, it remains isolated from the waste stream, reducing maintenance requirements and eliminating the risk of sensor fouling or cross-contamination that occurs with traditional float-based switches.
Versatile Adapter Compatibility for Multi-Format Labware
The QuickFlow is engineered for technical versatility, featuring a quick-connect system for various aspiration adapters. These include single-channel adapters for glass Pasteur pipettes and universal plastic tips, as well as 8-channel adapters for 96-well plate processing. This modular approach allows the system to transition seamlessly between different labware formats, such as Petri dishes, T-flasks, and multi-well plates, ensuring that the aspiration path is always optimized for the vessel being processed.
Robust Collection Bottle Options and Material Integrity
The system offers interchangeable collection bottles available in 2-liter and 4-liter capacities, constructed from high-quality materials like Polypropylene (PP) or glass. These bottles are technically designed to withstand high vacuum pressures without deformation and are fully autoclavable to ensure effective decontamination. The secure screw-cap design with integrated vacuum ports ensures a leak-proof seal, protecting the operator and the environment from exposure to potentially infectious biological agents.
Quick-Connect Couplings for Safe Fluid Path Management
Safety and ease of use are enhanced through the use of self-sealing quick-connect couplings. These technical connectors allow the user to detach the collection bottle from the vacuum base without the risk of drips or leaks. When disconnected, the couplings automatically seal the vacuum lines, maintaining the integrity of the fluid path and preventing the release of aerosols. This feature is critical for the safe transport of waste bottles to the autoclave or disposal area.
Integrated Hydrophobic Filter for Pump Protection
The QuickFlow includes an integrated hydrophobic filter located between the collection bottle and the vacuum pump. This filter acts as a technical barrier, preventing liquids and aerosols from entering the internal pump mechanism. By blocking moisture and biological contaminants, the filter ensures the long-term reliability of the vacuum motor and prevents environmental contamination of the laboratory air. The filter is easily replaceable, facilitating routine maintenance and compliance with safety protocols.
Compact Design and Benchtop Integration
Technically designed with a small footprint, the QuickFlow system integrates easily into crowded laboratory environments, including laminar flow hoods and biosafety cabinets. Its stable base prevents tipping, and the organized cable and tubing management system keeps the workspace clean and safe. The intuitive layout and color-coded components allow for rapid assembly and operation, making it a reliable technical asset for high-throughput laboratories requiring dependable liquid waste management.
