概述
- Accommodates a wide range of pilot/process hollow fiber cartridges (size 35, 45, 55, 65, 75, 85) and Kvick Flow cassettes with optional accessory kit
- Quick, simple changeover of pore sizes—extremely useful in sequential MF/UF applications (i.e., cell harvest/protein concentration)
- Flexibility in valving permits interchange between remote process tank and CIP tank
- Reversible pump for maximum product recovery
- UF pore sizes from 3,000 to 750,000 NMWC and MF pore sizes from 0.1 to 0.65 micron
- Membrane areas from 9.9 to 560 ft² (0.9 to 52 m²) with optional four-cartridge configuration and Membrane areas from 10 to 150 ft² (0.9 to 27.9 m²) using Kvick Flow cassettes
Modular kits enhance the flexibility of the GrandStand systems to meet the needs of process development and process manufacturing groups without the delivery issues associated with custom systems. Simply purchase the base system and the modules needed for your specific application. The system and selected modules ship together with easy instructions to assemble them on site. A service option is available for onsite assembly combined with IQ/OQ. For those with changing requirements, simply select the modules that provide the necessary system upgrade thereby eliminating the need to purchase a completely new system.
Available modules facilitate customization for:
- Varying process volumes
- Data acquisition
- Flow rate
- Pressure
- Temperature
- Conductivity
- UV
- Permeate flow control
- Filter type flexibility: hollow fiber or cassette
- Steam-in-place (SIP)
Feature rich basic system
The basic GrandStand system consists of a heavy-duty stainless steel frame, positive displacement rotary lobe pump for gentle recirculation of biological solutions, diaphragm type backpressure valve, sanitary inlet and outlet pressure gauges, and a cone bottom clean-inplace (CIP) tank. A programmable AC inverter features a multitude of functions including the ability to set the pump acceleration time as well as to monitor pump speed. A high-pressure switch is incorporated for equipment and operator safety.
Robust streamlined design
The GrandStand system's narrow profile allows it to fit through standard door openings for easy transport from the lab to the cold room to the manufacturing area. Heavy-duty swivel casters with a total locking feature provide mobility and stability. The system is designed to interchange easily between process and cleaning cycles. The modular design enhances the versatility of the GrandStand system to address changing needs associated with scale up and sophistication from pilot to process scale.
