功能

• Concentration, desalination, and deproteinization of small amounts of valuable samples can be done simply by injecting air with a syringe.
• Since the main body is made of highly transparent resin, the filtration state can be constantly monitored.
• Three types of molecular weight fractions are available: 10,000, 50,000, and 200,000.
• Filtration can be stopped at any concentration factor by stopping the pressurization at any time after pressurization with the syringe.
• High molecular weight is collected in the filter cell and low molecular weight is collected in the filtrate cup, preventing sample loss due to sample transfer.
