Syringeless Filter Devices
Introduction
Syringeless filters are preassembled filtration devices specially used in HPLC for the purification and analysis
of samples. It is a single disposable unit contains the function of common samples bottles (including the lid and
cushions), disposable needles and syringe filters.MS ®syringeless filter adopt standard size, can cooperate
with HPLC instrument perfectly. Two membrane aperture are available to meet all of your filtration needs, :0.22um
and 0.45um, all materials such as PVDF, Nylon, PTFE, PES, PP are available. Syringeless filters are specially
designed for the filtration of small doses of sample, especially suitable for the light sensitive and air sensitive
compounds analysis.
How it works
Each unit includes two parts:a chamber and plunger.
A filtration membrane on the end of the plunger and on the other. When using, sample is injected into below
chamber, then press the plunger manual, positive pressure forces the filtrate up into the reservoir of the plunger
Application
