The Easy-to-use Improved Filter Degasser Assembly (IFDA) simultaneously degasses solvents and buffers and removes particles. It is a convenient method for eliminating spurious peaks caused by gas bubbles in your detector, and preventing particle damage to check valves and other system components. A clean mobile phase also prolongs column life.
Each unit includes a PTFE filtering/degassing assembly, ten 1.5 μm PTFE filter membranes, 40 in./1 m × 1/4 in. O.D. PTFE tubing and a heavy wall, graduated, borosilicate glass solvent reservoir. Choose either a 1-liter or a 2-liter reservoir. The 29/32 standard taper PTFE joint on the filtering assembly fits into Ehrlenmeyer flasks and other containers. The filtering assembly accepts any standard 47 mm filter membrane and is compatible with all solvents used in HPLC.
The IFDA fits any appropriate glassware and conveniently works with any vacuum source: oil pumps, water aspirators, house vacuums and diaphragm vacuum pumps.
Teflon Filter Membranes are made of pure of PTFE and therefore have no extractables. The substantial thickness of the membranes (250 micron) allows the fabrication of the membranes without requiring backing material, make them easy to handle and allow them to be reused numerous times. They are chemically inert and can be used interchangeably for organic and aqueous solvents.
Due to the membrane strength, if necessary, liquids can be filtered using pressures exceeding the membranes water initiation pressure or with the aid of wetting agents such as methanol. The functional pore size is 1.5 +/- 0.5 microns.
Improved filter degasser assembly (IFDA) without and with screw caps.
Advantages of using IFDA
SAVES TIME and MONEY - Eliminates spurious peaks caused by outgassing in detectors; eliminates pump down time caused by air locks and particulates in check valves; decreases piston wear and increases column life; eliminates baseline drift due to oxygen concentration changes.
DEGASSES ELUENTS - As particulates are removed.
STURDY CONSTRUCTION - Low center of Gravity.
SAFE - Filters directly into a variety of reservoirs available in 1, 2, 5, or 10 liter sizes.
CONVENIENT - Patented design eliminates the necessity of rotating solvent bottles to attach Filter Degasser; adapters available for a variety of screw cap bottles.
