Pre-Filter Who??
This filter TYPE is used to protect a finer separations technology: Example This TYPE of filter generally is placed before a 0.2-micron Sterilizing Grades or finer and/or Resin, Hollow Fiber or even a TFF cassette.
What is a Pre-Filter?
I am comprised of resin-bonded Glass Fiber filament on a polypropylene substrate.
What is PreFlow UB/UUA?
We at mAby-mAb-Tech refuse to use any filter that is NOT comprised of PES Pre-Filters or similar! What do you have to guard our columns and TFF systems Cytiva?
What is Supor EAV, SuporLife or Supor we can accept some SG like UECV, or even Supor EKV?
My designation is J100 it should be easy to know what filter I am and do the math to find my micron rating.
HDC II 10 Micron
HDC II
What is polypropylene?
I am a class of Pre-Filter with a claim beyond just a micron rating.
What is a bioburden reducing filter? Or we will accept endotoxin reducing Pre-filter.
I am high area high efficiency Glass Fiber filter, I carry a Charge and I come in a range from 1 to 40 micron! I can be used as both a liquid filter and gas filter!
What is Ultipor GF+?
Here at Hydra Bioinformatics Limited we simply love filtration, but we really do not like PES filters! We only like PVDF or perhaps we would entertain Other MOC! AGAIN NO PES!!!
What is Fluorodyne II DBL, Ultipor NL, Profile II, Profile Star, PreFlow, Starclear, HDC II, Ultipor GF+, BioInert, Posidyne?
My designation is Y050 and I have an absolute micron rating that is so easy to figure out it naught be a problem.
What is Profile 5 Micron?
PreFlow
What is Glass Fiber?
I am a Cytiva filter that can be absolute rated if comprised of polypropylene or nominally rated if comprised of natural materials like Cellulose, Diatomaceous Earth and Perlite. A user relies on the thickness portion of my construction to get tough upstream filtration jobs done.
What is a Depth filter. Seitz Depth/Profile?
As a pre-filter I come in at least six different micron ratings from 0.2 to 1.2 micron but wait there is more! Nylon is my membrane construction, and I also come in an inert variety and even a version that remains at a positive zeta potential across pH!
What is Ultipor, Posidyne, BioInert?
Here at Sports Medicine Incorporated we add DMSO to everything and anything that is a liquid we produce on site. Hey, would you like some Coffee before we start our meeting?
What is Special Purpose Nylon (Y Grade) Ultipor NL (or other Ultipor Nylon grades like NB) also we will accept DMSO Safe Acrodisc from Cytiva Lab?
My "U" gives my pleating arrangement, my "Y" helps to indicate my name. My designation is UY100. Do I look good on this side?
What is Ultipleat Profile 10 Micron?
Profile II, Profile Star
What is depth style polyproplyene?
I am a hydrophobic all polypropylene construction pre-filter with micron ratings between 0.6 and 70 micron! I am a gamma stable membrane filter that can be used for both air filtration or liquid filtration.
What is HDC II?
I am comprised of Nylon and Protect a Cytiva filter named after a mythical horse! Hey wait I am named after the same mythical horse too!
What is Pegasus Protect?
We at Industrial Biotech Incorporated process aggressive chemistries! Why last week we melted PES, Nylon and some PVDF filters just for fun. Cytiva doesn't have anything for us, right? Oh Dr. Pall can you check your garage? Maybe you have something?
What is Rigimesh, PMM or PSS metal media
I am a real performer and have a higher effective filtration area due to my pleating arrangement than my related filter with a II in the title. My designation is A050.
What is Profile Star, 5 Micron?
Ultipor GF+
What is Glass Fiber with a positive charge?
Customers love my polyethersulfone single layer construction and bioburden claim. Once a customer tries me as a Pre-Filter I often spread to other filter guard applications: i.e. Column Guard, TFF Guard or filter used between processing steps.
What is Supor UEAV or EAV?
PVDF with a 0.45 micron rating, am I. Hey Wait I'm special! I am a Pre-Filter with a built in Pre-filtration layer rated at 0.65 micron!
What is Fluorodyne II DBL?
We at Gooey Biotech process fluids with lots of Tween and we hate it when we have to perform post use integrity testing with our glitchy competitor integrity tester. Our slimy competitor PES pre-filters just can't seem to past post-use IT! we hate it so very much as we have been having so many icky issues! What can we do Cytiva?
What is stop using PES filters with Tween and get a Flowstar V?
This "UU_" or "U_" designated Glass Fiber filter can be employed at low flux with liposome, emulsion and difficult feed streams. I would not dare to come in Kleenpak format (I am already in DFA) but I proudly come in Gamma Irradiatable Kleenpak Nova format!
What is Preflow 0.45 micron and 0.2 micron Glass Fiber?
Pegasus Protect
What is Nylon?
