The columns include an integral fine filter rated at 15–45 microns, suitable for retaining packed resin beds while allowing controlled gravity flow of liquid samples.
Are these sample preparation columns sterile?
No. These columns are supplied non-sterile. If your protocol requires sterility, perform validated autoclaving or use a sterile alternative compatible with your workflow.
What is the column made from?
The column body is molded polypropylene (PP), chosen for low extractables and broad compatibility with common aqueous and organic sample preparation buffers.
How many columns come in each pack?
Each unit of sale is one bag containing 200 columns (200/Bag), priced per pack for bulk laboratory and core-facility use.
