Waters Corp Resolve C18 Radial-Pak Column, 90Å, 10 µm, 8 mm X 100 mm, 1/pk
The non-encapped Resolve C18 column offers significantly different selectivity compared to similar HPLC packings like Nova-Pak and µBondapak. The change in chromatographic behavior is most commonly noticed with polar compounds, which are typically more retained.
Sigma Aldrich Fine Chemicals Biosciences Column PD-10 Empty Cytiva
Empty Disposable PD-10 Columns are economical plastic columns for single-use applications using gravity flow. The columns hold up to approx. 13 mL of chromatography media. The frits can be used as an upper bed support that prevents the medium from running dry under gravity flow.Together with LabMate Buffer Reservoir up to 25 mL of buffer and/or sample can be applied which reduces handling time considerably.
