HPLC Guard Columns and Cartridges
Waters Corp Porasil Silica Radial-Pak Guard, 125Å, 15 - 20 µm, 40 mm X 10 mm, 2/pk
Waters Porasil 15 - 20µm silica packing material provides long column life and low backpressure. The packing also has a high surface area making it ideal for preparative work.
Waters Corp Nova-Pak C8 Guard-Pak Insert, 60Å, 4 µm, 10/pk
The 4 µm small particle size of Nova-Pak bonded phases offers high resolution, more efficient and faster chromatography by using shorter columns, reducing solvent consumption or by using longer columns to resolve even the most complex mixture. Semi-preparative columns with 6µm particle size packings give you an unparalleled range of separation possibilities. Stringent QC procedures in our cGMP manufacturing facility ensure batch-to-batch reproducibility.
Waters Corp DeltaPak C4 Radial-Pak Column, 100Å, 15 µm, 47 mm X 300 mm, 1/pk
Delta-Pak packings, ideal for the separation of peptides, proteins, and natural products, are based on a highly stable, bonded, endcapped 5µm or 15µm spherical silica. Delta-Pak is available in two different pore sizes (100Å and 300Å) with either C4 or C18 bonded phase. Delta-Pak packings are available in different cartridge and column configurations, providing consistent and predictable scale-up capabilities for milligram-to-gram scale purification. Also, by having the same chemistry available on a high-efficiency 5µm particle, you can easily check the purity of your fractions.
Waters Corp Bondapak C18 Radial-Pak Guard, 125Å, 15 - 20 µm, 25 mm X 10 mm, 2/pk
Bondapak C18 is available in two different particle sizes, 15-20µm and 37-55µm, providing easy method transfer from µBondapak through preparative scale up. If you are developing a new purification protocol, Bondapak provides the best balance between resolution, throughput and cost.
Waters Corp µBondapak C18 Radial-Pak Guard, 125Å, 10 µm, 40 mm X 10 mm, 2/pk
µBondapak C18 columns are general purpose, silica-based, reversed-phase C18 columns that are based on 10 µm particle technology. As a starting point for preparative chromatography, no other column can provide the balance between resolution, throughput and cost.
Waters Corp Bondapak C18 Radial-Pak Guard, 125Å, 15 - 20 µm, 40 mm X 10 mm, 2/pk
Bondapak C18 is available in two different particle sizes, 15-20µm and 37-55µm, providing easy method transfer from µBondapak through preparative scale up. If you are developing a new purification protocol, Bondapak provides the best balance between resolution, throughput and cost.
Waters Corp DeltaPak C18 Guard Column, 300Å, 5 µm, 10/pk
Delta-Pak packings, ideal for the separation of peptides, proteins, and natural products, are based on a highly stable, bonded, endcapped 5µm or 15µm spherical silica. Delta-Pak is available in two different pore sizes (100Å and 300Å) with either C4 or C18 bonded phase. Delta-Pak packings are available in different cartridge and column configurations, providing consistent and predictable scale-up capabilities for milligram-to-gram scale purification. Also, by having the same chemistry available on a high-efficiency 5µm particle, you can easily check the purity of your fractions.
