This column-packing technology is based on a combination of vacuum suction with subsequent column bed compression that stabilises the packing. A common water-jet pump is used to generate the vacuum. The sorbent slurry is sucked through a packing reservoir into the column by applying low pressure at the bottom end of the column.

Supplier: Restek

Ultra C8 is a conventional monomeric octylsilane column offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape. It is made of high-purity, type-B silica that minimises activity and creates high-density bonding. These columns are designed for selective and reliable HPLC applications.

Supplier: Restek

These Viva columns are based on a wide pore material designed for optimal large-molecule separations. Base-deactivated spherical silica is useful for normal-phase or HILIC separations. These columns have a narrow distribution around the mean pore size, permitting a larger portion of the silica surface to play a role in the separation.

Supplier: Restek

Viva C8 columns are conventional monomeric octylsilane columns offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape over a traditional C18 phase. These general-purpose C8 columns are suitable for a wide range of compounds from acidic through slightly basic.

Supplier: TEKNOMEK

Supplier: Restek

Ultra amino columns are made of high-purity, spherical shaped type-B silica that minimises activity and creates high-density bonding. These columns are designed for selective and reliable HPLC applications. Aminopropylsilane provides reproducible retention and efficiency for normal-phase or HILIC analysis of simple sugars.

Supplier: Restek

Highly base-deactivated spherical silica manufactured by Restek. Cyano bonding. Suitable for analyses of a wide range of compounds, from acidic through slightly basic. Also useful for confirmation of analyses on a C18 or C8 column. Can be used in normal phase or reversed phase mode of separation.

Supplier: JUSTRITE MANUFACTURING

Self-close corrosive containers with stainless steel hardware are specifically designed to resist acids and caustics. Oval containers make the most of storage capacity and are marked in liters, quarts and gallons to permit accurate filling and dispensing.

Supplier: Thermo Fisher Scientific

These ODS columns are suitable for non-polar and moderately polar analytes including acids, neutrals and lipophilic compounds. All column phases are endcapped.

Supplier: WTW

A wide choice of tests is available, for routine quantitative analysis in different applications, designed for use with WTW spectrophotometers and photometers. The test is automatically recognised by the laboratory instruments (via a barcoding system) and results are displayed in the appropriate units. Due to the different photometer optics, one test may yield different measuring ranges in different instruments; LED photometers may have smaller measuring ranges for the same test.

Supplier: MACHEREY-NAGEL

NUCLEODUR® C18 Pyramid is an octadecyl modified silica phase with polar endcapping, especially designed for use in eluent systems of up to 100% water.

Supplier: HAMILTON BONADUZ

The 1000 series is a mid volume Gastight® syringe. Gastight® syringes are ideal for dispensing both liquids and gases. They have a precision machined PTFE plunger tip which creates a leak-free seal. With the tight fit, the tip essentially wipes the interior of the syringe barrel free of sample. This feature is particularly useful with heterogeneous samples as it reduces the chance that a deposit will occur and cause the plunger to freeze.

Supplier: Restek

Highly base-deactivated spherical silica manufactured by Restek. Monomeric C8 bonding. Similar to Pinnacle® DB C18, but the shorter alkyl chain provides less hydrophobic retention. Less retention can be useful for shortening analysis time, if resolution is adequate. Replaces Hypersil® BDS C8 and Pinnacle® C8 Amine.

Supplier: Avantor
