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: 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: 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: 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: 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.
