Sealed with PTFE Endcaps

Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards

Often used in GC inlet liners to improve sample vaporization, and/or to keep non-volatile material from entering the column

Eliminates need for dangerous and expensive hydrogen gas cylinders

Solid phase extraction (SPE) is a technique commonly used in laboratories to isolate analytes of interest from complex matrices.

Offer both high deactivation and unique selectivity.

Disposal valve liners eliminate contamination from one sample to the next.

Available in High and Low Pressure options

Unlike other vacuum manifolds, the Visiprep system contains a patented valve system that allows for precise flow control through each SPE tube via rotating, independent, screw-type valves situated in each port within the manifold cover.

Solid phase microextraction technique can be used for GC/MS analysis. It helps in simplifying and speeds up the sample preparation. It also reduces solvent requirement for the extraction.

Tedlar™ is recommended in several US EPA methods for sampling VOCs and sulfur compounds.

For ion-selective electrodes

The best trap available for removing hydrocarbons and other organics from carrier, fuel, air, and other gas streams

Has the ability to operate in either a volumetric or a mass mode

This product is a certified reference material (CRM) certified to International Standards BS EN ISO / IEC 17025 and ISO 17034 under UKAS accreditation.

Use for very accurate flow regulation. Install a flow measuring device downstream. Nuts and ferrules included. An optional vernier handle (Cat. No. 22122, order separately) is available for added convenience.

Shipped in 0.05% NaN₃ and 0.1 M Na₂SO₄ in 0.1 M Phosphate Buffer, pH 6.7.

SPME fiber assembly Divinylbenzene/Carboxen/Polydimethylsiloxane (DVB/CAR/PDMS) is manufactured with a flexible metal alloy used in the needle, plunger, and fiber core.

For Rapid Removal of Adsorbent from TLC Plates

Unlike other vacuum manifolds, the Visiprep system contains a patented valve system that allows for precise flow control through each SPE tube via rotating, independent, screw-type valves situated in each port within the manifold cover.

An economical metal column should be used for less demanding applications where the inertness of glass is not required. This column is of a general configuration, and can be carefully bent to fit most instruments.

Pharmalytes™ are ampholytes which are used to create a pH gradient under application of an electric field.

TLC Developing Tanks come complete with the developing tank and lid.
