Couplers

Here you can find couplers for HPLC & GC, such as connectors, pressure rings, HPLC nuts and union nuts. For example the VICI Jour PEEK coupling parts can be applied for the most commonly used (inorganic and organic) HPLC solvents without the risk of corrosion, contamination with metal or protein degradation, which may occur when stainless steel is used.

If you are looking for a particular coupling part, e.g. in order to pair HPLC cartridges, use our advanced search function. In addition, we carry around 4,000 capillaries and tubes in our laboratory equipment.

GC Press-Fit Connectors (Y-splitter, Presstight Connector)

In various situations, it may be necessary to connect two GC columns with as little leakage and as little dead volume as possible. The use of press-fit connectors (or Y-splitters as well as press-tight connectors) is a economical, effective and fast solution then -  whether it is the repair of a defective column, the addition of a GC retention gap or the division of the column outlet into 2 or 3 directions. Press-Fit connectors are usually made of small capillary glass and are available in different versions depending on use: linear press-fit connectors, Y-Press-Fit connectors and multi-way (4-5)-Press-Fit connectors. At Analytics-Shop.com you will find a variety of different, easy-to-use press fit connectors, including our own brand Altmann Analytik. Do you need help selecting the right connectors? Do not hesitate to contact our customer service.
