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.
