Double Door Ports & Single Door Hatches

To offer you various options for your application, or budget we have different styles of Double Door Ports & Single Door Hatches available. Double door ports ensure safe import and export procedures. Also known as Quadro-Lock Ports, these are often used in BL3/4 and Germ-Free conditions. This is due to their secure nature and the minimal risk of breaches.

Meanwhile, single door hatches allow larger access for your equipment, prior to sterilisation. Single door hatches are also easier and quicker to use. These are preferable when ease of use and speed are required. Furthermore, we are able to offer a range of PVC port caps; either with bungs or screw tops to aid in sterilisation.

We are also able to install any existing port options you may have or want from different manufacturers. Such as, special hatches or rapid transfer ports. Please contact us to discuss your requirements.

Ports with flexible film caps are a simple and quick way to ensure that you have complete security on your Isolator; while also providing the ability to quickly and easily change the cap should this be necessary.
