Description<br />
Multiflux-2 Linear Connectors allow multiple tubing lines to be simultaneously connected<br />
in a small space with precise alignment of flow paths. The Linear Connector 7-way is ideal<br />
for microfluidics or general purpose lab-use and provides fast and reliable connection of<br />
0.8 mm O.D. tubing. The in-built tube restraint mechanism holds tubes securely in place<br />
for robust operation. <strong>Dolomite</strong> has a range of compatible Multiflux-2 Interfaces to enable<br />
the connector to be used with microfluidic chips. Alternatively, compatible interfaces (see<br />
design guide) can be designed to allow the connector to be used in any instrument or<br />
system to simplify fluidic routing and reduce assembly time.<br />
Left to Right: Linear Connector 7-way (Part No. 3200148), Linear Connector 7-way female (Part No. 3200291) and<br />
Linear Connector 7-way microchannel (Part No. 3200290)<br />
The Linear Connector 7-way Microchannel is designed for optimum alignment of tubing<br />
bores to microfluidic channels. This high performance connection features micro-scale<br />
pins, which locate directly into the microfluidic chip to provide the alignment.<br />
The Linear Connector 7-way In-line consists of 7 individual tubing to tubing connections<br />
using the Linear Connector 7-way and Linear Connector 7-way Female. This provides a<br />
multi-way continuous flow path which is quick to connect and disconnect.<br />
The Linear Connector Funnel enables a single 1.6mm O.D. tube to be connected to a<br />
series of fluid ports on a microfluidic chip. It is typically used in conjunction with Telos 7-<br />
channel chips where the single tube feeds seven input fluid holes or collects from seven<br />
output channels. The Linear Connector Funnel is compatible with Multiflux-2 interfaces<br />
and can be used in combination with the Linear Connector 7-way female allowing one<br />
1.6mm O.D. tube to be connected directly to seven 0.8mm O.D. output tubes.<br />

Multiflux-2 Interface Design Guide<br />
It is simple to design a Multiflux-2 compatible interface to utilise the benefits of a Multiflux-<br />
2 multi-way connection in any fluidic system. The diagram below shows the required<br />
geometry and position of the M3 threaded holes with counterbore to accept the connector<br />
thumb screws. An optional orientation pin can be added to the right hand hole of the<br />
interface to ensure that the connector cannot be accidentally connected in the reverse<br />
orientation.<br />
