Description
Multiflux-2 Linear Connectors allow multiple tubing lines to be simultaneously connected
in a small space with precise alignment of flow paths. The Linear Connector 7-way is ideal
for microfluidics or general purpose lab-use and provides fast and reliable connection of
0.8 mm O.D. tubing. The in-built tube restraint mechanism holds tubes securely in place
for robust operation. Dolomite has a range of compatible Multiflux-2 Interfaces to enable
the connector to be used with microfluidic chips. Alternatively, compatible interfaces (see
design guide) can be designed to allow the connector to be used in any instrument or
system to simplify fluidic routing and reduce assembly time.

Linear Connector 7-way microchannel (Part No. 3200290)
The Linear Connector 7-way Microchannel is designed for optimum alignment of tubing
bores to microfluidic channels. This high performance connection features micro-scale
pins, which locate directly into the microfluidic chip to provide the alignment.
The Linear Connector 7-way In-line consists of 7 individual tubing to tubing connections
using the Linear Connector 7-way and Linear Connector 7-way Female. This provides a
multi-way continuous flow path which is quick to connect and disconnect.
The Linear Connector Funnel enables a single 1.6mm O.D. tube to be connected to a
series of fluid ports on a microfluidic chip. It is typically used in conjunction with Telos 7-
channel chips where the single tube feeds seven input fluid holes or collects from seven
output channels. The Linear Connector Funnel is compatible with Multiflux-2 interfaces
and can be used in combination with the Linear Connector 7-way female allowing one
1.6mm O.D. tube to be connected directly to seven 0.8mm O.D. output tubes.

The Linear Connector Seal 7-way (FKM) (Part No. 3200299) is used together with the
Linear Connector 7-way (Part No. 3200148) to provide fast and reliable connection of 0.8
mm O.D. tubing.
The Funnel FFKM Seal (Part No. 3200371) is a spare seal for the Linear Connector
Funnel (Part No. 3200362). Note FFKM is not compatible with Fluorinated oils.

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