The majority of available perfusion systems have long lines of tubing, which have to be filled be<strong>for</strong>e con-<br />
ducting experiments. However, sometimes applied substances are available only in limited quantities or are<br />
extremely expensive, prohibiting the usage of conventional perfusion systems. This system utilizes small<br />
plastic tubes with conical bottom and thin Teflon tubing to connect to your system. It can be used with as<br />
little as 00 µl volumes of solution. Tubes with solutions are simply threaded into the holder. Solutions are<br />
easy to refill during the experiment. Can be used with miniature manifolds. Uses pressure source built-inside<br />
the controller to deliver the solutions, unless the solutions are withdrawn by a negative pressure like<br />
in controlled flow system or intracellular perfusion setup. The system comes with all necessary tubing and<br />
fitting to connect to a single pressure source. The small size of 91 x 48 x 17 mm (without tubing attached)<br />
allows to position solutions near your sample. Can be attached to a ft. rod (included). Comes with X-block<br />
to attach onto a standard 0.5 in. stand. The body has 6.5 mm I.D. opening, which allows to mount the system<br />
on a micromanipulator. Includes 6 plastic replaceable tubes (2 and 3.5ml).<br />
Includes Miniature Manifold <strong>for</strong> Single Cell Superfusion<br />
Miniature manifolds are used to achieve fast solution application to small samples (single cells, <strong>for</strong> example).<br />
Due to the small size of the sample, solution exchange around the sample can happen in as fast as<br />
few ms. The miniature manifolds also offer advantage of not contaminating the whole bath chamber, but<br />
applying the substances locally (provided that perfusion chamber is used with frequent wash). Comes with<br />
three replaceable threaded tips of 360, 250 and 100 micron I.D. Incorporates 2 ft. long Teflon tubing <strong>for</strong> direct<br />
connection to perfusion systems. Inside tubing is easy to wash. The threaded replaceable tips are washable<br />
and allow one to use the manifold with solutions under higher pressure. The length of tips is around<br />
in., which can be cut to the required length. Incorporates 10cm long 4mm O.D. rod to mount on miniature<br />
manipulators and 7mm O.D. adapter to mount on regular manipulators. Incorporates eight separate channels.<br />
If used with less number of solutions, multiple channels are filled with the same solution, which accelerates<br />
washout and delivery. Includes two nozzles to use with small volume chambers as a regular manifold (the<br />
rod fits inside magnetic holders MTH).<br />
Includes Flow Control Unit, up to 22 ml/min Suction<br />
Comes with a set of tubing <strong>for</strong> different flow ranges up to 22 ml/min. Includes a DC power supply. This high<br />
flow rate unit can be used <strong>for</strong> solution suction/aspiration from open perfusion chambers. The unit is configured<br />
as an analog option <strong>for</strong> automatic outflow when perfusion is turned ON.<br />
16-channel Valve Controller<br />
The included 6-channel controller can operate in AUTO Memory mode, when a set of chosen valves opens<br />
automatically at the time the other valves close. This is useful <strong>for</strong> automatic switching to preset solutions<br />
after the test solution is OFF, and provides uninterrupted solution flow.<br />
INHIBIT mode with manual and external controls allows you to switch all channels OFF at once, if required.<br />
The controller has an option <strong>for</strong> valves control by Binary Encoding using only 2-4 digital inputs, in case if<br />
a limited number of digital outputs are available in your system. The RS232 port allows automation of solution<br />
switching and integration with imaging systems.<br />
ANALOG output can be configured to monitor channel switching during manual operation. By default,<br />
ANALOG output is used to switch an outflow unit ON automatically every time perfusion is ON.<br />
