The Simplest And Easiest-To-Use Changer
Change of concentration of ion, neurotransmitters or of all possible sort of ligands to be tested is an important issue in modern patch-clamp recordings. The Bio-Logic Rapid Solution Changer is the simplest and easiest-to-use systems to achieve this goal.
The study of neurotransmitters,
ligands, and changes of
concentration of ions are important
issue in modern patch-clamp
experiments. Bio-Logic’s Rapid
Solution Changer, the RSC-200 is
a simple and easy-to-use system
that allows scientist to address
these issues.
The RSC-200 uses a principle known as “sewer
pipes” in which the cell or the tip of the electrode
(in excised-patch mode) is positioned close to the
output of a capillary. The solution to be assayed
flows out of the capillary at a moderate flow rate
gravimetrically. The cell, exposed to this stream,
rapidly
equilibrates in the perfusion solution.
The fact that all the solutions flow in individual
tubes
right to their end eliminates any problems
of dead volumes, washing and cross-contamination
between the solutions to be assayed. This perfusion
principle has been used in many laboratories where
it has been proven that it was a excellent system
for solution assays.
Fast And Automated S
olution Change
The solutions to be assayed are driven to the rotating
head of the RSC-200. The solution exchange is
performed by a very precise rotation of the RSC-200
head which exposes the patch pipette or the cell to
the flow of one of the tubes.
The time of rotation from one tube to the adjacent
one can be programmed from 5 to 800 ms.
The motor is light and vibration free thanks to
the disk rotor technology and to the micro step
command delivered by the controller.
Due to the high number of tubes it is possible
to have one tube for every solution to be assayed.
Compared to fixed tube devices, the rotating head
permits fast changing of the perfusion solution
around the patch pipette without any contamination
from the previous solution.
The Straight Head
One of the important features of RSC head is the easy
changing of solution delivering tubing which eliminates
the necessity of washing and the risk of residual
contaminations. Every RSC-200 system is delivered
with one head. The straight head was designed to
carry standard capillary glass, OD 1.00 mm.
This head gives the following advantages:
capillaries protrude, giving better approach to a cell,
the number of capillaries installed is up to the user,
capillaries take minimum space in the cuvette.
easy changing of capillaries,
easy attachment to the flexible tubing.
9-Electrovalves EVH-9
EVH-9 is a set of 9 valves and is included with
RSC-200. The RSC-200 is capable of driving up to
36 valves (4 sets of valves). The EVH-9 can also be
an optional device which opens the flow only on the
selected tubes. If valves are not used, all solutions
would flow simultaneously. The set of 9 valves are
mounted into their housing. The valves used for RSC-
200 are normally-closed pinch valves. The valves can
be controlled from front panel of the controller or
by software. All valves can be programmed to open
or close synchronously with a tube position change.
