CONTROLLED FLOW PERFUSION SYSTEM
This is a perfusion system for precise linear control of solution flow rate over the range from 0.34 µl/min to 22 ml/min. Precision design and miniature size minimize pulsations to provide smooth perfusion. Designed for stable solution flow or substance application during imaging, calcium and other ions measurement, recording, biochemical assays or small organs and animals perfusion. Used with small chambers in lab-on-chip setups, imaging and recording workstations, and to perfuse small organs and animals in micro-perfusion setups. Ten-turn dials (or analog inputs) allow to calibrate each channel independently and to apply one or multiple substances by switching channels manually or through data acquisition and imaging software. Manual single units can be also used as a source of vacuum to remove solution from your sample chambers during perfusion because the units are so small that they can be mounted next to your samples.. You can accurately mix different solutions or generate dose-response curves using only two solutions: control and concentrated test compound. You can even generate concentration gradients in time to simulate substance distribution in time, and concentration gradients throughout the space of small chambers to assess chemotaxis, for example. Each channel can be controlled manually, by analog signal, TTL or through RS232 connection for fully automated setups controlled through our or third party software packages, imaging for example (optional USB adapters are also available). Multipple units can be attached to each other to form a multi-channel system. The size of the 2-channel unit is 4x2.5x1.85 in (separate from the controller). The controller can read analog signals (temperature, for example) to automate environment control. The controllers can be also used with our optional disposable flow meters and high power switch to setup an automated system to measure and dispense solutions using high flow rate pumps in the range from 70ml/min to 25 l/min, with precision of 200µl.
MICROMANIPULATOR for PATCH/SLICE-CLAMP, no drift manipulator
This is an extremely stable micromanipulator. MLW-3 uses water instead of oil in the hydraulic system.
The expansion coefficient of water is 1/4 that of oil. As a result, the drift is reduced by four times. The size of the drive unit
cartridge is five times greater than the size of operating cartridge. This reduces drift additional five times. The principle of leverage
is adopted in the drive unit, which reduces drift by another five times - total of hundred times reduction in drift. Movement range:
coarse - 30 mm (X, Y, and Z), fine - 400 µm (X, Y, Z). Full rotation of knob (fine) - 10 µm, (coarse) - 4 mm. Minimum
graduation - 40 nm. Dimensions: control unit - W110 x D110 x H132 mm, drive unit - W170 x D175 x H100 mm. Weight: control unit -
1.60 kg, drive unit - 1.15 kg

Stereo microscopes are equipped with five different magnification objectives (switch-able) and come with a set of five eyepieces (8X and 15X).
The magnification ranges from 3.3X to 100.8X for sf-100 models
(working distance - 95 mm, prices start from $660.25), and
from 2.4X to 47.2X for sf-50 models (working distance - 170 mm, prices start from $565.25).
The fully equipped inverted microscope costs
only $3,277.50 and comes with four objectives (working distance from 20 to 3
mm), two attachments for phase contrast and polarization, illuminator, a set of
six filters and an additional eyepiece with two interchangeable measuring
reticles (item# in-iq902).
MICROMANIPULATOR with ANTI-VIBRATION DESIGN
Nmn-25 is a mechanical micromanipulator suitable for both conventional patch
clamping or slice patch. Compact model with the high performance of the NMN-21 manipulator.
Anti-vibration design was used in the body construction. Many manipulators can
be mounted on the microscope stage. The mechanical formula provides stable
performance and does not generate electrical noise. Detachable electrode holder
fixing part could be rotated for easy electrode exchange. Working distance: X/Z axis
(Coarse) 15mm X/Z axis (Fine) 6mm; one rotation of fine control knob - 250µm.
Y-axis (Coarse and Fine) - 10mm; one rotation of fine control knob - 292µm.
PERFUSION CHAMBER-INSERT for PETRI DISH - PCP1
Cells cultured in 35 mm Petri dishes are a popular research tool used in
numerous applications, including patch clamping and intracellular ion probe
imaging. However, true perfusion (continuous inflow and outflow) of solutions
can be difficult to configure. Drug delivery without an outflow requires
a Picospritzer-type microinjector, but ultimately results in contamination
of the entire dish after only a few applications. This forces scientists
to plate cells on coverslips for placement into specially designed
perfusion chambers. However, such transfer is a time consuming process
which introduces the potential for contamination plus additional expense.
The PCP1 chamber was designed by scientists after several years of
patch clamp research combined with external perfusion of single cells
cultured in Petri dishes. The chamber has separate openings for solution
inflow and outflow that dampen the fluctuations of the liquid level in the
working compartment and prevents bubbles from entering the chamber. An
adjustable metal suction tube (included) helps to control the level of liquid in the dish. The chamber was designed for use
with
automated perfusion systems
and can accommodate commercially available Teflon manifolds (optional).
Choose from chambers to fit Corning, Falcon, or Nunc 35 mm dishes. The
chamber also fits to thin coverslip bottom dishes and
could be a perfect companion for those who want to change solutions during fluorescence
experiments.
Bath Chamber with Glass coverslip bottom - PCCS1
The most flexible and easy to use perfusion chamber-assembly for upright and inverted microscopes. To accommodate the wide range
of possible applications, this system consists of three movable and replaceable elements: perfusion chamber, magnetic adjustable
tubing/electrode holders and a stainless microscope stage insert. It could be used with upright or inverted microscopes,
fluorescent or water immersion objectives, tissue slices or single cells, and could be used as stand alone or could be easily
adapted to perfusion systems.
OOCYTE PERFUSION CHAMBER - OPC3
Expression of recombinant receptors in oocytes have
been one of the favorite choices for researchers to assess the pharmacology of recombinant receptors.
Since the oocytes are 1 - 1.5 mm in diameter, however, the fast solution exchange around the oocyte
could be a problem. After several years of electrophysiological research,
we have designed a Xenopus oocyte perfusion chamber for use in
automated and unattended experiments. One of the major characteristic of the
chamber presented is a small working volume (~20 μl), which allows the fast solution exchanges.
Combined with automated perfusion systems, this chamber lets the researcher to obtained dose-response
data fast and easily. It could be also used with Voltage Clamp amplifiers, which
employ two electrodes bath clamp.
PATCH CLAMP AMPLIFIER WPC-100
WPC-100 is an excellent patch clamp amplifier for single channel and whole cell patch clamping
in both voltage clamp and current clamp modes. The amplifier noise in the patch mode is
only 15 fA rms at 1 kHz bandwidth (4-pole Bessel filter, open headstage).
Works with any data acquisition software and hardware.
Small Volume Perfusion System - SVDS1
The majority of available perfusion systems have long lines of tubing, which have to be filled before conducting experiments.
However, sometimes applied substances are available only in limited quantities or are extremely expensive, prohibiting the usage
of conventional perfusion systems. To minimize the waste of applied substances, we have designed the 8-channel small volume
delivery system. The system utilizes small plastic tubes with conical bottom and thin polyimide tubing to connect to a maltibarrel
micropipette or a micromanifold. It could be used with as little as 100
µl volumes of perfusate.
AUTOMATED GEL/BLOT WASHING
ValveLink or
ValveBank perfusion systems can automate
washing of electrophoresis gels and blots, and developing of x-ray or photographic film or prints.
You have full control over washing steps of your Western, Northern, Southern, Coomassie
Blue and Silver staining. You decide which runs are automated and which are handled
conventionally. Unattended washing can save countless hours of tedious
monitoring for a busy lab.
We currently offer inexpensive Imaging System for both bright light and fluorescent microscopy. The system is
based on high resolution Sony CCD camera and imaging software developed in NIH. It is perfect for image documentation, FISH, images
superimposition and even 3-D reconstruction. The cost for the system is only $4,800, for systems shipped installed in the
computer - $7,395, and for the system including the computer and the fluorescent microscope - $14,200. See an
example of
fluorescent image obtained using our microscope. The image is the result of superimposition of two
images obtained with included filter sets for FITC and DAPI. The subject is BPAE cells stained with FL phallacidin for
F-actin and DAPI for nuclei (Molecular Probes).
Inexpensive epi-fluorescence microscope
comes complete with a set of filter cubes for common probes, eight fluorescence objectives from x10 to x100 and phase
contrast ($6,890). Trinocular microscopes could be configured with complete imaging systems (from $4,800.) Filters for other
probes are available, including multi-band filter sets. Could be used for FISH and other applications.

An ergonomic inverted microscope with motorized control of the stage and focus
movement, which eliminate the need to elevate and to pool your arms to reach the
microscope handles. Allows to position the microscope into remote areas for control from the
distance - sterile rooms, for example.
CONTROLLED ENVIRONMENT CLOSED IMAGING CHAMBER
Could be
used with four standard 25 mm glass coverslips to form optical quality surfaces
on the bottom and on the top of the media and above the gas mixture to control
the atmosphere (pH) and to prevent condensation. Easy to assemble. Includes
stainless suction tubing for continuous media exchange and luer connector for
gas mixture input (from a cylinder with CO2/O2, for
example). Easily converts to sealed or open chamber. The chamber has separate
compartments for solution inflow and outflow to provide smooth perfusion and to
prevent bubbles from coming into the working area. Consider adding a miniature perfusion
system. Fits into heating stages of our temperature controllers.
