We
invite you to stop by our exhibit at the Society for Neuroscience 2009
meetings in Chicago, Illinois (Booth 1463)! We have some exciting new products to
show you, and of course just enjoy meeting you.
If you
miss any of our new product introductions, we invite you to discover
them here! |

4-Channel programmable stimulator
 |
Model
FNS-4 Four-channel Stimulator is the latest addition to our popular
real-time programmable stimulator line. Complete user control of the
constant-current stimulus waveform is provided by a PC-hosted Labview (or
other) control program. All outputs feature medical-grade isolation.
Completely redesigned architecture allows true synchronous operation
across groups of channels. The high-speed programmability allows fast,
closed-loop stimulation in response to external signals.
If you need more than four
channels, please consider our FNS-16 sixteen channel instrument
with the same features! |
microCapStar
CO2 Monitor for Mice
The microCapStar End-Tidal Carbon Dioxide Analyzer
provides accurate end-tidal or continuous measurement of expired CO2 in animals as small as mice. It features very low sample flow
(5-20 ml/min, adjustable), fast response time, and excellent stability. Respiratory rate (RR) is computed using the excursions of the
CO2 waveform. The CO2 and RR measurements, as well as a trend plot of the end-tidal values, are displayed on the graphics LCD screen. New
internal software allows user-adjustable ETCO2 and RR averaging, as
well as higher resolution measurement.
End-tidal CO2 is well
known as an important indicator of respiratory status. The microCapStar
extends this important measurement to the smallest animals.
Blood Pressure Monitor for small animals
The BP-100 Blood Pressure Monitor is an accurate, easy-to-use instrument for measuring direct blood pressure (BP) from small animals. It is designed to operate using standard, widely available clinical-type BP transducers (included with unit). In addition, miniature catheter-tip transducers are available for high-resolution intra-arterial BP measurements. The standard systolic, diastolic, and mean pressures are reported, along with heart rate (HR).The BP-100 features automated operation, including push-button transducer zeroing. High and low-pressure alarms are user-adjustable. A serial data output is provided for remote data collection. Analog voltage outputs for fast (continuous signal), systolic, diastolic, and HR are compatible with data acquisition systems. All computed measurements are updated every 2.5 seconds. A special fast mode can be selected, where the display is rapidly updated. This mode allows the BP-100 to be used as a general-purpose transducer amplifier for recording signals other than arterial BP.
Cycle-Triggered Ventilator control for SAR-830 series ventilators
|
|
Features and benefits:
= Complete remote control of
ventilator
= Synchronize ventilation to neural
activity
= Works with paralyzed or un-paralyzed animals
= Backup ventilator instantly
selectable
= Displays airway pressure and CO2
(if available)
= Other custom control functions
available
= Runs on any Windows PC with USB
port |
Turn your SAR-830/A or SAR-830/AP Small Animal
Ventilator into a neural-controlled ventilator. This control software,
coupled with an inexpensive USB-connected data-acquisition device, creates a
triggered ventilator synched to Phrenic nerve activity (or other inspiratory
nerve or muscle).
All that is required is a Moving Average of the
nerve activity, which is connected to the USB box. Adjustable trigger levels and
a "backup" standard ventilator are included. This system allows
complete remote-control of the ventilator.
GSM-3 Programmable Gas Mixer
This three-input gas mixer can
provide any mix of gasses for hypoxic studies or whenever custom concentrations
are needed. The GSM-3 operates in a stand-alone mode, where up to four
custom mixes are created, stored, and
instantly executed with a pushbutton press. The real power is unleashed when the
instrument is connected to a host
computer, where the provided software allows timed mixture protocols to be
easily set up and run. This allows
automated experiments where ambient gas concentrations need to be sequenced.
Comes complete with software on
CD-ROM and a serial cable.

Oxygen Analyzer
Our new OxyStar-100 O2 analyzer features excellent
accuracy and fast response. It employs the latest generation of
digital paramagnetic sensors for long, trouble-free service. Sample flow
rate is adjustable over a 10-200ml/min range. |

MRI-1 Volume
Ventilator |
Rodent valve set |
Now available!
The MRI-1 Ventilator
is a small animal ventilator specifically designed for use in MRI
environments. This volume-cycled ventilator for rodents (including mice) uses
miniature, non-magnetic pneumatic valves that can be placed close to, or
inside, the bore of the magnet. It features direct setting and readout of
breaths/min, tidal volume, and other parameters for easy setup and monitoring. A
serial data output is standard. Download a complete data sheet by clicking here.
We
now offer a complete range of valves for larger animals up to monkeys and pigs.
Customized packages are available for the injection of hyperpolarized noble
gasses for specialized imaging applications.
Coming
soon! Pressure
Control Module accessory for the MRI-1 that allows pressure-cycling of the
respiratory cycle.
Small Animal Ventilators
Shown here is our popular
model SAR-830/AP small animal ventilator. Economical and reliable pressure or volume-cycled
ventilator for mice to Guinea pigs. Widely copied, but this is the original!

TA-100 Transducer Amplifier
The
TA-100 is a compact, economical amplifier for use with all bridge-type
transducers. These include blood pressure, air pressure, force, acceleration,
etc. It has a wide gain range and sharp-cutoff filters. The built-in LCD panel
shows the actual output voltage as well as a handy bar-graph meter. It also
features a serial port for remote data collection.
