The SAR-1000 is our newest and
most advanced ventilator for mice, rats, and other small
animals. It follows in the tradition of our ever popular
SAR-830 series, which has been an international standard for
over twenty years. We incorporated the latest in digital
control and advanced sensor technology to produce our
easiest-to-use and most accurate ventilator yet. All settings
such as respiratory rate, tidal volume, end-inspiratory
pressure, I/E ratio, and more, are set directly from the front
panel. All user-settings and computed measurements (such as
Minute Ventilation) are clearly displayed on the backlit LCD
panel. An LED pressure bargraph shows instantaneous airway
pressure for easy monitoring of ventilator operation.
All CWE ventilators have a
built-in remote control interface. Our customers have come up
with a surprising variety of uses for this feature, including
synchronized gating of imaging systems, servo control of
end-tidal CO2, neural triggering, and more. The SAR-1000
retains this handy remote control port, but adds a USB
interface for additional remote setup and monitoring functions.
Optional software is available for easy-to-use remote
operation.
We are very proud to introduce
this new model, which is the result of years of development and
the welcome input of many users in labs around the world. It is
our smallest, greenest, and most sophisticated ventilator. Put
one to work in your lab
today!

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. |

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.
