Notice
to our Customers!
We are
moving to new facilities on August 25th, 2008. Our phone and fax
lines will be disrupted for a day or two at that time. Please feel
free to email us during this period. Thanks for your continued support!
The completion of
construction of our new and improved offices, development labs, and
shipping facilities will improve every aspect of our operations. We look
forward to serving you in the near future. Watch this space for new
product introductions! |

Thank
you for making the Society for Neuroscience 2007 meetings in San
Diego a major success! We enjoyed meeting so many of our old
friends, and making new ones. We believe our customers are always the best
source for new and useful ideas, and we intend to make the most of them in
the years ahead.
If you
missed any of our new product introductions, we invite you to discover
them here! |

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.
End-tidal CO2 is well
known as an important indicator of respiratory status. The microCapStar
extends this important measurement to the smallest animals.
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.
