SAR-830/AP Small Animal Ventilator 小動物呼吸器
可適用於齧齒類動物 The SAR-830 series ventilators are our most popular small animal ventilators! Their legendary reliability rests on simple principles of operation and robust construction. Tidal volumes are generated by gating a known airflow into the lungs for a set inspiratory time. Only three controls — respiratory rate, inspiratory time, and flow rate are necessary to produce tidal volumes and respiratory rates over a wide range. Model SAR-830/AP (shown above) has the additional feature of pressure-cycling, where the lungs are always inflated to a set pressure on each inspiration. All models are available with Isoflurane or Halothane anesthesia. Choose your model: SAR-830/P -- Volume or pressure-cycled operation. Has built-in airway pressure bar-graph, and analog pressure output signal. Requires a pressurized source of air, oxygen, or anesthetic mix to operate. SAR-830/AP -- Volume or pressure-cycled operation, with internal air pump for self-contained operation.. Has built-in airway pressure bar-graph, and analog pressure output signal. Accessories: All models are expandable to larger animals, or multi-animal setups through a simple expansion connector. |

BP-100 Blood Pressure Monitor 血壓監測儀
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. |
Create your own gas blends 氣體混和裝置
|
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. |
CO2 Monitor for mice 小鼠用二氧化碳監測
|
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. |

MRI-1 Ventilator 核磁共振用呼吸器
How it works: The MRI-1 operates on the flow-time principle: an inspiratory airflow is established and gated into the animal for a known time, thus producing a known volume. This approach provides extraordinary flexibility — a wide range of volumes, breaths-per-minute, and I/E ratios are possible with no hardware changes, and using just three front-panel controls. For small animals, respiratory airflow is provided by an internal airpump. Alternatively, an external pressurized gas source can be attached (oxygen or anesthetic gasses). The remote pneumatic valves do the actual airflow switching. By locating these valves close to the animal (including inside the magnet bore if necessary), dead-space and tubing compliance are minimized. A range of valves is now available for animals ranging from mice to pigs. Rodent-size valves are supplied standard, and larger valves can be purchased later as required. Operation: Setting up and operating the MRI-1 is easy. Flexible tubing connect the control unit and the valves, providing respiratory airflow and pneumatic control pressure to the valve. Only three controls are required: respiratory rate is set in breaths/minute; the flow rate is set using the front-panel flowmeter (and measured internally by a mass flowmeter); and the percent inspiration is set to establish the ratio of inspiration to expiration time (I/E ratio). All respiratory parameters are shown on the front-panel LCD display. The tidal volume and minute ventilation reflecting the current settings is also continuously displayed, and can easily be changed by adjusting the flow rate. Expandable: The MRI-1 can also be used in other than magnetic environments. Because of the non-electrical nature of the ventilation valves, this unit is particularly well suited to sensitive electrophysiology recording situations. Besides the standard miniature pneumatic valves, the MRI-1 also accepts any of the solenoid valve assemblies available for the popular SAR-830 series ventilators. Using the MVA-4 multi-valve expander, it is also possible to ventilate several rodent-sized animals simultaneously using just one MRI-1 as the control unit. The external valves operate synchronously, but tidal volumes are independently set by varying the flow rate to each valve assembly. Installation requirements: A source of compressed air (approx. 20-50 psi) is required for operating the pneumatic valves. This is attached to the rear panel of the unit, and the pressure is internally switched on or off as required for remote valve operation. All models feature switchable 120/240VAC operation. |
