iWorx provides integrated physiology teaching kits and a full range of advanced systems and components for physiology research.

 
iWorx IX-214  是一個堅固耐用且可信賴的四頻道數據紀錄系統。其外觀是由壓縮鋁一體成型，因此可避免學生接觸到這些內藏的控制和調整元件。在大部份的實驗中，設定是自動且簡單的。只需要點一下滑鼠就可把生理訊號收集記錄起來，藉由軟體強大的分析功能可以針對各種不同性質的實驗搭配不同的Transducers來做不同的分析，如:EEG、ECG、EMG...等等。IX-214內建了兩組針對EEG、ECG、EMG的Amplifier，另外有兩個頻道可以接受任何的Transducers來搭配您的實驗需求，此外也可接受pH meter、spectrophotometer、Blood Pressure...等等和其他實驗室儀器。
IX-214也包含一個功能完全的內建刺激器。此刺激器可以應用在各種不同的人類和動物實驗中。此外，IX-214是藉由USB和電腦相接。其可提供總共100kHz的sampling rate。這樣的頻率已足夠適用在各種不同的教學實驗中。

 
iWorx IX-118  是一個快速且高解析度的數據擷取系統，幾乎可適用於所有研究實驗室中所需要的研究資料紀錄。它提供八個類比輸入、八個數位輸出、四個數位輸入和兩個DACs。
類比輸出：iWorx IX-118提供兩個＋/－10V的類比輸出(DACs)。每一個可以獨立設定程式也可以同步(synchronized)一起運作。每一個刺激的基本參數，例如pulse width、頻率和震幅都可利用軟體改變。標準的protocol包含了pulse、train和step waveform的設定。此外每一個標準的protocol都能在穩定的狀態下維持住電壓，因此很適合voltage clamping的應用。
解析度和雜訊：
iWorx IX-118以16 bit A/D conveter去取樣數據。任何的輸入訊號其雜訊都是少於1mV。這樣小的雜訊使得118能紀錄從10mV到10V的訊號而不需要另外的外部gain。
數位輸入/輸出：
iWorx IX-118有提供八條數位輸出線。這些數位輸出connector是工業標準的BNC規格，所以不需要特別訂作。此外也提供四條數位輸入線可和外部trigger搭配使用。
速度：
iWorx IX-118是一個快速的紀錄器。使用單一頻道時能以每秒收集100K樣本的速度來擷取數據。在使用八個頻道下每一個打開的頻道能每秒收集10K的樣本。
除了上述特色外，它還包括使用USB介面和電腦連接、體積小不佔空間方便移動和放置等特色。 

   
iWorx ETH-256
iWorx ETH-256是一個常用的放大器可應用於一般目的的生命科學研究。它的高輸入阻抗和高CMR使得它能忠實地在低雜訊下紀錄生物電位如ECG、EMG和EEG。同時也可將來自strain gauge type傳導器的訊號如力量、位移和壓力輸出。
在50mA的電流下每一個頻道可以提供±5.0V的興奮電壓，而這樣的電壓能滿足各式常被使用的傳導器。此外客戶也可指定adapter cables和Grass、Gould或HP的感應器相容。
iWorx ETH-256提供八個gain設定包括×1、×5、×10、×50、×100、×500、×1000、×5000。訊號可以利用低和高頻通過過濾器來進一步處理。這些的頻率可以用面板上的按鈕來決定。高頻通過過濾器可用來測量生物電位，它可設定在DC、0.03、0.3、3四種不同的頻率。低頻通過過濾器通常用來限制高頻率的雜訊其有5、50、150、2000、10000Hz可選擇。
iWorx ETH-256的每一個頻道可以被當作是一個橋式傳導器放大器或是一個生物電位放大器來使用。在橋式模式中 iWorx ETH-256放大器的10G歐姆輸入阻抗和differential input使得ETH-256能接收來自力量、位移或是壓力傳導器所傳來的訊號。此外許多來自電熱調節器、pH電極和其它各種可變電阻裝置的訊號都可以輸入至ETH-256。
在生物電位模式下iWorx ETH-256可視作為一個低雜訊AC coupled preamplifier來記錄生物電位。此外iWorx有提供一個三導程的纜線和iWorx ETH-256相接，讓使用者可以用來測量ECG、EEG和EMG。 
   

iWorx ETH-401
 
iWorx ETH-401是一種橋式放大器，它提供四個頻道的excitation power、gain和雜訊過濾。此外它展現出低系統雜訊和offset，使得它適合和高解析度的數據擷取系統一起使用。ETH-401可以做為一個介面將一些低頻寬的傳導器如測量力量、血壓和位移的Transducers和數據擷取系統如IX-118做連接。ETH-401上的gain control是非常簡單直接的。在DIN-8 connector中有一個已經設定好的電阻器來設定gain。iWorx傳導器會針對測量而設定ETH-401到最佳的gain值。然而這樣的設定並不會限制ETH-401和其它非iWorx的Transducers一起使用。許多非iWorx的Transducers可以修改和ETH-401一起使用。
iWorx ETH-401是一個本來就低offset的儀器。這樣的儀器和具有低offset的橋式傳導器再搭配高解析度的118數據擷取系統一起使用大大地將offset的控制需要減到最小。因為ETH-401是被鋁完整地封包，因此很堅固耐用也可增加對雜訊的免疫。同時它的體積小且底部有小的腳架，因此可以與不同的儀器堆疊起來減少實驗體積的需要。

Cardiac Hemodynamics Organ and Tissue Bath Studies Isolated Perfused Heart Epithelial LabScribe Software

Cardiac Hemodynamics Research

Hemodynamics is the study of the dynamic behavior of blood as it flows around the heart, the lungs and the body. Pressure is generated in various parts of the heart as a result of this movement. These pressures can be measured and monitored through catheters whose tips are placed in the atria, pulmonary artery, or systemic arteries.

Hemodynamic studies require the measurement of pressure, flow, and electrical signals from the heart, and electrical signals from nerves, such as the vagus. iWorx has everything you need for research studies in hemodynamics, and associated studies in cardiac electrophysiology and cardiopulmonary function.

Unique Labscribe2 Software Saves Hours in Data Extraction Time
Using LabScribe's unique Regions of Interest and AutoMarking capabilities, you can easily record and extract data of interest, then export to your choice of analytical programs. Additionally, powerful built-in analyses; let you script custom routines using a choice of any scripting languages (including Matlab, Python, Dadisp Labview and even C++); or easily export data to Excel or other analytical programs. LabScribe's versatility saves hours in data extraction time.

iWorx Features for Cardiovascular and Hemodynamic Recording

Online Analysis
LabScribe2 software can calculate rate, systolic, diastolic and mean pressures, as well as dp/dt and integral from any raw data input in real time. All of the same functions can be applied offline, too.

Offline Analysis
All of the online functions can be applied offline. In addition, a series of functions applied from the Analysis window can be used to reduce raw data. Functions operate on a selection of data and return a single value, which can be written to the LabScribe2 Journal. Currently supported functions include: T1,Y1,T2,Y2,T2-T1 Y2-Y1, Maximum, Minimum, Maximum-Minimum, Mean, Mark, Count, Units, Standard Deviation, RMS, Maximum dV/dt, Minimum dV/dt, Mean dV/dt, dV1/dt, dV2/dt, Area, Integral, Absolute Value of Integral. Analysis window functions used in conjunction with the LabScribe2 Find command, can automatically analyze the entire record.

A unique Calculations Function allows the user to identify and make measurements from characteristic points of an ECG or blood pressure waveform.

Input/Output
The built-in stimulator allows delivery of a single, continuous, or train of pulses. Pulse durations, frequencies and amplitudes can be changed as the protocol is being delivered. The software also offers full control of digital I/O lines that can be used to count events, or control devices in the lab environment.

Display
The LabScribe2 software allows you to easily convert voltage to real units, such as mmHg or percent for pressure or flow measurements, respectively. The display allows you to toggle between a preferred Y-axis scaling (between 40 and 140 mmHg, for example) and the best view as determined by the AutoScale feature. Alternately, you can zoom-in or zoom-out by factors of two with a single mouse click. In a similar fashion, X-axis scaling can be expanded or compressed by factors of two with a single click.

Real Time Annotations
While recording, you can mark your data with text messages. These marks are searchable and appear in the field of data to which they apply. Marks are time locked to the record and can be used to Go To any marked region of the data.

Data Reduction
Data can be analyzed and reduced in the Analysis window. Here, selections of data can be averaged and written to a report. For example, the software can be instructed to break the record up into five-minute pieces, determine the average systolic or average heart rate for the data in each segment, and write those values to a report.

XY Window
Any two channels can be displayed in XY format, online or offline. LabScribe2 software supports area measurements and segment slopes from such plots. And, of course, you can save the plots as pictures or text.

Export
All recorded data can be exported to either a text file or a picture (.png) making reports or posters much easier to create. Of course, you can always print your data from any window at any scale.

The experiments in the manual are designed to teach students about the properties of membranes and their potentials, action potentials, synapses, signal integration, synaptic potentials, ganglions, and receptor potentials. The manual also includes tutorials about the electrical circuits of excitable tissues and the instruments used to record from excitable tissue. The manual is written for use with the new LabScribe2 data recording and analysis software, and it includes a tutorial experiment designed to acquaint users with the features of LabScribe2 that will be used in the other experiments in the manual.	Full Size Image LabScribe2 Main Window A recording of two compound action potentials (CAPs) displayed on the LabScribe2 Main window. These CAPs were triggered by a pair of suprathreshold stimulus pulses delivered in rapid succession. The stimulus pulses were far enough apart that all the fibers in the nerve fired a second time, as indicated by the amplitude of the second CAP being the same height as the first CAP. This result occurred because all fibers were out of their refractory periods. Full Size Image LabScribe2 Analysis Window A recording of a compound action potentials (CAP) displayed on the LabScribe2 Analysis window. This CAP was triggered by a suprathreshold stimulus pulse. The values for the measurements taken from the CAP using the cursors and the functions are displayed in the Journal window next to the data display window.
