How do I calibrate a Micro Oxygen Electrode?
Electrode Assembly and Preparation Remove the acrylic housing from the Oxygen electrode by unscrewing it from the electrode body. This housing, with affixed Teflon membrane, does not contain the necessary oxygen electrolyte solution. Add oxygen...
How can a Microelectrodes test probe sold by ADInstrments be sterilized for human use?
The complete line of Microelectrodes products offered by ADInstruments can be sterilized with standard gas sterilization methods as long as the temperature is not allowed to exceed 140 °F (60 °C). An example Ethylene Oxide (EO) sterilization...
Do the MLT7006 and MLT0015 isotonic transducers connect to ADInstruments Quad and Octal Bridge Amplifiers?
The MLT7006, MLT0015 and some 3rd party transducers (ie from UGO Basile) DO NOT operate with ML118 Quad Bridge Amp or ML119 Octal Bridge Amp (the ML118 and ML119 are now discontinued). The MLT7006 and MLT0015 isotonic transducers require the ML221...
What additional features are present in LabChart when the GLP Client software is active to meet FDA guidelines?
When LabChart is operating in GLP mode (i.e. the GLP Client software is active): A digital signature must be provided when saving data files. An un-editable audit trail is automatically created. Users are prevented from cutting and pasting or...
What is the difference in gain between the ML140 Spirometer and ML311 Spirometer Pod?
The pressure sensitivity of the spirometer is 0.5 V/inch H20. For Spirometer pods with serial numbers, the pressure sensitivity of the pod is 10 mV/inch H20 and there is a gain in the pod circuitry of (50 000/680 + 1) which corresponds to 75, such...
Can surgical adhesives or common super glues be used to fix a Millar Mikro-tip catheter to a vessel?
Surgical adhesives and off-the-shelf superglues will not damage the catheter initially; however, Millar and ADInstruments strongly recommend against their use for repeated, acute catheter implantation . This recommendation is due to the difficulty in...
Why is LabChart 8 for Windows prompting me to reactivate the software when the computer is docked or undocked from its docking station?
LabChart 8 for Windows uses the computer's MAC address to generate an 'Installation ID' to activate the software with. 'LAN/WLAN switching' docking protocols can cause issues with the software activation/registration when they are enabled on laptops...
Handling When removing and replacing a membrane as well as when calibrating or making measurements, be careful not to apply pressure against the internal electrode. Any excessive pressure against the internal electrode can cause the electrode to...
What can I do about excessive room noise during Earthworm Action Potential recordings?
Many factors can contribute to noise during Earthworm Action Potentials experiments. Most noise can be reduced or eliminated by turning off overhead fluorescent lighting and moving the earthworm preparation and Bio Amp Cable away from computer...
Why do I have residual flow from the Gilson peristaltic pump when the STH Pump Controller is powered off?
A problem may arise with the generation of residual flow from the Gilson peristaltic pump when the Gilson pump remains switched on but both the PowerLab and STH Controller are switched off (with the STH Controller remaining in "Run" mode). To stop...
What are the cleaning instructions for the Electro-Caps for EEG?
Patient Cleanup: Remove the cap, ear electrodes, and body harness when the EEG recording is finished. Wipe the patient's forehead and ears with a gauze square. Lightly wipe the gauze square over the hair. Brushing or combing the hair will remove all...
Yes the specifications for the two units actually the same. The LDF specifications published on the Oxford-Optronix website are not be relied on as they are based on earlier instruments. Further, BioPac appear to source their LDF instrument from...
You can specify the time at which the first sample in the file occurs by manually entering a time value within the .txt file. The time needs to be in a form that LabChart understands, and the steps to do this are as follows: 1. Calculate the desired...
