The AFT27 3.0 Liter Calibration Syringe is certified to have a volume that meets or exceeds an accuracy of 0.5% of the total displacement volume (3 liters ±0.5%).
This adjustable aluminum calibration syringe is shipped with the volume locked to 3.0 L and BIOPAC templates and software settings are set for 3 L. The locking collar and graduated rod allow users to select other calibration volumes, from 0.5 Liters to 3.0 Liters. The aluminum syringe has a universal connector and works with BIOPAC’s AFT11D flexible coupler (35 mm OD, 35 mm OD).
(The AFT27 3-L Calibration Syringe replaces the AFT26 2-L Calibration Syringe.)
The STMTHERM is a thermal stimulator that can deliver both hot and cold temperature stimulation to a subject. The STMTHERM can be used to identify participant thermoreceptor response thresholds for a variety of applications. The STMTHERM consists of two parts, the Stimulator Control Unit (SCU) and the included Thermal Stimulation Transducer (TSD191 Thermode) to deliver temperature […]
Recent studies in Psychophysiology, EMG, ECG and PPG measurement utilizing BIOPAC software and hardware: Fight or Flight (Reflex Response Time) “Fight or flight” is a physiological response that occurs due to a perceived threat to survival. It can physiologically be observed through an increase in heart rate, respiratory rate, blood pressure, oxygen availability, and other mechanisms. In […]
HRV, EMG, and EEG studies using BIOPAC hardware and software include: DON’T STRESS Humans encounter various stressful situations everyday at work, home, and school. Such stress when experienced at high degrees and/or for a long duration of time could lead to cardiovascular diseases, cognitive dysfunctions, and psychological disorders. This study examined the validity of a novel physiological measurement […]
