仪器简介：
New development based on more than 10 years of experience in bubble
pressure measuring technique. Many new instrumental details have been
published recently, such as the determination of bubble time characteristics
from the gas flow signal. To reach the extra short times of milliseconds and
less, the special measurement routine of Fainerman is applied.
Can work as stand-alone, graphic display on board.
Unique instrument for measurements down to 0.1 milliseconds.
The BPA-1S represents the high end instrument of bubble pressure
tensiometry, and the BPA-1P is its simplified version.
Software
BPA-1S can operate as stand-alone
instrument. It stores data on board for 180
measurements which can be downloaded to
a PC (both RS232 and USB port on board).
The software allows graphical display of
several measurements for comparison.
Graphics with various zoom functions
supports the visual analysis of the data.
Export as text file or directly into MS Excel.
Unique instrument for very short adsorption
times down to 0.1 milliseconds due to the
application of the Fainerman measuring routine. Automatic and manual
determination of the critical flow rate. Required small bubble volume and deadtime
possible due to specially designed capillaries.
Fields of Application
surfactant science pharmacy
ink jet printing cosmetics
coating technology food technology
foam and emulsion technology medicine and biology
detergency ecology
