Debubbler Series
Remove Bubbles, Dissolved Gas, or Both!
Dissolved gases and bubbles in system liquids cause dispense volume
anomalies in many instruments, negatively affecting both dispense
precisionandanalytical accuracy. Nowyouhavea choiceof components
for actively removing bubbles with or without also removing dissolved
systemgases. Online VacuumDegassingoffers operating convenience,
high effciency and low operating costs compared to other common
degassing technologies.
Debubbler/Degasser
Combines Vacuum Degassing with Active Bubble Removal
Improves instrument performance — reduces downtime due to
bubble formation
Fewer false positives due to reduction of partial reagent dispenses
Easily integrates into any pump, degassing tray, or stand-alone
degassing application
For dispensing applications, removing both bubbles and dissolved
gases from the fowpath improves dispense precision and accuracy and
enhances overall systemperformance. By combining vacuumdegassing
with active bubble removal, the Systec Degasser/Debubblers both
eliminate existing bubbles and actually prevent the formation of new
bubbles by removing the dissolved gases before they can nucleate
and cause problems.
ActiveDebubbler
Remove Bubbles in Fluid Stream Before or After the Pump
Improves instrument performance — reduces downtime due to
bubble formation
Fewer false positives due to reduction of partial reagent dispenses
Easily integrates into any pump, degassing tray, or stand-alone
degassing application
In many low-pressure systems, such as diagnostic instruments,
bubbles in the fuid stream can cause false detection readings and
dispense anomalies. For these systems, the Systec Active Debubbler
captures and removes bubbles before they can affect the instrument
or the results.
Transfer-LineDegasser
Removes Dissolved Gases During Fluid Transfer
Eliminates baseline fuctuations for improved detector sensitivity
Coaxial design reduces number of connections, improves reliability
Single lumen design increases degassing reliability
Inside instruments, where space is at a premium, the Systec Transfer-
Line Degasser can be routed to deliver fuids into and through small
places. This unique degasser employs a co-axial design to remove
dissolved gases and bubbles, while the liquid is being transferred.

removal
In medical analyzers, bubbles interfere with critical volumetric reagent
dispenses and cause sample failures, wasting time and money. Because
bubbles adhere to nearly every part of a dispensing system, high velocity
or induced turbulent fow is often used to displace and discharge bubbles
from the fow stream and into a waste area. These alternative processes
waste reagents and are time consuming, unpredictable, and may additionally
require designing the system to recognize bubbles are present. Regardless
of how the systems are designed, aqueous systems will always be subject
to the laws of physics that cause out-gassing during changes in fuid
temperature, pressure, or chemicals mixture. In fuid applications like these,
debubblers are the optimal solution to capture and remove formed bubbles
to prevent sample dispense inaccuracies, and degassing is ideal to prevent
downstream bubble formation from recurring.
