1.2 General Recommendations
Indications for Use
The Helmer UltraCW®II automatic cell washing system is intended to be used for the washing portion of routine blood bank and
laboratory procedures calling for washed red blood cells such as antiglobulin testing, ABO compatibility, Rh, cross matching and
anti-body screening.
The UltraCW®II automatic cell washing system should be operated by a trained individual, such as a clinical laboratory technologist
or similar education, as determining whether desired results have been achieved is subjective and dependent upon user
preparation of blood sample, and parameter selection/adjustment.
General Use
Allow the cell washer to come to room temperature before switching power on.

4 Programming
One or more individual processes make up a program. A program can include up to 20 di󰀨erent processes, but only one Loop
process can occur within a program.
4.1 Process Descriptions
Spin Process
During the Spin step, the rotor accelerates to the selected speed, spins for the
specied time, then stops quickly. This step separates unwanted particles and
creates a “button” of red blood cells at the bottom of each tube. The quick stopping
prevents the re-suspension of the red blood cells and dislodging of the red blood
cell button.
The number of revolutions per minute is adjustable from 0 RPM to 3500 RPM.
The time duration is adjustable from one second to two hours (0:00:01 to 2:00:00).
The default values are 3500 RPM and 30 seconds.
Fill Process
During the Fill process, the tubes containing cells are lled with the desired
amount of saline solution. As the rotor spins at 1100 RPM, saline is pumped from
the reservoir through the ow meter to the saline dispensing nozzle. The nozzle
directs the saline solution into the rotor, then the ll ports direct the saline solution
into the tubes. Saline solution enters the tubes in a direct stream to maximize
cell re-suspension
The number of revolutions per minute is adjustable from 0 RPM to 2500 RPM.
The ll volume is adjustable fro 0.1ml to 10ml per tube. The default values are
800 RPM and 3.0ml.
Down Process
During the Down process, the rotor spins at 2000 RPM for the specied time.
The drops clinging to the tube sides are forced to the bottom of the tubes, thereby
increasing the sample yield.
The number of revolutions per minute is adjustable from 0 RPM to 3500 RPM.
The time duration is adjustable from 0 seconds to 20 seconds (0 s - 20 s) .
The default values are 2000 RPM and 5 seconds (5 s).
Agitation Process
During the Agitation process, the rotor accelerates then stops frequently and briey,
disrupting (breaking apart) the cell buttons.
The number of shakings are adjustable from 0 times to 500 times (0x - 500x).
The default value is 15 times (15x).

Helmer Scientic Automatic Cell Washing System - UltraCW II Operation Manual
360386/D 11
Decant Process
During the Decant step, the rotor rapidly accelerates to the specied speed then
decelerates, allowing the tubes to move back to the neutral position so the rotor
lock can engage. The rotor spins in the opposite direction at the specied speed,
while the rotor lock holds the tubes at a slight negative angle. Waste solution is
expelled from the tubes by low centrifugal force, while virtually all the cells are
retained in the tubes in the form of red blood cell buttons. The waste solution is
directed to the drain hole in the bowl by the drainage system. The spent solution
ows out of the cell washer, into the drain tubing, to the waste container or
sanitary drain.
The number of revolutions per minute is adjustable fro 0 RPM to 1500 RPM.
The default value is 370 RPM.
Loop Process
The Loop process allows one or more previous processes to be repeated. Only
one Loop process can be included in a program.
The number of loops is adjustable from 1 to 100 times (1x to 100x). The selected
number of loops includes the initial run of the process(es) included in the loop
(e.g. selecting to loop a process 3 times means that process will run a total
of 3 times).
The default value is 2 times (2x).
Check Process
The Check process allows a program to be paused after one or more processes
in the program have run. Once the previous process(es) has nished, the Check
process will cause the program to be paused and the lid to open. This allows the
user to check the tubes and/or add other uids. The program will continue once the
lid is closed.
