Rotolavit

Automatic Cell Washing System 
for Serological Testing

In blood banks and transfusion centres, it is routine practice to test the compatibility between donor and recipient prior to every blood transfusion. The Rotolavit cell washing system is ideal for this viral application. The washing process is carried out automatically. The appropriate quantity of saline solution is filled equally into 12 or 24 tubes, depending on the rotor, and mixed with a previously pipetted drop of blood. It is then centrifuged and the supernatant is decanted. The washing cycle is repeated several times and the anti-human globulin (Coombs) serum is then added manually, in order to assess possible agglutination following the final centrifugation.

The washing cycle process is repeated automatically, allowing uü to 9 sequenced washing cycles to be programmed freely.

A washing cycle includes the following steps:

1. Filling the saline solution
2. Centrifuging at (usually) 3.500 min^-1
3. Decanting the supernatant
4. Resuspending the sediment (between cycles only)
