Groupamatic MG 50 equipment looks to be quite well adapted to suit the needs of small or medium size blood transfusion centers, in which the number of blood grouping determinations daily processed is in the range of 100 to 500. In its present configuration (after some modifications have been brought in), the MG 50 offers significant advantages which will be discussed in detail. For a batch of 58 samples tested in one hour on twelve channels a single technician is required instead of 3 to 4; sample supply of equipment is therefore made in a more regular way. In case of run interrupt a single series of 12 determinations is implicated and can be immediately checked. The whole analysis process is limited to twice 11 minutes due to the continuous agitation of discs. The tubing pump priming is automatically performed and the reagent homogeneity is better insured; the presence of dilution tubes is easily controlled. Different programs are easily interchangeable and make the use of equipment smooth. We do think that MG 50 allows a better distribution of work throughout the day and accepts emergency blood grouping requests without any special difficulty.
Groupamatic MG 50设备看起来非常适合中小型输血中心的需求，这些中心每天处理的血型鉴定数量在100至500次之间。在其目前的配置（经过一些改进之后）下，MG 50具有显著优势，将在下文详细讨论。对于在12个通道上一小时内检测的58个样本批次，仅需一名技术人员，而非3至4名；因此设备的样本供应更加规律。在运行中断的情况下，受影响的只是一系列12次测定，并且可以立即进行检查。由于圆盘的持续搅拌，整个分析过程仅需2×11分钟。管道泵的灌注自动进行，试剂的均匀性更有保障；稀释管的情况易于控制。不同程序易于互换，使设备的使用更加顺畅。我们确实认为MG 50能够在一天中更好地分配工作，并且能够毫无特殊困难地接受紧急血型鉴定请求。
