We've been using 2 Hettich centrifuges for quite a few years now. They have been very reliable and run quiet. The down side is that I find them a little tricky to program, which fortunately I don't need to do that after the initial set up. (The upside to that is that my mystery tech who feels urges to tinker with stuff can't figure them out, so they leave them alone.)

I'll assume you are doing Gel testing manually. I think you are wise to convert routine ABO/Rh and Antibody screen from tube testing to Gel testing.
To QC the antibody screen test using Surgiscreen and Anti-IgG Gel card, you need a positive and negative control cell for each screen cell vial.  This can be accomplished in one (1) Anti-IgG Gel card.
To QC the A/B/D Monoclonal and Reverse Grouping card, you will need to test each reagent in the gel card with positive an negative controls (this will require a minimum of two cards). You can QC the two (2) Buffered Gel columns with anti-A + A1 cells, anti-A + B cells, anti-B + A1 cells, and anti-B + B cells using the same two A/B/D Monoclonal and Reverse Grouping cards.
You could use the A/B/D Gel card to confirm all donor unit types or you could use the A/B Gel card for non-group O Rh positive units, the Anti-A,B Gel card for all group O Rh positive units, and use the A/B/D Gel card for all units labeled Rh Negative.  All these cards would require Day of Use QC.
You could use the A/B/D Monoclonal and Reverse Grouping Gel card or the A/B/D Monoclonal Grouping card for Cord Blood testing.  These cards will not detect all weak D's. You will have to run Weak D testing on all Cord Bloods initially classified as Rh Negative.
There are other options based on your workload.
