Thermo Scientific™ Slide-A-Lyzer™ Dialysis Cassette Accessories are syringes and buoys for loading samples and floating the cassettes in dialysate.

These accessories facilitate use of Slide-A-Lyzer Dialysis Cassettes. Three different sizes of syringes with 18-gauge beveled-tip needles enable efficient injection of samples into the various sizes of cassettes. The syringes also enable accurate and complete recovery of samples following dialysis.

Three flotation buoys enable Slide-A-Lyzer Dialysis Casettes to be suspended in buffer or other dialysate. The reusable buoys are made of low density polyethylene (LDPE). For the 0.5 and 3mL cassette sizes, single-cassette and 10-cassette buoys are offered. The 12mL cassette is wider than the other two sizes and requires its own model of buoy. The 30mL Slide-A-Lyzer Dialysis Cassettes contain their own air chamber and do not require use of a float buoy.


  • Reusable – polypropylene syringes with stainless steal needles and the LDPE float buoys are easily washed and reused many times

  • Complete – these are the only two kinds of special accessories one needs for trouble-free use of Slide-A-Lyzer Dialysis Cassettes
