Thermo Scientific Slide-A-Lyzer Mini Float 2 Packs with 4 Floats Each

Thermo Scientific 69588 Slide-A-Lyzer Mini Dialysis Float – White, 25-Place

The Thermo Scientific 69588 is a precision-molded floating buoy designed to facilitate the high-throughput dialysis of micro-volume samples. Specifically engineered for use with Slide-A-Lyzer Mini Dialysis Units (0.1 mL and 0.5 mL capacities), this 25-place white float ensures that multiple samples can be processed simultaneously in a single buffer reservoir. The float is manufactured from a high-density, chemically resistant polymer that provides consistent buoyancy, keeping the dialysis membranes submerged at the optimal depth for maximum diffusion efficiency. Its vertical orientation prevents sample leakage and ensures easy access for pipetting. Whether performing buffer exchange, desalting, or sample concentration, the 69588 float is an essential accessory for maintaining organized and reproducible dialysis workflows in molecular biology and proteomics.

Technical Performance and Design

• 25-Place Capacity: Features a grid of 25 precisely sized apertures, allowing for the parallel processing of up to 25 separate samples in a standard laboratory beaker (typically 1 L or larger).

• Optimized Buoyancy: Calculated to keep the dialysis units floating at a specific level, ensuring the membrane is fully in contact with the dialysis buffer while the sample chamber remains safely above the waterline.

• Chemical Resistance: Constructed from durable, low-extractable materials that are resistant to common laboratory buffers, salts, and detergents used in protein purification.

• Secure Friction Fit: The holes are designed to provide a secure friction fit for the Slide-A-Lyzer Mini units, preventing them from falling out even during moderate buffer agitation with a magnetic stir bar.

Key Benefits & Applications

• Protein Desalting: Allows for the rapid removal of salts or small molecules from protein samples while processing dozens of samples at once, ensuring identical dialysis conditions across the batch.

• Buffer Exchange: Ideal for preparing small volumes of samples for downstream applications such as mass spectrometry, NMR, or electrophoresis.

• Workflow Organization: Eliminates the need for makeshift floating devices or tape, providing a professional and stable platform for sensitive micro-dialysis procedures.

• Sample Safety: The vertical floating design minimizes the risk of sample contacting the cap, reducing the possibility of contamination or loss of precious low-volume analytes.
