Regenerated cellulose dialyzer ED300 Xpress Equilibrium

plate

Overview
The ED300 Xpress Equilibrium Dialyzer is designed for high-throughput processing of clinical samples for measurement of free hormones (testosterone, estradiol, cortisol, FT3, FT4). Supplied ready-to-use in a 96 deep-well plate configuration, it contains 12 cartridges with 8 sample positions each. The cartridge design enables loading and removal of samples and dialysate without cartridge extraction. SBS-compatible footprint facilitates integration with automated liquid handling workstations used in clinical and research laboratories.

Key features

• Optimized for 50–300 µl sample volumes
• Delivered in 96 deep-well plate format with 12 cartridges (8 samples per cartridge)
• Load and remove samples and dialysate buffers without removing cartridges, reducing handling time
• SBS compatible for automated liquid handling systems and robotic workstations
• Low-binding regenerated cellulose membrane (glycerol-treated to prevent embrittlement; trace elements such as sulphides and heavy metals may be present)

Ordering options (examples)

• Dialyzer Cartridge, 8 tests — individual cartridges (multiple MWCO options available)
• Dialyzer Kit, 96 tests — full kit option including plate and cartridges (multiple MWCO options available)
