Designed to accommodate up to 0.5 mL of fluid, this ready-to-use cassette completely eliminates the tedious, leak-prone process of knotting traditional dialysis tubing. It features a low-binding regenerated cellulose membrane with a strict 3,500 Dalton Molecular Weight Cut-Off (3.5K MWCO), ensuring that small peptides and target proteins are securely retained while unwanted salts, crosslinkers, and small molecular contaminants diffuse freely into the exchange buffer. The G2 architecture incorporates built-in air chambers for self-floating buoyancy and a self-sealing syringe port for uncompromised sample loading and retrieval.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Performance and Design\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eRegenerated Cellulose Membrane:\u003c\/b\u003e The 3.5K MWCO membrane provides exceptional chemical compatibility and extremely low non-specific protein binding, ensuring maximum yield of dilute or highly valuable macromolecules.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSelf-Sealing Syringe Port:\u003c\/b\u003e Researchers can safely load and extract their sample using a standard laboratory syringe and needle, entirely bypassing the sample loss associated with clamping or knotting bulk tubing.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMaximized Surface Area:\u003c\/b\u003e The flat, dual-membrane rigid frame maximizes the surface-area-to-volume ratio, significantly accelerating the diffusion rate and reducing total dialysis time to just a few hours.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSelf-Floating Architecture:\u003c\/b\u003e The integrated air chambers ensure the cassette floats vertically in the dialysis buffer without the need for cumbersome external buoys or flotation rings.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCatalog Number:\u003c\/b\u003e 87722\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eProduct Line:\u003c\/b\u003e Slide-A-Lyzer G2\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eVolume Capacity:\u003c\/b\u003e 0.5 mL\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMolecular Weight Cut-Off (MWCO):\u003c\/b\u003e 3.5 kDa (3,500 Daltons)\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMembrane Material:\u003c\/b\u003e Regenerated Cellulose\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePackaging:\u003c\/b\u003e Box of 10 Cassettes\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eKey Benefits \u0026amp; Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePeptide \u0026amp; Small Protein Recovery:\u003c\/b\u003e The tight 3.5K MWCO is specifically chosen for dialyzing low-molecular-weight proteins and peptides that would otherwise escape through standard 10K MWCO membranes.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eBuffer Exchange \u0026amp; Desalting:\u003c\/b\u003e The standard choice for rapidly removing imidazole, reducing agents, or high salt concentrations from purified fractions prior to downstream functional assays or lyophilization.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eHigh Volumetric Recovery:\u003c\/b\u003e The rigid internal geometry allows users to withdraw the sample with a syringe needle without puncturing the opposite membrane, routinely delivering macromolecule recovery rates exceeding 95%.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eWorkflow Efficiency:\u003c\/b\u003e Arrives cleanroom-assembled and ready to use, completely bypassing the hours of boiling and chemical pretreatment required for rolls of dry dialysis tubing.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\u003cp style=\"margin: 0; font-size: 0.8em;\"\u003e\u003ci\u003eAll product names, logos, and brands are property of their respective owners.\u003c\/i\u003e\u003c\/p\u003e","brand":"Thermo Scientific","offers":[{"title":"Default Title","offer_id":44789856370940,"sku":"6054","price":37.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/thermo-scientific-slide-a-lyzer-cassette-05-ml-35k-mwco-pack-of-10-cassettes-other-thermo-scientific-899060.jpg?v=1713483589","url":"https:\/\/lifesciencestrading.com\/products\/thermo-scientific-slide-a-lyzer-cassette-0-5-ml-3-5k-mwco","provider":"Life Sciences Trading","version":"1.0","type":"link"}
