¡áƯ ¡ (Features ) Dialysis Tubing Closures Using resealable closures is the preferred method for sealing dialysis tubing without the risk of leaking. Tied knots are nearly impossible to open & re-seal and often result in damaged, leaking membranes. Spectrum offers two classes of Dialysis Tubing Closures, Universal Closures for use with all membrane types and specialized Spectra/Por¢ç Closures with additional functional benefits for use only with Standard Grade tubing.
Spectra/Por Closures for Standard RC Membrane Only * Spectrum offers 3 different functional closure types (Standard, Weighted & Magnetic Weighted) as well as a functional combination pair of closures (Standard & Weighted). * For best results, select a pair of closures that has a sealing width 4 to 10 mm longer than the flat width of the dialysis tubing. This assures a proper seal without membrane tearing. Standard Closure Type * Since Spectra/Por Standard Closures float, they aid in buoyancy and vertical orientation when applied to the tubing top end. * Autoclavable and available in a variety of colors for easy sample identification. * Product Specifications - Functional Benefit:Sample buoyancy & vertical orientation - Membrane Types:Standard RC only - 5 Sealing Widths:12 mm, 23 mm, 35 mm, 55 mm, 75 mm - 4 Colors:Orange, white, green, blue - Qty:10/pkg - Material:Polypropylene - Temperature:0 - 121¡ÆC (autoclavable)- Ordering Information: Standard Closures click on Part No. to add to cart
Weighted Closure Type * Autoclavable, Spectra/Por Weighted Closures encase an acid- washed, fluorocarbon coated, stainless steel bar. * When applied to bottom end of the dialysis tubing, the Weighted Closure acts like an anchor to maintain a vertical orientation of the sample. * Product Specifications - Functional Benefit: Weighted for vertical sample orientation - Membrane Types: Standard RC only - 5 Sealing Widths: 12 mm, 23 mm, 35 mm, 55 mm, 75 mm - 1 Color: White - Qty: 10/pkg - Material: Polypropylene - Temperature: 0 - 121 ¡ÆC (autoclavable)
Magnetic Closure Type Autoclavable Spectra/Por Magnetic-Weighted Closures contain a magnetic fluorocarbon coated stainless steel bar, eliminating the need for conventional stir bars. Applied to the bottom end of the dialysis tubing, this closure provides complete submersion and gentle rotation of the sample on a stir plate. Product Specifications - Functional Benefit: Weighted & magnetic for submersion & stirring - Membrane Types: Standard RC only - 5 Sealing Widths: 12 mm, 23 mm, 35 mm, 55 mm, 75 mm - 1 Color: Red - Qty: 2/pkg - Material: Polypropylene - Temperature: 0 - 121 ¡ÆC (autoclavable) Ordering Information: Magnetic Closure click on Part No. to add to cart
Paired Standard & Weighted Closures * The ultimate sample buoyancy and vertical orientation can be achieved by applying both a Standard and a Weighted Spectra/Por Closure to opposite ends of the same dialysis tubing. * The Paired Closures are autoclavable. Product Specifications - Functional Benefit: Buoyancy and vertical orientation - Membrane Types: Standard RC only - 5 Sealing Widths: 12 mm, 23 mm, 35 mm, 55 mm, 75 mm - 2 Colors: Orange (standard) and White (weighted) - Qty: 10 standard & weighted pairs/pkg - Material: Polypropylene - Temperature: 0 - 121 ¡ÆC (autoclavable) Paired Closure Ordering Information: click on Part No. to add to cart
