Is ULTRAPURA PLATINUM chemical flow visualization hose compatible with my specific chemical and temperature range, and how can I obtain official resistance confirmation from Tubes International?

Short answer: Possibly . ULTRAPURA PLATINUM chemical flow visualization hose is formulated for broad chemical compatibility (transparent PFA inner layer + platinum-cured silicone outer) and wide temperature range (â30Â°C to +150Â°C), but final compatibility depends on your specific chemical(s), concentration, temperature, pressure and duration. What to do next: - If your medium and conditions are within â30Â°C to +150Â°C and working pressure 1â3 bar (depending on diameter), the hose material set is likely suitable for many aggressive fluids due to inert PFA inner surface and reinforced construction. - However, for definitive resistance and approved conditions of use you must contact Tubes International for official confirmation (as stated by the manufacturer). Provide them: chemical name(s), concentration, temperature, exposure time, pressure, flow regime, hose diameter, and any regulatory/sterility requirements. Ask for written chemical-resistance confirmation and any recommended fittings/installation details to avoid damage to the PFA inner layer.

Can ULTRAPURA PLATINUM chemical flow visualization hose be autoclaved or sterilized using common methods (steam, gamma, EO) without degrading PFA or silicone?

ULTRAPURA PLATINUM chemical flow visualization hose: Inner PFA and outer platinum-cured silicone are both materials commonly compatible with standard sterilization methods-steam autoclaving, gamma irradiation and EO-within their material temperature and dose limits. Silicone outer layer tolerates repeated steam cycles; PFA inner layer resists heat and chemical degradation. However, specific resistance (number of cycles, maximum autoclave temperature/pressure, gamma dose effects, EO residuals) and assembly (fittings, stainless spiral, seals) can affect performance. Tubes International must confirm validated sterilization parameters and any limitations for your exact hose diameter, assembly and intended use. Contact Tubes International for official sterilization conditions and approvals.

How do I select fittings and clamps to avoid damaging the ULTRAPURA PLATINUM chemical flow visualization hose?

To avoid damaging the ULTRAPURA PLATINUM chemical flow visualization hose when selecting fittings and clamps, follow these guidelines: - Use fittings with a smooth spigot (tail) without sharp edges, high ribs or aggressive barbs that can cut or abrade the inner PFA layer. - Match spigot diameter precisely to the hose inner diameter to ensure proper sealing without overstretching or compressing the PFA inner layer. - Prefer smooth, slightly tapered spigots that distribute compression evenly rather than pointed or serrated designs. - Use clamp sleeves or band-type clamps that provide uniform radial pressure; avoid narrow or high-profile clamps that concentrate force on a small area. - Choose clamps sized and rated for the hose working pressure (1â3 bar depending on diameter) and for the hose outer diameter including the silicone cover. - Use materials compatible with the hose (e.g., stainless steel clamps and fittings) to maintain purity and meet hygiene standards. - Avoid overtightening: tighten clamps just enough to sealâexcess torque can deform or cut the PFA layer. Consider using a torque wrench or preset torque-limited tools. - Where possible, use clamp designs with protective sleeves or liners between clamp and silicone to reduce friction and point-loading. - Ensure assembly is cleanroom-appropriate and free of particulates; inspect spigots for burrs before installation. - For use with aggressive chemicals or specific process conditions, consult Tubes International for confirmation of compatibility and recommended assembly details. These measures protect the transparent PFA inner layer, maintain aseptic integrity and preserve the visualization properties of the ULTRAPURA PLATINUM hose.

Low-pressure suction and discharge hose with a transparent inner layer made of chemically resistant PFA and a thick outer layer made of transparent silicone. Designed for various applications in the pharmaceutical, cosmetic, food, and chemical industries, where, in addition to the highest purity, aseptic conditions, and chemical resistance, observation of medium flow is required. The inner layer is made of perfluoroalkoxy polymer PFA (fluoropolymer with properties similar to Teflon), transparent, mirror-smooth, odorless and tasteless, chemically inert, meeting high hygiene requirements (FDA, USP, European EU). Reinforcement with a stainless steel spiral provides good resistance to vacuum. The thick outer layer made of platinum-cured silicone with a smooth surface features non-stick properties (the hose does not “stick”) and a low coefficient of friction. It can be easily cleaned using a mild detergent. The hose design combines the advantages of PFA with the flexibility of silicone and its temperature resistance. The hose has a small minimum bend radius, is flexible and elastic at low and elevated temperatures, resistant to cyclic bending according to ASTM D 2176 and dynamic loads. Standards and hygiene requirements: inner layer: USP Class VI, 3-A Sanitary Standards 18-03 Class I, 10/2011/EU, FDA, ISO 10993-4, -10, -11, non-cytotoxic (ISO 10993 Part 5), ICH Q3D; outer layer: USP Class VI, 3-A Sanitary Standards 18-03 Class I, D.M. 21/03/73, FDA, BfR, European Pharmacopoeia 3.1.9, ISO 10993-4, -10, -11, non-cytotoxic (ISO 10993 Part 5). The hose complies with 1935/2004/EC, 2023/2006/EC (GMP), manufactured in Cleanroom ISO 14644-1 Class 8, free from phthalates, adipates, nitrosamines, animal-derived substances, substances subject to EC 1907/2006 (REACH). Confirmation of resistance and conditions of use requires contact with Tubes International. For confirmation of resistance and conditions of use, please contact Tubes International. Installation: use fittings with a smooth spigot (“tail” for the hose) that do not have sharp or high ribs that could cut or damage the inner PFA layer when tightened. The diameter of the spigot should be precisely matched to the diameter of the hose to ensure sealing. Installation with clamp sleeves or bands (clamps). Inner layer: transparent PFA polymer. Reinforcement: AISI 302 stainless steel spiral. Outer layer: transparent silicone. Working pressure: from 1 bar to 3 bar, depending on the hose diameter. Operating temperature: from -30°C to +150°C.
