Chemglass Sampling Tube 90 Degree 3/8 in. Hose Barb M12 for Bioreactor

Chemglass 90-Degree Sampling Tube, 3/8-Inch Hose Barb, M12 Threaded Connection for Bioreactor Vessels (CLS-1380-73)

The Chemglass 90-Degree Sampling Tube (CLS-1380-73) is a precision-engineered bioprocessing component designed for clean sterile fluid sampling and harvest line connections in glass and stainless steel bioreactor vessels. Featuring a 90-degree bent tube architecture terminated with a 3/8-inch outer diameter hose barb, this sampling assembly directs tubing connections downward or laterally along the vessel wall, minimizing mechanical stress and preventing tubing kinks in crowded headplate layouts. Constructed from high-purity, passivated 316L stainless steel with a high-grade surface finish, the assembly is resistant to aggressive cleaning agents, repeated autoclave cycles, and steam-in-place (SIP) sterilization. Equipped with a standard M12 threaded port adapter and an integrated elastomer O-ring seal, the CLS-1380-73 provides a leak-tight, sanitary seal in standard headplate sampling ports across benchtop research and pilot-scale fermentation systems.

Technical Performance & Structural Attributes

• 316L Stainless Steel Construction: High-purity metallic composition offers superior corrosion resistance, low leachables, and long-term durability under harsh bioprocess conditions.
• 90-Degree Bent Tube Architecture: Optimizes headplate space management by routing flexible tubing horizontally or vertically downward, preventing tube kinking and flow restriction.
• 3/8-Inch Hose Barb Interface: Machined barb profile ensures a secure, high-retention seal with standard 3/8-inch inner diameter flexible bioprocess tubing (such as silicone, TPE, or C-Flex).
• M12 Threaded Headplate Interface: Standardized M12 mounting thread allows direct, precise installation into compatible bioreactor headplate sampling and dip-tube ports.
• Autoclavable & Sanitary Finish: High-polish internal and external surface finish prevents cellular adhesion, simplifies cleaning protocols, and withstands repeated thermal sterilization.

Key Benefits & Applications

• Aseptic Bioreactor Sampling: Facilitates accurate mid-run liquid sampling, nutrient additions, or cell density harvests without introducing contamination to the culture.
• Headplate Cable & Tubing Management: Compact 90-degree orientation frees up valuable overhead clearance above the headplate, reducing clutter around probes and impellers.
• Upstream Fermentation & Cell Culture: Ideal for process development, biopharmaceutical manufacturing, and academic research bioprocessing in microbial or mammalian cell lines.
