Peter Huber Micro Hose Connector NW3.2 for M16x1

The Peter Huber 6090 is a precision-engineered micro hose connector designed for specialized low-volume thermoregulation tasks. This adapter features a standard M16x1 female thread that transitions to a 3.2mm (NW3.2) hose barb, enabling the connection of ultra-thin tubing to Huber's laboratory circulators. It is an essential component for applications requiring minimal fluid displacement and high precision, such as cooling micro-reactors, capillary systems, or small-scale laboratory instruments where standard 8mm or 12mm hoses are too large and cumbersome.

Key Features:

• Brand: Peter Huber
• Connection Type: M16x1 Female to 3.2mm (NW3.2) Hose Barb
• Bore Size: NW3.2 (Internal diameter optimized for micro-fluidic applications)
• Material: High-grade, chemical-resistant metal for long-term reliability
• Compatibility: Standard fit for Huber Ministat, KISS, and smaller CC series units
• Application: Ideal for micro-reactors, analytical instrumentation, and capillary cooling
• Design: Tapered barb profile for a secure, leak-proof grip with flexible micro-tubing

The 6090 micro connector is specifically designed to maintain high pressure-integrity while transitioning to small-diameter tubing. This ensures that even in complex analytical setups, the thermal fluid delivery remains consistent. Its robust construction allows it to handle the frequent temperature shifts typical of precise scientific research without compromising the seal or flow quality.

Frequently Asked Questions

1. Why use an NW3.2 connector instead of standard lab tubing?
Micro-reactors and certain analytical sensors have very small internal volumes. Using a 3.2mm hose reduces the "dead volume" in the system, leading to faster response times and less wasted thermal fluid compared to using standard 8mm or 12mm hoses.

2. What type of tubing is compatible with this connector?
This connector is designed for flexible tubing with an internal diameter (ID) of approximately 3mm to 3.2mm. Common materials include Viton, silicone, or specialized PTFE micro-hoses, depending on your operating temperature.

3. Do I need a hose clamp for this micro barb?
For low-pressure applications, the tapered barb may hold sufficiently; however, for pressurized circulation loops or high-temperature work, we strongly recommend using a small-diameter hose clamp or cable tie to prevent accidental disconnection.

4. Will this fit my Unistat?
Most Unistat models use larger M24 or M30 connections. To use this NW3.2 micro connector with a larger unit, you would first need an M24-to-M16 or M30-to-M16 reducer adapter.

5. Can this be used with silicone-based thermal oils?
Yes, the metallic construction is compatible with all standard Huber thermal fluids, including silicone oils, water-glycol mixtures, and Ethanol.
