There were no initial issues, and the system seemed to integrate seamlessly into our existing setup.

Extended Use & Reliability

After several weeks of continuous use, the Harris Calorific High-Purity Single-Stage Gas Regulators, Brass 3001145 has proven to be a reliable workhorse. The regulator has maintained its performance, with no noticeable degradation in pressure stability or flow control. The brass body has shown no signs of corrosion or wear, even with constant exposure to ambient lab conditions.

Maintenance has been minimal, primarily consisting of occasional wiping down of the exterior and periodic checks of the fittings for leaks. Compared to our previous regulator, the Harris Calorific unit has been a significant upgrade in terms of reliability and ease of use. It has definitely outperformed the previous equipment, which required frequent adjustments and repairs.

Breaking Down the Features of Harris Calorific High-Purity Single-Stage Gas Regulators, Brass 3001145

Specifications

• Gas: Argon/Nitrogen/Helium compatibility ensures versatility in various laboratory applications. This allows for single regulator usage across multiple experiments.
• Inlet CGA: A 580 inlet connection allows for easy connection to standard gas cylinders. This common standard simplifies integration with existing gas supplies.
• Flow Capacity: 1020/1220/3200 Standard CFH flow capacity enables the regulator to support a wide range of applications requiring different gas flow rates. These flow rates are crucial for high-demand processes.
• Delivery Pressure: The adjustable delivery pressure range of 1-50 psig provides precise control over gas output. This precision is essential for sensitive experiments.
• Maximum Inlet Pressure: A maximum inlet pressure of 3000 psig provides a safety margin when connecting to high-pressure gas cylinders. The high-pressure rating adds an additional layer of safety.
• Diaphragm: The Type 316L Stainless Steel diaphragm, with a 4.3 cm diameter, minimizes contamination and maintains gas purity. This material choice is critical for high-purity applications.
• Dual Scale Gauges: 5 cm (2″) psi/bar dual scale gauges offer clear and accurate pressure readings in both units. This provides easy monitoring of gas pressure.
• Outlet: A diaphragm valve with a 0.6 cm (¹/₄“) tube fitting ensures a secure and leak-free connection. The fitting size is standard, facilitating easy integration with existing equipment.
• Body Ports: 0.6 cm (¹/₄“) NPT body ports allow for easy connection of additional components. The standardized port size increases flexibility.
• Leak Rate: 1 x 10^-9 cc/sec inboard helium leak rate ensures minimal gas loss and maintains gas purity. This extremely low leak rate is a hallmark of high-purity regulators.

Performance & Functionality

The Harris Calorific High-Purity Single-Stage Gas Regulators, Brass 3001145 performs its job exceptionally well, providing stable and precise gas delivery. Its accuracy and reliability are critical for our lab’s analytical instruments. The regulator’s design ensures that the gas flow remains consistent, even when the cylinder pressure decreases.

While the regulator excels in most areas, the single-stage design means that some pressure droop can occur as the cylinder empties. A two-stage regulator would offer even greater pressure stability but at a higher cost. Overall, the regulator meets and often exceeds our expectations for performance and functionality.

Design & Ergonomics

The regulator’s brass body is robust and feels well-made, instilling confidence in its longevity. The weight is substantial but not excessive, contributing to its stable operation. The gauges are easy to read and well-positioned.
