True Costs of N2 Tanks
Nitrogen gas is a vital component in many laboratory processes, from preserving biological samples and enabling precise analytical techniques to maintaining an inert atmosphere for sensitive reactions. Traditionally, laboratories have relied on rented nitrogen gas cylinders to meet their needs. However, this method comes with various costs that can significantly impact operational budgets. As laboratories strive for efficiency and cost-effectiveness, understanding these expenses is crucial in making informed decisions about nitrogen gas supply. This article delves into the comprehensive costs associated with renting nitrogen gas cylinders and explores the advantages of transitioning to on-site nitrogen gas generation.

Breaking Down the Costs Associated with Renting Nitrogen Gas Cylinders
1. Rental Fees - One of the most straightforward costs of using nitrogen gas cylinders is the rental fee. Gas suppliers charge laboratories for the use of their cylinders, with prices varying based on cylinder size and rental duration. These recurring fees can add up quickly, especially in facilities with high nitrogen consumption.
2. Gas Refills and Delivery Charges - In addition to rental fees, laboratories incur costs for the gas itself and the delivery services. Refilling nitrogen cylinders involves purchasing the gas at market rates, which can fluctuate. Moreover, delivery charges are often applied, with some suppliers imposing extra fees for expedited or out-of-schedule deliveries. For laboratories in remote locations, delivery costs can be significantly higher.
3. Handling and Maintenance - Handling nitrogen cylinders requires careful attention to safety protocols and equipment. Some laboratories invest in specialized handling equipment, such as carts and cranes, to move heavy cylinders safely. However, on a couple of occasions, Lab Techs have noted needing to transport tanks up and down flights of stairs which is a major safety concern (please see #7 below). Even if this is done with care, accidents do happen, and generally speaking, it isn’t difficult to imagine that most researchers would rather be focusing on their science than completing manual labor! Routine maintenance of storage and handling infrastructure is necessary to ensure safety and compliance with regulations. These handling and maintenance requirements contribute to the overall operational costs.
4. Storage Space - Ideally, nitrogen cylinders require dedicated space within laboratory facilities. This space must meet safety standards and often needs to be away from high-traffic areas to minimize risks. Unfortunately, the most common setup we come across is each evaporator or gas chromatograph connected to its own tank. Sometime this isn’t so bad with tanks being placed in the back corner, but sometimes, the aisles of the laboratories become even more narrow due to bulky tanks being placed besides hoods and gas tubing becoming a potential hazard. The cost of allocating and maintaining suitable storage areas can be substantial, especially in laboratories with limited space. Moreover, some facilities may need to rent additional storage space, further increasing expenses.
5. Cylinder Management and Inventory Control - Managing a steady supply of nitrogen involves tracking cylinder inventory, ensuring timely returns, and coordinating with suppliers for refills and replacements. This task often requires dedicated personnel or administrative resources. Mismanagement or delays can lead to operational downtime and additional costs for emergency supplies.
6. Regulatory Compliance - Nitrogen gas cylinders are subject to various safety and regulatory standards. Laboratories must invest in regular safety training for staff, as well as inspections and compliance measures to adhere to local and national regulations. Non-compliance can result in fines and penalties, adding to the overall costs.
7. Environmental and Safety Risks - The transportation and storage of nitrogen cylinders pose environmental and safety risks. Potential leaks or accidents during handling and storage can lead to hazardous situations. Laboratories may face costs related to mitigating these risks, such as investing in safety equipment and insurance.
Advantages of On-Site Nitrogen Generation
Given the myriad costs associated with renting nitrogen gas cylinders, many laboratories are exploring the option of on-site nitrogen gas generation. Installing a nitrogen generator offers several compelling benefits:
1. Cost Efficiency - On-site nitrogen generators eliminate the recurring rental, refill, and delivery fees associated with gas cylinders. While the initial investment in a generator and installation may be significant, the long-term savings on operational costs make it a financially sound decision. To comment on nitrogen consumption related to Organomation evaporators, if a laboratory is replacing a nitrogen tank more than once a month, they are a prime candidate to transition to a generator and reap meaningful savings long term.

2. Continuous Supply and Reduced Downtime - With on-site nitrogen generation, laboratories can ensure a continuous and reliable supply of nitrogen, eliminating the risks of supply shortages or delays in delivery. This uninterrupted availability enhances operational efficiency and minimizes downtime.
3. Enhanced Safety and Convenience - Generating nitrogen on-site reduces the need for handling and storing high-pressure cylinders, thereby minimizing safety risks and simplifying operations. Laboratories can streamline their processes and focus on core activities without the burden of managing external gas supplies.
4. Space Optimization - By eliminating the need for bulky cylinder storage, laboratories can optimize their use of space. This advantage is particularly beneficial for facilities with limited space or those looking to expand their operational areas.
5. Environmental Benefits - On-site nitrogen generation is a greener alternative, reducing the carbon footprint associated with the transportation and handling of gas cylinders. This eco-friendly approach aligns with sustainability goals and can enhance a laboratory's reputation for environmental responsibility.
Increase Lab Efficiency Through On Site Gas Generation
As laboratories continue to seek efficiency and cost-effectiveness in their operations, transitioning from rented nitrogen gas cylinders to on-site nitrogen generation emerges as a compelling solution. The comprehensive costs of renting cylinders—from rental fees and delivery charges to handling and regulatory compliance—underscore the economic and operational burdens associated with this traditional method. In contrast, on-site nitrogen generation offers substantial long-term savings, enhanced safety, continuous supply, and environmental benefits.
For laboratories aiming to streamline their processes, reduce costs, and uphold the highest standards of safety and sustainability, investing in an on-site nitrogen generator is a forward-thinking and prudent choice. By embracing this modern approach, laboratories can not only optimize their nitrogen supply but also contribute to a more efficient and environmentally conscious operational model.
