Key Questions to Ask When Ordering nitric acid storage container

Author: Subject: Storing con. HNO3 and other jewels Storing con. HNO3 and other jewels


I'm new to this. And I am finally living the dream and putting together a home chem lab. I have some concentrated HNO3 and HCL on order and I am worried about storage. Can they be stored together? Do I need a acid storage cabinet with the fancy blue paint?? Because, I don't have $500+ to spend on a cabinet. Any advice / strict orders would be appreciated!!!





Keep all acids away from any metals. I left a fairly large Nd magnet in a fume hood seething with HCl and it turned into a pile of rust.

Nitric and hydrochloric acids form the toxic nitrosyl chloride in aqueous solution. I don't know about gas phase, but I advise storing them apart for safety's sake. Neither should be too much of a problem for regular cabinets.

My school stores nitric acid in locked metal cabinets.

If you are worried about the fumes, just place each bottle inside a larger plastic container (Rubbermaid pitcher or other storage container) and you can even put some NaHCO3 inside the plastic container to absorb any fumes. I have done that before for acids.

Brain&Force, Yes HCl(aq) reacts with Nd magnets to isolate boron.

By far, this is THE best solution (no pun intended) for storing of acids that I have seen (excluding professional cabinets, of course) - bucket with bottom covered in some adsorbing material:

...and then I disappeared in the mist...

Or you can buy a polymer cabinet from Home Depot like stores (please boycott Wal-mart) as long as you have a ventilated area for it.

I have found wine and beer kegs that are made of glass a good storage option for short to medium for nitric acid. These bottles look a little like massive boiling flasks, and they can be stoppered with silicone or rubber plugs. I used tight rubber plugs which I lined with PTFE. This prevents air from getting in, but when the acid decomposes slightly, the pressure is allowed to leave without bursting the bottle. These kegs range from few liters to even up to 50, or even 100 liters and are usually supplied with a protective, plastic basket that allows easy handling.

Stainless steel, like 316, when clean(washed with nitric and hydrofluoric acid), will hold well against RFNA and WFNA. You will need pressure compensation though for any nitric acid over 80%, or it may explode the container.

Chemicals can be stored well without any fume hoods. The safest option is to make any box or cabinet where you have line attached to rooftop. This creates a small suction, and if any noxious fumes are evolved, they cannot exit the cabined because the very small vacuum difference formed and they are safely vented out. For other storage, take them off rooms where you live, like warehouse. Normal chemicals wont cause fumes when handled correctly, like HCl and nitric acid. Only very toxic stuff like cyanides or toxins should be handled with special care.

Wow! Thanks everyone!! That was such a big help! I might go with a combination of advice from everyone. Lots of good ideas here. Good to know I don't have to spend $800 for a fancy cabinet. Cheers!

Buckyballz: Did you happen to send me a message on YouTube about this? If not, your question is eerily similar to one I just got a few days ago. If it was you, check your inbox!

"Lined with PTFE.." How are you doing that?

chemrox , I tend to line my rubber stoppers with PTFE tape when containing chemicals that react with rubber. Eg. Chlorine, nitric acid, iodine vapour ect.
Simply wind "plumbers Tape" around your stoppers. Several layers are easily enough.

I can obtain PTFE sheets per square meter from 50 to 200mic thick. I cut round pieces from these so they will fit against lips of bottles and when I screw the top in, it will compress a tight seal so only glass and PTFE are explosed on chemicals. Tape would work too, though the top seal has seams and will not be proof. If you just wind plumber tape around threads, the chemical will still attack the bottle top and this does not proofen the top by any means, and if it leaky by nature, one should discard it instantly because taping wont fix it.

Thanks a lot!

All of my chemical safety protocol and storage is backed up by Flinn Scientific in Illinois. They advocate storing chemicals like this, and they also suggest storing HNO3 away from ALL other materials unless an acid cabinet is equipped with an HNO3 compartment (most aren't). If you look at the picture of my chemical storage cabinet, all the way to the right in the very back you can see a translucent container with a blue lid. In here, there is HNO3 in a poly-coated glass bottle in a plastic bag, with kitty litter in the bottom. Not to brag, but I am a bit of a self-proclaimed expert when it comes to chemical storage. I would be happy to post all of my patterns in the prepublication section if you are interested.

Oh, and by the way, the bucket is actually fitted with a screw top adapter I got at Lowes for less then $10. It makes for easy airtight opening/closing

As long as you aren't moving to Texas, and you have available space, starting a lab shouldn't be a problem.

It's relatively easy to make concentrated nitric acid from a nitrate salt and sulfuric acid (there are a plethora of threads on this). Dudadiesel also sells it, although it is expensive to buy due to shipping costs.

I've got my HNO3 in a glass stoppered conical flask that sits in a small plastic bucket on an open shelf and it's been like that for years. No effects on nearby items.

I am not going to Texas. Thanks for the link on that company, however they have only 70% Nitric acid, I dont think I'll find around 95% in US so it looks like I have to distill for high purity.

I don't think that anyone other than a professional chemical supplier would sell >70% HNO3. Unless you have a business and can order from Sigma Aldrich, you would have to make it.

Really? Why does everybody think Texas is a waist-land and a hard place to start a lab?
I did it, nitric acid of any concentration is easy to obtain, as are all the chemicals I have ever needed, except for those used to produce illicit narcotics.

I read somewhere that Erlenmeyer flasks are not legal for private citizens to own in Texas. Not sure what else would be outlawed, but if the legislators in Texas are going to do that then nothing would surprise me. They might as well outlaw mason jars too.

Pretty much all glassware is illegal in Texas.. Here is there definition and list of illegal things:

(B) a distilling apparatus
(C) a vacuum drier
(D) a three-neck or distilling flask
(E) a tableting machine
(F) an encapsulating machine
(G) a filter, Buchner, or separatory funnel
(H) an Erlenmeyer, two-neck, or single-neck flask
(I) a round-bottom, Florence, thermometer, or filtering flask
(J) a Soxhlet extractor

Texas is just an all around awful place - if you want to watch an incredibly frustrating documentary on netflix.. "The Revisionaries" is about the Texas school boards and how they decide what shows up in public school curriculum. They flat out undermine science and imply creationism at every turn. For example: "Evolution is xxxx, but there are some scientists who disagree with that theory".. It is extremely aggravating to watch, but it is a well done documentary.

What Is an Acid & Corrosive Storage Cabinet?

An acid and corrosive storage cabinet is designed to safely store acids and other corrosive materials. Instead of storing potentially dangerous chemicals on a simple shelf, acid safety cabinets allow you to store acids and corrosive materials in a container that is designed to prevent fires, leaks, and exposure to harmful fumes.

What Are Acids and Corrosive Materials?

Acids are chemicals that can donate protons or accept electrons to form bonds. The pH scale measures the acidity of water on a scale of zero to 14, with anything less than seven being acidic. Common acids used in laboratory settings include:

1. Chloric acid
2. Perchloric acid
3. Nitric acid
4. Sulfuric acid

Corrosive materials attack, damage, or destroy other substances, particularly living or organic tissue, through a chemical reaction. Many acids are corrosive, and some corrosive materials are acidic. However, not all corrosive materials are acids, and not all acids are corrosive. Common corrosive materials used in laboratory settings include:

1. Bromine
2. Hydrogen peroxide
3. Sodium hydroxide
4. Ammonia

Acid Storage Requirements

It’s important to note that the requirements for how to handle and store acids and corrosive materials are specific to the acid or corrosive material in question. The Centers for Disease Control and Prevention (CDC) offers guidelines for a variety of chemicals used in occupational capacities. These guidelines offer information on health risks, exposure limits, and safety recommendations.

How Does an Acid Cabinet Work?

Acid cabinets are lined with polyethylene, a material that is resistant to acids and corrosive materials. This means that if a corrosive chemical is spilled within an acid cabinet or a chemical releases corrosive gases, it won’t damage the cabinet itself.

Acid Cabinet Ventilation

Because acids and other corrosive materials may produce dangerous or harmful gases, acid safety cabinets must also be properly ventilated. 

Most acid storage cabinets are placed directly under a fume hood to allow for ventilation of harmful fumes. PVC venting kits allow you to use PVC pipe to vent fumes from acid safety cabinets into a fume hood. Acid safety cabinets also have a removable back panel that can be used for venting.

Without a fume hood, harmful gases can corrode your acid cabinet and its hardware. In a worst case scenario, acid and corrosive storage cabinets can vent toxic fumes directly into your laboratory, creating a safety hazard. Make sure your acid cabinet is properly installed with proper ventilation for your intended use.

Frequently Asked Questions (FAQs)

Can Acids and Bases Be Stored in the Same Cabinet?

An important part of safe laboratory storage is preventing accidental chemical reactions. Whether or not you can store certain acids and bases together depends on the specific properties of those chemicals and how they may react to one another when in close proximity. When in doubt, only put acids and other corrosive materials in acid and corrosive cabinets, not bases.

Acid Cabinet vs. Flammable Cabinet: What’s the Difference?

Flammable cabinets can be placed under fume hoods for ease of use, but acid cabinets must be placed under fume hoods for ventilation purposes. Flammable cabinets need to be able to close and seal to prevent feeding a fire or spreading flames, while acid cabinets need to maintain proper ventilation in order to prevent corrosive fumes from damaging the cabinet or leaking into the laboratory itself. 

Chemical Storage Cabinet vs. Acid Cabinet: What’s the Difference?

Acid safety cabinets are actually just one specific type of chemical storage cabinet. They are specially designed to address and minimize the risks of storing acids and corrosive materials. Other types of chemical storage cabinets may require different characteristics than acid safety cabinets to store their chemicals safely, such as:
