Hey everyone, quick question that comes up a lot in our DMs: can you use a beaker tong for beakers in a cold environment? As someone who’s been supplying these things for 6 years now, I’ve answered this so many times I could probably ramble about it in my sleep. But let’s cut the small stuff—this is actually way more relevant than most people think, especially if you’re in a lab that deals with super cold stuff on the regular, right? Beaker Tong
First off, let’s get one thing straight: a cold environment here isn’t just “your lab is set to 60°F because your coworker hates heat” (don’t get me started on that). We’re talking cryogenic freezers, cold rooms where you’re running samples at -20°F or lower, maybe even field work where you’re handling beakers filled with liquid nitrogen or dry ice slurries. Those aren’t the same as a warm room, and your beaker tong needs to hold up, not slip or freeze to the beaker mid-task.
Let me start with what beaker tongs are made of, because that’s the whole crux of this question. Most standard tongs you’ll find in a basic lab supply kit are stainless steel, right? Or sometimes a coated metal for grip. Wait, but—stainless steel at super cold temps? I learned this the hard way when a new intern at a customer’s lab grabbed a beaker of dry ice water with a cheap old steel tong, and the tong’s jaws froze right to the glass. They had to chip it off with a spatula, and nicked the beaker so bad it was useless. Oops. Turns out, regular stainless steel doesn’t handle extreme cold well—wait, actually, it does, but wait no—wait, no, let’s clarify: 304 stainless (the cheap stuff) can get a little brittle below -40°F, and even worse, it conducts cold like crazy. So if it’s cold enough, the metal of the tong will pull the cold right onto the contact point, and if there’s any moisture at all (even a tiny bit from the beaker condensation), it freezes solid. That’s the big problem everyone runs into.
But here’s the thing: not all beaker tongs are created equal. We supply a ton of different options, and we’ve worked with labs that do cold storage for years, so we’ve got the stuff that actually works. Let’s break down the pros and cons of using beaker tongs in cold environments, not just the flat yes/no.
First, when you CAN use a beaker tong for cold beakers: if the environment isn’t extremely cold, like -20°F or above. A normal lab cold room, for example, if it’s just storing samples, not running super low temps, our standard coated stainless tongs work fine. The coating (usually a silicone or rubber grip) acts as a barrier, so even if there’s a little condensation, it doesn’t freeze the metal to the beaker. We’ve had customers who run PCR labs use these all the time for pulling frozen sample beakers out of freezers, and they haven’t had a single slip or freeze incident in over a year. That said, even here, you gotta be smart—don’t leave the tong sitting in the cold room for hours beforehand, because the coating will get stiff if it’s too cold, and grip gets worse. Keep the tong at room temp until you need it, that’s a simple hack.
Now, the big “but” that’s everyone asking about: extreme cold, like cryogenic temps (-150°F and lower). Here’s where regular tongs fall apart, but not because all beaker tongs are useless. Wait, no—let’s get real. If you use a standard stainless steel tong here, two things go wrong: first, the metal’s coefficient of thermal expansion changes. Glass (which most beakers are made of, right? Except some plastic for cold work) shrinks a tiny bit when it’s super cold, and if the tong is expanding or contracting at a different rate, the grip gets wonky. Second, as I mentioned before, the cold conductivity leads to freezing. A lot of labs make the mistake of grabbing a regular tong, and boom—frozen on. We had a customer who handles liquid nitrogen beakers tell us that cost them $800 in broken beakers and lost samples last year, all because their old supplier told them any tong works. Rookie mistake.
But wait—we have specialized beaker tongs for exactly this scenario. Let’s talk about what makes them different. First, the material: most of our cold-environment tongs are made of aluminum alloy with a PTFE (Teflon) coated grip. Aluminum is way less conductive than stainless steel, so it doesn’t pull that extreme cold to the contact point. The PTFE grip is non-porous, so no moisture gets trapped to freeze. Also, the jaws are shaped a little differently—more serrated, but not too sharp, so they grip the beaker without putting too much pressure on it (which is important because cold glass is more brittle, right? Drop it from a foot up, even a tiny nick turns into a million pieces). I tested one of these myself last winter when we were setting up a demo for a local university’s cryo lab—grabbed a beaker with liquid nitrogen (so like -320°F, for reference) and it didn’t stick at all. No frost on the jaws after, easy to slide right off once I set it down. That’s the stuff you need when temps are that low.
Wait, but what if someone tries to use a plastic beaker with a plastic tong? Is that okay? Let’s be real, plastic beakers are fine for a lot of cold work, but plastic tongs—most are cheap, they get brittle below freezing, and the grip just doesn’t hold. I saw a grad student try that last semester, the tong cracked mid-lift and the beaker went flying, spilled dry ice all over the floor. Fun for her, not fun for anyone else. So plastic tongs are a hard pass for any cold environment, no matter how mild.
Another thing to consider: user error, because let’s face it, most of the issues people have aren’t the tool, they’re the person holding it. I can’t tell you how many times a customer has come back saying their tong doesn’t work, and it turns out they’re grabbing the beaker too low on the base, where the glass is extra cold, and their hand is sweating so the condensation freezes. Pro tip: grab the beaker about an inch below the rim, where it’s warmer? Wait, no—wait, in cold temps, the entire beaker is cold, so maybe wipe a little dry ice frost off the spot you’re gripping before you close the tong. That takes 2 seconds, saves you a broken beaker. Also, don’t over-tighten the tong—like I said, cold glass is fragile, squeezing too hard can crack it before you even lift it. We put that in every product manual, but no one reads those, right?
Let’s also talk about maintenance, because that’s part of whether a tong works in cold environments over time. If you’re using your tong in a cold room, you have to let it warm up to room temp every now and then to get rid of any moisture that’s seeped into the hinge. If you leave it in the cold for weeks on end, the hinge can seize up. We have customers who rotate their tongs—one for regular room use, one for cold rooms, one for extreme cold—so each only gets exposed to one temp range. That’s way cheaper than replacing tongs every couple months from freeze damage. And don’t use harsh chemicals to clean them after cold work—like, if you just pulled a liquid nitrogen beaker, don’t douse the tong in hot water right away. Thermal shock will make metal brittle and can crack the grip. Let it thaw slowly at room temp, that’s the way to go.
Wait, let’s address a common myth here: some people think if you just cover the tong jaws with a towel or something, you can use any tong. Uh, no. Towels soak up moisture, so they’ll freeze solid on the beaker too. I’ve seen that, it’s a disaster. You’re better off using the specialized tongs than improvising with lab scraps. We’ve even had clients come to us after trying that, and they ended up spending more on broken beakers than they would’ve on the right tongs. That’s a hard no from me, don’t improvise here.
Let’s wrap this up with a clear, no B.S. answer, because I know you just wanted a straight up take: Yes, beaker tongs can be used for beakers in cold environments—BUT only if you pick the right tong for the temperature, and follow a few basic rules. For mild cold (like standard lab cold rooms, -20°F and above), our standard silicone-coated stainless steel tongs work great, just make sure you don’t leave them sitting in the cold. For extreme cold (cryo work, liquid nitrogen, -150°F and lower), you need our specialized aluminum alloy PTFE-coated tongs—they’re designed not to conduct cold, no freezing to the beaker, and grip without cracking glass. And never, ever use plastic tongs or try to improvise with towels, that’s how you end up with a mess.
