Lab epoxy countertops, that is, laboratory epoxy countertops, are a capable assistant in laboratories. Whether it’s a chemistry lab, biology lab, or physics lab, you can see its presence.
Today, let’s talk about this countertops in detail, looking at their specific applications in laboratories and why they are favored by so many experimenters.It’s so popular because of its excellent performance in various experimental scenarios. From daily simple experiments to complex precision operations, it can steadily hold the scene.

High-frequency use in chemical experiments

In chemistry laboratories, lab epoxy countertops have the highest appearance rate, and you can see them on almost every operating platform.
Every day, various acid-base reagents and organic solvents interact on the countertop, such as concentrated hydrochloric acid, sodium hydroxide solution, alcohol, acetone, which can be spilled if you’re not careful.
Once during an acid-base neutralization experiment, a colleague was holding a beaker of concentrated sulfuric acid and turned around, accidentally tripping over a wire. The whole beaker of concentrated sulfuric acid splashed onto the countertop with a crash. Everyone was frightened at that time and quickly followed the emergency procedure: first wipe off most of it with a dry cloth, then repeatedly wipe with sodium bicarbonate solution. After cleaning, it turned out that the countertop was completely fine—no corroded pits, no yellowish-black marks, just like it had never been splashed with sulfuric acid.
You know, if it were an ordinary marble countertop, it would have been corroded beyond recognition by sulfuric acid, and might even emit a pungent smell; if it were a wooden countertop, it would probably have been burned into a big hole on the spot.
In addition to corrosion resistance, it’s also very useful when preparing reagents. Sometimes, you need to stir the solution quickly in a beaker with a glass stirring rod, which will inevitably touch the countertop.
Even if you scratch hard, no trace will be left on the countertop. Once when preparing a viscous colloidal solution, the stirring rod scraped on the countertop dozens of times. When we stopped, the countertop was still smooth. This is very important for chemical experiments. After all, no one wants to have more scratches on the countertop after each reagent preparation, which not only hides dirt but may also affect the accuracy of the next experiment.

Cleaning guarantee in biological experiments

Biological laboratories have particularly high hygiene requirements. Even a little bacterial residue may affect experimental results, and lab epoxy countertops play a great role here. Its surface is as smooth as a mirror, without any tiny gaps or pores, so bacteria and impurities have nowhere to hide. After each cell culture experiment, just wipe it back and forth twice with an alcohol cotton pad, and the bacteria on the countertop will be completely eliminated, without worrying about polluting the cells cultured next time.

Once during a mold culture experiment, a petri dish full of mold was accidentally knocked over, and green hyphae and culture medium flowed all over the countertop. At that time, we were busy handling samples and forgot to clean it for two hours. By then, the culture medium had dried hard, like a layer of glue stuck to the countertop. We thought we had to scrub hard with a brush to clean it, but we poured some warm water and soaked it for five minutes, then gently wiped it with a cloth. All the hard lumps fell off, and the countertop instantly returned to its original appearance without even a trace of color. If it were a countertop with gaps, mold spores might have already 钻进 the gaps. Even if wiped with alcohol, they couldn’t be completely killed, and new mold might grow in the gaps in a few days, which would be a big trouble.

Another time, when handling animal tissue samples, the countertop was stained with a lot of blood and tissue fluid. According to regulations, such pollutants need to be soaked in special disinfectant before cleaning. At that time, after pouring the disinfectant, we answered a phone call and forgot to wipe it off in time. When we remembered, more than an hour had passed. We thought the countertop might be stained, but it was clean with a wipe, leaving no trace. This easy-to-clean feature ensures a sterile environment in biological laboratories.

Load-bearing capacity and wear resistance in physics experiments

Load bearing

In physics laboratories, various instruments and equipment are quite heavy, and the load-bearing capacity of lab epoxy countertops is impressive.
Large instruments like spectrometers and oscilloscopes, which often weigh dozens of kilograms, can be placed steadily on the countertop. Even if they are moved around every day, the countertop will not sag or deform.
Once when the laboratory was moving, several workers were carrying a precision balance weighing several hundred jin. They didn’t stand firmly, and one corner of the balance hit the countertop heavily, making a loud “thud”.
Everyone thought the countertop must have cracked, but upon closer inspection, there was only a shallow white mark. It felt smooth when touched, and even the white mark disappeared after a few days.

Wear resistance

Lab epoxy countertops wear resistance is also reassuring.
In mechanics experiments, weights and metal brackets are often placed on the countertop, and sometimes these heavy objects need to be slid to adjust positions.
Once during a friction coefficient experiment, a metal block was dragged back and forth on the countertop hundreds of times, but the countertop still had no scratches. Another time, when cutting a metal strip with a hacksaw, the sawdust splashed onto the countertop, bouncing around. After cleaning, the countertop was checked and found to have no damage.
This wear-resistant feature allows the countertops in physics laboratories to remain intact for a long time without frequent replacement.

Practical performance in sample processing

Soil sample

Processing samples is common in laboratories, whether it’s soil, plants, ores, or industrial waste, lab epoxy countertops can handle them easily. When grinding soil samples, sometimes you use too much force, and the mortar will scrape hard on the countertop.
Even if you scrape for dozens of minutes, the countertop will not be scratched; when cutting plant specimens, using a blade to scratch back and forth on the countertop, the countertop remains as smooth as new.

Industrial part

Once when processing a batch of industrial part samples with heavy oil stains, the countertop was stained with a lot of engine oil and cutting fluid, which was black and sticky.
At that time, we first wiped off most of the oil stains with paper towels, then poured some ordinary detergent, and wiped with a cloth.
All the oil stains were gone, and the countertop instantly became clean without any greasiness. If it were an ordinary countertop, the oil stains might have seeped in long ago, and after wiping, a black mark would still remain.

Ore powder

It’s also worry-free when handling ore powder.
Once when grinding a sulfur-containing ore, the powder was very fine, sticking to the countertop like a layer of ash. We thought it would be hard to wipe off, but it was gone with a wipe of a wet cloth, leaving no residue even in the gaps.
This is very important for subsequent experiments. If sample powder remains on the countertop, it may mix in when processing other samples next time, causing cross-contamination and affecting the accuracy of experimental data.

Durability advantages in teaching experiments

Lab epoxy countertops are indispensable in teaching laboratories. Students who are new to experiments are not proficient in operations and are inevitably clumsy. Sometimes they drop beakers and test tubes on the countertop, or spill reagents everywhere. But with it, teachers can save a lot of worry. Once in a chemistry experiment class, a student accidentally knocked over a beaker heated to boiling. The scalding hot water and solution flowed all over the countertop, and some even splashed onto the edge of the countertop. The teacher quickly asked the students to step back. After the countertop cooled down, it was wiped with a cloth and turned out to be undamaged—neither deformed nor discolored. If it were a plastic countertop, it would probably be burned into a big hole on the spot and might release harmful gases.

Moreover, because it’s particularly durable, even if used by several batches of students every day, it will look like new after five or six years. The epoxy countertops in a teaching laboratory have been used for eight years. Except for slight wear on the edges, the overall appearance is still intact, which is much better than other material countertops used before. The previous marble countertop was full of scratches and pits after two years and had to be replaced entirely, which was both costly and delayed the course.

Adaptability in special experimental environments

Some laboratory environments are special, such as high-temperature and humid places, and lab epoxy countertops can easily adapt. In high-temperature laboratories, utensils just taken out of the oven are often placed on the countertop, with temperatures reaching over 100 degrees Celsius. Sometimes heating plates are even placed directly on the countertop. Even so, the countertop will not soften and deform like a plastic countertop, nor will it crack like a wooden countertop. Once a student forgot to turn off the heating plate and left it on the countertop. When found the next day, the heating plate had been on all night, and the part of the countertop in contact was a little hot, but after cooling, no trace was left.

It also performs well in humid environments. There is a microbiology laboratory that maintains a humidity of over 80% all year round to ensure the culture environment. Sometimes the walls even get moldy, but the epoxy countertops on the platform always remain dry and clean without any signs of mold. After more than five years of use, the surface is still as smooth as when it was first installed, without bulging or delamination due to humidity. If it were a wooden countertop, it would probably have rotted away; if it were a metal countertop, it would probably be covered with rust.
