Making Lab Work Easier for Everyone
Doing research often means spending a lot of time moving liquids, mixing solutions, and keeping track of tiny samples. Whether you are a student just starting out or a professional researcher, the quality of your tools matters. At Ptidex.com, we believe that the best lab equipment is the kind that works perfectly every time so you can focus on your science.
In peptide research, things can get tricky. You often work with chemicals that can be hard on standard plastic. You also have to deal with freezing temperatures when storing your samples. That is why we have picked a specific set of tools that are famous for being durable and easy to use.
The Importance of Good Mixing
Getting your samples to dissolve or mix properly is one of the most important steps in any lab. If your solution isn’t uniform, your results won’t be consistent. Our range of mixers—from the high-speed Vortex Mixer to the gentle Tube Rotator—gives you total control over how your samples are prepared.
A Note for All Researchers
We have designed this page to be a simple guide to the most essential tools you need in your lab. We focus on tools that are easy to handle, easy to clean, and built to last. By using the right containers and mixers, you reduce the risk of accidents and make your daily lab routine much smoother.
Reliable Sample Containers
The right container keeps your sample safe from spills, contamination, and evaporation. Here are the most common tubes and vials we provide.
Microcentrifuge Tubes
These are the most common tubes you’ll see in any lab. They are small plastic tubes with a snap-cap that stays closed even when you spin them at high speeds.
- Sizes: 1.5 mL and 2.0 mL
- Use: Perfect for small drops of liquid or powder.
- Toughness: Can handle very fast spinning in a centrifuge.
Falcon Tubes
When you have more liquid than a tiny tube can hold, you use these larger “conical” tubes. They have a screw-on cap that ensures they won’t leak in your bag or on your desk.
- Sizes: 15 mL and 50 mL
- Use: Storing large batches of liquid or mixing chemicals.
- Design: Pointy bottom makes it easy to collect every last drop.
Glass & Specialty Vials
Premium glass vials for high-purity storage.
Glass Storage Vials
Strong glass containers for long-term safety. Better than plastic for avoiding chemical reactions.
HPLC & Cryovials
Includes vials for testing machines and super-tough tubes for deep-freeze storage.
Mixing & Preparation Equipment
Getting your samples mixed correctly is the secret to good research. These simple machines take the hard work out of prep time.
Vortex Mixer
The “speed mixer.” You just push your tube onto the rubber top, and it shakes it incredibly fast. It’s the best way to quickly mix a small sample in a few seconds.
Mini Centrifuge
A small, desktop-sized spinner. It spins your tubes to force all the liquid to the bottom. Great for “quick spins” before you open a tube so nothing splashes out.
Tube Rotator
This machine flips your tubes over and over very slowly. It’s perfect for samples that need to mix gently for a long time without being damaged by fast shaking.
Preparation Power Tools
A Magnetic Stirrer & Stir Bars
A plate that uses a magnet to spin a tiny “stir bar” inside your jar. It’s like a magic spoon that mixes your liquid perfectly without you having to touch it.
B Sonicator Bath
This machine uses sound waves to create tiny vibrations in water. It’s the best way to dissolve stubborn powders into your liquid without needing high heat.
“Using the sonicator bath for just 5 minutes helped us dissolve our samples much better than manual stirring ever could. Highly recommend for any new lab setup.”

Expert Tips: How to Use Your Lab Tools Properly
1. Don’t Overfill Your Tubes
One of the most common mistakes in the lab is filling a 1.5 mL tube right to the top. When you go to mix it on a Vortex Mixer, there is no room for the liquid to move, and it won’t mix well. Always leave a little bit of air at the top to allow for a good “swirl.”
2. Balancing Your Centrifuge
If you are using a Mini Centrifuge, you must always “balance” it. This means if you put a tube on one side, you must put an identical tube (with the same amount of liquid) on the exact opposite side. If you don’t, the machine will vibrate, shake, and could even break!
3. Caring for Stir Bars
Your Magnetic Stir Bars are tough, but they can get scratched. Scratches can hold onto old chemicals and contaminate your new samples. Always wash them with gentle soap and check them for damage before use. If you see a crack or a deep scratch, it’s time to get a new one.
4. Why Cryovials Are Different
Never use a standard microcentrifuge tube in liquid nitrogen. Standard plastic can become “brittle” (like dry pasta) when it gets that cold and it might shatter. Cryovials are made from a special kind of plastic that stays flexible and strong even in the deep freeze.
The History of Lab Supplies
Before plastic was common, almost everything in a lab was made of glass. While glass is great because it doesn’t react with most chemicals, it’s also heavy and breaks easily. Modern lab supplies are a mix of both. We use disposable plastic tubes (like Falcon tubes) for most daily work to avoid cross-contamination, but we still use high-quality glass for long-term storage and advanced testing (like HPLC vials).
At Ptidex, we work closely with the people who make these tools to ensure they meet the highest standards. We want you to feel confident that your supplies will never be the reason your experiment fails.
