Serological pipettes are essential laboratory tools used for accurate liquid transfer. They consist of a long, graduated glass tube with a narrow tip and a rubber bulb attached to its top. The bulb provides suction and expels air to control the flow of liquid through the pipette. Additionally, serological pipettes often have a cotton plug or filter tip attached to the tip to prevent contamination and ensure precision dispensing. These components, including the rubber bulb, cotton plug, and filter tip, play crucial roles in the functionality and accuracy of serological pipettes.
Pipette Tips: The MVPs of Liquid Handling
Pipette tips, those humble little plastic attachments, are the unsung heroes of every laboratory. They’re like the socks to your favorite sneakers – essential, but often overlooked. So, let’s give these tiny marvels the spotlight they deserve!

Reverse Pipette Controllers: Break the mold with reverse controllers! These nifty devices aspirate by pushing air out, making them ideal for pipetting viscous liquids or samples that tend to foam.
Choosing the Right Pipette Controller:
Selecting the perfect pipette controller is like finding your soulmate – it depends on your specific needs and preferences. Consider:
- Frequency of use: If you’ll be pipetting all day long, an electronic controller will save your hands from cramps.
- Accuracy and precision: For critical applications, electronic or reverse controllers offer the highest levels of accuracy.
- Multi-sample handling: If you’re dealing with multiple samples, a multichannel controller will streamline your workflow.
- Budget: Controllers come in a range of prices, so set a budget and explore options within your means.
Remember, your pipette controller is a trusty companion in the laboratory. Treat it with care, keep it calibrated, and it’ll serve you faithfully for years to come. Embrace the symphony of pipetting and let your pipette controller guide you to scientific success!
The Pipette Stand: Your Pipette’s Safe Haven
In the pipette world, precision is everything, and contamination is public enemy number one. That’s where the humble pipette stand comes in – your trusty sidekick in the battle against pipette peril.
The Magicians of Pipette Stands
Pipette stands come in all shapes and sizes, from the basic carousel design to the high-tech wonders that look like they belong in a space lab. But no matter the bells and whistles, they all share one crucial purpose: protecting your pipettes.
Why a Pipette Stand is Your Pipette’s Knight in Shining Armor
-
Prevents contamination: When pipettes are left lying around, they become a breeding ground for unwanted guests like bacteria and dust. A pipette stand keeps your pipettes upright and out of harm’s way, minimizing the risk of contamination.
-
Prevents damage: Pipettes are delicate instruments, and a clumsy fall can ruin their calibration or even break them. A pipette stand provides a stable base, keeping your pipettes safe and sound.
How to Choose the Perfect Pipette Stand
Choosing the right pipette stand is like finding a stylish yet functional sidekick. Here’s how to do it:
- How many pipettes do you need to store? From solo acts to pipette armies, choose a stand that can accommodate your needs.
- Do you need any special features? Some stands have built-in racks for tips or lights for easy visibility. Decide what you can’t live without.
- Autoclavability: If you’re dealing with germ warfare, opt for a stand that can be sterilized in an autoclave.
Storing Your Pipettes Like a Pro
Once you’ve got your pipette sanctuary, follow these golden rules for storing pipettes:
- Always place pipettes vertically: This keeps liquid from flowing into the shaft, preventing contamination and damage.
- Keep pipettes dry: Wipe off any droplets before storing them.
- Avoid overtightening: Excessive force can damage pipettes.
With these tips and the right pipette stand, your pipettes will be happy and healthy, ready to conquer the world of precision pipetting, one drop at a time.
Pipette Washer: An Automated Elixir for Pipetting Woes
Pipette washing: the bane of every lab technician’s existence. But fear not, my weary pipetters, for the pipette washer has arrived to save the day!
Types of Pipette Washers
Pipette washers come in two main varieties: manual and automated. Manual washers require a bit of elbow grease, but they’re still better than hand-washing, trust me. Automated washers, on the other hand, are a godsend, effortlessly cleaning your pipettes with the power of technology.
Benefits of Automated Pipette Washers
- Time-saving: No more scrubbing and rinsing by hand. Your pipette washer will take care of all the dirty work, freeing up your precious time for more important things, like coffee breaks.

Pipette Calibrator
Pipette Calibrators: The Unsung Heroes of Accurate and Precise Pipetting
Pipettes are like the magicians of the laboratory world, effortlessly transferring precise volumes of liquids with a flick of the wrist. But, just like all magic, even pipettes need a little bit of maintenance to keep them working at their best. And that’s where pipette calibrators come in, the unsung heroes of accurate and precise pipetting.
Why are pipette calibrators so important? Well, over time, pipettes can develop slight inaccuracies, and that can have a big impact on your experimental results. A pipette that’s off by just a few microliters can lead to false conclusions, wasted reagents, and a whole lot of frustration. That’s where pipette calibrators come in. They’re like the referees of the pipette world, making sure your pipettes are performing exactly as they should.
There are a few different types of pipette calibrators available, each with its own strengths and weaknesses. But no matter which type you choose, the process of calibrating a pipette is pretty straightforward. It usually involves measuring the weight of water that the pipette dispenses and comparing it to the expected weight. If the difference is too large, you’ll need to adjust the pipette’s calibration.
Calibrating pipettes is a critical step to ensure the accuracy and precision of your experiments. But don’t worry, it doesn’t have to be a chore. Follow these three steps, and you’ll be calibrating like a pro in no time:
- Gather your tools: You’ll need a pipette calibrator, a balance, and distilled water.
- Measure the water: Calibrate your balance and dispense a specific volume of water into a weighing vessel.
- Adjust the pipette: Compare the measured weight to the expected weight. If there’s a difference, adjust the pipette’s calibration accordingly.
And just like that, your pipettes will be back in tip-top shape, ready to conquer the laboratory world once again. So, the next time you’re about to start an experiment, take a few minutes to calibrate your pipettes. It’s a small step that can make a big difference in the quality of your results.
