Take control of your results by putting an end to aliquoting
Your life is about to change for the better if you’re one of the more than 80% of researchers that aliquots their FBS into 50 mL conical tubes. Transferring your FBS removes your control over how you spend your time, the chance of contamination, and the constancy of your volume. It also wastes valuable resources.
The One Shot FBS bottle eliminates the necessity for aliquoting and the associated unpredictability. As a result, your chances of getting consistent results to grow.
“This bottle allows the convenience of speed while maintaining a sterile product. As we have lots of undergrads in and out of the lab, this ensures that one mishap with not-so-aged hands doesn’t ruin a whole pack of FBS.”
Bethany C. Prudner, PhD Metabolomic Sarcoma Lab, Washington University in St. Louis
- The picture provides the rationale behind the environmental claim that packaging of Gibco One Shot Fetal Bovine Serum (FBS) in 50 ml bottles results in the generation of 33% less plastic wastes than aliquoting from 500 ml bottles. The result is less risk of contamination and improved consistency, but also less waste to manage in the lab.
- One shot FBS 50 ml bottle eliminates the need to aliquot, which means that the FBS is frozen and thawed just once. Because the bottle is engineered specifically to withstand the freeze/thaw process, the risk of cracking lids popping off, which can happen with conical tubes, has been eliminated. The result is less risk of contamination, improved consistency, and more time to spend on your research.

Benefits of One Shot FBS
End aliquoting
By aliquoting your FBS into 50 mL conical tubes, you increase the chances of compromising your results. The One Shot FBS 50 mL bottle’s size and design eliminate that step, putting you in control of your time, contamination risk, and volume consistency.

Pour and pipet with ease
The bottle’s wide mouth and chamfered edge enable smooth, burp-free pouring. And, unlike with the current One Shot bottle, you can use a 25 and/or 50 mL pipette. Whichever way you go, you’ll get to every last drop

Stop the freeze-thaw-repeat cycle
Skipping the aliquot step means you only have to freeze and then thaw your FBS once—saving considerable time and effort. And the bottles are engineered to withstand freezing, so they won’t crack and pop their lids like conical tubes often do.

End labeling mishaps
Missing SKU or lot numbers, expiration dates, origin—or even the entire label—can cause a chain reaction of problems. The One Shot bottle has an easy-to-read package label, so you know exactly what you’re using.

Free up freezer space
The One Shot FBS package design is optimized to ease the burden on your freezer capacity.
In fact, the One Shot FBS 10 x 50 mL carton allows you to store up to 35 L more FBS in an average 20 ft. freezer than our current 40 x 50 mL One Shot carton, and 57 L more than our 100 mL bottle.

Pack the rack
Your test tube racks aren’t just for conical tubes anymore. The One Shot FBS 50 mL bottle fits perfectly in most test tube racks—including strong, durable 30mm Nalgene Unwire Racks. So you get the convenience of fitting in an easy-pour, easy-store, aliquot-free bottle.

Create less waste
The One Shot FBS 50 mL bottle generates 33% less waste than aliquoting from 500 mL bottles (see table below). By using less plastic, less petroleum feedstock is consumed, and fewer greenhouse gas emissions are generated. In the lab, a typical customer using 20 L of FBS per year would get back almost 7 hours and generate 7 lb less plastic waste by choosing One Shot FBS. This is a significant benefit both to lab productivity and the environment.
