“This bottle allows for 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
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 eliminates 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 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 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 30 mm Nalgene Unwire Racks. So you get the convenience of fit 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 (Table 1). 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.
Table 1. Comparison of plastic waste generated by aliquoting FBS vs. using One Shot FBS 50 mL bottles. The old method of preparing aliquots from a 500 mL bottle of FBS generates 238.5 g of plastic waste, compared to only 159.0 g using One Shot FBS 50 mL bottles. Using the One Shot bottles results in a 33% reduction in total plastic waste.
