A must for use in the Lab *by N***P on August 2, 2025* We use these all the times in our Horse Breeding Lab. Great product. Reliable. Highly reccomend. ### ⭐⭐⭐⭐⭐ Seem to be great! *by S***. on February 19, 2022* I'm not using these in an actual centrifuge. I bought them for pre-measuring out oxy shock powder for my hot tub. They work wonderfully for this. The lids fit tightly and stay put, graduation markings are solid and easy to read, and they're very inexpensive. This ticks all of the boxes for my needs. ## Frequently Bought Together - Membrane Solutions Conical Centrifuge Tubes 50mL, 25 Pack Sterile Plastic Test Tubes with Screw Caps, Polypropylene Container with Graduated and Write-on Spot, Non-Pyrogenic, DN/RNase Free - Transfer Pipette, 7.0ml Capacity, 3.0ml Graduated, Large Bulb, 155mm, 3.2ml Bulb Draw, Karter Scientific 206H3 (Pack of 100) - AmScope 72 pcs.
