CT50B-L

The CT50B-L is a 50 mL conical centrifuge tube in bulk pack format — built for labs that process large sample volumes at high throughput and prioritize cost efficiency over pre-organized packaging. The 15,000×g rating is notably higher than the 3,500×g standard common in many 50 mL tube formats, making the CT50B-L suitable for demanding high-speed protocols such as bacterial cell harvest, dense-pellet separations, and gradient centrifugation steps that would exceed the capability of standard 50 mL conical tubes.

Recommended

◆ 15,000×g centrifuge rating — significantly exceeds the 3,500×g limit of standard 50 mL conicals; enables high-speed bacterial harvest, dense-pellet separations, and gradient protocols in a 50 mL format

◆ Conical bottom — complete pellet recovery and full liquid aspiration without residual volume pooling at the base

◆ Bulk pack economy — 25 pcs/bag, 20 bags/case; optimized for high-volume consumption labs where per-tube cost drives format selection

◆ Bold black graduations + large white writing area — precise volume reading and direct sample labeling on the tube body

◆ Storage to −80°C — leak-proof screw cap maintains seal integrity through freeze-thaw cycles and cryogenic storage conditions

◆ DNase/RNase-free, endotoxin-free, sterile — shelf life 5 years

Ideal for: bacterial cell harvest at high RCF, large-volume gradient centrifugation, high-throughput sample preparation, any 50 mL protocol requiring centrifuge speeds beyond standard conical tube limits
