The extended 12-inch stem reaches into 1-liter reagent bottles, large culture vessels, and deep collection containers that even 9-inch pipettes cannot reach. Available in bulk, sterile individually wrapped, and sterile 20-pack formats. Order at below retail pricing from LabSupplies.com, an authorized Globe Scientific dealer.

Frequently Asked Questions
How long is the 139050 extra long transfer pipette?
The 139050 measures 300mm (12 inches), the longest disposable transfer pipette available from Globe Scientific. This length can reach the bottom of most standard laboratory bottles and carboys.
What is the difference between the 9-inch and 12-inch extra long pipettes?
The 139030 (9 inch, 6mL) is suited for standard tall bottles and flasks. The 139050 (12 inch, 23mL) reaches deeper vessels like carboys, large reagent bottles, and industrial containers, and holds nearly four times the volume per draw.
Are sterile 12-inch pipettes available individually wrapped?
Yes. The 139050-S01 provides individually wrapped sterile pipettes (100 per case) for maximum aseptic assurance. The 139050-S20 provides sterile packs of 20 (100 per case) at a lower per-unit cost.
Can I use 12-inch extra long pipettes for sampling from carboys?
Yes. The 300mm length is specifically designed to reach into standard 10-20 liter carboys and other deep containers commonly used in media preparation, buffer storage, and industrial applications.
