Our USA Lab Female to Male Adapter Glass has a built in tube allowing it to flow in a straight line. This can help when pulling the liquid with a vacuum. The stopcock adapter also includes a screw in adjuster to adjust the flow rate within the stopcock.
We ship all glassware products with additional care, but sometimes they arrive broken. If glassware arrives broken, please contact us within 3 days of receiving your product and we will either send you a brand new piece or send you a refund! Any glassware broken after that voids all warranties. Thank you for understanding!

Glassware does NOT carry any warranty. Glassware items with a defect or other issue must be identified within 3 days of arrival and USA Lab MUST be contacted. After 3 days, there will be no replacements sent for glassware items with a defect or issue.
