These unique adapters greatly simplify the transfer of solids contained in round-bottom flasks into vials. Precision machined, chemically inert PTFE adapters will not seize in the joint. A wide range of thread sizes are available to accommodate most sample vials including scintillation vials (22 mm threads).

• Transfers samples without exposure to air or moisture
• Reduces sample losses due to air currents and static charge that can normally cause light solids to float or blow away when transferred open to the air
• Excellent for transferring fluffy lyophilized samples, especially peptides
• Transfers any freely flowing solid and eliminates weighing paper or other intermediate devices

Easy to Use: Screw sample vial into bottle thread at top of adapter. Insert other end of adapter into flask joint. Invert assembly and gently tap vial on a soft surface to transfer solids from flask into sample vial.

Care must be used when tapping vial to prevent accidental breakage. Tapping on a cork ring or other soft surface is recommended.
