General description
Features:
- High-vacuum PTFE valve-to-glass seal eliminates air contamination in storage and septum leakage after initial needle penetration
- Heavy-wall borosilicate glass
- Removable side-arm hose connector for easy attachment of vacuum and inert gas lines. For long term storage, replace hose connector with a rubber septum for secondary protection. Flasks supplied with 2 septa. Order replacement septa, Z106496
- Plastic-coated* flasks reduce chance of breakage and contain spills
Sure/Stor Technique
1. Connect flask to vacuum line to pump out air and strong odor, then refill with inert gas
2. Open PTFE valve sufficiently to allow syringe needle (or pipette) to pass through septum-inlet and reach the stored liquid in flask
3. Close the PTFE valve after needle removal and pump out again to remove air and odor (use rubber septa Z553913 or Z554030 on septum-inlet)
4. For long-term storage, replace hose connector with a rubber septum for secondary protection
NOTICE: We supply high quality PTFE valves on Aldrich brand glassware that has been tested and approved by our Glass Center.
