Aldrich® Sure/Stor™ Flask

Capacity: 25 mL, Clear Glass

Designed for safe, reliable storage and dispensing of air-sensitive and odoriferous chemicals, pyrophorics, alkyl lithiums, Grignards, corrosives, and purified or deuterated solvents.

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

*The coating is a thermoplastic film that softens appreciably at temperatures above 110 °C, becoming less protective. Tests show that the coating is 100% effective in preventing flying glass when a fully evacuated flask is broken.

Sure/Stor Technique

Connect flask to vacuum line to pump out air and strong odor, then refill with inert gas
Open PTFE valve sufficiently to allow syringe needle (or pipette) to pass through septum-inlet and reach the stored liquid in flask
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)
For long-term storage, replace hose connector with a rubber septum for secondary protection
