Sure/Stor Flasks
 |
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, Z10,649-6.
- Plastic-coated* flasks reduce chance of breakage and contain spills
- Amber flasks protect light-sensitive products
|
* 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 Z10,072-2 or Z12,435-4 on septum-inlet)
- For long-term storage, replace hose connector with a rubber septum for secondary protection

CHEM-FLEX transfer lines
 |
These ready-to-use transfer lines incorporate CHEM-FLEX 106 tubing which has a chemically-inert, thin-wall PTFE inner tube sheathed in clear PVC for extra strong, flexible lines that are resistant to crushing or kinking. Two 12 gauge SS needles (6 and 18in.) are connected to the CHEM-FLEX 106 tubing with nylon clamps. Liquids contact only PTFE and SS during transfers.
Note: For extra security when using large bore transfer needles, fasten septum to bottle or flask opening with a wrap-it tie.
