pre-Stopperd before Irradiation
Note : Gray Hue is part-evidence of ultra-clean treatment

10ml Clear Vials ONLY. . . . uses our components
CTSC-10V-20T-22D45H

CT-20BNRB-C . . . 20mm Stopper
CT-20-OH-CrimpAl
Slab Size of 198ea - Shrink-wrapped in plastic

Supplied : Production Clean

But NOT necessarily Organic (VOC) Clean

can be syringe filled 5ml max recommended
due to part pressurisation possibilities User Beware

Disclaimer : Fillinig with fluid to 50% momentarily pressuries the vial - on withdrawing needle pressure dissipates
Overfilling ( >75% ) can leave residual pressure - on needle re- penetration spurting may occur

USE at Own Risk - Take Precautions
These vials are supplied treated washed and “gamma irradiated”
NO GUARANTEES or Warranty is offered by Chromalytic and they must be used with asceptic handling procedures
where deemed necessary

These gamma-irradiated Vials are supplied for use for R&D laboratory use ONLY by suitably trained technicians,
they are NOT Tamper Proof / evident or certified for any particular use.
Uses are adviser to use discretion and all due dilgence in applyng them for any given application

To ensure max Sterility - use sterile processes and methodology in ALL handling - Your responsibilty !
for example for final Vial filling - Use a Sterile Syringe Filter 0.22um Pore is regarded as providing a high degree of sterility
0.45um is limited in this respect
For “oils” or non polar material use

- PVDF ”SFPVDF025022SG with a 1.0um Glass Fibre pre Filter
For water solutions . . .

- Nylon SFNY025022SG

These 0.22um filter can be very slow ie easily blocked

- in which case use 0.45um version then followed by a the 0,.22um for more effective sterilisation
0.45um only achieves a partial sterilisation ( some

The 1um GF prefilter helps remove difficult suspended particulate material preserves/prolongs the life of the main filter

Choice of filter materials is left to users discretion

- PES ( polyethersulfone) a newer media is reported to produce faster and more effective filtration for many water based applications versus Nylon, cellulose acetate etc

Use of full vacuum filtration - flask / funnels vacuum Pump ( motorised ) is recommended for “bulk Solutions” and “initial” cleanup
