How to Use the Chemical Compatibility Chart Vials and Closures

G – Good chemical resistance, Some background extractable possible, suitable for general analysis F – Fair chemical resistance, signifi cant background extractables possible, for short term use SE – Surface effects possible after short exposure, always evaluate suitability before use. C – Conditions of exposure can affect compatibility

Chemical resistance: Excellent until punctured Maximum temperature: 90°C Suitable for: Temporary storage only Polyethylene Advantages: Low cost Chemical resistance: Good; not resealable Maximum temperature: 175°C Suitable for: Single injections only Polypropylene Advantages: Low cost Chemical resistance: Good; not resealable

Comparative Leachable Study of Glass Vials to Demonstrate the

The pharmacopeia method for measuring the chemical durability of parenteral glass packaging is the hydrolytic resistance test in which the vial is filled to 90% of its brimful volume as described, for example, in USP <660>. However, an increasing number of innovative drugs are filled significantly below the nominal volume of the vial. As a consequence, the determined hydrolytic resistance is

The extractables profiles for size-matched vials are presented in Figure 3 and include only extracted elements with a reported concentration greater than 0.01 ppm (µg/ mL). A comparison of the total amount of extractables for each vial type is presented in Figure 4.

Headspace sampling fundamentals, what is headspace | Aijiren

Headspace vials often come in larger volumes than the 2-mL vials used in many liquid sampling systems. Common offerings are 10-mL, 20-mL and 22-mL capacities. Larger vials accommodate larger sample volume and/or a larger headspace above that sample.
