Each glass V-Vial purchased will also include its own applicator made from borosilicate glass. This enables easy application, and proper cleaning of the glass will greatly reduce the potential for oil contamination which can be introduced into bottles over time by repeated reinsertion of typically rough-surfaced plastic applicators after each "swipe".
As an added benefit, V-vials, also known as high-recovery vials, will also allow the retrieval of nearly 100% of the oils out of the vials in undiluted and unaltered form. This is unlike the "standard" oddly-shaped bottles with shoulders or those with flat bottoms, which precludes removal of those last precious drops without heating and/or dilution.
Our glass V-vials are unused and fabricated from heavy lab grade non-leachable borosilicate glass which virtually eliminates migration of contaminants contained in normal glass (which is itself a liquid) into precious oud oils over time. Most importantly, we have fitted our v-vials with inverted polycone inserts as shown which provide an ultra-tight seal without allowing oil to seep into cap threads. The1.5 ml and 10 ml vials are graduated as shown to allow for more precise determination of remaining product volume.
The convenient 0.75 ml size V-vials will easily hold 0.75 gm of oil (which takes up more volume than 0.75 ml because oils are lighter than water), but can be used to carry even smaller amounts of product to work or for travel without fear of theft or contamination of your larger bottles.
Our 0.2 ml v-vials are designed to be used to hold samples or for traveling. Oil samples will last for long periods of time in these vials without degradation, as they are fabricated using low reactivity polypropylene and are fitted with HDPE (high density polyethylene) applicators. We use these same vials to ship our most expensive and precious product samples, and our customers tell us that after a year or more the products still smell great.
CAUTION: While these vials will hold more than 0.2 ml, the applicators are not screwed onto the vials, rather they are pushed on, so if these are filled above 70%, the cap may eventually pop off due to air pressure created in the space between the top of the liquid and the cap when the cap is inserted. Also, oil will effectively "lubricate" the neck of the vial, which could further contribute to the cap popping off. These are not problems unless the vials are overfilled, and we have never had one of them leak during transit to our customers.
Our glass V-vials are not used with applicators which are placed back into them after contacting skin. Glass V-vials are perfect for those who do not wish to contaminate their costly oils over time with dead skin cells, lotions, soaps, perfumes and other biochemical debris which could be picked up with each contact of the typical rough-surfaced plastic applicators with skin. As such, each V-vial will be shipped with one borosilicate glass applicator rod. If used and cleaned properly our glass applicators can virtually eliminate oud contamination which may change an oil's scent profile over time. from continuous contact during storage with typically rough-surfaced plastic applicators which have previously contacted skin.
NOTE: TWIS does not take responsibility for improper use of these vials. If used with care and the applicators are wiped clean after each use, your oils should last for many years in an uncontaminated state and should not change in scent profile for reasons other than the natural aging process.
