SKU: WAT094170 Low Volume 6 x 29 mm Insert, 300 µL Volume, with Plastic Spring 100/pk
Vial inserts are a solution in applications where there is limited sample volume. Choose the appropriate volume insert for your sample volume and vial size.
Low Volume 6 x 29 mm Insert, 300 µL Volume, with Plastic Spring 100/pk
When working with low sample volumes, vials and other lab equipment can require a special Low Volume Insert to help appropriately distribute any solution and make it accessible to needles and other applications. These inserts are made to include a plastic spring in order to make sample extraction and analysis easier on chromatographers. When samples are sensitive to light or oxygen, these inserts can help prevent exposure and maintain their properties.
This insert offers a volume capacity of 300 µL and can be used with a range of products like the Clear Glass 12 x 32 mm Screw Neck Vial, 2 mL Volume, 100/pk. Other inserts are available with varying volumes, dimensions, and materials. Based on your sample volume and chosen column, the correct insert can be chosen for any application.
Inserts can be made with deactivated glass to be used with similar vials when it is necessary to eliminate adsorption of compounds onto the glass surface, like when working with biological or pharmaceutical compounds, natural products, pesticides, or herbicides. This deactivated glass offers surface modification which is permanent, resulting in an indefinite shelf life.
Should I Use Polypropylene Or Glass Vials And Inserts?
Waters’ sample analysis products are often available in both glass and polypropylene options. Polypropylene is a form of plastic designed to avoid some of the challenges of glass, including weight, breakage, surface inertness, and disposal costs.
Glass vials are the most common method of storing and analyzing samples in a lab. Due to their relatively inert surface, they are compatible with many different solvent systems and are available in a variety of sizes and styles. Glass is also able to withstand temperatures up to 500 degrees C for autoclaving and derivatization applications. Many people prefer the pure, clear surface of a glass vial to better inspect the contents for contamination or degradation.
However, Waters also offers a wide range of polypropylene vials. These vials do not risk breakage and are non-reactive with most sample chemistries. The material is compatible with a number of solvents and can even be preferable for some applications, including proteins and IC applications. Additionally, pH-sensitive samples may be best stored in the plastic alternative.
