Pertanyaan umum tentang FINNERAN dari 3G Electric.
What glass type are FINNERAN chromatography vials made from?
FINNERAN glass chromatography vials are manufactured from colorless glass, typically Type I borosilicate glass. This material is chosen for its chemical resistance and low extractable levels, which minimize contamination of samples during storage or analysis. The glass is suitable for use with a wide range of solvents and reagents common in GC and HPLC applications. The vials are not specified as being made from soda-lime glass or other types, so for applications requiring specific glass properties, verify compatibility with your analytical conditions.
Are FINNERAN vials compatible with standard autosampler systems?
FINNERAN vials are designed with standard body diameters and closure sizes that are commonly used in autosampler systems. For example, vials with 8 mm, 12 mm, 15 mm, 21 mm, and 27 mm body diameters correspond to typical autosampler tray dimensions. The screw closure sizes (8-425, 13-425, 18-400, 24-400) match standard cap threads. However, compatibility depends on the specific autosampler model and its requirements for vial height, neck design, and cap type. Always cross-reference the vial dimensions with your instrument's specifications before ordering.
Do FINNERAN vials come with closures included?
FINNERAN offers both vials without closures and vials that include closures. For example, SKU 49AR68 is a shell vial with plugs included, and SKU 49AR70 is a vial with a polypropylene cap included. Other SKUs, such as 49AP67 and 49AN27, are supplied without closures. When selecting a product, check the product description to confirm whether a closure is included. If you need a specific cap type (e.g., polypropylene, PTFE-lined), verify the material and compatibility with your sample matrix.
What is the volume range available for FINNERAN vials?
FINNERAN glass chromatography vials are available in volumes from 0.3 mL to 60 mL. The smallest vial in the product range is 0.3 mL (SKU 49AM57), and the largest is 60 mL (SKU 49AP84). Intermediate sizes include 1 mL, 2 mL, 4 mL, and 14.78 mL. This range covers applications from micro-sample analysis to larger volume storage or preparation. The actual fill volume may be less than the nominal capacity due to headspace requirements for closure or injection.
What closure sizes are used on FINNERAN vials?
FINNERAN vials feature screw closure sizes of 8-425 mm, 13-425 mm, 18-400 mm, and 24-400 mm. These sizes correspond to standard thread dimensions used in laboratory vials. The 8-425 mm size is common on smaller vials (e.g., 0.3 mL, 2 mL), while larger vials (e.g., 4 mL, 14.78 mL, 60 mL) use 13-425 mm, 18-400 mm, or 24-400 mm closures. Ensure that the closure size matches your available caps or septa for a proper seal.
Can FINNERAN vials be used for sample storage in addition to chromatography?
Yes, FINNERAN vials can be used for general sample storage, provided the glass and closure materials are compatible with the sample. The vials are made from colorless glass, which offers limited UV protection, so light-sensitive samples may require amber glass or additional shielding. The polypropylene closures included with some sets are suitable for many organic solvents and aqueous solutions, but for aggressive chemicals or long-term storage, verify chemical resistance. The vials are not specifically rated for high-pressure or vacuum applications.
