The filter size depends highly on the filtration volume. For small volumes (< 1 ml), syringe filters with a diameter of 3 mm are used for medium volumes (1-10 ml), 15 mm and for large volumes (> 10 ml) 25 mm. Common pore sizes for UHPLC and HPLC columns with small particle sizes (< 3 µm) are 0.2 and for columns with larger particle sizes (> 3
Therefore, the 2ml snap top HPLC vial is easy to fill and increases the target area of the autosampler needle. This means that 2ml snap-top HPLC vials can protect needles. The 2ml snap-top HPLC vial size is 11.6x32mm and is compatible with most autosamplers such as Aijiren. 2ml HPLC vials are available in amber and transparent colors.
A syringe filter (sometimes called a wheel filter for its wheel-like shape) is a single-use membrane based filter cartridge, to be attached with a syringe to remove impurities in liquid solutions. This pre-filtration step is vital in preventing damage to instruments (e.g. liquid chromatography, ICP, etc.).
ND = non detectable results in μg/mL 2ml Clear Screw HPLC Vials Type II, III and NP . Type II glass is de-alkalized soda-lime glass with higher levels of sodium hydroxide and calcium oxide.Type III is soda-lime glass - cannot be autoclaved.Type NP is a general-purpose soda-lime glass used where chemical durability and heat shock are not factors..
