Several styles are offered including flat bottom, concial inserts with a top spring or a bottom spring, and concial without springs. Glass inserts are sold in two diameters for 2mL vials; one for standard opening (4.6 mm) vials and another for large opening (6 mm). The volume will vary depending on the length and the style of insert.
Screw caps size 22-400 is made from Urea with Poly-seal cone liner. Caps are packed separately in polyethylene bags of 100. Vial measures 28mm diameter x 57mm height (with cap off), and 61mm height (with cap on). Size 20 ml. 2. High Density Polyethylene (HDPE) Vials. Opaque, high-density polyethylene vials are economically priced.
Concentrations can be as low as 0.2 mM, or as high as 150 mM, or more. In general, increasing the concentration or chain length increases retention times. High concentrations (>50%) of acetonitrile or some other organic solvents can precipitate ion pair reagents. Also, some salts of ion pair reagents are insoluble in water and will precipitate.

Injection volume is wrong randomly, e.g. 3 vials in a row are fine, then 2 not, the next is fine and then the next 4 wrong again. Same solvent for all samples, few % AcN in water.
10-425 screw thread caps, septa and vials provide a wider opening to reduce potential needle bending/breaking during sampling. Caps are made of high quality polypropylene to exact manufacturing tolerances and lined in a controlled manufacturing environment. Cap colors are available in black only.
Quality vials are essential for reliable analytical results. All Waters Certified Vials are tested by LC or LC/MS to assure quality and cleanliness. The test results confirm the vials, cap and septa have been properly manufactured, handled and packaged, and are free from any potential contaminants which could result in chromatographic ghost peaks.
