Description
UltraB. screw caps with bore hole, PP, ND9 are polypropylene ND9 screw closures fitted with a silicone/PTFE slotted septum for autosampler vials and sample bottles. According to the manufacturer description, the configuration is UltraB. screw caps with bore hole, PP, ND9, septum Silic./PTFE, slotted, 1,5 mm 45°, so septum thickness is 1,5 mm at 45° hardness in a slotted silicone/PTFE build. The bore-hole cap design supports needle access through the septum on matching ND9 neck finishes used in laboratory vial systems. Pack size is 100 pc(s) with a pack weight of 0,033 kg, suitable for stocking beside related screw-cap and vial consumables. Product placement covers labware, laboratory glass, vessels, consumables, autosampler vials and sample bottles. These UltraB. caps from manufacturer ROTH SELECTION give a defined PP body plus the thicker slotted silicone/PTFE septum noted above. Select them when ND9 UltraB. screw caps with a 1,5 mm silicone/PTFE slotted septum at 45° are specified for sample handling. Source data limit claims to material, neck size, septum type, thickness, hardness and unit quantity, enabling straightforward comparison with other ND9 bore-hole screw-cap options in the same range.

Questions about UltraB. screw caps w. bore hole, PP,ND9, Septum Silic./PTFE, slotted, 1.5 mm 45°
What is this article?
UltraB. screw caps w. bore hole, PP,ND9, Septum Silic./PTFE, slotted, 1.5 mm 45° is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Vial caps & septa, inside Vials, caps & septa, in Chromatography equipment.
A vial cap and a septum have to match the vial neck: crimp, screw or snap, and the diameter. The septum material, PTFE/silicone or rubber, decides chemical resistance and how many times a needle can pierce it. A septum that sheds into the solvent becomes ghost peaks.
An autosampler vial is the small closed bottle a chromatograph picks up. The neck is crimp, screw or snap, and the cap and the septum have to be that neck. The septum is the part the needle pierces. A soft septum reseals. A septum that is wrong for the solvent swells or sheds particles into the sample. Inserts reduce the volume when the sample is scarce. The separation they feed is described with IUPAC names and PubChem data.
