Microsolv Technology Corporation Caps, Screw Top, with PTFE, ultra-pure Septa, fitted in "knurled", polypropylene, Black Caps. For use with 9-425mm thread, 12x32mm autosampler vials. 100/PK
This PTFE (only) Septa is for single injections or non-volatile samples as it will not reseal.
Microsolv Technology Corporation Caps, Snap Top, with Butyl Rubber / Tefzel Septa, fitted in smooth, soft polyethylene, Natural Transparent Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. 100/PK.
Soft polyethylene caps are more pliable than other Snap Caps and are easier to place on the vial. Popular choice when using a large number of caps at one time. These caps may not seal as well as other Snap Caps and should be used with sample solvents with low volatility. Butyl Rubber with Tefzel is a lower cost Septa but inert enough for most applications.
Microsolv Technology Corporation Caps, Screw Top, Solid, with a Silicone Rubber / Polypropylene liner, in "knurled", closed Black Caps. 1000/CS
This item has a minimum order quantity of 20 packs per supplier requirements.
Polyfluoroalkyl Substances (PFAS) can be tested or stored in our autosampler vials using these caps. The silicone rubber (for optimal sealing), and polypropylene fitted liners (for inertness) are excellent for storage of your sample before or after chromatography. These caps do not contain PTFE.
Enzo Life Sciences Matrix Metalloproteinase-8 (MMP-8) fluorometric drug discovery kit (1x96wells)
A QUANTIZYME Assay System. The MMP-8 Fluorometric (also known as fluorimetric) Drug Discovery Kit is a complete assay system designed to screen inhibitors of matrix metalloproteinase-8 (MMP-8, neutrophil collagenase, collagenase-2) using a quenched fluorogenic peptide: OMNIMMP fluorogenic substrate Mca-Pro-Leu-Gly-Leu-Dpa-Ala-Arg-NH2. Mca fluorescence is quenched by the Dpa group until cleavage by MMPs at the Gly-Leu bond separates the two moieties. The assays are performed in a convenient 96-well microplate format. Also included are active enzyme, a prototypic control inhibitor (NNGH3), and a detailed instruction booklet. Alternative name: Neutrophil collagenase, Collagenase 2. Applications: Fluorescent detection, HTS Activity assay.
Microsolv Technology Corporation Caps, Snap Top, with Soft-Guard, White Silicone Rubber / Red PTFE Pre-Slit Septa, fitted in smooth, polyethylene, Yellow Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. 1000/CS.
Soft-Guard™ Septa provide easier penetration of autosampler needles and better resealing than other brands, for longer instrument up-time and fewer missed injections. Pre-Slit Septa are normally recommended for Waters Alliance and Acquity instruments.

Microsolv Technology Corporation Caps, Snap Top, with 1.00mm thick, Red PTFE / White Silicone Rubber / Red PTFE Septa, fitted in smooth, soft polyethylene, Natural Translucent Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. 100/PK.
Soft polyethylene caps are more pliable than other Snap Caps and are easier to place on the vial. Popular choice when using a large number of caps at one time. These caps may not seal as well as other Snap Caps and should be used with sample solvents with low volatility. This septa was designed for specific, older instruments such as Agilent 1050 and to provide extra cleaning when "wiping" a needle. Also provides a small degree of better resealing after injection compared to Silicone Rubber / PTFE Septa.
