SOR SENSOR Sampling System Bottle, Cap and Septum Supplies
SOR Controls Group / SENSOR Sampling Systems supplies a complete range of industrial-grade bottles, hole-punched caps, and laminated septa engineered specifically for closed-loop grab sampling systems in chemical plants, oil refineries, and petrochemical complexes. Standard laboratory vials and caps are unsuitable for heavy-duty industrial needle systems because laboratory cap holes are too small (causing needle interference and binding) and standard septa are too thin (resulting in tearing, core-cutting, and sample leakage). SENSOR caps are punched in-house with precisely dimensioned center holes (.500" to .750") to provide smooth clearance for dual-needle process and vent assemblies. SENSOR septa are manufactured from premium 100-mil virgin silicone bonded to an inert PTFE (Teflon) film barrier, delivering excellent chemical resistance, low bleed, and superior self-resealability when punctured. Available in Clear Flint Glass (up to 121 °C / 249 °F), Translucent HDPE (shatterproof up to 71 °C / 160 °F), and Heavy-Duty Clear Borosilicate Glass (thermal shock resistant up to 500 °C / 900 °F), in volumes from 1 oz (30 ml) to 32 oz (1000 ml).
In-house precision punched cap holes (.500" to .750") designed specifically for industrial dual-needle sampling
Heavy-duty 100-mil silicone septa with chemically inert PTFE (Teflon) lamination for zero sample contamination
Superior self-resealability balances needle penetration resistance with complete volatile liquid containment
Eliminates needle bending, core-cutting, and cap binding common with standard thin laboratory supplies

Operational & Handling Guidelines
Always verify needle shroud alignment before pushing the bottle upward into the sampling needles.
Do not reuse septa for critical volatile sampling; discard punctured septa to prevent sample leakage.
Use Borosilicate glass (BSC...BTS) for high-temperature sample streams or severe thermal shock conditions.
HDPE plastic bottles are recommended for caustic liquids or rough plant environments where glass breakage is a hazard.
Industrial Needle System Compatibility
In closed-loop grab sampling systems, the sample bottle is pushed upward into a protective shroud where a dual-needle assembly (process dispensing needle and vent needle) pierces the cap septum. Standard commercial laboratory bottles and caps frequently cause sampling failures: their pre-punched holes are too small, causing the needles to scrape or jam against the plastic cap, and their thin septa easily tear or 'core', allowing hazardous product to vent into the shroud or leak during transit.
SENSOR caps are punched in-house with generous, centered guide holes specifically calibrated for industrial needle profiles. Combined with 100-mil thick PTFE-lined silicone septa, the assembly ensures low insertion force, zero needle deflection, and tight elastomeric resealing after withdrawal.
Heavy-duty 100-mil silicone body provides robust mechanical memory for complete self-sealing after needle extraction
Virgin PTFE Teflon facing shields the elastomer from corrosive attack and prevents chemical leaching into the sample
Precision hole punching leaves clean edges with zero flash or plastic burrs to contaminate samples
Compatible with SENSOR Needle Evacuation Systems (NES) and all standard industrial sampling needle blocks

Quality Assurance & Sample Integrity
In environmental compliance, custody transfer, and refinery quality control, sample contamination or volume loss due to poor bottle sealing can result in costly re-tests or regulatory non-compliance. SENSOR bottle supplies maintain consistent dimensional tolerances across every batch.
All septa are pigment-free to eliminate chemical leaching and volatile organic extraction during high-sensitivity gas chromatography (GC) and mass spectrometry (MS) laboratory evaluations.
100% inspected for uniform punch diameter, thickness consistency, and liner adhesion
Supplied in sealed clean-pack polyethylene bags and protective carton packaging
Custom sizes, amber UV-blocking glass, and specialty septa formulations available upon request
