Every machine on the Fluid Science floor was chosen to eliminate a specific contamination vector that destroys fluid-analysis data. This page is the technical walkthrough — press by press, polymer by polymer, the way an engineer would want it explained.
The Allrounder Comfort A is Arburg's all-electric workhorse. Replacing hydraulic actuation with servo-electric drives eliminates the largest contamination vector in conventional injection moulding: fugitive hydraulic oil aerosols carried into the moulding cell on every shot.
The Gestica control system orchestrates clamp, screw, and injection in lockstep, while Arburg's Fill Assist function delivers shot-to-shot repeatability inside ±0.01 g — the foundation of dimensionally consistent sample-bottle necks, threads, and seal surfaces.
Aoki's injection stretch blow moulding (ISBM) machinery is the Japanese gold standard for clear-PET-G sample-bottle production. Unlike two-stage blow moulding — where preforms are produced, stored, transported, and re-heated — Aoki's single-stage process forms the preform and blows the bottle inside a single thermal pass.
The advantage for fluid analysis: the bottle interior never encounters open air between forming stages, never sits in storage where dust accumulates, and never re-heats in a cycle that risks plasticiser migration. The result is crystal-clear PET-G containers with cleanroom-grade interiors straight off the press.
Used-oil samples are drawn hot. An oil sampler valve on a haul truck, a turbine bearing housing, a compressor crankcase — these all extract lubricant at 60–90 °C. A sample bottle that softens, deforms, or leaches plasticiser at that temperature compromises every downstream analytical reading.
The Aoki Proprietary Hot Process is a thermal conditioning stage applied immediately after Aoki ISBM. It cross-tunes the PET-G crystallinity so the finished bottle retains dimensional stability and chemical inertness at hot-oil extraction temperature — without compromising clarity or seal-surface integrity. The conditioning hold is held at a verified 125 °C through HB-Therm closed-loop temperature control across the production cycle.
Atmospheric purity is only as good as the moment the closure goes on. A bottle that's been moulded, conditioned, and inspected — and then sits open on a packing bench for ten minutes — has lost every contamination guarantee the earlier stages bought.
Fluid Science seals each bottle on the production line itself with a Kinex Cappers in-line capping system. At a verified 62 caps per minute, with closed-loop torque, presence detection, and cap-reject diagnostics on every cycle, the interior of every Fluid Science bottle is sealed within seconds of leaving the Hot Process stage.
The result: a bottle whose interior atmosphere is the Class 0 oil-free air of the Aoki blow station — not the warehouse, not the packing room, not the courier truck.
The integrity story doesn't stop at the bottle. Sampling kits — a custom-printed box, a foam insert, an instruction card, a return label — usually involve three or four outside vendors and a tooling lead time of weeks.
Fluid Science brings the entire kit-packaging stack in-house. The HP Latex R530 rigid-and-flexible printer produces full-colour, oil-resistant, food-grade-rated branding on board stock up to 64" wide. Jwei CNC cutting then forms the box geometry — any geometry, no tooling required.
For our clients this means: custom-branded sampling kits sized to the application, ready for dispatch in under a week, with zero up-front tooling cost. Mining houses, refineries, fleet operators, and inspection agencies all receive kits in their own livery.
The Ultra Clean Protocol is the compliance specification all Fluid Science sample-grade plastics are produced to. It is the contractual integrity baseline we hold the manufacturing line to — every shift, every shot.
All-electric Arburg Allrounder Comfort A — no hydraulic fluid in the press cell. Gestica with Fill Assist holds shot mass inside ±0.01 g.
Certified Class 0 oil-free compressed air at both injection and blow-moulding. Hydrocarbon and particulate ingress is removed at the source.
Aoki ISBM plus Hot Process tunes PET-G for hot-oil extraction. Automated in-line capping seals every bottle on the press itself.
HP Latex print and Jwei CNC bring kit-box manufacturing in-house. Custom branding with zero tooling lead time, no broken chain of custody.
