The Range

Lab plastics for the full sampling chain.

Eight products across four families — plus a custom injection-moulding service for partners outside the fluid-analysis line. Every component is made to the same Ultra-Clean manufacturing standard, ready to integrate cleanly into an oil-, fuel-, water- or coolant-analysis workflow.

01 — Sample Bottles

Ultra-Clean Hot Process PET sample bottles.

Aoki ISBM-formed, Hot-Process conditioned, in-line capped. The reference product family the Fluid Science line was built around — three configurations covering ribbed and smooth-walled use cases.

4 oz

4 oz Sample Bottle

The workhorse used-oil bottle for handheld and bench analyser workflows. Tamper-evident cap, hot-oil tolerant, sized to the standard MiniLab / FluidScan sample volume.

5 ozMost Popular

5 oz Sample Bottle

Slightly larger retain volume for full ASTM-spectrum work and split-sample arbitration. The default volume across most condition-monitoring programmes on the distribution network.

Fluid Science 4 oz smooth-walled Ultra-Clean sample bottle
4 oz · Smooth

4 oz Smooth Sample Bottle

Smooth-walled variant for clean label application and visual sample inspection. Same Ultra-Clean Hot Process PET chemistry as the standard 4 oz — chosen wall geometry, identical performance.

02 — Mailer Bottle

PP mailer bottle — transit-grade.

Rugged polypropylene field bottle engineered for the courier reality of Sub-Saharan logistics — drop, pressure, and temperature tested for site-to-lab shipping without compromise.

Fluid Science PP mailer bottle for site-to-lab sample logistics
Mailer

Mailer Bottle

Polypropylene field bottle for remote-site sampling and site-to-lab dispatch. Leak-proof closure, oil- and fuel-compatible polymer wall, drop-tested for satchel and courier carriage across mining, refinery, and inspection-house chains.

PP · Drop-tested · Leak-proof closure · Fleet-grade
03 — Vials & Sample Cups

Analyser-matched vials and RDE sample cups.

Cleanroom-moulded consumables for the lab bench itself — purpose-sized to the analytical methods they feed. FerroCheck for ferrous wear, FDM for fuel-dilution, and rotating-disc-electrode cups for SpectrOil-series elemental analysers.

Fluid Science FerroCheck vials for ferrous wear monitoring
FerroCheck

FerroCheck Vials

Purpose-moulded vials for the Spectro FerroCheck ferrous-wear analyser. Cleanroom-produced under the same Ultra-Clean atmospheric protocol used for the bottle line — zero ambient ferrous contamination.

FS-302-FDM
Fluid Science FDM (Fuel Dilution Meter) vials
FDM

FDM Vials

Vials sized to the Fuel Dilution Meter workflow — sealed, hydrocarbon-compatible polymer chemistry that preserves vapour-fraction integrity through the analytical hold time.

FDM-fit · Vapour-tight · Hydrocarbon-compatible
FS-302-RDE
Fluid Science RDE sample cups for rotating-disc-electrode oil analysers
RDE

RDE Sample Cups

Disposable rotating-disc-electrode sample cups for the SpectrOil-series elemental analysers. Heat-resistant and flame-retardant polymer compound — engineered to survive the arc-discharge thermal load without distortion or ignition. Moulded to the analyser carousel geometry; sized for single-aliquot use and rapid turnaround.

SpectrOil-fit · Heat-resistant · Flame-retardant · Single-use
04 — Pipettes

Disposable transfer pipettes.

Sterile single-use LDPE transfer pipettes for analyser feed and bench dilution. Cleanroom-moulded under the same Ultra-Clean protocol as our bottles and vials.

FS-510-003
Fluid Science 3 ml disposable LDPE transfer pipette
3 ml

3 ml Pipette

Mid-volume sterile transfer pipette for typical analyser feed quantities and sample dilution workflows. Graduated, one-handed snap-bulb, packed in cleanroom-sealed sleeves.

3 ml · LDPE · Single-use · Graduated · Sterile
05 — Custom Injection Moulding

Injection moulding for other industries.

The same Arburg presses and Aoki ISBM lines that build the Fluid Science range are available for contract manufacturing. If your part fits our envelope — and your volumes justify a run — we'll quote it.

What we mould

Containers, closures, and technical parts

Bottles, vials, caps, closures, racks, holders, and small-to-medium technical components in PET-G, HDPE, LDPE, PP and PE. Cleanroom-compatible runs for pharma-adjacent and laboratory-adjacent industries; standard runs for everything else.

Who we mould for

Industries we already serve

Cosmetics & personal care · Pharmaceutical packaging · Food & beverage components · Industrial chemicals · Agricultural & veterinary · Automotive aftermarket consumables · Branded promotional containers.

How it works

Specs in, parts out

Send a drawing, sample, or written spec to sales@fluidscience.co.za. We'll come back with tooling feasibility, material recommendation, MOQ, lead time, and a quote on the first qualified production run.

Out-of-Stock Specs Welcome

Need a non-standard bottle, vial, or closure?

The Fluid Science line is set up to engineer back from analyser geometry. If your analytical method calls for a non-standard volume, thread, or closure type — or your industry needs something else entirely — we'll prototype it on our own tooling and quote you a production run.
