ASTM Conical Oil Test Tube for OLEUM (Each)

The Z600-OL-CT is the ASTM conical oil test tube for the Hermle OLEUM Oil-Test Centrifuge (Z600-OL chassis), sold as each. The ASTM conical tube is the standard glass-tube format specified by ASTM oil-testing protocols (ASTM D96, D4007, D2273) for water and sediment determination in petroleum products. The conical-tip geometry concentrates separated water and sediment phases at the tube tip for direct volumetric measurement against the tube's graduations. Used with the Z600-OL-CTC felt-cushion adapter to seat the tube correctly in the Z600-OL-BUK round bucket.

Key Specifications

Compatibility & When to Order This SKU

Tube pairing: OLEUM Oil-Test Centrifuge workflow only. Order this SKU when:

1. Initial workflow setup. When commissioning an OLEUM Oil-Test Centrifuge for ASTM D96 / D4007 / D2273 conical-tube workflows, order tubes per the workflow's batch size (typically 4 tubes per cycle for full 4-bucket loading).
2. Workflow-recurring replenishment. ASTM oil test tubes see workflow-recurring use (one tube per sample, typically discarded after analysis or after a finite number of cleaning cycles per ASTM protocol).
3. Mixed conical / pear-shaped workflow. When the lab runs both ASTM conical (this tube) and ASTM pear-shaped (Z600-OL-PT sister tube) workflows, stock both formats per workflow protocol.
4. Replacement. If a tube is broken or has reached service life.

ASTM Oil-Test Tube Format

The Z600-OL-CT is the ASTM-conformant conical oil test tube, distinct from generic 100 mL conical centrifuge tubes by its:

• Graduated scale. Engineered tube graduations for direct volumetric measurement of separated water/sediment phase per ASTM protocol
• Conical-tip geometry. Engineered taper that concentrates water and sediment at the tip for visual measurement
• Glass material. Required by ASTM protocols for chemical compatibility with petroleum solvents and sediment analysis reagents
• ASTM dimensional spec. Tube dimensions match ASTM-specified envelopes for protocol-compliant analysis

Generic 100 mL conical tubes are not interchangeable with the ASTM Z600-OL-CT for ASTM-compliant oil-testing workflows.

Application Profile

ASTM D96: water and sediment in crude oil by centrifugation: petroleum-quality testing in refineries and crude-oil processing facilities.

ASTM D4007: water and sediment in fuel oil by centrifugation: petroleum-fuel-quality testing in refineries, fuel-distribution facilities, and fuel-quality field labs.

ASTM D2273: trace sediment in lubricating oils by centrifugation: lubricating-oil quality testing in automotive, marine, industrial machinery, and petroleum-product manufacturing labs.

Educational and training petroleum-engineering programs. Petroleum-engineering curricula teaching ASTM oil-testing methodology require ASTM-conformant tubes for protocol-fidelity teaching.

Field oil-quality testing labs. Field-deployed oil-testing labs running ASTM workflows on the OLEUM platform.

Ordering & Configuration

Use with Z600-OL-CTC felt-cushion adapter: the ASTM conical tube is seated in the Z600-OL-CTC felt-cushion adapter inside the Z600-OL-BUK round bucket. The adapter cushions the glass tube during centrifugation and ensures correct tube positioning for protocol-compliant analysis.

Symmetric loading. The OLEUM rotor's 4-bucket swing-out configuration requires 4 ASTM conical tubes per cycle (one per bucket); pre-balance pairs by sample mass before each spin.

Tube cap / stopper confirmation. ASTM conical tubes are typically capped per ASTM protocol before centrifugation; confirm cap integrity before each spin.

Z600-OL-CT ships as each. Buy per workflow batch size, typically 4 tubes minimum per cycle for full 4-bucket loading, with replenishment quantity sized to workflow throughput and tube lifetime per ASTM protocol.

Confirm at quote: chassis pairing (Z600-OL OLEUM in inventory), workflow protocol (ASTM D96, D4007, D2273), tube quantity needed for workflow throughput, adapter pairing (Z600-OL-CTC felt-cushion adapter availability), and lead time.

Warranty: Per Hermle's terms for ASTM oil-test tube glass. Confirm at quote. Glass tubes are typically not under the standard 5-year drivetrain warranty (which covers chassis and rotor mechanical components) but follow Hermle's separate consumable-glass terms.
