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.

The Z600-OL-CT is the ASTM-conformant conical oil test tube — distinct from generic 100 mL conical centrifuge tubes by its:
Generic 100 mL conical tubes are not interchangeable with the ASTM Z600-OL-CT for ASTM-compliant oil-testing workflows.
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.
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.
OLEUM Oil-Test Centrifuge tube and adapter family (Z600-OL chassis):
- Z600-OL-CT (this product) — ASTM conical oil test tube (each)
- Z600-OL-CTC — Felt-cushion adapter for ASTM conical oil test tube
- Z600-OL-PT — ASTM pear-shaped oil test tube (each)
- Z600-OL-PTC — Felt-cushion adapter for ASTM pear-shaped oil test tube
- Z600-OL-BUK — Round bucket for OLEUM rotor (sold separately)
- Z600-OL-INS — Bottom insert for round bucket
- Z600-OL-COM — Complete OLEUM bundle (chassis + buckets + inserts)
Pick the conical tube (Z600-OL-CT + Z600-OL-CTC adapter) for ASTM workflows specifying conical-tip geometry; pick the pear-shaped tube (Z600-OL-PT + Z600-OL-PTC adapter) for ASTM workflows specifying pear-shaped geometry.
