The Z600-OL OLEUM is a purpose-built oil-test centrifuge — a special-application Hermle instrument designed specifically for water-content and sediment determinations in petroleum, lubricant, and crude-oil samples per ASTM standards. Where a universal centrifuge separates by density across general lab workflows, the OLEUM is engineered around the conical and pearshaped oil-test tube formats that ASTM D96 / D4007 (water-and-sediment) and related petroleum-industry methods specify. Four-place swing-out rotor, 3,000 rpm / 2,213 × g ceiling matched to the ASTM-method requirements, and accessory cushions sized for both conical and pearshaped tubes. 230 V only — this is a global-market industrial QC instrument, and the petroleum-testing market standardizes on 230 V service.
Voltage options: This unit can be ordered with European voltage requirements (230V/50Hz). Contact us to order.

Application Profile
ASTM D96 / D4007 water-and-sediment in crude-oil determinations. The 100 mL tube format and 2,213 × g ceiling match the test conditions specified for water-and-sediment determinations in crude oil — this is the OLEUM's primary engineered purpose. Conical-bottom and pearshaped tubes per ASTM are accommodated with their respective bucket inserts and felt cushions.
ASTM D1796 water-and-sediment by centrifuge in fuel oils. Same instrument geometry covers the related fuel-oil method.
Lubricant and petroleum-product QC. Particulate contamination, water emulsion separation, and sediment quantification across base oils, finished lubricants, and re-refined oils.
Refinery feedstock and intermediate testing. Routine separation of brine, sediment, and water phases from crude and intermediate streams.
Recycled oil and used-oil monitoring. Used-engine-oil and re-refined-oil characterization where water and particulate contamination is the QC parameter.
Design Architecture
Purpose-built 4 × 100 mL swing-out rotor. Geometry matched to ASTM oil-test tube formats (Z600-OL-COM is the complete swing-out + buckets configuration; Z600-OL-BUK is the bucket assembly alone; Z600-OL-INS is the bottom insert for round buckets). 0–90° swing range — at full speed, the tubes orient horizontally for clean phase-boundary reads.
Microprocessor with large LCD display. Set-point and actual values shown simultaneously for speed, RCF, and time. Splash-proof foil keypad.
Single-handed operation, gloves-friendly. Operators in oil-testing labs wear nitrile or chemical-resistant gloves continuously; the keypad is engineered for that workflow.
Selection of speed in both rpm and × g in increments of 10 — important for matching ASTM-method specifications that quote either parameter.
10 acceleration and 10 deceleration profiles, including unbraked deceleration. The unbraked option preserves loose sediment layers that a braked stop would disturb.
Active imbalance identification with cut-off. Loaded oil-test tubes have non-trivial mass; asymmetric loading triggers shutdown before excursion damage.
Motor-driven lid lock. Hard interlock — the lid cannot unlock during a run, and the drive will not engage unless the lid latches.
Maintenance-free induction motor. No brush wear; engineered for daily QC-laboratory duty.
Thermal cut-out. Over-temperature protection independent of the speed-control loop.
Audio signal after stop with selectable melody — useful in QC labs running multiple instruments simultaneously where operators need to identify their cycle by ear.
99-slot program memory with quick-key for short-spin recall.
Manufactured per IEC 61010 safety standard.
Frequently Asked Questions
What is the Z600-OL OLEUM built for? ASTM oil-test determinations — water-and-sediment in crude oil, fuel oil, and lubricants (ASTM D96, D4007, D1796) using conical and pearshaped oil-test tubes.
What is the maximum speed and RCF of the Z600-OL? 3,000 rpm / 2,213 × g, matched to the ASTM oil-test method conditions.
What is the Z600-OL's sample capacity? 4 × 100 mL in the oil-test-tube swing-out format.
What voltage does the Z600-OL require? 230 V / 50–60 Hz only — there is no 120 V variant. If only 120 V service is available, a step-up transformer rated for 950 W continuous load is the workaround.
Are oil-test tubes included? No — conical (Z600-OL-CT) or pearshaped (Z600-OL-PT) tubes and their felt cushions are configuration line items ordered per the ASTM protocol.
Ordering & Configuration
Ships configured per quote. The Z600-OL body ships with operator's manual and 230 V power cord. Rotor, buckets, and tube cushions are configuration line items per the ASTM tube format the lab uses:
- Z600-OL-COM — Complete swing-out rotor with round buckets, ready for oil-test tubes (already includes Z600-OL-BUK + Z600-OL-INS)
- Z600-OL-BUK — Round bucket assembly alone (replacement or supplemental)
- Z600-OL-INS — Bottom insert for round buckets (replacement)
- Z600-OL-CT — Conical oil-test tube per ASTM (consumable)
- Z600-OL-CTC — Conical oil-test tube cushion
- Z600-OL-PT — Pearshaped oil-test tube per ASTM (consumable)
- Z600-OL-PTC — Felt cushion for ASTM pearshaped oil-test tube
Voltage: 230 V only. There is no 120 V OLEUM variant. Confirm 230 V service availability at the installation point before order. The petroleum-testing global market standardizes on 230 V; if the lab has only 120 V service, a step-up transformer rated for 950 W continuous load is the workaround — confirm in the quote.
This is a specialized industrial-QC instrument purchase. Use the quote request to specify: ASTM method(s) the lab is testing under (D96, D4007, D1796), tube format (conical, pearshaped, or both), volume of consumable tubes and cushions needed in the initial order, voltage and plug type, and whether method-validation service is required during install.
Warranty: 5-Year Hermle warranty (3 years full + 2 years drivetrain). Service network covers rotor validation and ASTM-method calibration support.
Selection note: the OLEUM is a single-purpose instrument — it's the right buy if the lab's primary workflow is ASTM oil-testing. For mixed workflows that include some oil-testing alongside general clinical or research separations, a universal centrifuge (Z327, Z446) with adapter sets covering oil-test tube formats may be a more flexible choice at the cost of being purpose-engineered for the ASTM methods.
