Spare Bottom Inserts for Z600-OL-BUK (2/pk)

The Z600-OL-INS is the spare bottom insert for the Hermle Z600-OL-BUK round bucket on the OLEUM Oil-Test Centrifuge (Z600-OL chassis) — sold as a 2-pack. The bottom insert sits at the base of the bucket and provides tip-cushioning for the ASTM glass oil test tube during high-RCF processing. Default-included in the Z600-OL-COM bundle (4 inserts shipped with the chassis); this SKU is the spare or replacement insert. The 4-place rotor takes 4 inserts total; full-insert replacement requires 2 packs (4 inserts).

Key Specifications

Compatibility & When to Order This SKU

Insert pairing — Z600-OL-BUK round bucket only. Order this SKU when:

1. Replacing a damaged or worn bottom insert from the original Z600-OL-COM bundle — order 1 pack for 2-insert replacement, 2 packs for full 4-insert replacement.
2. Spare insert inventory for facilities running heavy-duty oil-testing workflows where insert wear from continuous tube-tip impact justifies a spare set.
3. Service-life replacement — if the original insert set has reached the manufacturer's recommended service interval and full replacement is appropriate.

Note on procurement: The Z600-OL-INS is NOT required for the initial Z600-OL-COM bundle purchase — that bundle ships with 4 inserts included. Order this SKU only as a replacement / spare scenario.

Why a Bottom Insert Matters for OLEUM Glass Tubes

ASTM oil test tubes are glass. Without a bottom insert, the glass tube tip would impact directly against the metal bucket interior at the start of each spin cycle (and potentially at the deceleration phase) — a stress concentration that risks tube-tip cracking, tube failure during high-RCF operation, and oil-sample loss into the rotor chamber.

The Z600-OL-INS bottom insert provides:

• Tip-impact cushioning — protects the glass tube tip against direct metal-on-glass contact
• Vibration damping — reduces stress on the tube structure during continuous rotation
• Correct tube-depth positioning — ensures the tube sits at the protocol-correct depth for graduated-scale alignment

The insert is a workflow-recurring replacement item — typical OLEUM operation will see insert wear on the manufacturer-recommended service interval.

Application Profile

ASTM D96 / D4007 / D2273 oil-testing workflows on OLEUM — continuous operation in petroleum-quality testing, fuel-quality testing, and lubricating-oil testing labs.

Refinery petroleum-quality testing — refineries running daily ASTM oil-testing workflows benefit from spare insert inventory for rapid replacement.

Field oil-quality testing labs — field-deployed oil-testing labs running ASTM workflows benefit from spare insert inventory for field-deployment scenarios.

Service-life replacement — facilities operating OLEUM chassis past the manufacturer-recommended service interval should plan insert replacement as part of routine maintenance.

Cross-site spare insert inventory — facilities running multiple OLEUM chassis (multi-site refineries, multi-region oil-quality testing operations) benefit from spare insert inventory for rapid replacement.

Ordering & Configuration

4-bucket symmetric loading is mandatory; all 4 buckets must have matching insert configurations for symmetric balance.

Insert inspection. Inspect bottom inserts before each cycle — the insert should be intact, free of cracks, and seated correctly at the bucket base. Replace when insert shows wear, cracking, or compression.

Z600-OL-INS ships as 2 bottom inserts. Z600-OL-BUK round buckets (also included by default in the Z600-OL-COM bundle) are sold separately for replacement.

Required for operation:

• Z600-OL-COM bundle (chassis + 4 original buckets + 4 original inserts) — primary purchase
• For insert replacement: 1 or 2 packs of this SKU depending on replacement scope

Confirm at quote: chassis pairing (Z600-OL OLEUM in inventory), bucket pairing (Z600-OL-BUK in inventory), replacement scope (2-insert vs 4-insert replacement), service-history rationale (wear, service interval, spare inventory), and lead time.

Warranty: 5-Year Hermle warranty (3 years full + 2 years drivetrain) on the inserts.

OLEUM Oil-Test Centrifuge accessory family (Z600-OL chassis):

- Z600-OL-INS (this product) — Spare bottom inserts for round bucket

- Z600-OL-BUK — Spare round buckets

- Z600-OL-CT / Z600-OL-PT — ASTM oil test tubes (conical / pear-shaped)

- Z600-OL-CTC / Z600-OL-PTC — Felt-cushion adapters for ASTM tubes

- Z600-OL-COM — Complete OLEUM bundle (chassis + buckets + inserts)

The Z600-OL-INS is the spare/replacement bottom insert for the OLEUM workflow — order only when the original Z600-OL-COM bundle's 4 inserts need replacement or when spare inventory is justified.
