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.
