Mettler Toledo Empty Refill Rack GPR Universal Tip 300 ul 0/8 Case of 40 Racks

Mettler Toledo Rainin Empty Refill Racks for 300 µL Universal Pipette Tips (30397667) – Case of 40

The Mettler Toledo Rainin 30397667 is an automation-grade, reusable structural laboratory component designed to support high-volume eco-efficient tip refill pipelines. Engineered specifically for 300 µL universal-fit (traditional bevel/shaft design) pipette tips, these empty racks serve as the rigid structural base for Rainin Green-Pak® and SpaceSaver™ nested tip inserts. Injection-molded from robust, high-purity virgin polypropylene, these heavy-duty housings are built to withstand repetitive autoclave cycles, providing high-throughput laboratories with a reliable method to reduce solid plastic waste.

Technical Performance & Design

• Universal-Fit Deck Stabilization: Features a precision-molded internal grid deck engineered to receive and lock down 300 µL universal tip refill plates, eliminating vertical deck flex and ensuring secure tip pick-up under multi-channel pipetting pressures.
• Hinged-to-Lift-Off Dual-Action Lid: Outfitted with an adaptable transparent cover that can function as a standard swinging hinge or can be detached entirely as a lift-off lid to accommodate tight bench spaces or automated liquid handler enclosures.
• Autoclave Thermal Resilience: The high-density polymer matrix is thermally rated to endure standard autoclave sterilization loops at 121°C (15 psi for 15–20 minutes) without warping, cracking, or losing dimensional tolerances.
• Secure Mechanical Front Latch: Equipped with a snap-locking front clasp that prevents accidental opening during transit across facilities while enabling smooth, single-handed opening at the workstation.

Key Benefits & Applications

• Environmental Solid Plastic Reduction: Significantly cuts down a facility's laboratory carbon footprint and environmental waste stream by substituting standard single-use tip boxes with a durable, multi-use rack architecture.
• High-Throughput Refill Infrastructure: Provides the foundational benchtop organization required to convert a facility to space-saving nested inserts, maximizing storage space inside supply rooms and laminar flow hoods.
• Chemical and Sanitizer Resistance: The non-reactive poly-resin construction stands up to rigorous chemical wipe-downs using 70% Isopropyl Alcohol (IPA), ethanol, or mild surface decontaminants without clouding or becoming brittle.
• ANSI/SLAS Footprint Alignment: Complies with universal microplate footprint dimensions to fit securely into standard benchtop organization wells, microplate validation nests, and automated station racks.
