Rainin Pipette Tip Racks GPR-250 Empty 96 Place Racks for Green-Pak 50 Racks

Rainin GPR™ Empty Refill Racks for 200 µL / 250 µL LTS Pipette Tips (30389353) – Case of 50

The Rainin 30389353 (GPR-250 Empty Rack Series) is a commercial-grade, reusable structural laboratory component designed exclusively to support high-volume, eco-efficient pipette tip refill loops. Engineered specifically for Rainin 200 µL and 250 µL LiteTouch™ System (LTS) tip configurations, these empty racks serve as the rigid structural foundation for Green-Pak® and SpaceSaver™ nested tip plates. Injection-molded from premium, heavy-gauge virgin polypropylene, these highly resilient housings are built to withstand repetitive autoclave sterilization cycles, allowing laboratories to drastically minimize solid plastic waste profiles.

Technical Performance & Design

• LTS-Compliant Deck Stabilization: Precision-molded internal deck geometry secures 200 µL / 250 µL LTS tip plates firmly in place, neutralizing vertical deflection and ensuring a reliable mechanical seal under multichannel tip-loading forces.
• Hinged-to-Lift-Off Adaptable Cover: Outfitted with an adaptable transparent lid that functions as a standard swinging hinge or can be completely detached to accommodate tight bench spaces, laminar flow hoods, or automated liquid handler enclosures.
• Autoclave Thermal Resilience: The high-density polymer composition is thermally rated to endure standard autoclave sterilization loops at 121°C (15 psi for 15–20 minutes) without warping, cracking, or dimensional distortion.
• Secure Mechanical Front Latch: Equipped with a snap-locking front clasp that prevents accidental opening during transit across facility zones while remaining easy to open with a single hand 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 biological safety cabinets.
• 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.
