Description
Integra GripTips 1250 Microliter Pipette Tips – Green Choice Reload Inserts, 96 Tips Per Insert, Non-Filtered, Non-Sterile (MPN: 4442)
The Integra Biosciences 4442 is a premium, environmentally friendly Green Choice reload packaging system containing high-performance GripTips pipette tips engineered for handheld volumes up to 1250 microliters. Designed to reduce laboratory plastic waste by utilizing reusable tip rack housings, each reload pack features 5 independent inserts loaded with 96 tips per deck (480 tips total per pack). These 102 mm extended-length tips feature Integra’s patented locking snap mechanism that clicks firmly onto electronic and mechanical pipettors, establishing a completely leak-proof physical seal. Formulated from premium virgin polypropylene, these non-filtered, non-sterile inserts provide excellent fluid delivery without structural tip wobble or accidental drops.
Technical Performance and Design
-
Patented GripTip Snap-On Connection: Engineered with a specialized positive locking mechanism that physically clips onto matching Integra tip fittings. This design establishes high lateral resistance, ensuring tips remain perfectly leveled and securely attached during aggressive side-well touch-offs.
-
Eco-Conscious Green Choice Refills: Developed explicitly as a low-waste alternative to single-use plastic racks. These loose tray inserts slide directly into existing empty Integra PopTop storage bases, dropping plastic packaging waste by more than 60 percent across the lab footprint.
-
Deep-Well 102 mm Reach Architecture: Features an elongated 102 mm total tip length profile. This slim outline gives the user access to the bottom quadrants of deep microplates, conical storage vials, and standard reagent reservoirs without risking direct pipette shaft friction contamination.
-
Certified Cleanroom Purity Claims: Produced inside automated high-purity cleanrooms in accordance with strict Viapure quality standards. Every batch is certified free of detectable RNase, DNase, human DNA, endotoxins, and pyrogenic inhibitors to secure target molecular evaluation metrics.

Key Benefits and Applications
-
Eliminated Tip Drops: The engineered interlocking shoulder design removes the need to hammer tips onto the pipette cone, eliminating accidental tip drop-off hazards mid-assay and stabilizing liquid delivery lines.
-
High-Precision Solution Aliquoting: Smooth interior walls reduce fluid retention anomalies, ensuring the precise transfer of large sample volumes, cell culture medias, and chemical buffers down to fractions of a microliter.
-
Multi-Channel Deck Alignment: The structural layout locks each of the 96 tips perfectly upright and flat, allowing multi-tip pipettors to grab full rows at once with minimal mechanical effort.
-
Autoclave Bench Preparation: Polypropylene material properties safely withstand routine high-temperature steam sterilization parameters (121 C) once the inserts are nested inside reusable base racks.
