MTC Bio Exact Volume Transfer Pipette E9500-80 | 80µL, 96mm, Sterile — 2,500/Case (5 Resealable Bags of 500)

Product Description

The MTC Bio Exact Volume Transfer Pipette E9500-80 is an 80µL sterile LDPE dual-bulb transfer pipette — engineered for consistent, repeatable liquid handling without the complexity of calibrated instruments. The unique dual-bulb design features an upper pinch bulb for standard pipetting via familiar pinch and release action, and a lower overdraw bulb that captures excess liquid — trapping the extra sample in the overdraw bulb during release and ensuring that only the exact desired volume of 80µL is dispensed every time. Manufactured from chemically resistant LDPE. Sterile packaging — an MTC Bio exclusive. 96mm length. 2,500 pipettes per case — 5 resealable bags of 500. Catalog # E9500-80.

The Dual-Bulb Design — The Defining Innovation of the Exact Volume Transfer Pipette Standard single-bulb transfer pipettes rely on the user's manual technique to dispense a consistent volume — an inherently imprecise approach that produces variable results between operators and between draws. The MTC Bio Exact Volume Transfer Pipette eliminates this variability through its patented dual-bulb system:

• Upper pinch bulb — the primary working bulb, compressed by the user to aspirate and dispense liquid using the familiar pinch-and-release action of a standard transfer pipette
• Lower overdraw bulb — a secondary bulb positioned between the upper bulb and the stem, designed to capture any liquid drawn in excess of the calibrated volume during aspiration. When the upper bulb is released, the excess liquid drawn into the overdraw bulb is retained there rather than being dispensed — ensuring that exactly 80µL and no more is released from the stem tip

This dual-bulb system produces consistent, repeatable 80µL deliveries regardless of operator technique — making the E9500-80 suitable for applications where single-bulb transfer pipettes produce unacceptable volume variability.

80µL — A Distinctive Mid-Volume for Enzyme Assays and Specialized Protocols The E9500-80 delivers exactly 80µL per dispense — a volume that fills an important niche between the standard 50µL and 100µL formats. At 80µL, the E9500-80 covers enzyme activity assays, specialized immunoassay protocols, nucleic acid quantification workflows, and any laboratory protocol specifically optimized at 80µL scale. For labs working with assay kits and standardized protocols that specify 80µL volumes — where a standard 50µL pipette would underfill and a 100µL pipette would overfill — the E9500-80 provides the precisely correct sterile delivery tool.

E9500-80 vs. E9500-50 vs. E9500-100 — The Small-Volume Range:

Note: The E9500-80 at 96mm is actually the longest of the three — longer than the 100µL E9500-100 at 86mm — providing extra reach for deeper vessels at this volume.

96mm Length — Extended Reach for Deeper Vessel Formats At 96mm total length, the E9500-80 is the longest of the small-volume pipettes in the E9500 family — providing extended reach for deeper tubes, vessels, and microcentrifuge tubes used in enzyme assay and specialized protocol workflows at 80µL scale. The 96mm length accommodates reach into standard 15mL conical tube shoulders, deep microcentrifuge tubes, and other vessels where shorter transfer pipettes cannot reach the working volume at the bottom.

Sterile Packaging — An MTC Bio Exclusive Sterile packaging — an MTC Bio exclusive. The E9500-80 is supplied sterile in resealable bags — qualifying it for cell culture, sterile media preparation, aseptic sample handling, and any application requiring a sterile liquid handling consumable at 80µL volume. The 5-bag resealable packaging format maintains the sterility of unused pipettes after the bag is opened.

Chemically Resistant LDPE — Compatible with a Wide Range of Solutions Manufactured from chemically resistant LDPE. Low-density polyethylene (LDPE) provides broad chemical compatibility — suitable for aqueous buffers, saline solutions, culture media, enzyme substrates, most acids and bases at standard laboratory concentrations, alcohols, and a wide range of molecular biology and biochemistry reagents commonly used in enzyme assays and specialized protocols.

Minimal Liquid Retention — Maximum Sample Recovery Minimal liquid retention. The LDPE material and tip geometry of the E9500-80 minimize the volume of liquid retained on the inner surfaces of the stem after dispensing — ensuring that the full 80µL is delivered to the target vessel.

Compatible Replacement — Cross-Reference Guide

The MTC Bio Exact Volume Transfer Pipette E9500-80 is a comparable alternative to sterile transfer pipettes from several major manufacturers:

• Samco™ Transfer Pipettes — standard sterile transfer pipettes, 80µL approximate volume
• Globe Scientific Transfer Pipettes — sterile LDPE transfer pipettes, small volume range
• Thermo Fisher Fisherbrand™ Transfer Pipettes — sterile transfer pipettes, small volume range
• Alpha Laboratories Disposable Pasteur Pipettes — sterile LDPE transfer pipettes

The E9500-80 uniquely provides exact 80µL volume delivery through its dual-bulb design — differentiating it from standard single-bulb transfer pipettes that rely on operator technique for volume consistency.
