MTC Bio Exact Volume Transfer Pipette E9500-20 | 20µL, 53mm, Sterile — 5,000/Case (10 Resealable Bags of 500)

Product Description

The MTC Bio Exact Volume Transfer Pipette E9500-20 is a 20µL 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 20µL is dispensed every time. Manufactured from chemically resistant LDPE. Sterile packaging — an MTC Bio exclusive. 53mm length. 5,000 pipettes per case — 10 resealable bags of 500. Catalog # E9500-20.

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 20µL and no more is released from the stem tip

This dual-bulb system produces consistent, repeatable 20µL deliveries regardless of operator technique — making the E9500-20 suitable for applications where single-bulb transfer pipettes produce unacceptable volume variability.

20µL — The Smallest Volume in the Exact Volume Transfer Pipette Family The E9500-20 delivers exactly 20µL per dispense — the smallest volume in the MTC Bio Exact Volume Transfer Pipette lineup. At 20µL, the E9500-20 covers the volume range of standard PCR and qPCR reactions, microscopy staining volumes, small-scale reagent additions, and molecular biology applications where 20µL is the standard working volume. For labs working with expensive reagents, rare samples, or sensitive assays where consistent 20µL delivery is required but a calibrated pipette is unavailable or impractical, the E9500-20 provides a single-use sterile alternative that eliminates carry-over contamination and calibration maintenance concerns.

Sterile Packaging — An MTC Bio Exclusive Sterile packaging — an MTC Bio exclusive. The E9500-20 is supplied sterile in resealable bags — a distinctive feature that sets the MTC Bio Exact Volume Transfer Pipette apart from standard non-sterile transfer pipettes. The sterile format qualifies the E9500-20 for use in cell culture, sterile media preparation, aseptic sample handling, and any application requiring a sterile liquid handling consumable at 20µL volume. The 10-bag resealable packaging format maintains the sterility of unused pipettes after the bag is opened — a practical advantage for labs that use small numbers of pipettes at a time throughout the day.

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, most acids and bases at standard laboratory concentrations, alcohols, and a wide range of molecular biology reagents. The LDPE material is flexible enough for comfortable pinch-and-release operation while maintaining the structural integrity required for consistent volume delivery.

Minimal Liquid Retention — Maximum Sample Recovery Minimal liquid retention. The LDPE material and tip geometry of the E9500-20 minimize the volume of liquid retained on the inner surfaces of the stem after dispensing — ensuring that the full 20µL is delivered to the target vessel rather than being lost to tip wetting. For applications involving expensive or rare reagents where every microliter matters, minimal liquid retention is a critical performance requirement.

Designed for Routine Lab Workflows and Kit-Based Use Engineered for clean release and dependable performance, they are ideal for routine lab workflows, molecular applications, and kit-based use where simplicity and reliability matter most. The E9500-20 is specifically designed as a kit-bundled or workflow-embedded consumable — providing a reliable single-use sterile 20µL delivery tool that can be included in diagnostic kits, molecular biology assay kits, and standardized laboratory protocols where consistent volume delivery is required without access to or maintenance of calibrated pipette systems.

Compatible Replacement — Cross-Reference Guide

The MTC Bio Exact Volume Transfer Pipette E9500-20 is a comparable alternative to sterile transfer pipettes from several major manufacturers:

• Samco™ Transfer Pipettes — standard sterile transfer pipettes, 20µL 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 E9500-20 uniquely provides exact volume delivery through its dual-bulb design — differentiating it from standard single-bulb transfer pipettes that rely on operator technique for volume consistency. These products may differ in volume accuracy and performance characteristics.
