PR1MA™ Disposable Transfer Pipets

LDPE, Disposable, RNase/DNase Free.

PR1MA™ Disposable Transfer Pipettes are made from ultra-clear, low-density polyethylene (LDPE), offering an unbreakable, one-piece design that eliminates the risk of broken glass, contaminated rubber bulbs, and exposure to infectious materials. These pipettes are ideal for a wide range of laboratory applications, including microbiology, blood banking, hematology, immunology, urinalysis, and tissue culture.

Available in 10 unique designs across 6 volume capacities, these pipettes provide options for every application—from general sample transfer to highly precise dispensing. Models with ultra-fine extended tips allow for accurate sample delivery into narrow vessels, microtubes, or 96-well plates.

Each pipette delivers uniform drop sizes, ideal for spotting gels, TLC plates, or dispensing into PCR tubes, ID strips, and microplates. LDPE’s low-affinity surface reduces loss of cells, proteins, or samples—critical for consistent and reliable results. Pipettes can also be heat-sealed for airtight sample storage.

Key Features

• Unbreakable, one-piece LDPE construction – eliminates glass breakage and contamination risks
• 10 pipette designs across 6 capacities for application-specific flexibility
• Available sterile (individually or in packs of 20), or non-sterile bulk
• Models with ultra-fine tips for precise dispensing into small or narrow containers
• Uniform drop size for reproducible applications (gels, TLC, microplates)
• Low sample retention surface – minimizes sample, protein, or cell loss
• Can be heat-sealed for secure sample storage
• Certified RNase-, DNase-, and pyrogen-free

Whether you're conducting routine lab procedures or high-precision assays, these sterile or non-sterile disposable transfer pipettes are a reliable choice for consistent sample handling.
