PR1MA™ Disposable Spreaders

Sterile Disposable Bacteriological Spreaders – L-Shape, T-Shape, and Triangle.

PR1MA™ sterile disposable bacteriological spreaders are designed for efficient and safe sample spreading across agar plates. Available in four distinct shapes—L-shape, T-shape, and two triangle variants (30 mm and 60 mm)—these spreaders are ideal for a wide range of microbiological applications, including CFU counts, sample plating, and liquid dispersion.

Each spreader is manufactured with smooth, rounded edges to prevent cutting or gouging of the agar surface during inoculation. Supplied in sterile packaging, they ensure reliable and contamination-free performance in clinical, research, industrial, and educational laboratories.

L-Shape Spreaders (ABS Plastic)

• Slight upward curve minimizes surface dragging
• Excellent for general microbial culture applications 

T-Shape Spreaders (ABS Plastic)

• 34 mm spreading surface allows even pressure distribution
• Commonly used for CFU plate counts in water, milk, urine, and similar samples
• Designed for uniform liquid dispersion across agar plates

Triangle Spreaders (Polypropylene – 30 mm & 60 mm options)

• Grooved handle offers enhanced grip and orientation control
• Available in two sizes for greater versatility
• Ideal for colony-forming unit (CFU) analysis and spreading applications requiring precision

Key Features

• Smooth, rounded edges to prevent agar damage
• Individually sterile packaged for contamination-free use

PR1MA™ Disposable Inoculating Loops and Needles

Polypropylene & Polystyrene.

Our sterile disposable inoculating loops and needles are essential tools for accurate microbial sampling and inoculation in clinical, research, and industrial laboratories. Designed for single-use, they eliminate the risk of cross-contamination and remove the need for flaming or sterilization, improving workflow efficiency and safety.

Ideal for quantitative procedures such as urine counts, serial dilutions, and bacterial inoculation, these loops and needles are available in both flexible polypropylene and rigid polystyrene to suit a variety of microbiological applications.

The ergonomic hexagonal shaft design ensures improved grip, orientation, and control during streaking procedures. Each loop features smooth surfaces without burrs or rough edges, reducing the risk of cutting or damaging the agar surface during use.

Flexible Polypropylene Loops

• Excellent for maneuvering in Petri dishes, test tubes, and other tight spaces
• Gentle on delicate microbial colonies
• Allows for precise sample collection and transfer 

Rigid Polystyrene Loops & Needles

• Ideal for precise streaking and isolation of colonies
• Suitable for dense or viscous samples
• Provides better control during quantitative assays

Key Features

• Sterile and single-use – no risk of contamination, no flaming needed
• Available in loop and needle formats
• Hexagonal shaft for improved handling and control
• Smooth loop surfaces to prevent agar damage
• Available in flexible (polypropylene) and rigid (polystyrene) materials 

These inoculating tools are perfect for laboratories looking for consistent, contamination-free performance in microbial handling and culturing.

PR1MA™ Disposable Transfer Pipettes

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.
