1 µL Inoculating Loops in Pakistan

1 µL Inoculating Loops (Microbiological Inoculation Loops) are precision-molded, disposable laboratory consumables engineered for quantitative microbial plating, colony picking, and streak plate isolation. Manufactured from flexible medical-grade polypropylene (PP) or polystyrene (PS), these loops deliver an accurate 1 µL sample volume without cutting or scratching agar surfaces. Essential for microbiology laboratories, clinical pathology diagnostic centers, water testing facilities, and academic research units across Pakistan.

1 µL Inoculating Loops – Quantitative Microbiological Grade

1 µL Inoculating Loops provide a sterile, ultra-consistent, and time-saving alternative to traditional wire metal loops in routine microbiological procedures. Precision-molded to eliminate surface burrs and irregularities, the smooth 1 µL loop head ensures uniform surface tension for accurate volumetric sampling of liquid cultures and urine specimens. Engineered with an ergonomic, flexible shaft, these loops allow smooth streaking across delicate agar plates without damaging or gouging the growth medium. Designed as single-use disposable labware, they eliminate the need for flame sterilization, reducing aerosol formation and cross-contamination risks in biological safety cabinets.

Key Applications:

Quantitative Urine Culture: Standard instrument used in clinical pathology labs across Pakistan for calibrated urine plating and bacterial colony counting ( $10^3$ to $10^5 \text{ CFU/mL}$ ).
Bacterial & Fungal Isolation: Ideal for streak-plating, single-colony picking, and transferring biological cultures onto nutrient agar.
Serial Dilutions & Inoculation: Applied in diagnostic microbiology and pharmaceutical quality control for precise micro-volume sampling.

Product Name: 1 µL Inoculating Loop / Calibrated Microbiological Loop
Calibrated Loop Volume: 1 µL ( $\pm 5\%$ volumetric accuracy)
Material Construction: High-clarity medical-grade Polypropylene (PP) or High-Impact Polystyrene (HIPS)
Dual-Function Options: Standard loop-and-needle design (1 µL loop at one end, fine inoculation needle at the opposite end)
Surface Quality: Smooth, polished loop geometry with burr-free surfaces to protect agar integrity
Shaft Flexibility: Semi-flexible shaft providing optimal tactile control during streaking
Thermal Properties: Heat-sensitive plasticware (Non-autoclavable; single-use disposable)
Sterility & Purity: Gamma-irradiated or EO sterile; certified free of DNase, RNase, and pyrogens
Packaging Options: Individually wrapped or zip-bagged in sterile sleeves of 10, 20, or 50 pieces
Storage Conditions: Store at ambient room temperature in a dry, clean area protected from direct heat sources and sunlight.

Safety & Handling:

Hazard Class: Non-hazardous plastic consumable prior to use. Biohazardous once contaminated with microbial cultures or clinical specimens.
Handling & Usage: Do not flame-sterilize plastic loops as they will melt and generate toxic fumes. Hold the shaft lightly and draw the loop flat against the agar surface to maintain smooth streaking mechanics.
Disposal: Single-use disposable laboratory plasticware. Autoclave used loops in biohazard waste bags or dispose of via accredited medical waste streams after use.
