The Mini Pipette Fixed Volume Pipette from DLAB is a compact, single-channel mechanical pipette pre-set to a specific, non-adjustable volume for rapid, high-precision repetitive liquid handling. Featuring an ultra-light, one-piece molded body (~130 mm in length), it reduces user fatigue during high-throughput workflows. Integrated color-coding allows for immediate visual identification of the fixed volume (e.g., blue for 100 µL, orange for 50 µL), dramatically reducing selection errors in busy laboratories.

The pipette is fully autoclavable, ensuring sterility for aseptic cell culture and microbiology applications. Its universal tip cone is compatible with standard 200 μL and 300 μL tips. Each Mini Pipette is individually tested and supplied with an ISO 8655 calibration certificate, guaranteeing high precision and accuracy for standardized protocols.

For the medical laboratory technician, the fixed-volume design eliminates operator error and delivers fast, reproducible results for high-volume tasks like ELISA plate coating, PCR master mix preparation, and standardized sample inoculation for AST. For the patient, this reproducible sample handling ensures that diagnostic results for infectious diseases, antimicrobial susceptibility, and clinical chemistry are consistent, accurate, and reported with minimal turnaround time, directly supporting timely and effective therapeutic decisions.

Description

Mini Pipette Fixed Volume Pipette

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Rapid Bulk Reagent Dispensing for High-Throughput Assays

Primary Use: Provides a single-channel, spring-loaded mechanical pipette pre-set to a fixed volume, enabling rapid, consistent, and error-free dispensing of assay buffers, wash solutions, and bulk reagents for high-throughput ELISA and automated clinical chemistry platforms.
How it helps: For the medical laboratory technician, the fixed-volume design eliminates the risk of operator-induced volume changes, ensuring each well receives exactly the intended reagent volume, thereby improving inter-assay precision. The fast, one-step operation allows for rapid dispensing into large numbers of tubes or plates, dramatically increasing throughput. For the patient, precise, high-speed reagent dispensing reduces well-to-well variability in diagnostic tests like ELISA, leading to more accurate detection of autoantibodies or infectious disease markers.

2. Fixed-Volume Sample Transfer for Standardized Microbiology

Primary Use: Utilized for the precise, pre-determined delivery of bacterial suspensions, standardized inocula, and reagent volumes in antimicrobial susceptibility testing (AST) and colony counting procedures.
How it helps: For the clinical microbiologist, the pipette’s fixed volume delivers an exact amount of sample every time, which is critical for performing standardized Kirby-Bauer disk diffusion tests or preparing McFarland standards. This consistency allows for accurate comparison of results across different batches and laboratories. For the patient, standardized and reproducible sample inoculation ensures that antibiotic susceptibility results (SIR – Susceptible, Intermediate, Resistant) accurately guide appropriate antibiotic therapy, improving treatment outcomes and reducing the risk of antimicrobial resistance.

3. Consistent Media and Buffer Preparation in Cell Culture

Primary Use: Employed for the repeated, precise addition of culture media, trypsin, or dissociation reagents to multi-well plates, culture flasks, and microplates during routine cell culture and passaging procedures.
How it helps: For the cell culture scientist, the fixed-volume design ensures that each culture vessel receives the same volume of nutrient medium or reagent, promoting uniform, consistent cell growth across all vessels and eliminating one potential variable in the experiment. The fully autoclavable tip cone and durable construction make it suitable for aseptic work within a biosafety cabinet. For the patient, consistent cell culture conditions support accurate outcomes for cell-based diagnostic tests and therapies, such as viral load testing for HIV or CMV, or the safety of cell-based products.

4. Standardized Reagent Addition for Qualitative Rapid Tests

Primary Use: Used for the accurate addition of a fixed volume of sample or chase buffer to the sample well of lateral flow immunoassay devices (e.g., point-of-care test cassettes).
How it helps: For the laboratory technician, the single fixed-volume step simplifies the process for running large batches of qualitative rapid tests. The user simply draws up the sample and dispenses the entire pre-set volume into the test cassette, reducing the chance of technique-based errors and improving consistency across operators. For the patient, standardized sample volume ensures the test strip develops correctly, providing clear, accurate positive/negative calls for a wide range of rapid infectious disease tests.

5. Color-Coded Design for Rapid Volume Identification

Primary Use: Color-coded body markings (e.g., blue for 100 µL, orange for 50 µL, green for 10 µL) allow for immediate visual identification of the pipette’s fixed volume capacity, minimizing the risk of selecting the wrong pipette in a busy lab.
How it helps: For the laboratory manager, this intuitive visual system reduces the time technicians spend verifying pipettes and helps prevent the use of an incorrect volume in a critical step. The compact, lightweight design and small size (~130 mm in length) also make the pipette easy to handle, store, and sterilize. For the patient, this intuitive color-coding directly reduces the risk of pre-analytical volume errors, which can lead to a failed batch of patient tests and costly, time-consuming repeats.
