Manual bottleneck distributor

Targeted Precision Dispensing Solution for Laboratory Applications

The Manual Bottleneck Distributor is engineered to meet the precise liquid handling needs of laboratory professionals, chemical analysts, and research institutions. Supporting workflows that often integrate with devices such as a laboratory centrifuge or low speed centrifuge, this instrument ensures accurate volume transfer while maintaining operational efficiency. It addresses the demands of controlled fluid dosing directly from reagent bottles, facilitating repeatable processes for users who prioritize rigor and compliance. Its ergonomic design complements bench centrifuge workflows by minimizing manual fatigue and streamlining sample preparation stages.

Critical Technical Specifications and Material Integrity

Constructed from chemically inert materials including PTFE, FEP, BSG, and PP, the distributor ensures resistance to aggressive reagents and supports full autoclavability at 121°C for liquid-contact parts. Volume ranges from 0.5 mL to 50 mL are precisely adjustable with systematic and random error margins of ±0.5% and ±0.2%, respectively, offering compliance with ISO 8655 standards. The availability of multiple adapters compatible with common reagent bottle neck sizes (S40, GL32, GL38, GL25, GL28) enhances system integration and flexibility. This design aligns well with the rigorous demands of processes involving laboratory centrifuge suppliers looking for precise pre- or post-centrifugation liquid handling tools.

Enhancing Laboratory Workflows Across Diverse Industries

This distributor is valuable in pharmaceutical, biotech, environmental, food quality control, and analytical testing settings where operation depends on accurate fluid transfer. It supports workflows including sample preparation before low speed centrifuge processing, titration assays, and reagent filling during experimental procedures. Its precision dosing facilitates methodological consistency and reproducibility, serving laboratories that demand reliability alongside equipment such as bench centrifuges. The option to incorporate this tool in training environments further supports educational institutions and quality assurance labs focused on liquid handling proficiency.

Product Advantages

Optimized Design for Chemical Resistance and Modular Use

The Manual Bottleneck Distributor features a structurally sound design with modular adaptability, incorporating chemically resistant PTFE, FEP, BSG, and PP materials that assure long-term durability within laboratory environments. Its liquid contact parts are autoclavable at 121°C, enabling effective sterilization processes. It supports integration with widely used reagent bottle neck adapters, which provides compatibility when paired with equipment often found in facilities operating bench centrifuges or laboratory centrifuges. The ergonomic mechanism allows smooth, low-force operation, maintaining user comfort during extended dosing procedures and repetitive laboratory workflows.

Superior Accuracy and User-Centered Performance Benefits

This instrument delivers ISO 8655-compliant dosing accuracy with systematic error controlled within ±0.5%, essential for precision-dependent applications where liquid volume consistency is critical. The easy-to-adjust volume settings and simple disassembly for maintenance improve usability and operational efficiency, reducing downtime and enhancing workflow throughput. This makes it an ideal complement to laboratory centrifuge applications by providing dependable volume transfer that supports sample integrity. Its ergonomic design reduces user strain and facilitates integration into routine analytical and experimental procedures requiring meticulous reagent handling.
