MULTIVAP Parts and Accessories List

Significance of the topic

The availability and correct specification of spare parts and accessories for sample evaporation and concentration systems is essential for maintaining reproducible workflows, minimizing downtime, and ensuring safety when handling volatile or corrosive solvents. A clear and accessible parts list supports laboratory quality assurance, inventory management, and proper selection of materials compatible with specific solvents and sample volumes.

Objectives and overview of the document

This document is a concise catalog of MULTIVAP parts and accessories. Its primary aims are to: provide part numbers and packaging details for routine consumables (needles, adapters, plugs), identify components for gas supply and filtration, and list custom inserts and racks for MULTIVAP instruments of various capacities. A note indicates that part numbers for acid‑resistant units require direct contact with the vendor.

Methodology and scope

The source is a supplier parts list organized as a table of items, brief descriptions, part numbers, and typical sales packaging (individual or sets). Visuals (pictures) accompany some entries. The catalog covers consumables, fluid/gas handling accessories, and modular rack/inset options for MULTIVAP systems with different sample capacities (9, 30, 48, 64, 100 positions).

Used instrumentation

• MULTIVAP sample concentration/evaporation systems (various position capacities: 9, 30, 48, 64, 100).
• Nitrogen gas generator (20 LPM) specified for up to 48 sample positions (part NA1955).
• Accessories for gas handling: connector tubing, paper‑filled air filter for N2/Z‑purge/air compressors, luer fittings and manifold components.

Main results and discussion

The parts list groups components into consumables for sample delivery, gas/fluid management, and modular fixtures for different MULTIVAP sizes. Key items and practical notes include:

• Needles: Stainless steel needles (304 grade, 4 in × 19 gauge) sold in sets (e.g., NA0603 for sets of 12) for general use; FEP‑coated needles of the same size are offered for corrosive solvents to reduce chemical attack and sample contamination.
• Adapters and flow control: Pasteur pipette adapter with flow controller (male luer to 1/8 hose barb) available in sets (e.g., NA1303 for 50 pieces) to couple common lab pipettes to tubing and manage solvent flow during processing.
• Luer fittings and plugs: Plastic luer plugs for unused fittings (NA1307) and luer/washer assemblies (P1306) for the MULTIVAP manifold help maintain system integrity and prevent leaks or contamination.
• Gas supply accessories: Connector tubing (6 ft coiled polyurethane, NA1101) and a paper‑filled air filter for N2 or compressor supply (NA0403) are listed; these support clean, dry inert gas delivery and protect the instrument from particulates.
• Fasteners: Hoist thumb screw (P0612‑N) included as a replacement mechanical accessory.
• Nitrogen generation: A 20 LPM nitrogen generator (NA1955) is specified for systems supporting up to 48 sample positions, permitting on‑site inert gas supply and reduced dependence on gas cylinders.
• Custom inserts and racks: Numerous items allow configuration for different sample counts—custom inserts for 9, 30, and 48 position MULTIVAPs (NA1891, NA1831/NA1832, NA1801/NA1803) and custom racks for 64 and 100 position systems (NA1360, NA1361). These are sold individually or in sets depending on system capacity.

The catalog makes clear whether items are sold individually or in predefined sets (12, 30, 48, 50, etc.), which is important for procurement planning. The document also flags that acid‑resistant unit part numbers are handled separately, signalling material compatibility considerations for aggressive chemistries.

Benefits and practical applications of the parts list

• Operational continuity: Quick identification of part numbers enables fast replacement of wear items and reduces instrument downtime.
• Solvent compatibility: Availability of FEP‑coated needles and a note on acid‑resistant units helps labs choose components suitable for corrosive solvents and extend service life.
• Scalability and customization: A range of inserts and racks allows adaptation of MULTIVAP instruments to varying sample throughput requirements, from small batches to high‑throughput configurations.
• Gas management: Integrated options for tubing, filtration, and an on‑site nitrogen generator support reliable inerting and evaporation performance without reliance on cylinder logistics.
• Inventory and procurement: Clear packaging and part number information supports ordering efficiency and stock control in QA/QC and research laboratories.

Future trends and possible applications

• Material innovations: Increased use of advanced corrosion‑resistant polymers and metal alloys for consumables to broaden compatibility with aggressive solvents and extend service intervals.
• Modular automation: Greater integration of custom racks and inserts into automated sample handling workflows, improving throughput and traceability.
• On‑site gas solutions: Wider adoption of compact nitrogen generators with flow modulation for larger position counts to reduce operating costs and safety concerns associated with gas cylinders.
• Digital inventory and traceability: Embedding RFID or barcode identifiers on consumable kits and racks to streamline procurement, maintenance scheduling, and regulatory compliance.
• Vendor customization services: Continued growth in custom insert/rack manufacturing to meet nonstandard tube formats and specialized sample containers used in diverse analytical workflows.

Conclusion

The MULTIVAP parts and accessories list provides a practical, concise reference for consumables, gas handling components, and modular fixtures needed to operate and maintain sample evaporation systems. Clear part numbering, packaging information, and attention to solvent compatibility make it a useful tool for purchasing and laboratory maintenance planning. For acid‑resistant components, direct vendor contact is required to obtain the appropriate part numbers.
