Build a complete laboratory equipment list: compare model variants, accessories, utilities, consumables and quotation scope before ordering BIOBASE or Infitek instruments.
Scientific & laboratory RFQ checklist (TXT)
A useful laboratory quotation starts with the work the equipment must perform. A list that says only ‘centrifuge, freezer and incubator’ leaves the rotor, storage capacity, operating conditions and installation scope unresolved. VVON's BIOBASE catalogue and Infitek catalogue let you search by model and equipment category, then bring the selected items into one enquiry.
Compare exact models against the same method, capacity, sample type and installation brief. Neither brand name alone establishes suitability. Start with the BIOBASE catalogue and Infitek catalogue, then compare the included accessories, consumables, documents and support scope.
Cabinet class and type, working width, options, delivery and the installation and testing scope affect the comparison. Have the responsible laboratory team define the containment and room requirements first; a wider cabinet or a different type is not automatically a better fit. Browse the biosafety cabinet models and request a dated quotation for the exact configuration.
Yes. Add the instruments to one enquiry list and include quantities, application, model variants and accessories. Ask for separate lines for equipment, consumables, delivery, installation, training and any qualification work. This makes omissions easier to spot when comparing offers.
For sample drying, use the freeze-dryer and lyophiliser buying guide to define chamber format, sample chemistry, batch load and pump requirements. For controlled corrosion testing, use the salt-spray chamber guide to define specimens, the test method and site utilities. Keep these requirements as named lines in the overall laboratory schedule.
Record the sample types, preparation steps, tests, daily workload and storage needs. Separate equipment needed for each workstation from shared instruments. Include the peak workload and cleaning or changeover time; the number of samples arriving on an average day may not describe the busiest period. For a teaching laboratory, add the number of students working together and the practical exercises to complete.
| Equipment family | Information to include in the enquiry |
|---|---|
| Centrifuges | Tube dimensions, sample count, required RCF, rotor, adapters and temperature needs |
| Refrigerators and freezers | Sample type, usable storage volume, temperature range, racks, alarms and monitoring |
| Incubators and chambers | Working volume, temperature, atmosphere, humidity or agitation required by the method |
| Cabinets and extraction | Process, risk assessment, working width, airflow or exhaust requirements and room layout |
| Analytical instruments | Sample matrix, method, range, detectors, software and reporting needs |
| Autoclaves and washers | Load type, chamber capacity, cycle requirements, utilities and required documentation |
Manufacturer family pages may contain several models. Read the column for the model you intend to buy: capacities, dimensions and electrical requirements can differ within one family. Do not combine one model's capacity with another model's speed or temperature range. The linked VVON product pages preserve the published specification tables so variants can be checked together.
For laboratory centrifuges, identify the rotor and tube adapters as separate quotation lines. For refrigerators and freezers, specify usable storage, racks and monitoring. For PCR and nucleic-acid equipment, record the reaction format, throughput, consumables and software needed by the proposed workflow.
Provide a room drawing where installation matters. Check delivery access, bench dimensions, equipment weight and working clearances against the selected model. Identify power, water, drains, ventilation, gases, cooling and environmental conditions in the manufacturer's installation information. Assign responsibility for any enabling work, rather than assuming it is included in equipment delivery.
Cabinets need particular attention to the intended process. Compare biosafety cabinets, laminar-flow equipment and fume hoods against the laboratory's assessed requirements. Similar appearance or working width does not establish that two cabinet types provide the same protection.
There is no single meaningful price for a broad instrument family. Ask suppliers to quote the same configuration and clearly identify omissions. A lower base-instrument price may exclude accessories required by your method. Current availability and delivery also need confirmation; inclusion in an online catalogue does not establish local stock.
Use the product cards to add selected items to your enquiry list. Include model variants, quantities, delivery location and the required date. If you do not yet have a shortlist, send VVON the workflow and equipment requirements. Clinical analyser and pathology purchases have a separate clinical laboratory procurement checklist.
Ranges and product specifications can be checked against the BIOBASE manufacturer catalogue and Infitek manufacturer catalogue. Each VVON product page links to its manufacturer source. Catalogue review: 28 September 2026; confirm the latest configuration in the quotation.
