Chemistry controls & system consumables
Reagents are only part of the recurring supply for a chemistry platform. Controls, calibrators, reaction cuvettes, wash liquids and cleaners each have their own compatibility and pack requirements. This group helps keep them visible in a quote. Use the exact analyser and approved product references, and distinguish a routine reorder from any proposed change to the laboratory’s quality materials or system-care products.
Useful details for your quote
- Analyser manufacturer and complete model
- Required analytes and quality-material levels
- Control or calibration role
- Cuvette and system-liquid references
- Pack contents, volumes and quantities
- Expiry and labelled in-use stability
Separate QC from calibration
A control is not automatically a calibrator. Identify the intended role and exact product, then ask for analyte coverage and applicable assigned values. A multi-analyte label may sound comprehensive while omitting an assay on the laboratory’s menu. Review the offered material against the actual required list.
Check method-specific values
Assigned values can depend on the method or platform. Request the relevant lot documentation rather than relying only on a brochure. If the laboratory plans a change of quality material, keep the alternative visible for its internal review and avoid combining it with a routine exact-reference reorder.
Identify the reaction format
Disposable and reusable cuvettes create different supply and care requirements. Give the analyser’s required cuvette reference, dimensions or format. A generic optical cuvette should not be assumed to fit an automated reaction system, even when both are described as chemistry consumables.
Name system liquids precisely
Wash, rinse and cleaning products can have distinct functions. Copy the approved names and references accurately, including any concentrated format. The instrument’s instructions determine permitted system-care use; procurement should not infer interchangeability from similar chemical names or generic laboratory-grade descriptions.
Plan the complete replenishment
List each product with quantity and usable-life requirement. Ask which supplies are included in a reagent or equipment package and which require separate orders. This prevents an apparently complete assay purchase from arriving without the compatible quality material or system consumable needed by the laboratory.
Common questions
Does a multi-analyte control cover every chemistry assay?
Not necessarily. Check the specific analyte list and applicable values for your methods and platform.
Are cuvettes universal?
No. Specify the instrument’s required reaction format and reference, especially for automated systems.
Can system cleaner be included in the reagent quote?
Yes, as a separately identified line with the correct reference, format and quantity. This keeps recurring requirements easy to check.
