NW2833 Scientific Services Capex Framework

Tender description

Northumbrian Water Limited wish to purchase some major items of analytical laboratory equipment over the next 5 years. The incumbent suppliers are Agilent Technologies, & Skalar. They were awarded a framework contract in 2021. Using information from the AMP8 capex replacement programme, prices will be sought up front, and a strategic partner or partners would be awarded a five year framework. The framework will be split into five lots as follows: 1. Gas Chromatography / Mass Spectrometry (GCMS) 2. Liquid Chromatography / Mass Spectrometry (LCMS) 3. Inductively coupled plasma / Mass Spectrometry (ICP MS & OES) 4. Flowcytometry 5. Ancillary laboratory equipment Lot 1: Gas Chromatography / Mass Spectrometry (GCMS) • Systems are currently used for drinking water (DW) analysis of final and raw waters for a range of herbicides and pesticides. • Used for semi-quant analysis to identify SV unknowns • Need library for ID • Hydrogen (He alternative) to be used as carrier gas • Autosampler capacity ca 50 place • Chromatographic integration software Lot 2: Liquid Chromatography / Mass Spectrometry (LCMS) • Systems are currently used for drinking water (DW) analysis of final and surface waters for a range of herbicides and pesticides. • First system will need to achieve limits of quantification (LoQ) calculated as defined by Drinking Water Inspectorate (DWI) regulations similar to existing for urons or as a minimum better than LoQ of 30% of PCV by either direct injection or via use of incorporated online enrichment for potable and surface water samples using a maximum sample volume of 5ml. Use triple quadruple technology. • Second system (yr 3) is for the analysis of pesticides with same performance requirements as above • Include automated online pre-concentration which is able to process up to 5ml sample • Autosampler capacity ca 100 place • Chromatographic integration software capable of CSV or similar format output Lot 3: Inductively coupled plasma / Mass Spectrometry (ICP MS & OES) • System capable of achieving drinking water (DW) analysis as defined by Drinking Water Inspectorate (DWI) regulations of final and surface waters for a range of metals including: Cr, Ni, Ag, Cu, Zn, Pb, Cd & Hg. • Achieve limits of quantification calculated as defined by Drinking Water Inspectorate (DWI) regulations similar to existing methods or as a minimum better than LoQ of 30% of PCV • Autosampler capacity ca 150 place • software capable of CSV or similar format output Lot 4: Flowcytometry • Flow cytometer benchtop cell-analysers capable of fast flow rates. • Able to auto sample from 96 well plates or equivalent. • Must feature acoustic hydrodynamic focussing. • Equipped with a minimum of one laser at wavelength 488nm. • Fluorescence resolution performance capability of CV Lot 5: Ancillary laboratory equipment MICROBIOLOGY INCUBATORS Required for the controlled incubation of microbiology culture samples. AUTOCLAVES • Temp range up to 135.0°C, typically operate at 121.0°C. BOILING BATHS • Must be able to maintain a rolling boil. • Safety features such as long handles and lids are critical. • Typical volume - 30L. • Easy drainage to clean. GLASSWASHERS • Laboratory grade e.g. Miele. Domestic dishwashers are unsuitable. • Must be able to run a 60°C cycle for taste and odour glassware. • Requirement to accept an external deionised water feed may be required for a final rinse stage. • Ideally will have a Manufacturer's option of being raised for ergonomic loading and unloading. 47MM MAGNETIC FILTERS FUNNELS • Fully compatible with Cytiva (formally Pall) manifold system. • Magnetic Seal to allow easy, one-handed vacuum filtration of liquids. • 7.6cm diameter. • Polyphenylsulfone construction. • Graduated 50mL increments. • Nonsterile. • Fully Autoclavable. • #8 stopper with proper bore hole size included. • Approximately 10 per annum 150mL funnel capacity (Cytiva 4247 or equivalent). • Approximately 5 per annum 300mL funnel capacity (Cytiva 4242 or equivalent). LABORATORY FRIDGE & FREEZERS • Laboratory grade. OVENS • Laboratory grade.
