CEFAS25-138 Supply of a High-Precision Microbalance

Tender description

Cefas require the supply of a high-precision microbalance for its Weymouth Laboratory. Accurate weighing of various chemicals is essential to support our experimental work. The Cefas Chemicals Programme, primarily funded by Defra, undertakes research, testing, and advisory activities to support UK chemical risk assessment and regulatory obligations. The programme underpins national commitments regarding chemical safety, endocrine disruption, and environmental protection, with a focus on the development of test guidelines, endocrine disruption studies, ecotoxicology, and the advancement of new approach methodologies that aim to minimise animal testing. Accurate weighing of various chemicals is essential to support our experimental work. Currently, the laboratory houses a microbalance that was acquired over 15 years ago and is now discontinued. Securing a suitable replacement has become a priority to ensure continuity of operations. This RFQ seeks proposals for the supply of a high-precision microbalance that meets the specifications outlined below. The new equipment will enable Cefas to continue delivering robust scientific outputs while supporting sustainability and operational efficiency. Scope of Requirements: 1. Technical Requirement The microbalance must meet the following requirements: • Draft shield: Automatic preferred (manual acceptable if necessary), • Maximum capacity: 120g • Readability: o Fine range: minimum 0.002 mg o Coarse range: minimum 0.005 mg • Repeatability: o Fine range: minimum 0.005 mg o Coarse Range: minimum 0.01 mg • Capacity to sustain small vibration (due to proximity to a fume hood) • Dimensions: The equipment must not exceed 52 cm in length, 30 cm in width, and 24.5 cm in height. • Compliance with UK/EU safety standards for laboratory equipment. 2. Environmental Considerations • Unit should have an ultralow power consumption. • Supplier to manage packaging responsibly, ensuring reuse or recycling wherever possible. If packaging removal is not included, provide clear guidance on environmentally friendly disposal options. 3. Installation • Comprehensive installation and setup instructions • Any calibration requirements and guidance • Details of tools or accessories needed for installation • Safety considerations for handling and positioning the equipment 4. Ease of maintenance • Clear guidance on routine maintenance and calibration procedures • A technical support contact when required 5.
