When used with instrument configurations that include a Peltier-controlled cell holder, such as the DU 800 spectrophotometer, it actively heats or cools the sample to maintain stable temperatures during measurements. The standard controller supports temperature programming across a broad input range (10°C to 90°C), while the practical operating range for the cell-holder assembly is 20°C to 40°C, enabling measurements from near room temperature up to elevated temperatures. Related part numbers include 270-455863 and 517234, reflecting its role as a dedicated temperature-control module within Beckman Coulter’s optical workflow. Designed as a standalone controller, it integrates with Beckman Coulter instrument control interfaces to automate temperature ramps and setpoint holds during spectral scans, providing consistent baseline stability and repeatability for kinetic studies and temperature-sensitive assays.\u003c\/p\u003e\u003c\/div\u003e","brand":"Beckman","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676818243886,"sku":null,"price":95.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_37f47e1c-40a1-40f0-81af-4128ede514ad.jpg?v=1769553845","url":"https:\/\/plgautomation.com\/products\/beckman-coulter-lr34862-temperature-controller","provider":"PLG Automation ","version":"1.0","type":"link"}
