PolyScience SD07R-20-A11B Space Saving Refrigerated Circulator 7L 120V

Description

Product Overview

The PolyScience SD07R-20-A11B is a space‑saving refrigerated circulator engineered for laboratory environments where precision, reliability, and compact footprint are essential. With a 7 L bath capacity, the unit delivers temperature control ranging from -20 °C to 170 °C, covering the full spectrum of heating and cooling applications required in chemistry, biology, and materials science. The circulator features a robust Duratop chemical‑resistant deck that withstands aggressive solvents and acids, ensuring long‑term durability and easy maintenance. The integrated digital temperature controller provides an intuitive interface with large, easy‑to‑read displays, and the swivel 180° rotating controller allows users to position the control panel for optimal ergonomics. Power requirements are 120 V/60 Hz, making the device compatible with standard North American laboratory power supplies. The compact dimensions and lightweight design (approximately 0.16 oz) enable placement on crowded benchtops without sacrificing performance.

Usage

This circulating bath excels in a variety of laboratory settings, from routine sample incubation to advanced thermal cycling protocols. Researchers conducting enzyme kinetics, cell culture, or polymer synthesis can rely on the rapid temperature ramp rates and tight stability to maintain experimental conditions within ±0.1 °C. The unit’s large bath opening simplifies the insertion and removal of containers, beakers, flasks, or custom reactors, while the lid dock stowing system keeps the workspace tidy and reduces contamination risk. Its chemical‑resistant deck is particularly advantageous for experiments involving corrosive reagents, as the surface can be cleaned with standard laboratory solvents without damage. The circulator is also suitable for educational labs, where students benefit from the clear digital readout and the ability to quickly switch between heating and cooling modes. Its quiet operation and low vibration profile make it compatible with sensitive analytical instruments such as spectrophotometers and microscopes.
