Analytical is pleased to offer the new Temperature Controlled Reactors (TCRs). The TCR is a 24 or 48-position fluid-filled reactor that keeps temperature consistent throughout the block and around your samples. It greatly reduces excessive heat that can be caused by external sources, such as a Lumidox®II solid base LED array. Any fluid within the specified range can be pumped through the reactor to maintain well-to-well temperature uniformity.

Sample-to-sample thermal uniformity can be difficult to achieve with high-throughput chemistry. Extreme temperature differences, thermal inconsistency, and thermal overload can all impact experimental validity, especially when using techniques like photocatalysis. The TCR solves these issues.

Standard 96 or 24-position reactor blocks have no internal fluid path and no way to accurately set and control temperature uniformity. As such, high-powered LEDs used for photocatalysis reactions can produce an overall reactor heat gradient of up to +/- 13°C, with severe heat island effects. Analytical’s TCRs are capable of controlling temperatures to a uniformity of +/- 1°C. Compatibility is one of the most important parameters of the TCR design. Internal testing ensured that the Temperature Controlled Reactor is fully compatible with all accessories provided by Analytical.

  • Provides users with options to screen either 24 individual 1-DRAM vials (13mm, 15 x 45mm, 4mL) or 48 individual microvials (8 x 30mm) at near-equal temperatures
  • Provides extremely uniform thermal control for high throughput experimentation (HTE) with a temperature difference of +/- 1°C. To achieve the performance specifications of the TCR system, the use of a Lumidox®II TCR 48 LED, or 24-18 LED array is required.
  • Capable of enhanced re-producibility in heating and cooling applications
  • High quality, leak-proof CPC fittings for quick and easy tubing connection
  • Compatible with a wide range of heat-transfer fluids such as: water (down to 5°C), silicone-based fluids (ie SYLTHERMTM™), ethylene glycol, and polypropylene glycol
  • Designed to standard SLAS dimensions (127.75mm x 85.5mm) with standard 9mm (48-position) or 18mm (24-position) well-to-well pitch
  • Compatible with auto-samplers and other staples of high throughput chemistry
  • 4mm holes in lid allow for use with most common auto sampler needles
  • Threaded holes (6-32) in lid for accessory attachment
  • 3.2mm diameter port accommodates standard 3mm thermocouple or cryostat probes for remote temperature measurement
  • Each TCR unit undergoes a gas-tight and watertight evaluation before they are released
