TPi series: New Intelligent ThermoPlate

The TPi series has a lighter and more compact design and offers several functions for accurate temperature management, for broad use in biological science and industry.

• Compact controller: the controller is about the size of a smartphone and saves space on the workstation. Controller dimensions: W85 × D135 × H30 mm; volume 232 cm³; weight 170 g.
• One-step temperature calibration: the thermo plate can be calibrated with a single operation to suit different experimental environments. Each Tokai Hit thermo plate consists of a controller and a plate that are calibrated as a matched pair before shipment, at an ambient temperature of 25 °C ± 2 °C, with the temperature at the center of the plate surface set to 37.0 °C.
• 10-year warranty against glass breakage: the transparent glass heater uses tempered glass and carries a 10-year warranty against breakage (some models are excluded).
• Continuous-output control: built on PID control, continuous-output control suppresses focus drift more effectively than conventional on/off duty-ratio control.
• LED indicator on the plate: the temperature status can be confirmed without looking at the controller; the green LED lights when the plate surface temperature is stable.
• Simple temperature measurement: the supplied sensor measures the actual sample temperature, which can be used to verify the plate surface temperature. With the temperature management software TEM, the measured sample temperature can be displayed and recorded on a computer.

Transparent glass thermo plates and metal thermo plates

• Transparent glass thermo plates: for temperature management during transmitted-light and fluorescence (I/F) observation of cells and embryos. Controllable plate temperature: room temperature to 60 °C (some models excluded). Models are available for a wide range of inverted, upright, and stereo microscope stages, including Nikon Ti2, Ti, TE2000, TS2R, TS2, TS, TMS, Ni, Ci, 90i, 80i, 55i, and 50i, and SMZ25, SMZ18, SMZ1270, SMZ1500, SMZ1000, and SMZ800 stereo microscopes, together with general-purpose and large-format glass plates.
• Metal thermo plates with an observation hole: for high-magnification and oil or water immersion observation. Controllable plate temperature: room temperature to 60 °C. Continuous-output control minimizes focus drift, which is a common concern in time-lapse imaging.
• Expansion products: objective heater (TPiE-LH), tubing heater (TPiE-TH), and large-format thermo plates (TPiE-SP / SPE).

Dual-channel controller, full-surface heating plates, KW series and heating and cooling plates

• TPiD dual-channel controller (optional): one controller drives two thermo plates, in any combination, for example a glass plate for an inverted microscope with a glass plate for a stereo microscope, or a metal plate with an objective heater.
• Full-surface heating thermo plates: manage the temperature of samples before, during, and after observation. Controllable plate temperature: room temperature to 50 °C. The whole surface of the plate is heated, so samples waiting for observation are kept at temperature as well as the sample being observed.
• KW series compact box-type thermo plate: a box-type thermo plate with a CO₂ gas port. Temperature control range: room temperature to 50 °C (plate surface temperature). A dual-heater design with a top heater and a stage heater allows the best sample temperature to be maintained, and multi-well plates can be used directly.
• Heating and cooling thermo plates: suitable for observing samples such as nematodes, fruit flies, marine organisms, zebrafish, and plants. Controllable plate temperature: 4 to 60 °C. Semiconductor (Peltier) cooling combined with an independent control system provides fast heating and cooling response.
