Liquid thermostats from Primelab are reliable and high-quality devices for maintaining and controlling liquid temperature in laboratory conditions. Models with different bath volumes (4 liters, 8 liters, 15 liters, 30 liters) allow you to choose the appropriate option depending on your needs and volume of work. The pump capacity is 15 liters per minute, which ensures efficient circulation of liquid in the bath. Digital/intelligent control allows you to easily and accurately set and maintain the desired temperature. The temperature control range from +20 to +200 degrees Celsius provides the ability to work with a wide range of substances and laboratory processes. Liquid thermostats from Primelab are the ideal solution for laboratories and scientific research, guaranteeing accuracy, reliability and ease of use.

The TL-4 circulation thermostat from the TL Primelab family is a reliable and effective solution for maintaining the set temperature of objects in the bath and in the external circuit. This model is designed to work with water as well as non-aqueous fluids, making it a versatile tool for laboratory and industrial processes. Design Features: The intelligent control system adapts the parameters of the PID controller to the type of working fluid, ensuring stable operation of the system even when the network voltage is unstable or the air temperature changes. The circulation pump effectively mixes the coolant in the bath and ensures high accuracy in maintaining the temperature of the external system, both closed and open. A reliable heating element guarantees safety and stable heating of the coolant. The display shows the current and set temperatures, setting values and service parameters, and the multifunctional control knob ensures ease of use. A safety device with sound and light warning automatically turns off the heating in the event of a break in the temperature sensor circuit or the coolant level drops below the permissible level. The working bath is made of stainless steel, has a long service life and is easy to clean. The outer body of the steel bath is thermally insulated and powder coated for safe operation even at high temperatures of the working fluid. The circulation thermostat TL-4 from Primelab is quality, reliability and convenience in one device. Rest assured that your process temperature control is accurate and stable.

To achieve the maximum sensitivity during measurements, a special prefix is used to the FT-801 Fourier spectrometer, which is an optical unit with a built-in highly sensitive MST detector cooled with liquid nitrogen. The set-top box is installed in the cuvette compartment of the spectrometer and connected to the corresponding external electrical port, the detector is turned on programmatically. In this case, the sensitivity of the method increases many times (up to 20) – depending on the type of standard uncooled detector in the spectrometer). The speed of recording spectra is also increasing. The operating time after filling the cryostat (200 ml capacity) with liquid nitrogen is at least 6 hours. Increasing the sensitivity of the spectrometer using a prefix with an MST detector may be required for many applications: in fiber spectroscopy, when recording emission spectra of low-power emitters, in trace gas analysis with high spectral resolution, when determining the presence of impurities in samples in ultra-low concentrations, when using multi-pass gas cuvettes, etc. In the picture: on the left in the cuvette compartment there is a capler with fiber from Art photonics GmbH, Berlin, Germany, on the right there is a prefix with an MST detector. Technical specifications The recommended number of scans when registering spectra is 16 Spectrum registration time at 50 scans (resolution 4 cm-1), sec 20 Cryostat capacity, 200 ml Working time after filling the cryostat, 6 hours Overall dimensions, mm 225×175×75 Weight, kg 1.45
