The built-in time scale shaper provides a pulse signal of 1 c at the output of the device. Its small dimensions, weight, power consumption, and operating time allow it to be widely used as an embedded source of high-stability signals in frequency measuring devices and complexes, telecommunications systems, navigation and communication systems. It includes a frequency binding module based on a pulse signal of 1 s from an external time scale or from a SRNS GLONASS/GPS receiver and a tunable frequency synthesizer with the ability to adjust the frequency via the RS-232 interface. The built-in binding module allows the device to be used when operating in automatic correction mode as a source of a highly stable signal with a frequency error of ± 5 · 10-12 per day.

Laboratory stick, disposable, for separating and removing a clot of p/s A stick for separating, removing a clot is a professional laboratory tool. It is used in diagnostic and research medical institutions, in biological and microbiological laboratories, etc. A smooth polystyrene stick can be used for decanting when separating sediment, biological material, and blood clot separation. The stick with a length of 15.7 cm and a diameter of 3 mm is made of transparent impact-resistant polystyrene. On the one hand it has a slightly curved pointed tip, on the other hand it ends with a flat extension. Country of origin: Russia It is possible to change the color of the goods, the quantity in the package in agreement with the customer!

• Designed for: • – detection of depressurization sites of underground pipelines of heat, water, gas, oil supply systems located at a depth of up to 3 m in channel and without channel laying. • – traces of hidden communications (cable lines, pipelines) in passive mode. • – surveys of the excavation area (before opening the route for the presence of cables, pipelines that complicate excavation).

DPSS lasers of the KLM-522/x series are optimal sources of coherent radiation for the construction of control and automation systems, alignment and marking devices, for scientific and medical purposes.

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.
