The ISO-KF connection (DIN 28 403 and ISO 2861) allows quick installation and replacement of components in vacuum systems. The connection consists of two symmetrical ISO-KF flanges (1), a centering ring with an O-ring seal (2) and a quick-release clamp (3). High-vacuum ISO-KF connections can be mounted without using a tool by simply turning the nut of the quick-release clamp.

The tank for the 3.5 kW aquadistillator is made of stainless steel.

A high-speed signal limiter amplifier. Designed for use in electronic counting frequency meters. Description: The magnitude of the input signals for selecting the switch input and inverting the signal of the limiter amplifier at a supply voltage of ± 5 V: - logical "0" not more than 0.2 V; - logical "1" at least 4.8 V. The value of the input signals of switching on / off the switch at a supply voltage of ± 5 V: - logical "0" no more than 3.3 V; - logical "1" at least 4.1 V. The magnitude of the output signals of the switch at a supply voltage of ± 5 V and a load of 300 ohms connected to zero potential: - logical "0" from 3.1 V to 3.4 V; - logical "1" from 4.0 V to 4.3 V. The minimum input voltage of the sinusoidal shape in the frequency range from 10 Hz to 200 MHz should be no more than 30 mV. The maximum input voltage of the sinusoidal shape in the frequency range from 10 Hz to 200 MHz must be at least 1 V. The value of the supply voltage: - positive 5±0.2 V; - negative -5±0.2 V. The current consumption should be no more than: - from a positive power source 110 mA; - from a negative power supply 35 mA.

Septa for titrators are made of fluorosiloxane rubber. The main difference between this material and traditional silicone is the presence of trifluoropropyl groups in the chain, which give fluorosiloxane rubber chemical resistance to solvents, fuels, oils, acids, alkalis, and a number of oxidants, as well as a wide operating temperature range from -60 to +200℃. Characteristics of the septa produced by us for the L 51108740 titrator: Diameter -12 mm Thickness - 2 mm Color - white Density -1.50 ± 0.05 g/cm3 Hardness -60- 70 units. Shore A
