Vacuum valves are designed to cut off and seal the elements of the vacuum system, thereby, vacuum valves provide the necessary sequence of pumping and air intake. The vacuum valves presented in this section are mass-produced by NPO Helikon.

Regulated switching power supplies with highly stable output characteristics Digital display of set and actual value, voltage and current (4 digits, LED) Electronic load switching on/off Protection against overload, short circuit, overheating and reverse polarity Low ripple output voltage less than 2mV Low ripple output current less than 5mA Minimum discreteness of setting output voltage and current 0.007/0.005 Operating modes: stabilization U and I, dynamic load RS-232 interface

The universal design of the table frame allows you to equip the workplace with a hanging pedestal and other necessary equipment. Additionally, work tables of Comfort series can be equipped with a number of modules: a reinforcing bar, electrical and perforated panels, overhead and local lighting, shelves for equipment, hanging cabinets, corner tables.

When lining up, Classic series desktops fit snugly together, without forming cracks and gaps. The universal design of the table frame allows you to further equip the workplace with a suspended pedestal and other necessary equipment. Additionally, work tables of Classic series can be equipped with a number of modules: electrical and perforated panels, overhead and local lighting, shelves for equipment, hanging cabinets, corner tables, etc.

The working table of Gamma series is supplied in a set: a working table with side racks, a main shelf, overhead lighting, upper and lower punched panels and a side power unit. Quick-detachable side panels provide easy access to internal communications.
