densities up to 2000 kg/m ). The centrifuge ОПн-3.02 provides setting
the frequency of rotation of test tube holder by step 1000, 1500, 3000
revolutions/minute. The electronic blocking doesn’t allow the
possibility of opening the centrifuge cover until the complete stop of
rotor. The test tube holder of the centrifuge ОПн-3.02 provides
possibility of simultaneous centrifugation of 10 test tubes;

2) The laboratory centrifuge ОПН–8 provides adjusting the
frequency of rotor rotation by steps in a range from 1000 to 8000
revolutions/minute and has a 60-minute mechanism of the time
counting out. The centrifuge ОПН–8 has the angular rotor of AR
12х10 (РУ 12х10) type or AR 8х10 (РУ 8х10) type containing up to
12 centrifugal test tubes (the volume of each test tube is 10 ml);
