TDL-6C / TDL-5A / TDL-4C low speed centrifuge procurement decision notes
The TDL-6C is the compact, highest-speed model in the HQS TDL low speed centrifuge series. It reaches 6000 rpm and 4470 ×g with Rotor 7 (15 ml × 12); its standard swing rotor takes 100 ml × 4 at 5000 rpm and 4390 ×g, and six further rotors are offered (50 ml × 4, 10 ml × 12, 5 ml × 16, 20 ml × 8, 20 ml × 6 and 15 ml × 12). It has stepless speed adjustment, a 0–99 min timer, a brushless motor, an LCD showing speed, RCF and time, over-speed and imbalance alarms, a safety switch and electromagnetic door locks, error code display, a strong metal case and stainless steel chamber, 410 × 530 × 340 mm and 27 kg. The TDL-5A (5000 rpm, 4390 ×g, swing rotor 250 ml × 4, 50 ml × 8, 15 ml × 28, 10 ml × 36, 48 kg) and TDL-4C (4000 rpm, 2755 ×g, swing rotor 100 ml × 4, 50 ml × 8, 15 ml × 16, 10 ml × 24, 44 kg) are larger 450 × 550 × 450 mm floor-standing units with a swing rotor for four tube sizes, an LED display of speed and time and a stainless steel chamber and hood. All three run on 110 V 60 Hz or 220 V 50 Hz. Choose the TDL-6C for the highest RCF and RCF display in the smallest cabinet; the TDL-5A for 250 ml bottles or many 10–15 ml tubes per run; the TDL-4C for 4000 rpm routine serum and plasma work.
