The Low Speed Centrifuge (DM0436E) is a large-capacity benchtop centrifuge designed for high-throughput clinical diagnostic sample processing, blood component separation, urinalysis, and general laboratory applications. With a standard rotor capacity of 36 × 5/7/10 mL vacutainer tubes, this centrifuge provides the throughput needed for high-volume clinical laboratories while maintaining low-speed operation optimal for serum and plasma preparation.
For the medical technologist and clinical laboratory scientist, the DM0436E facilitates serum and plasma separation for blood chemistry testing (liver function tests, renal function tests, electrolytes, glucose, lipid profiles), coagulation studies (PT, PTT), and routine hematology workflows. It supports urinalysis sediment preparation for microscopic examination, cerebrospinal fluid cell concentration for neurological diagnostic testing, blood bank compatibility testing for transfusion medicine, and nucleic acid extraction for molecular diagnostics.
The centrifuge features a maintenance-free brushless DC motor, LCD display with speed/RCF switchover, quick spin (PULSE) function for instantaneous centrifugation, and tool-free rotor exchange for versatile application switching. The standard rotor accommodates 36 × 5/7/10 mL vacutainer tubes, with optional rotors available for 50 mL conical tubes, 15 mL tubes, 20 mL urine tubes, and 32 × 5/7 mL configurations, as well as tube adapters for smaller blood collection tubes.
Safety features include door interlock, over-speed detection, imbalance detection alarm, and over-temperature protection, with CE safety certification. The DM0436E provides reliable, high-throughput performance for routine laboratory workflows supporting patient diagnosis and treatment monitoring.

  • How it helps: For the laboratory manager, the multiple rotor options eliminate the need for several dedicated centrifuges—allowing a single instrument to handle blood tube processing (including 10 mL, 7 mL, and 5 mL vacutainers), urine concentration, and specialized applications. For the patient, versatile equipment ensures that diagnostic testing can be performed efficiently across multiple test types without equipment delays.
3. Serum and Plasma Preparation for Clinical Chemistry
  • Primary Use: Supports serum and plasma preparation for standard blood chemistry panels including liver function tests, renal function tests, electrolytes, glucose, and lipid profiles using standard vacutainer tubes.
  • How it helps: For the clinical chemist, the DM0436E’s consistent low-speed operation ensures optimal separation of serum and plasma without hemolysis or cellular damage—improving the accuracy of routine chemistry testing. For the patient, high-quality sample preparation reduces the need for repeat blood draws and ensures reliable diagnostic results for common health screenings.
4. Urinalysis and Body Fluid Sediment Preparation
  • Primary Use: Accommodates urine tubes and conical tubes for urine sediment preparation, as well as cerebrospinal fluid and other body fluid samples for microscopic examination.
  • How it helps: For the clinical laboratory scientist, the DM0436E’s low-speed, gentle centrifugation preserves cellular morphology while effectively concentrating sediment elements—improving microscopic diagnostic accuracy for urinary tract infections, kidney disease, and neurological conditions. For the patient, accurate sediment preparation supports correct diagnosis of conditions requiring urinalysis and body fluid testing.
