The Long Deck Double Layer Rocking Rotator is a long-deck double-layer rocking rotator featuring adjustable speed control (0-30 rpm), fixed 40° tilt angle, continuous operation mode, and a maintenance-free brushless DC motor, designed for gentle, uniform mixing of blood tubes, serology specimens, and molecular biology samples in clinical diagnostic and research laboratories .

Key features include a double-layer deck design (405mm length) that accommodates up to 16 × 5-10mL blood collection tubes or 6 × 50mL centrifuge tubes per layer (up to 32 tubes total) using interchangeable silicone mattresses, fixed 40° ± 3° rocking motion for gentle, thorough mixing, continuous operation mode for extended use, analog speed control (0-30 rpm), and a maintenance-free brushless DC motor for quiet, reliable operation . The unit's compact footprint (405 × 160 × 160 mm) and lightweight design (2.2 kg) allow easy benchtop placement .

The SK-R30D-E accommodates a variety of tube formats via interchangeable silicone mattress accessories, with universal voltage (100-240V, 50/60Hz) enabling use in laboratories worldwide without voltage conversion . The cold room and incubator compatibility (5-40°C operating temperature, ≤80% RH) allows sample mixing under controlled temperature conditions for temperature-sensitive applications .

For the clinical laboratory scientist and phlebotomist, the SK-R30D-E ensures gentle, thorough mixing of blood samples after collection—preventing clot formation, platelet activation, and hemolysis that could compromise complete blood count (CBC) and coagulation study (PT/PTT) results . For the immunology technologist, it supports RPR and VDRL serological testing for infectious diseases (HIV, syphilis, hepatitis) . For the molecular biologist, it facilitates gentle mixing of DNA, RNA, and protein samples for PCR and sequencing workflows .

Universal voltage (100-240V, 50/60Hz) enables use in laboratories worldwide without voltage conversion . The double-layer design maximizes throughput while maintaining a small benchtop footprint . The silicone mattresses provide secure tube retention and are easy to clean and decontaminate between sample batches .

For the patient undergoing coagulation monitoring (warfarin, heparin), complete blood count (CBC), serological testing for infectious diseases, or molecular diagnostic testing, the SK-R30D-E's gentle rocking motion ensures accurate test results that guide appropriate treatment decisions—preventing false-negative or false-positive results due to improper sample mixing, clot formation, or platelet activation .
