We've been running these for a while now, and the brushless DC motor is noticeably quieter than the old brushed ones — it's basically silent at low speeds, which matters when you've got a lab full of them running at once.

Most buyers go with the 30° tilt for standdard blood sample mixing, but if you're working with thicker liquids or need a more aggressive rock, the 40° option handles it better.

It handles 1kg load capacity without struggling, and the speed range goes from 0 to 30 rpm — you'll want it at about 10-15 rpm for typical anticoagulant tubes, though we usually have stock, but confirm lead time if you need the 405mm length version for larger racks.
The 15W power draw means it can run 24/7 on a standard 100-240V outlet, and the operating enviroment limits (5-40°C, 80%RH) are pretty standard — just don't put it directly under an AC vent or you'll get condensation issues.

We've got three model variants (SK-R30S-E is the shorter 295mm one, SK-R30L-E at 345mm, SK-R30D-E at 405mm), and they all weigh between 1.8kg and 2.2kg — lighter ones are easier to move around, but the bigger footprint gives you more tube capacity.

CE and ISO13485 cerification is there, but what it really means is the tilt angle holds within ±3° under load — better than some generic rotators that sag after a few months.
The main difference is size and weight. The SK-R30S-E is the smallest at 295×160×120mm and 1.8kg, while the SK-R30L-E and SK-R30D-E are larger, up to 405×160×160mm and 2.2kg. All share the same 0-30 rpm speed range and 1kg load capacity.
No, each unit is fixed at either 30±3° or 40±3° tilt angle — you pick the angle when ordering. If you need both angles, you'd need two separate units.
We typically require a MOQ of 10 units for this model, but we can discuss smaller trial orders for first-time buyers. Lead time is around 15-20 working days after order confirmation.
Yes, we include copies of the CE and ISO13485 certificates with every order. If you need the documents before shipping, just let us know and we'll email them.
Store it in a clean, dry place within 5-40°C and below 80% humidity — essentially the same as its operating environment. No special packaging needed, but keep it away from direct sunlight and dust.
