The EBA 200 is the smallest centrifuge produced by Hettich. It is capable of speeds up to 6,000 rpm which equates to a maximum RCF of 3,461 xg. This centrifuge has a capacity of 8 x 15ml making it the ideal choice for small clinical practices who want to centrifuge their own blood tubes. Adaptors are available for users who wish to spin smaller tubes.

Like the EBA 200 and EBA 200 S, the EBA 270 is a small capacity centrifuge designed to spin 15ml tubes. The difference is that the EBA 270 will spin these 15ml tubes in a swing-out rotor, not an angled one. This means that separation will be flat. The EBA 270 can spin 6 x 15ml tubes up to speeds of 4,000 rpm (2,254 xg). There is a wide range of adaptors available for users who wish to spin smaller tubes.

The Mikro 185 centrifuge is a super versatile micro-centrifuge designed to spin 24 x 1.5/2ml micro tubes up to speeds of 13,300 rpm. This equates to a maximum RCF of 17,008 xg. There are various tube adaptors for users who want to spin smaller tubes. Like most Hettich centrifuges, the Mikro 185 is IVD compliant meaning that it meets the standards of the European directive 98/79/EC.

The Mikro 200 is one of the fastest centrifuges in its class. It has the same capacity as the Mikro 185 but it can spin up to 30 micro tubes instead of just 24. The maximum speed is slightly higher too at 15,000 rpm (21,382 xg). There are six rotors available which will cover most clinical applications. All rotors can be supplied with lids. There are also some tube adaptors which can be used for accommodating smaller tubes in the same rotor.

The Rotanta 460 has a capacity of 4 x 750ml and can reach speeds up to 15,000 rpm which equates to 24,400xg. This 3 litre centrifuge is a real workhorse and has nearly 30 different rotor/bucket combinations at its disposal. This centrifuge is ideal for users with a high through-put of tubes.

The Rotanta 460 is also available in a floor-standing version for users who have limited bench space. The Rotanta 460 RC is approximately 68cm high which makes it an ideal under-bench centrifuge. This frees up space on the bench for other laboratory equipment.

The Rotixa 500 RS is a large capacity, refrigerated centrifuge capable of spinning samples up to 1 litre at 10,000 rpm. The 4 x 1,000ml rotor uses square buckets to process tubes and round one to process blood bags. The round buckets can accommodate single, double, triple or quadruple blood bags. A set of balancing weights are available to make up the weight difference when spinning blood bags of difference weights.

The Roto Silenta 630 RS is the flagship centrifuge model from Hettich. It is designed to spin very large quantities of tubes and blood bags at speeds of up to 6,000 rpm (6,520 xg). Ideally suited for blood bank environments, the Roto Silenta 630 RS can spin quadruple bags from a variety of different manufacturers including Baxter/Fenwal, Fresenius and Terumo. The 2,000ml bucket is more than capable of accommodating blood bags including ancillary tubing and filters.
