HETTICH UNIVERSAL 320
UNIVERSAL 320
There are good reasons why we have called this centrifuge UNIVERSAL. Its excellent performance and comprehensive range of accessories enables it to carry out virtually any centrifuging task.
In the low speed range, the UNIVERSAL 320 processes standard tubes up to a volume of 100 ml, microtitre plates, conical tubes with screw cap, blood collection tubes and cyto accessories. Microlitre tubes can be accelerated to an RCF of 21,382. Centrifuge tubes taking higher volumes (up to 85 ml) also profit from the extraordinary motor power of the UNIVERSAL 320. At an RCF of 9,418, bacteria and yeast sediment quickly and easily.
As the UNIVERSAL 320 can be used as general and special purpose centrifuge, it is not only cost-effective, it also saves valuable space in the laboratory.

NEW! Arcobacter Broth
Arcobacter butzleri is the fourth most common Campylobacter-like organism isolated. A. butzleri displays microbiologic and clinical features similar to those of Campylobacter jejuni.
Arcobacter Broth base (Fluka 59848-500G) with CCDA Selective Supplement (Fluka 77093-5VL) is selective for A. butzleri and suppresses the growth ofCampylobacter and other species. |

Silylation Reagents for GC Derivatization
Silylation is the most widely used derivatization procedure for sample analysis by GC. The
popularity of silylation reagents is enhanced by their ease of use and formation of volatile derivatives. Fluka offers a comprehensive range of high performance silylating reagents including some specialties like methallylsulfinates, which don’t require any additives and
convert the analyte within a few minutes. For more information please visit our website:
