نقد و بررسی تخصصی سانتریفیوژ Hettich مدل Micro 220 R
The MIKRO 220 R is a compact benchtop centrifuge that is used for microlitre applications The centrifuge can hold up to 60 x 1.5 / 2.0 ml tubes per run. It has a maximum acceleration of 31,500 x g and delivers results very fast.
The MIKRO 220 R is the refrigerated version of the MIKRO 220. The cooling function enables temperatures to be set anywhere in the range -20 °C to +40 °C. The MIKRO 220 R also has a fast cool function.
Its extensive range of accessories allows centrifugation of tubes with a volume up to 50 ml.
Its outstanding performance makes the MIKRO 220 R an invaluable tool for sample preparation in the fields of gene sequencing, virology, bacteriology and routine applications in clinical laboratories.
Its quiet operation with a low level of vibration means that noise levels are kept low.
The MIKRO 220 R is very user-friendly and offers a number of features:
- Motor-driven lid locking
- Ergonomic operating and information display
- Simple rotor change
- ۱۰ programmable memories
- Entry of the rotor radius in mm enables switching between display of rpm and RCF (relative centrifugal force)
- Parameters can be entered or changed rapidly and easily using the rotary button
The MIKRO 220 R contributes to safety in the workplace. It has the following features to promote safety:
- Lid locked when rotor is running
- Lid fall prevention mechanism
- Emergency lid release in the event of power failure
- Motor overheating protection
- Imbalance shut-off
- Automatic rotor recognition
- Accessories with bioseal (TÜV tested in accordance with DIN EN 61010, Part 2) to protect against dangerous or aggressive aerosols
The MIKRO 220 R is a compact, easy-to-clean benchtop centrifuge with the following features:
- Metal casing
- Metal lid
- Centrifugation chamber of rust-free stainless steel
- View port in the lid
- ۹ different rotors: in addition to the standard rotors, it has a 24-place swing-out rotor, a 20-place rotor for cryotubes and a rotor that can hold 6 PCR strips
Advantages
- Outstanding centrifugation results within a very short time
- Very short run-up and run-down times without causing re-suspension of the sediment
- High RCF: 31,514 with an angle rotor and 18,516 in a swing-out rotor
- Maximum capacity: 60 x 1.5 / 2 ml
- Comprehensive range of rotors
- Accessories that are impermeable to aerosols, autoclavable and phenol-resistant
- The operating and display features of the MIKRO 220 R are ergonomic in design
- Pulse key for short centrifugation runs
- ۹ braking and start-up ramps and run-down without braking can be selected; ramp 9 represents the shortest braking and start-up times
- Large display which is easy to read, showing the current status of all parameters when the centrifuge is running
- Quiet operation and low vibration
- The robust construction of the centrifuge and the rotors ensures a long service life even under intensive use
- The cooling function enables temperatures to be set anywhere in the range -20 °C to +40 °C, with fast cool function
