There
is the narrowest gap (clearance) between rotating inner and outer blades.
The clearance of Physcotron generator is manufactured less than 20 micrometers
(NS-10, 20, 30U).
Please let us know your application. We are happy to suggest the best combination of drive-unit and generator!
There are two types of generator shafts for medium to large drive units: 1. Open and 2. Closed types.
1. Open-type generator shafts
Open-type generator shaft has slits on its outer blade which is a fixed cylinder. The slits work for rotating cooling.It suppresses heat elevation due to ultra-high rotation and prevents the sample from being denatured by heat.
The below are open-type generator shafts for medium to large drive units.
| Small volume type | NS-10, NS-10M, NS-10G |
|---|---|
| Universal type | NS-20, NS-20M, NS-20G |
| Sharp type | NS-20S |
| Ultrasonic type | NS-30U, NS-30UG |
| Shaft for separate-type generators | NS-10P, NS-20P |
Open-type generator shaft has two types: All-in-one and Separated types.
For all-in-one type, a generator and a shaft are combined together and cannot be detached.
For separated type, the blade edge can be detached and replaced to another one as below.
When the blade of generator is worn out, it's not necessary to replace the whole generator shaft. Only the generator, blade edge can be replaced. The separated type is economical and environmental-friendly.
2. Closed-type generator shafts
Closed-type generator shaft has no slit so that almost no liquid solution comes into the shaft. It prevents sample residue being mixed into inside. It is suitable when contamination prevention or chemical-resistant ability is required.
The below are closed-type generator shafts for medium to large drive units.
| Small volume type | NS-10G, NS-10GM |
|---|---|
| Universal type | NS-20CG, NS-20G, NS-20GM |
| Sharp type | NS-20SG, NS-20SGM |
| Agitation type | NS-20MG |
| Ultrasonic type | NS-30UG |
| Multiplexed ultrasonic type | NS-35UG |
| Large volume type | NS-35G |
| Shaft for separate-type generators | NS-10TP, NS-20TP |
Closed-type generator shafts are all separated type (no all-in-one).
3. Micro-shafts
Micro-shafts are exclusively for handy micro-homogenizers
handling a small amount.
A highly-accurate blade edge by micro-processing technology homogenizes
your sample efficiently in a short period of time.
| Ultra-trace amount type (world's smallest shaft) | NS-3 |
|---|---|
| Trace amount type | NS-4 |
| Small amount type | NS-7 |
An example of a set of three micro-shafts |

NS-3M
Trace amount type NS-4
Size:
4.5φx80mm, Sample volume: 100µl-5ml
Short-time process and suppression of thermal denaturation are simultaneously
achieved.
Best suitable for trace amount of valued sample.
Dry-heat type (*1): NS-4M
Small amount type NS-7
Size:
7.0φx100mm, Sample volume: 0.5-50ml
Standard type for micro-shaft series.
It can be widely used for microtubes to 50ml centrifuge tubes.
Dry-heat type (*1): NS-7M
Open-type generator shafts

Suitable for dispersion, agitation, and emulsification of fine samples by
ultrasound effect.
Separate-type (*2): NS-30UG
Shaft for separate-type generator NS-20P

Suitable for homogenization, emulsification, dispersion, and chemical
combination.
Please use it with a shaft, NS-10TP.
Dry-heat type (*1): NS-10GM
Universal type NS-20CG
Size:
