New PENETO ANALYZER - Malayan Daching

Measuring speed & weight of the liquid to penetrate

into powder layer. This gives affinity between liquid

& powder;namely, Wettability. It is widely used in

pharmaceutical & chemical industry to evaluate the

surface characteristics between powder material &

various.

SUMMARY

FEATURES- Easy measurement through PC operation

- Precise lifting control of the vessel realizes accurate

measurement

- High repeatability by specially designed cell shape

- Optimal packing (option )

Measuring the penetration speed of liquid into powder layer

gives wettability of powder and contact angle of liquid & powder

.These operation is automated by computer

SPECIFICATION

MEASUREMENT SAMPLEPowder : A, B & C , Liquid : water

The measurements give three different curves Fig.1. Penetration speed coefficient through Washburn’s equation is shown in Fig.2.

Fig.1 Comparison of penetration speed on each samples Fig.2 Gradient gives penetration speed coefficient

WL : liquid penetration weight, t :time, S : cell projection area

e : void ratio, rL : liquid density, r : radius of capillary formed in powder layer

gL : surface tension of liquid, ηL : viscousity of liquid,

q : contact angle between liquid and solid surface
