Tenders are invited for Purchase of Ultrasonicator
with sound-proof case
MWNTs were initially ultra-sonicated using Ultrasonicator
(Vibronics, India, frequency 20 KHz; sonication time: 10 min).
(QSONICA, LCC) with 1/8" micro-tip is used to prepare electrostatically stabilized dispersion of nanoparticles in binary liquids.
The energy input of the ultrasonicator
is around 100 W for 270 seconds.
The dry mycelia were then suspended in methanol, homogenised, and then sonicated in an ultrasonicator
at room temperature.
Leaf samples (200 mg) were extracted with ultrasonicator
(Cell Disrupter Ultrasonic Probe, Model 1000L) at 4[degrees]C in a 10 ml aqueous acetone solution (acetone/water: 7/3 v/v).
Frozen plankton samples in seawater were thawed at room temperature and sonicated for 2 min in a water bath ultrasonicator
(Branson ultrasonic cleaner; Branson Ultrasonics Co.
The ball milled nanoparticles were dispersed in ethanol using ultrasonicator
and its morphology was observed in Philips CM12 transmission electron microscopy (TEM).
Specimens were prepared for scanning by cleaning in a Branson 1510 Ultrasonicator
, dried with a Denton DCP1 Critical Point Dryer, coated with AuPd with a Denton Vacuum Desk II Sputter Coater and examined with a Hitachi S-520 Scanning Electron Microscope.
22 [micro]m membrane filter and degassed by ultrasonicator
using frequency 40 KHz.
