Recently, Microspheres are gaining an
important place in many fields due to their due to their special size,
structure and properties. Especially, Long-acting microspheres, as a kind of
micron level drug carrier, are made from drug dissolving or dispersing in
polymer materials. This new dosage form can significantly reduce dosing
frequency, improve the stability and reduce the side effects of drugs in
Pharmaceutical Industry.
Figure1. Microspheres are gaining an important place in many fields
Microsphere Preparation
Most of the microspheres obtained by
traditional preparation methods have some problems, such as complicated
manufacture processes and difficulties in quality control, which greatly limits
their applications.
Microfluidics is the technology of fluid
manipulation in channels with dimensions of tens of micrometers. Therefore,
emulsion or liquid droplets with good dispersity, particle size and morphology
can be prepared continuously and controllably.
By solidifying the droplets, the
microspheres can meet the requirements of bioanalysis or drug screening
carrier.
Figure2. Demonstration of droplet-based
microfluidics
A safe, precise and intuitive pump
A university experiment has chosen Longer TS-1B
/ W0109-1B syringe pump as the liquid delivery of microfluidic system to fabricate
Microsphere.
TS-1B / W0109-1B syringe pump provides
sufficient conditions for fabricating uniform microspheres with intuitive
interface, simple operation, multi-channel independent control, stable flow and
high precision.
As mentioned above, the key to the normal
operation of the microfluidics system is to generate droplets with uniform size
and stable flow velocity. As the power source of the whole system, the pump
provides precise flow and stable power to produce micro droplets.
New syringe pump opens new possibilities
for experiments
Figure4. dLSP500 Digital laboratory Syringe
The dLSP500 Digital laboratory Syringe
Pumps have a wider overall flow range with the option of dosing between
0.0007nl/min-57.621ml/min. The models pack in advanced features designed to
deliver fluids accurately, especially in microfluidic system, dLSP 500 syringe
pumps can provide steady micro flow delivery with small pulsation and good
stability.
Longer pumps are renowned for high
accuracy, precision, and reliability during processes critical for fluid
delivery functions and support microfluidic chips for a diverse range of
applications.
