Ekstruderji

Ekstruderji

Ekstruderji se uporabljajo za natančno in kvalitetno mešanje, stiskanje in procesiranje viskozne snovi. Tako jih v laboratorijih uporabljamo za simuliranje in optimizacijo proizvodnega procesa, medtem ko pri farmacevtskih raziskavah, razvoju in produkciji uporabljamo ekstruderje z dvojnim vijakom (Twin-Screw Extruders) za visoko-temperaturno ekstrudiranje ter granulatorje z dvojnim vijakom za ponavljajočo granuliranje.

Micro kompounderji

Micro-compounders are suitable for  early material development when only a few grams of sample available for testing . For example, 5 grams is sufficient with a micro-compounder.

All micro-compounder models are equipped with a back-flow channel and a bypass valve which allow control of the residence time of the sample in the compounder. Depending on the compounder model, it is also possible to measure the relative sample viscosity at different screw speeds. When combined with a mini injection molding machine, scientists can produce specimens for further analysis from limited sample amounts.


Ekstruderji za farmacevtske aplikacije

Farmacevtski kompounderji od Thermo Scientific za ekstrudiranje z vročim taljenjem in za neprekinjeno granuliranje ponujajo zanesljive rešitve za odkrivanje in razvoj zdravil. Naši farmacevtski ekstruderji ustrezajo široki paleti aplikacij za razvoj zdravil in so idealni za razvoj ter testiranje receptov z dragimi API in povezanimi spojinami.


Ekstruderji in kompounderji

Z uporabo kompounderjev in ekstruderjev Thermo Scientific dosežite zanesljiv scale-up, skrajšan čas do prodaje in nadzorovano neprekinjeno obdelavo. Naši dvo-vijačni kompounderji ponujajo prilagodljive konfiguracije kompoundiranja za majhne serije bodisi za pilotno proizvodnjo bodisi za proizvodnje majhnih količin in so zelo primerni za raziskave in razvoj v polimernem, farmacevtskem, biološkem in nanotehnološkem sektorju. Farmacevtski proizvajalci se zanašajo na naše dvo-vijačne ekstruderje, da ustvarijo enotne mešanice materialov za pripravo različnih dozirnih oblik za API z nizko topnostjo. Naši instrumenti skrbijo za širok spekter procesnih zahtev za celo najzahtevnejše formulacije zdravil.


Torque reometri

HAAKE™ PolyLab OS Modular Torque Rheometer

The Thermo Scientific™ HAAKE PolyLab OS is a state-of-the-art measuring mixer and extruder system that is focused on the specific needs in research and development. The HAAKE PolyLab OS provides you with process-relevant material data including: Melting behavior, influence of additives, temperature stability, shear stability and melt viscosity. Furthermore, this measuring mixer and extruder system supports you in process modelling activities such as: Compounding polymers with additives to reduce flammability, viscosity, etc., scale-up extrusion processes by using different L/D ratios to extrapolate to your master process line, simulating master processes using only as little as 50g of material to optimize extrusion or mixing in respect to temperature and shear profile or extrusion of strands, profiles or films in combination with rheological or optical measurements.
