HPLC-kolonner Purospher®

Leverandør: Merck

Beskrivelse: <B>Purospher® RP-18</B> er designet til separation af problematiske basiske forbindelser med enkle, neutrale eluenter. Desuden muliggør Purospher® RP-18 separation af hydrofile forbindelser vha. en vandig, mobil fase. Purospher® RP-18 er baseret på højrent og metalfrit silica. Multitrins kemisk modifikation og deaktivering af overfladen og den polære endcapping giver en eluering af basiske og chelat-forbindelser uden top-forurening. Purospher® RP-18 er ikke egnet til separation af sure forbindelser. Purospher® RP-18's gode kemiske stabilitet gør det muligt at anvende mobil fase forhold ved pH 8 i en længere periode.

The plug-in recirculating air filter system UFA.20.30 is capable of retaining solvent vapours (hydrocarbons) permanently up to a filter saturation of more than 99,999%, under normal operating conditions as well as for a simulated accident in the safety storage cabinet.
A special version of the recirculating air filter system UFA.20.30-AUS is also available to meet the pressure conditions and volumetric flows of safety storage cabinets with a small internal volume. It can be installed on a wall bracket or in a convenient housing unit.

Shaking water baths, Clifton NE5 Series

Leverandør: NICKEL ELECTRO

Beskrivelse: Digital and analogue linear shaking water baths with a stainless steel tank housed in a durable outer case. The corrosion resistant reciprocating trolley readily accepts perforated clip trays for holding flasks and test tube racks. The trolley is easily removed for cleaning purposes and a stainless steel recessed top accommodates flasks, clip trays etc prior to and after immersion. The 28 litre baths include a drain tap for convenient emptying. Digital shakers have splash proof controls featuring an advanced PID temperature controller with a LED display, allowing observation of set and actual temperature simultaneously to 0,1 °C resolution. They also feature a highly accurate PT 100 sensor with the added advantage that it is immersed in the water for accurate temperature measurement. An over-temperature alarm operates on digital baths at 4 °C above set point which switches of the heaters to protect the users work until a safe working temperature is achieved. Analogue model has an electronic temperature controller and an electronic speed control for shaking. The heater and safety device are concealed beneath the tank allowing for easy cleaning.
