Le trappole fredde con vaso di Dewar sono costruite in vetro borosilicato 3.3 a norme DIN/ISO 3585 a tenuta LN2 per applicazioni di vuoto. I vasi sono isolati e placcati argento. Sono incassati in alluminio, per protezione, ed hanno un collare ad anello in plastica, all"interno del quale è inserita la trappola fredda. In questo modo non è necessario nessun supporto supplementare. I vasi Dewar hanno una capacità teorica di refrigerante di 1.0L o 2.0L. Le trappole fredde hanno una capacità teorica di condensato di 150ml o 250ml.
Articoli forniti: Trappola fredda, vaso Dewar, anello in plastica.

Dewar Tipo 12C/18C: vedi cod. 9.032.024 / 9.032.030
Tipi di giunti delle trappole fredde :
S 29 = giunti sferici
GL 18 =in vetro con testa a vite con oliva in PTFE 10mm
O 29 = giunti sferici S 29 con guarnizione O-ring

L"assemblaggio standard è studiato per uso con LN₂ come refrigerante. Quando si utilizza acetone si prega di ordinare separatamente la griglia CO₂(Dewar Tipo 12 C Cod. 9.032 081 e Dewar Tipo 18 C Cod. 9.032 082)

Two-piece cold trap made of stainless steel with KF NW small vacuum flange.

For cooling and storage of temperature-sensitive goods e.g. with dry ice (CO₂). Handles as indicated.

• Cylindrical
• Made of stainless steel

In vetro borosilicato 3.3, in due parti, bottiglia con cono smerigliati normalizzati su cui è fissata una testa con attacchi laterali, a scelta con olive portagomma o coni normalizzati.

Le trappole fredde vengono utilizzate insieme alle pompe da vuoto per raccogliere il condensato prodotto dall"umidità o dai solventi e possono essere usate per molte funzioni. L"applicazione più comune è raccogliere la condensa prodotta da umidità o solventi da dischi rotanti, pompe da vuoto o sistemi per alto vuoto che usano pompe a diffusione d"olio o turbo-molecolari. In questo caso si utilizza normalmente un refrigerante comune come azoto liquido (LN2) o ghiaccio secco (CO2) con acetone. Semplici trappole fredde, note anche come condensatori a dito freddo, sono usate in combinazione con le pompe da vuoto e la condensa viene spinta fuori dall"umidità o dai solventi utilizzati nelle applicazioni chimiche.
La trappola fredda è usata per proteggere la pompa da vuoto e la specialità di questo tipo di costruzione è che l"utilizzatore non necessita di un supporto per la trappola fredda. Tramite un bordo, la trappola fredda viene appesa all"interno dell"anello di supporto dei vasi Dewar. E" possibile sostituire velocemente la trappola fredda, senza che si verifichi nessun problema.

Stainless steel cold trap with Dewar flask for vacuum applications. Ideal for condensing out moisture or solvents. Dewar flask made of stainless steel with support ring into which the cold trap is hung.

• Cold trap connection: KF NW small vacuum flange
• Spring steel clamp to secure the connecting part (KF NW 50)
