For (algebraic) tensor products, it is well-known that the functor $A\otimes_R \cdot:Mod_R\rightarrow Mod_R$ is only (left-) exact when $A$ is a flat $R$-module.  In partiuclar, all vector spaces are flat.  What happens in the continuous (archimedean) setting?:


Let $B$ be a separable infinite-dimensional Banach space and suppose that $
f:E\rightarrow F,
$
is a continuous linear injective map from a separable nuclear space $E$ to a separable Banach space $F$, both infinite-dimensional (if it matters).  Let $\otimes_{\epsilon}$ denote the [injective tensor product][1] of LCS.  

Is the map
$
1_{B}\otimes f: B\otimes_{\epsilon} E \rightarrow B\otimes_{\epsilon} F,
$
a continuous linear 1-1 map also?
