Robinson has yet to figure in a warm-up game this summer after undergoing a double hernia operation while fellow centre-back Lowry suffered a groin strain during the tour of Ireland last month.
Jackett, speaking after his side's 3-2 win at Exeter on Saturday, added he was pleased with the workout his players had been given by the npower League Two outfit.
"Maik Taylor wasn't involved because David Forde needed a game but he's fine and hopefully Robinson and Lowry could be involved at Southend on Tuesday night," Jackett told the club's official website. "Everyone else who needed it got game-time at Exeter which was also important.
"Exeter play a style of football we will encounter regularly in the Championship this season. Tactically they posed us the sort of problems we will have to deal with in the coming months, so it was very useful from that point of view.
"After the defeat at Crawley, a win was important for us at this stage, but there is still plenty to work on."
