Olympic silver medallist Michael Jamieson claimed silver in the 200 metres breaststroke, knocking more than a second off his British record as he took on Olympic and world champion Daniel Gyurta, leading the Hungarian with 50m to go before being caught in the final two lengths.
Gyurta won in a time of two minutes 0.72 seconds with Jamieson coming home in 2mins 1.43secs and Germany's Marco Koch third in 2:01.62.
Jamieson's British Gas ITC Bath teammate Andrew Willis also ducked under the Scot's old British record as he finished fourth in an English record 2:02.99.
Jemma Lowe claimed her second medal this week - having won 200m butterfly bronze earlier in the meet - as she won silver in the 100m butterfly.
The Bath swimmer lowered her Welsh record to reach the podium in 56.32 seconds behind Sweden's world champion Sarah Sjostrom (55.78).
Aimee Willmott and Chris Walker-Hebborn also medalled for the Brits as the 12-strong team finished with eight medals in total.
Middlesbrough swimmer Willmott continued her record-breaking form as she clinched bronze from the 400m individual medley final.
Willmott, who broke her long-course national marker seven days ago, set an English record 4:25.37 to reach the podium behind Spain's Mireia Belmonte Garcia (4:21.23) and Hungary's Katinka Hosszu (4:24.69), while Great Britain's Hannah Miley finished fourth, touching in 4:28.56.
Walker-Hebborn sealed the first major short-course medal of his career by claiming bronze in the 100m backstroke.
Having set a personal best 51.08 to qualify for the final, the 23-year old finished under the 51 second mark for the first time to tie for third with France's Camille Lacourt on 50.44 as another Frenchman, Jeremy Stravius, took gold in 49.74.
Also in action on the final night in Denmark were Sophie Allen, Siobhan-Marie O'Connor and Fran Halsall.
Allen lowered her own British record to 1:05.65 as she finished seventh in the 100m breaststroke, while O'Connor - competing in her third individual final of the week - came 10th in the 200m freestyle in 1:56.69.
Meanwhile, Halsall will be disappointed to miss the 50m freestyle podium by just 0.08sec as she touched fourth in the final in 23.91.
Halsall, Allen, Lowe and O'Connor broke the British record in the final event of the meet, the women's 4x50m medley relay as they clocked 1:46.56 to finish fourth.
