- Specialist filtration and environmental technology group Porvair posted an 8% rise in first-half profit, buoyed by rising earnings at its laboratory and metal melt units.

Pre-tax profit rose to £5.2m, as revenue rose 7% to £59.7, or 12% on a constant currency basis.

The company declared an interim dividend of 1.6p per share, up 7% on-year.

'Porvair traded well in the first half of 2018, with a healthy order book for the second half and robust levels of activity,' chief executive Ben Stocks said.

'The business is achieving further organic growth through incremental new product introductions and continues to expand manufacturing capacity to meet demand.'

'We expect to integrate our two first half acquisitions in the balance of the financial year, with both bringing a wider product range to existing customers and adding intellectual property to our portfolio.'

'We see considerable opportunity for growth ahead.'

At 9:40am: [LON:PRV] Porvair PLC share price was +14.5p at 494.5p
