Business analysts Plimsoll Publishing say in a new report that the UK's dwindling number of privately owned scientific and laboratory equipment firms are looking more like potential takeover targets
Latest research shows that 434 of the UK's top 728 scientific and laboratory equipment companies remain in private hands, and their values are increasing faster than those of their corporate competitors.
Their exclusivity, niche products and unique services are adding to their attractiveness.
Another more practical factor is also coming into play, according to Plimsoll's senior analyst, David Pattison.
"The increasing age of owners and principals at some of these companies is causing them to consider their choices", said Pattison.
"While many family firms have succession plans in place, an offer for the company at the crucial moment is often listened to sympathetically, as the new generation review their options".
But the big prize for corporate and private raiders is the hidden potential of family-run companies.
Current owners typically strip out 80 percent of profits as fees.
To the value hunter, this is a huge platform on which to build.
But for those who are not averse to the idea of a takeover, their past activity may backfire on them.
"The problem for private companies wishing to sell is that many of them haven't done themselves any favours in the past in terms of promoting the value of the business", said Pattison.
"With the help of professional advisers, they have become very adept at hiding their worth.
"When they go to sell, there simply isn't the evidence to support a high asking price.
"Potential buyers will always make a low offer in this situation because they simply won't believe a company's own unsupported figures".
The changing atmosphere in the industry has an upside and downside for staff and for the wider economy.
On the one hand, if families increasingly withdraw, the sector is in danger of losing the steady corporate stewardship and entrepreneurial drive that has been a cornerstone of the economy for the last 60 years.
On the other, new professional owners, despite bringing more debt and risk, may offer greater focus and drive, benefiting the company and its employees in the longer term.
The latest Plimsoll analysis into the UK scientific and laboratory equipment market cuts through the confusion to give a detailed value and performance rating for each of the 728 companies in the sector.
It is aimed at those looking at their options in the market and anyone thinking of buying or selling a company.
