TEKNOMEK LIMITED

£225

Our Grant PV-1 vortex mixer is a compact vortex device engineered for rapid, reproducible mixing of liquid samples in tubes ranging from 0.2ml up to 50ml. Its low-profile design and small footprint make it ideal for busy bench spaces or confined lab environments. The unit operates at variable speeds from 750 to 3,000 rpm, allowing gentle mixing for resuspension or vigorous vortexing for pellet disruption. Users may choose either continuous operation or touch-activated mode via a pressure-sensitive cup - in touch mode, mixing begins as soon as the tube contacts the cup, simplifying workflow and

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as TEKNOMEK LIMITED, number 02054645. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
Not yet checked.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
Not established. Many companies file a statement rather than naming a controlling shareholder.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
