New logo required for scientific health care company

WITHIN 48 HRS IF POSSIBLE PLS? proposing to update, modernise & re-brand a company logo which is a little tired & old fashioned. Ideally would like 2 or 3 options to show to the client, even if in draft stage,
The company is well established in the scientific field, and carry out antioxidant ratings on products & foods. In addition, this company will be selling their own health supplements, plus offering ‘at home’ tests.
So, this is a well respected, well established British scientific company who sell their products & services to both business to business, and end consumers.
As the name is Knight Scientific, a Knight’s Shield could possibly be incorporated into the logo as they have currently if this works visually? Would like to see something clean, sharp, dynamic, trustworthy, ‘scientific’, etc, but still ‘cool’.
Will be Re branding and updating all company literature /posters/website/packaging etc, so scope for a lot more work for you following this.
Colours- was thinking dark blue & grey/silver to be in line with old current logo , but obv v happy to see what suggestions you have. Will be updating the website also, but in the meantime the link to the website is as follows. Pls msg me if you have any questions at all. Thanks
