Question 1

Which tablets can be crushed?

Accepted Answer

Many immediate-release tablets can be crushed, but some must never be — including slow-release, enteric-coated and sublingual tablets. Always check with a pharmacist before crushing any medication. Our Safe Crushing Guide explains which types to avoid and why.

Question 2

How fine is the crushed powder?

Accepted Answer

The Silent Knight's patented dual-action movement first crushes, then grinds tablets into a fine, consistent powder in seconds — easy to mix into soft food or liquid, and suitable for feeding tubes when a pharmacist approves.

Question 3

Can I crush several tablets in one pouch?

Accepted Answer

Yes. You can place several tablets into a single Silent Knight pouch and crush them together. Use a fresh pouch for each patient and each medication round to prevent cross-contamination.

Question 4

How do I give the medication once it's crushed?

Accepted Answer

Give it straight away, mixed into about a teaspoon of soft food such as yoghurt or apple sauce, or into water — only when the pharmacist agrees that is suitable for the medicine. Our Safe Crushing Guide covers this in detail.

Question 5

How big is the Silent Knight?

Accepted Answer

It is a compact countertop unit that sits comfortably on a medication trolley, in a treatment room or on a kitchen counter. It needs no electricity or batteries, so it can be used anywhere. Contact us for the full specification sheet.

Question 6

Is it manual or electric?

Accepted Answer

Fully manual. The ergonomic lever handle does the work with minimal effort, and an internal shock absorber makes operation smooth and quiet — no motors, charging or noise.

Question 7

How long does the machine last?

Accepted Answer

The Silent Knight has been in daily use in hospitals and care homes for over 30 years. It is built with surgical-quality stainless steel crushing components and a solid aluminium base, and needs no servicing beyond normal cleaning.

Question 8

Is the Silent Knight CE marked?

Accepted Answer

Yes. The Silent Knight is a Class I medical device under the EU Medical Device Regulation (MDR), CE marked and registered in EUDAMED. Full details are on our Regulatory pages.

Question 9

Are the instructions available in my language?

Accepted Answer

Yes. The instructions for use are available in nine languages — English, Spanish, Portuguese, French, German, Italian, Dutch, Polish and Swedish — on our IFU & EUDAMED page.

Question 10

What paperwork can distributors get?

Accepted Answer

Distributors can download the IFU in all nine languages, the Certificate of Conformity, material safety information and EU authorised representative details from our Regulatory section — everything needed for EU compliance.

Question 11

Is the Silent Knight latex-free?

Accepted Answer

Yes. Both the machine and the pouches are completely latex-free, and the device is classified as non-hazardous.

Question 12

How does it prevent cross-contamination?

Accepted Answer

Every dose is crushed inside a sealed Silent Knight pouch, so medication never touches the machine. The pouch isolates each patient's medication completely — no residue, no mixing between patients.

Question 13

Can it be used for hazardous medicines?

Accepted Answer

For hazardous drugs, use the HD Safety Seal pouches, which seal in the crushed medication, and always follow your facility's handling protocol. The pouch system keeps staff from contacting medication dust.
