Guardian 5000 and 7000 protective case

Quick Answer: The Guardian 5000 and 7000 Protective Case is an in-use cover that fits over the front control area of Guardian 5000 and Guardian 7000 hotplates and stirrers. This Guardian protective case keeps splashes and spills off the controls while leaving openings through which the control knobs can still be used.

Specifications

What the Protective Case Protects

Guardian hotplates and stirrers from OHAUS carry their controls on the front of the housing, which is exactly where drips run when a beaker boils over or a wash bottle is used carelessly. Liquid around knobs and displays can find its way into the housing. An in-use cover shields that area during normal work, which is why covers of this kind are often called in-use covers.

The listing photograph shows a flat, white, slightly translucent shield with a shaped top edge and two round openings side by side. The openings line up with the two control knobs, so the unit can be adjusted without removing the cover. It is a simple part, but a replaceable cover is far cheaper than cleaning chemicals out of a control panel.

The title names both the Guardian 5000 and Guardian 7000 ranges, but model layouts differ within each range, so check that your unit has the two-knob front the cover is shaped for. For stirrers from other makers, a separate protective cover for magnetic stirrers is listed.

Care & Handling

• Fit the case with the unit switched off and cool
• Wipe the cover after every spill, as liquid trapped behind it defeats its purpose
• Keep the cover away from the heated top plate
• Replace the cover if it cracks or becomes brittle

Where an In-Use Cover Helps

• Student labs where solutions are poured close to running hotplates
• Stirring buffers and media that can creep or splash over the vessel lip
• Wet workstations where wash bottles are used around the equipment

Frequently Asked Questions

What does the Guardian protective case do?

It covers the front controls of a Guardian 5000 or 7000 unit so splashes and spills do not reach the knobs and housing while the unit is in use.

Can I use the controls with the case fitted?

Yes. The listing photograph shows two round openings that line up with the control knobs, so the unit can be adjusted with the cover in place.

Does it cover the hot top plate?

No. It protects the control area only. The heated top plate stays uncovered so vessels can be placed on it normally.

Will it fit every Guardian model?

It is listed for the Guardian 5000 and 7000 ranges, but layouts vary between models. Check that your unit has a two-knob front before ordering.

How do I clean the protective case?

Remove it with the unit off, wipe it with mild detergent and water, rinse and dry. Avoid strong solvents, which can cloud or weaken the plastic.

How often should the case be replaced?

Replace it when it cracks, discolours heavily or no longer sits flat. A damaged cover can let liquid through to the controls.
