Parker Eclipse® Ultrasound Probe Covers | 38-01 & 38-03 3D/4D

Parker Laboratories Eclipse® Probe Covers are soft, disposable, latex-free covers designed for medical endocavity ultrasound probes and transducers. Each cover is pre-gelled with Aquasonic® 100 Ultrasound Transmission Gel, which makes probe preparation easier and reduces trapped air between the transducer lens and cover.

Choose Eclipse 38-01 for standard endocavity probes or the wider Eclipse 3D 38-03 for larger 3D/4D transducers.

Both configurations are nonsterile, single-use probe covers supplied 100 per box.

Eclipse 38-01 vs. Eclipse 3D 38-03

Which size should I choose?

Select 38-01 when the ultrasound probe fits within Parker's standard tapered cover dimensions.

Select 38-03 when using a larger 3D/4D endocavity transducer that requires the additional width at the open end.

Because ultrasound probe geometries vary by manufacturer and model, compare the probe's dimensions with the cover measurements before ordering rather than choosing by procedure name alone.

Why Are Eclipse Covers Pre-Gelled?

Each Eclipse cover contains Aquasonic 100 Ultrasound Transmission Gel inside.

The pre-gelled design places coupling medium directly between the transducer lens and the inner surface of the cover, reducing setup steps and helping the user eliminate air bubbles over the probe lens.

For additional ultrasound coupling media outside the cover, compare Aquasonic 100 Ultrasound Transmission Gel.

Designed for Endocavity Ultrasound Probes

Eclipse covers are designed to fit most compatible medical endocavity ultrasound probes.

Typical endocavity ultrasound applications may include transvaginal or transrectal ultrasound, provided that the selected cover dimensions, ultrasound-system instructions, and facility procedures are appropriate.

The cover should not be selected solely because a procedure is described as “3D” or “4D.” The key purchasing difference between 38-01 and 38-03 is the physical width of the probe cover.

Nonsterile vs. Sterile: An Important Distinction

Eclipse 38-01 and 38-03 are nonsterile.

They should not be represented as sterile merely because each cover is intended for one procedure.

Current instructions specifically state that Eclipse is nonsterile and is not intended to be sterilized.

If a clinical workflow requires a sterile coupling product elsewhere in the procedure, see Sterile Aquasonic 100 Ultrasound Gel, but follow the probe manufacturer and facility infection-control protocol when selecting probe barriers.

Latex-Free Polyethylene Construction

Parker's current product information and SDS identify Eclipse as a soft, pliable polyethylene probe cover that is not made with natural rubber latex.

This makes Eclipse a useful option where avoiding natural-rubber-latex probe covers is a purchasing requirement.

Parker also describes the cover as non-irritating and non-sensitizing.

How to Apply an Eclipse Probe Cover

Start with a clean, dry probe.

Insert the probe head through the wide end of the pre-gelled cover and gently advance it until the transducer reaches the tip. Remove the protective outer packaging as directed, then smooth the cover over the probe lens so the internal Aquasonic 100 gel forms an even interface without visible air bubbles.

Use the prepared probe promptly according to the ultrasound equipment and facility instructions.

After the procedure, dispose of the single-use cover according to applicable facility and local waste procedures.

Why Eliminate Air Bubbles?

Air trapped over the active transducer surface can interfere with the acoustic interface between the probe and the cover.

After positioning the cover, visually inspect the area over the probe lens and gently smooth remaining bubbles away before use.

This issue is one reason Parker pre-gels the inside of Eclipse covers with Aquasonic 100 rather than supplying the cover completely dry.

Box vs. Case Purchasing

For departments consuming covers regularly, the 600-count case reduces cost per procedure compared with purchasing individual boxes.

Eclipse vs. Generic Dry Probe Covers

Eclipse is most compelling when a facility values pre-gelled setup and predictable Parker dimensions, rather than simply purchasing the lowest-cost disposable sheath.

Frequently Asked Questions

What is Parker Eclipse 38-01?

38-01 is Parker's standard-width Eclipse pre-gelled, latex-free endocavity ultrasound probe cover. It measures approximately 2.37 inches wide at its larger opening, tapering to 1.73 inches, and is 9.5 inches long.

What is Parker Eclipse 38-03?

38-03 is the wider Eclipse 3D probe cover. It measures approximately 3.25 inches at its widest point, tapering to 1.73 inches, with the same 9.5-inch length.

Are 38-01 and 38-03 the same length?

Yes. Both are approximately 9.5 inches / 241 mm long. The principal dimensional difference is the wider opening of 38-03.

How many covers come in a box?

Both 38-01 and 38-03 contain 100 probe covers per box.

How many covers are in a case?

A manufacturer case contains six 100-count boxes, or 600 covers total.

Are Eclipse covers sterile?

No. Parker identifies both 38-01 and 38-03 as nonsterile and not intended to be sterilized.

Are Eclipse covers reusable?

No. They are single-use disposable medical-device accessories.

Are Eclipse probe covers latex-free?

Yes. Parker states that Eclipse covers are not made with natural rubber latex.

What material are Eclipse covers made from?

Current Parker product information identifies the cover material as polyethylene.

Do Eclipse covers already contain ultrasound gel?

Yes. They are pre-gelled internally with Parker Aquasonic 100 Ultrasound Transmission Gel.

Do I still need to remove air bubbles?

Yes. Parker's instructions direct the user to smooth the cover over the transducer and eliminate air bubbles over the lens area before use.

Can I sterilize an Eclipse probe cover?

No. Parker specifically states that Eclipse is nonsterile and not intended to be sterilized.

Which Eclipse cover is best for 3D/4D ultrasound?

Parker 38-03 is the wider configuration intended to accommodate larger 3D/4D endocavity transducers. Always compare the probe dimensions with the cover dimensions and follow the ultrasound-system manufacturer's instructions.

What should I do if the package is damaged?

Do not use a cover if its packaging is damaged or there is evidence of contamination.

Product-use notice: Eclipse 38-01 and 38-03 are nonsterile, single-use probe covers. Follow the current Parker instructions, ultrasound-probe manufacturer requirements and facility infection-control procedures. Probe covers do not replace required cleaning or high-level disinfection procedures for reusable ultrasound transducers.
