Muha Meds 2g Disposable Empty — B2B Specs, Compliance & QC Guide (2025)

This page is an engineering-first buyer’s brief for muha-compatible 2-gram empty disposable hardware. It explains what the term means in B2B contexts, which specifications matter, how to verify materials and seals, and how to run an incoming-QC you can defend to auditors. We sell empty hardware only—no oil, no filled products.

Scope & Compliance. Standards referenced include ISO 10993 (biocompatibility strategy for mouth-/seal-contact), RoHS/REACH chemical compliance, UN 38.3 (cells in transport, if applicable), UL 8139 / IEC 62133-2 (system safety, if applicable). Local regulations vary—buyers remain responsible for finished-goods labeling/testing.

What “Muha Meds 2g Disposable Empty” Usually Means

In wholesale conversations, this phrase is widely used to describe muha-style / muha-compatible empty shells—i.e., housings and components with a similar form factor that are intended for white-label filling by licensed packers. Unless explicitly stated by the brand owner, these parts are not official filled consumer goods. To avoid confusion in audits and shipments, specify “empty hardware only” in your purchase order and technical attachments.

Exploded-view placeholder: housing, mouthpiece, ceramic core, seals, air path, USB-C end cap. (Illustration for component naming consistency.)

Key Specifications & Materials (With a Fill-Ready Checklist)

The table below shows typical fields B2B buyers validate before pilot filling. Values are examples—use your target viscosity, coil, and draw profile to finalize the acceptance ranges.

Item	Target/Range	Why it matters
Chamber Volume	2.0 g (≈ 2.0 mL) nominal	Aligns label claims and dose counts; check gravimetric capacity tolerance.
Ceramic Core	Resistance e.g. 1.2–1.6 Ω @ 25 °C	Determines power envelope and thermal profile for thick oils.
Air Path	Single/dual channel; ID e.g. 1.6–1.8 mm	Predicts draw-resistance and condensate behavior.
Seals / O-rings	FKM / Silicone; Shore A 50–60	Chemical compatibility and long-term compression set drive leak risk.
Mouthpiece (contact part)	PCTG / PC (food-contact grade)	Subject to your ISO 10993 strategy (cytotoxicity/irritation/sensitization).
Preheat Function	0.5–1.0 s soft preheat	Supports cold starts; reduce clog events without charring.
Draw-Resistance	Recommended e.g. 90–130 Pa @ 17.5 mL/s	Keep user experience consistent across lots; validate with Gage R&R.
Torque Windows	e.g. Mouthpiece 6.0–7.5 N·cm	Prevents under-seal leaks and over-compression damage.

For a deeper dive on seals, torque windows, and leak risk modeling, see your in-house reference on Seal Integrity & Leak Prevention.

Seal Integrity & Leak Prevention (Torque Windows that Work)

Most field returns come from either insufficient compression at the mouthpiece or tank joint or over-compression that nicks an O-ring and warps the cap. Your SOP should define a go/no-go torque window per joint and verify it at line start, after shift breaks, and on changeovers. Pair torque checks with a 48-hour room-temp rest and a simple 20↔45 °C two-cycle thermal excursion—both are inexpensive and strong predictors of shelf stability.

Combine torque control with correct O-ring material (FKM/Silicone) and lubrication policy (if used). Document the exact part number and durometer on your drawing to prevent silent vendor substitutions.

Illustrative “sweet spot” for torque: left = micro-leaks, right = O-ring damage. Define windows by test, not by feel.

If you need a ready template for draw/torque repeatability studies, see the in-depth methods in Gage R&R & Uncertainty for Vape Hardware Tests.

Biocompatibility & Chemical Compliance (ISO 10993, RoHS/REACH)

Treat the device as a set of contact classes: mouth-contact plastics, liquid-contact seals, and neutral structural parts. Build your ISO 10993 strategy around the first two. In practice, buyers request supplier declarations, bill-of-materials with contact identification, and—where appropriate—third-party test reports for cytotoxicity/irritation/sensitization on representative materials or finished components. For RoHS/REACH, require dated declarations and spot-check high-risk parts (PCBA solder, plating, pigments).

Align nomenclature between your RFQ, drawings, and labels. Reserve a dedicated zone on the artwork for QR, anti-counterfeit, and finished-goods COA links supplied by the licensed filler.

Incoming QC SOP: AQL, Airflow & Functional Checks

Incoming QC for empty hardware should be boring, short, and predictive. Use a standard AQL plan (e.g., Critical 0; Major 2.5; Minor 4.0), then run three functional screens on the sample: (1) draw-resistance to target window; (2) seal check after 48-hour rest and a simple thermal excursion; (3) preheat function sanity check without oil to verify control logic. Keep results in a single lot traveler that flows into production records.

Check	Method	Pass Criteria (example)
Draw-Resistance	17.5 mL/s through calibrated orifice; gauge logged	90–130 Pa; Gage R&R < 10%
Seal / Leak	48 h rest + 20↔45 °C ×2; visual & mass check	No visible seep; Δm ≤ 10 mg/unit
Torque Windows	Click-type or digital torque driver	Each joint within spec window

A step-by-step template (sampling tables + airflow checks) is available in Incoming QC for Empty Vape Hardware (AQL & Airflow Tests).

Safe Voltage & Preheat Ranges for 2g Ceramic Cores

Keep the focus on coil temperature control and flavor preservation. For most 2 g ceramic cores paired with viscous extracts, a conservative starting point is:

Preheat: 0.5–1.0 s at a gentle setting—just enough to warm the wick and clear cold starts.
Puff Voltage: 2.6–3.4 V depending on coil resistance and viscosity. If you notice browning or burnt notes, step down in 0.1 V increments; if clogging increases, step up preheat slightly rather than voltage.

Record power curves during pilot runs so QC can spot drift early. Avoid “hot” presets designed for small-volume tanks—2 g chambers respond slower and punish over-power quickly.

Procurement Checklist (Copy-Paste for Your RFQ)

Bill of materials with contact-part identification (mouth & seal). Provide ISO 10993 plan or material test summaries.
RoHS/REACH supplier declarations (dated), plus any recent third-party reports for high-risk parts.
Drawings with O-ring part numbers, durometer, and torque windows for each threaded/press-fit joint.
Gage R&R method for draw/torque; target repeatability <10%.
Preheat profile and allowed voltage range; no firmware changes without written notice.
Pilot build: 200–500 pcs, ship with lot traveler, AQL results, and rework/DOA policy.
Artwork zones reserved for QR/anti-counterfeit and filler-supplied COA/labeling.

FAQ

Is this an official Muha Meds product?

No. “Muha Meds 2g disposable empty” is common trade shorthand for muha-style/compatible empty shells intended for white-label filling by licensed packers. We supply empty hardware only.

Can you ship it filled?

No. We do not supply oils, cannabinoids, or filled finished goods. Buyers are responsible for local regulatory compliance, finished-goods testing, and labeling.

How do we minimize leaks at scale?

Specify O-ring material/durometer, lock in joint torque windows, verify with 48-hour rest plus simple temperature cycling, and run draw-resistance control charts on each lot.
