What does the Amirix LM33-TF cost?

Direct replacement for Varex M-113T mammography X-ray tubes; pricing, value drivers, and negotiation strategies

The Amirix LM33-TF lists at $14,500, marked down from a regular price of $17,000 . This OEM-compatible mammography X-ray tube competes primarily against Varex original equipment and used-market alternatives, with total procurement cost depending heavily on volume, warranty tier, and supply-chain timing. MedSource does not yet have aggregate institutional quote data for this product; this article reflects publicly verifiable manufacturer pricing, distributor list prices, and market context as of May 2026.

What the typical range is

The Amirix LM33-TF carries a current ask of $14,500 USD . The LM33-T variant (non-filament) is also priced at $14,500, marked down from $17,000 . Both units are currently listed as sold out on the manufacturer's direct-to-buyer website, suggesting stock constraints.

For context: the LM33-T is marketed as a direct replacement for the Varex M113-T used in Hologic's Dimensions and 3Dimensions systems, with over 100 units sold since launch . The original Varex M-113T is a 77 mm anode with 222 kJ maximum heat content and biangular rhenium-tungsten-molybdenum target , specifications the Amirix tube is designed to match.

Public distributors selling used M-113T inventory quote exchange prices with upcharges for outright purchase. One refurbished market listing (Radiology OneSource, Dec 2024) showed exchange price for a used M-113T in original housing, with buyout adding $4,000 —indicating used OEM M-113Ts trade in a lower band than new Amirix replacements.

What pushes price up — features, certifications, support tier

Manufacturing origin and QMS compliance: Kailong Medical, founded in 2002 and headquartered in China, manufactures a broad range of diagnostic X-ray tubes, including stationary and rotating anode models, mammography tubes, and side beryllium window designs . Kailong holds GMP, ISO13485, FDA, and CE certifications . Amirix is in the final stages of implementing a Quality Management System (QMS) to become ISO 13485 compliant . These certifications are table-stakes for hospital procurement but do not typically command a premium above base pricing in the OEM-compatible segment.

Warranty terms: The LM33-TF includes a 12-month warranty with 6 months full coverage and 6 months prorated . This matches the standard OEM-equivalent warranty; extended terms (24–60 months) are not listed as available options on the public price sheet.

Thermal performance: The anode design enables elevated heat dissipation, leading to higher patient throughput and longer product life . Rhenium-tungsten compound target ensures constant high dose yield during entire tube life . These are design improvements marketed as durability upgrades, not separately priced add-ons.

Technical integration: Ease of integration is facilitated by extensive technical support . Distributor references mention no separate documentation fees or integration charges on the published price.

What pushes price down — refurbished, older generation, lease, GPO contracts

Refurbished and used M-113T market: Radiology OneSource and Block Imaging actively list used and refurbished M-113T tubes at lower total cost of ownership, though exchange trades (where old tubes are credited) are standard in this market. Buying outright from stock may reduce net cost relative to new, depending on age-of-manufacture and heat unit history.

GPO contracts: No public GSA Schedule or Group Purchasing Organization pricing is currently published for Amirix products. Amirix Imaging holds an exclusive 10-year distribution agreement with Kailong Medical for the LM33-T across North America (U.S., Canada, Mexico) , but GPO/IDN negotiated rates are not disclosed in open literature. Contact Amirix or your GPO directly for volume pricing.

Backorder leverage: One clinical user testimonial notes Varex tubes were on a 2-week back order, with Amirix offering a better price plus overnight shipping and full warranty . Supply scarcity of OEM tubes can shift negotiating advantage toward independents during shortage windows.

Hidden costs — install, training, calibration, consumables, service contracts

Installation and physics acceptance testing: Amirix does not break out installation labor on the public price sheet. Most hospitals contract installation and physicist-conducted acceptance testing to their service partner or biomed staff—typically $1,500–$3,500 per tube depending on system complexity and local labor rates. Budget this separately.

Calibration and QA verification: Clinical users report the machine calibrated and passed physics testing with no issues , but formal acceptance testing (IEC 60601-1 compliance, dose output verification, focal spot analysis) is institution-specific and not included in tube purchase price. Many hospitals outsource this to certified medical physicists (cost: $800–$2,000 per test).

Service and support contracts: Amirix lists 12-month prorated warranty only. Extended service contracts or preventive maintenance plans are not visible on public pricing. Contact Amirix directly for multi-year support tiers.

No consumables in this product category: X-ray tubes do not consume filters, targets, or other wear items until end-of-life. Cost modeling is device lifespan (typically 3–5 years in high-volume clinics), not consumable replacement.

How to negotiate — concrete tactics

1. Volume commitment: Clinics or IDNs planning tube replacement across multiple Hologic systems should quotation requests to Amirix in aggregate. Over 100 units have been sold since launch , indicating volume discounting is likely available but not published. Ask for tiered pricing at 2, 5, and 10 unit commitments.

2. Warranty extension: The published 6-month full / 6-month prorated warranty is short. Negotiate extended term (24 or 36 months full) or performance guarantees (e.g., warranty void only on manufacturing defect, not installation damage) as a no-cost add-on when bundling multiple units.

3. Bundled terms: Request inclusion of:

   • Expedited shipping (already reportedly offered)
   • Technical documentation and integration guides
   • On-site commissioning call with Amirix engineering (not service labor, but guidance)
   • Deferred payment terms (45–60 days instead of net 30) for large orders

4. Competitive bid: Simultaneously quotation existing OEM channels (Hologic service, Varex direct) and used M-113T refurbishers. Document baseline Varex pricing to anchor negotiation. Amirix's $14,500 list is approximately 15% below the stated prior price of $17,000, indicating room for further discount off current ask.

5. Timing leverage: Stock appears limited (sold out on direct channels as of May 2026). If lead time is not critical, request quotes 30–60 days out to improve pricing; if urgent, accept list price but push on warranty and support terms.

6. Service relationship: If your facility is a high-volume imaging center, propose a longer partnership (e.g., "preferred replacement vendor for 3 years") in exchange for volume commitment. Amirix, as a newer entrant, may prioritize customer retention over transaction margin.

When the price feels off — red flags

• Price under $12,000: OEM-equivalent mammography tubes meeting IEC 60336 and FDA Class II requirements do not sustainably wholesale below this level new. Extreme discounting may signal gray-market, salvaged-tube, or counterfeit inventory.

• No visible warranty or QMS documentation: Confirm that your distributor or vendor has access to Kailong and Amirix certificates (GMP, ISO 13485, FDA 510(k) clearance if applicable). Absence of these documents suggests non-authentic product.

• Shipping costs > $1,000 for a single unit: Mammography tubes are fragile (proper packaging is critical) but should not incur freight charges > 5–7% of device cost. Request itemized shipping and handling.

• Rapid price volatility: Because Amirix is 2024-founded and stock is reportedly constrained, monitor pricing if you intend repeat procurement. If prices swing > 10% month-to-month, demand a fixed quote with validity period (minimum 30–60 days).

• No reference installations: Over 100 units have been sold , but ask your vendor for 2–3 named clinical references in your region. Newer manufacturers sometimes overstate field deployment; confirmable installations reduce adoption risk.
