Sartorius 6971790 Adapter: Which Quintix and Practum It Fits

Aug 29

3 min read

A Quintix that will not power is not automatically a dead analog board. The factory brick All Scales USA stocks in Cypress is Sartorius 6971790 — $79. Live GSC slug: sartorius-6971790-universal-power-adapter-for-quintix-and-practum-balances-1. A duplicate slug without -1 is the same $79 adapter. Do not double-order. Thirty-two on this listing. This post is which body it fits, and how we confirm a live balance before we ship.

Which Quintix and Practum call out 6971790

The live All Scales page names Quintix, Practum, Secura, and first-generation Entris balances that call out 6971790. The balance is not in the carton. A battery is not in the carton. Output is the universal module Sartorius specified for those bodies. We confirm the part number on the old brick and on the rear rating plate before we ship. Manufacturer pages we actually fetched: Sartorius laboratory balances and Sartorius Practum. Newer Quintix Pro cartons call a different supply (YEPS01-class). If your tag says YEPS01, 6971790 is the wrong brick.

Two live balances we will match against in Cypress: the Sartorius Practum124-1S — 120 g × 0.1 mg, $1,998 and the Sartorius Quintix3102-1S — 3100 g × 0.01 g, $2,149. Photograph the barrel, the voltage, and the part number. We would rather miss a $79 sale than cook a $2,000 head.

How Cypress confirms before shipping

Email pete@allscales.com three photos: the dead brick label, the balance rear plate, and the barrel in the socket. Or bring the brick to 21249 FM 529 Rd.

Part number on the brick — 6971790, not a look-alike 12 V wall-wart.
Voltage and polarity on the balance tag. A reversed barrel is how a Practum comes back dead.
Series on the nameplate — Quintix / Practum / Secura / first-gen Entris. A later Quintix Pro is a different supply conversation.
Country blades. This is the universal module. If you need a specific wall blade, say which country.

Leaves: Sartorius balances and parts, cells & indicators. A 6 V SLA swap is a different post: Leoch DJW6-5.0. Always MNM Scales in full when we talk house kits — this adapter is Sartorius, not a house kit.

What we will not ship blind

We will not guess a Secura versus an Entris II from a blurry photo. We will not send 6971790 as a universal for every Sartorius ever made. If the live balance is not on our shelf, we still want the tag. On-site power checks ride with Houston calibration and scale calibration Houston. No ISO 17025. No A2LA. No truck scales.

The duplicate $79 listing

Two live slugs, one adapter. The GSC URL ends in -1. The twin without -1 is $79 as well, SKU 78-GV36-NKL3. Thirteen on that twin. If a search lands you there, it is the same 6971790 conversation. We will not publish a second adapter post for the clone.

Secura and first-generation Entris are on the live spec table with Quintix and Practum. That does not mean every Entris II or every current Secura in a 2026 catalog still prints 6971790. The rating plate is the rule. A lab that swapped bricks from a drawer is how a 12 V look-alike cooks a 15 V input. We ask for the dead brick even when the balance name sounds right.

If we also stock the balance you are powering, we would rather ship the brick with a known-good body than as a spare in the dark. Practum124-1S and Quintix3102-1S are the two we named because they are live, in stock, and on this site. Other Quintix / Practum slugs exist. Confirm before checkout. Leaf: Sartorius balances.

Sister catalog: ek1200i. Manufacturer links stay on sartorius.com — not a dealer brochure and not a third-party PDF host. If the live balance is in Houston and will not power, the service path is the Cypress call, not another adapter.

On the Cypress bench we also check that the barrel seats fully. A loose barrel that arcs is not a new analog board. If the live Quintix still will not boot on a known-good 6971790, the next call is the board, not a second brick. All Scales USA will say that out loud. Address 21249 FM 529 Rd. Phone (832) 766-5410. That is the whole point of confirming the live balance before the spare ships.
