Predictika · OEM liquid handling module orders

An AI sales agent's analyzer module order, checked before it goes out

An AI sales agent prepares an order for liquid handling and reagent modules that an instrument maker is integrating into its analyzer. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published module data sheets and returns a verdict, every reason and the figures it computed.

Scope: Stratec OEM modules: Air and Liquid Displacement Pipettors, LCM Pump 500 and 5000, Syringe Pump, Peristaltic Pump, Degasser, Bulk Liquid Supply, Direct Plumbing Kit, Reagent Rack & Bay and Reagent Bottle & Docking Station, checked against their data-sheet ranges and capacities. See everything this validator covers

This validator models orders for Stratec's OEM liquid handling and reagent modules, from the published Stratec data sheets, not just the scenarios shown below.

  • Dispense range — the dispense volume must lie in the range the data sheet gives for the selected module: 1 to 1,000 microliters for the Air and Liquid Displacement Pipettors, 20 to 500 for the LCM Pump 500 and 100 to 5,000 for the LCM Pump 5000.
  • Counts and capacities — up to 15 Syringe Pumps working together over the communication interfaces, up to three cassettes on a Peristaltic Pump (with only the listed gearbox flow rate ratios: 1:4, 1:7, 1:10, 2:5, 2:11, 1:2, 1:3), 8 reagent racks per Reagent Rack & Bay loading bay holding 2 reagent cartridges each, 8 docking stations for 4 different liquids on a Reagent Bottle & Docking Station, and Bulk Liquid Supply containers up to 10 liters (transfer) and 3.8 liters (intermediate).
  • Flow and supply — Degasser flow of 10 to 500 milliliters per minute, and a Direct Plumbing Kit that needs an inlet pressure of 1 to 10 bar (the data sheet also lists a required inlet flow rate of 3 liters per minute, which is not checked).
  • Stated figures — the number of reagent cartridges the order states is compared with two per rack.

Any order for these modules that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Stratec publishes no price list for its OEM modules, so this validator produces no price build-up or line-item list), electrical, size or weight budgets, tube kit choices, tip choices, chemical compatibility of liquids, Stratec's finished analyzers and platforms (Gemini, FNX nova, KleeYa) and its custom development work, and regional or contract terms.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
A dispense volume outside the range of the selected moduleOnly with care
A per-module volume range has to be kept as a product rule, and the module and the volume sit on different lines of the order.		The module and the dispense volume are in one request and compared with the data sheet on every call.
A count or capacity above what a module holds (racks, docking stations, liquids, cassettes, pumps working together)Only with care
Each limit is a separate cardinality rule that has to be maintained per module and kept in step with the data sheets.		Every count is in one request and checked against the published capacity on every call.
A stated cartridge count that must match the racksOnly with care
A stated figure is a free-entry field; a rule can compare it with two cartridges per rack, but only if the stated figure is a field on the order, which it rarely is.		The stated cartridge count travels with the order and is compared with the computed figure on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the order; approval findings need a person to sign off; everything else is computed.

    
1A dispense of 1,001 microliters is outside the published range of 1 to 1,000 microliters for the selected module.
2A dispense of 800 microliters is outside the published range of 20 to 500 microliters for the selected module.
3A dispense of 10 microliters is outside the published range of 20 to 500 microliters for the selected module.
4A dispense of 99 microliters is outside the published range of 100 to 5,000 microliters for the selected module.
5The Syringe Pump data sheet lists communication interfaces that selectively work with up to 15 Syringe Pumps; the order has 16 Syringe Pumps working together.
6A Peristaltic Pump takes up to three cassettes; the order has 4.
7A flow rate ratio of 1 to 5 is not one of the gearbox ratios Stratec lists (1:4, 1:7, 1:10, 2:5, 2:11, 1:2, 1:3).
8A Reagent Rack and Bay loading bay holds 8 reagent racks; the order has 9.
9The order states 10 reagent cartridges, but 6 reagent racks hold 12 (2 per rack).
10The Reagent Bottle and Docking Station data sheet lists 8 docking stations; the order has 9.
11The Reagent Bottle and Docking Station handles 4 different liquids; the order has 5.
12The Bulk Liquid Supply transfer container is listed for up to 10 liters; the order has 12,000 milliliters.
13The Bulk Liquid Supply intermediate container is listed for up to 3.8 liters; the order has 4,000 milliliters.
14The Degasser flow rate range is 10 to 500 milliliters per minute; the order has 5.
15The Direct Plumbing Kit requires an inlet pressure of 1 to 10 bar; the order has 12 bar.
16The Syringe Pump data sheet lists communication interfaces that selectively work with up to 15 Syringe Pumps; the order has 20 Syringe Pumps working together.
17A Reagent Rack and Bay loading bay holds 8 reagent racks; the order has 10.
18The order states 12 reagent cartridges, but 10 reagent racks hold 20 (2 per rack).

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for liquid handling and reagent modules that an instrument maker is integrating into its analyzer. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published module data sheets and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please prepare an order for Stratec OEM modules for the partner analyzer: a Reagent Rack and Bay. The order states 20 reagent cartridges. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with one finding, all in one answer. A Reagent Rack and Bay loading bay holds 8 reagent racks; the order has 10.
    6. 
      
  6. The validator returned one blocking finding in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the order are checked against each other.
    7. 
      
  7. What this shows: for a count or capacity above what a module holds (racks, docking stations, liquids, cassettes, pumps working together), a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the reagent racks in the bay to 8.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The order states 20 reagent cartridges, but 8 reagent racks hold 16 (2 per rack).
    12. 
      
  12. One finding cleared, but the change brings a different blocking finding: stated reagent cartridges differ.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the stated reagent cartridges to 16.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the order.
    18. 
      
  18. One problem caught in one call, fixed in two passes, and a clean order. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
