SLS / SAMPLE REQUEST

Your sample. Your request. On your phone.

A lightweight app for sample testing requests and quotations. The same laboratory and shared request numbering, one tap from your home screen.

  1. 01 Sample details
  2. 02 Optional attachment
  3. 03 Send in WhatsApp
Online

Uploading an attachment, reserving a number, and opening the WhatsApp request require an internet connection. Requests are not sent automatically when connectivity returns.

Your request receives a sequential number starting at 0101, then opens WhatsApp with its number and details. Review the message and press Send in WhatsApp; reserving a number does not mean the laboratory received the request.

SAMPLE REQUEST / SLS

The first step is clear information.

Enter your sample details and send your request directly to SLS on WhatsApp to confirm test scope and a quotation.

Your request receives a sequential number starting at 0101, then opens WhatsApp with its number and details. Review the message and press Send in WhatsApp; reserving a number does not mean the laboratory received the request.

Your file uploads when you submit, and its download link is included in the WhatsApp message. The link is not an in-chat media attachment; use the file-sharing button on a supported phone to send the actual file.

The website stores your request number, reservation token, and selected attachment with its metadata, not customer details. Submitting agrees to uploading and sharing the attachment link with the laboratory; anyone holding the link can download it. Do not attach sensitive documents.

Put SLS on your home screen.

Added to your home screen. No APK download or app store required.
