Keilim24: 5
שְׁלֹשָׁה תַרְבּוּסִין הֵן: שֶׁל סַפָּרִין — טָמֵא מִדְרָס. שֶׁאוֹכְלִין עָלָיו — טָמֵא טְמֵא מֵת. וְשֶׁל זֵיתִים — טָהוֹר מִכְּלוּם.
There are three tarbusin: [The tarbus] of a bloodletter [is susceptible to becoming] tamei with midras [tumah]. [A tarbus] on which people eat [is susceptible to becoming] tamei with corpse-tumah. And [a tarbus] of olives is tahor from any [form of tumah].
Keilim24: 6
שָׁלֹשׁ בְּסִיסָיוֹת הֵן: שֶׁלִּפְנֵי הַמִּטָּה וְשֶׁלִּפְנֵי סוֹפְרִים — טְמֵאָה מִדְרָס. וְשֶׁל דְּלֻפְּקִי — טְמֵאָה טְמֵא מֵת. וְשֶׁל מִגְדָּל — טְהוֹרָה מִכְּלוּם.
There are three bases: [That] which is in front of a bed and [that] which is in front of scribes [is susceptible to becoming] tamei with midras [tumah]. [That] of a delufki [is susceptible to becoming] tamei with corpse-tumah. And [that] of a cabinet is tahor from any [form of tumah].
